Ask 1.1 PRODUCT DESCRIPTION AND
FEATURES
•
•
SECTION 1 INTRODUCTION
The Mini -Mate2 is a temperature/humidity control system
designed to be installed above a 2' x 4' ceiling grid system.
The unit is available as a split system evaporator, and is to
be matched with an Indoor Centrifugal Condensing Unit,
Outdoor Prop Fan Condensing Unit, or Indoor
Water /Glycol Condensing Unit. A self contained Chilled
Water Fan Coil is also available.
1.1.1 Controls
The Mini -Mate2 system includes a wall - mounted display
panel that includes a liquid crystal display (LCD) screen
and an 8 membrane keypad. The control is menu - driven for
ease of use. Figure 14 (Section 3- Microprocessor Control)
depicts the complete menu tree for the control. All control
set points and alarm set points are programmable.
1.1.2 Evaporator System Components
DX Evaporator Section
The evaporator section includes the evaporator coil,
thermostatic expansion valve, filter drier, and blower. The
evaporator coil is constructed of copper tubes and
aluminum fins and is designed for the high sensible heat
ratio required for electronic equipment. Room air
circulation is accomplished by a double inlet, direct drive
centrifugal blower that has been dynamically balanced. The
blower motor has self - aligning bearings and lifetime
lubrication.
Chilled Water Model
The Chilled Water model is self - contained and is designed
for use with an existing chilled water loop. It contains a
chilled water coil and a slow open/close solenoid valve to
control the flow of chilled water.
Two air delivery rates (high and low) are specified for
either unit. An optional single -speed high static blower box
is available to overcome high static pressures.
1.1.3 Condensing Components
The condensing unit is connected to the evaporator unit by
two refrigerant lines and a low voltage control cable. The
condensing unit requires a power source and a power
disconnect switch. A single point power kit is available for
close coupled units. Power options and requirements are
shown in Section 2.2 SYSTEM DATA.
Air Cooled Condensing Units (Indoor Centrifugal)
The Air Cooled Condensing units (MCD models) include:
scroll. compressor with crankcase heater, high pressure
switch, condenser coil, and Lee -Temp flood back head
pressure control with receiver.
1
Air Cooled Condensing Unit (Outdoor Prop Fan)
Outdoor Air Cooled Condensing Units (PFC models)
include: scroll compressor with crank case heater, high
pressure switch, condenser coil, filter drier, propeller fan,
and Lee —Temp floor back head pressure control.
Water /Glycol Condensing Unit (Indoor)
The Water /Glycol Cooled Condensing units include: scroll
compressor with crankcase heater, high pressure switch,
coaxial condenser, and 2 -way regulating valve. The
Water /Glycol Cooled condensing unit is designed to
operate with city water, cooling tower systems, or drycooler
systems. Drycooler and pumps are selected separately.
1.2 Optional Equipment
Canister Humidifier
The optional, factory installed steam generating humidifier
adds pure water vapor to the room air to control humidity.
Room humidity setpoints are established by the user. The
humidifier components include: a steam canister
(replaceable), control board, inlet strainer, fill and drain
solenoids.
Electric Reheat
The optional electric reheat is installed and tested at the
factory. The reheat feature is energized when required to
heat room air or to control room temperature during
dehumidification. A safety thermostat prevents the reheat
from exceeding temperature limits,
SCR Electric Reheat
The optional electric reheat is pulsed rapidly to provide
precise temperature control, while cooling is locked on. A
safety thermostat prevents the reheat from exceeding
temperature limits.
Hot Water Reheat
The optional hot water reheat circulates building hot water
through a y- strainer, solenoid valve and finned -tubed
heating coil to provide reheat.
Hot Gas Bypass (Condensing Units)
This optional system bypasses hot gas around the
compressor directly to suction to provide capacity control
and reduce compressor cycling. System includes liquid
injection valve to maintain proper suction superheat.
Free - Cooling Coil
A separate source of chilled water (or cold tower water) can
be used to provide cooling. Upon loss of the chilled water
source, cooling is switched to DX cooling.
1.2.1 Ancillary (Ship Loose Accessories)
Smoke Detector
If return air smoke is detected, the unit alarm panel
(display) emits an audible signal and the unit shuts down.
Firestat
When the return air temperature limit of approximately
125 °F (51.7 °C) is exceeded the unit shuts down.
Filter Clog
An adjustable pressure differential switch emits an audible
signal when high differential pressure (e.g., dirty filters) is
detected.
Single Point Power Kit
A Single Point Power Kit allows the connection of a system
(evaporator and condensing unit) to a single power source
when the units are close coupled. The kit includes a
junction box with fuse block, evaporator and condenser
wiring, and fuses.
Refrigerant Line Sweat Adapter Kit
This kit includes the compatible fittings required (two
suction and two liquid line connections) when using field
supplied interconnecting refrigerant lines, instead of the
pre - charged line sets.
Pre - Charged Refrigerant Line Sets
Pre - charged refrigerant line sets are available in 15 and 30
foot lengths for 2 and 3 ton systems. They are factory-
charged and sealed. They are used to connect the evaporator
to remote Air Cooled or Water /Glycol Cooled condensing
units. Each set includes an insulated copper suction line and
a copper liquid line with fittings.
Air Discharge Plenum
A molded plastic 4 -way air discharge plenum attaches to
the evaporator and eliminates the need for ductwork in 2
and 3 ton systems. The plenum protrudes through a
suspended ceiling directing the conditioned air throughout
the room. The plenum includes a 4" deep filter and
sheetmetal block -off plates for covering the duct openings
of the evaporator.
Duct Kit with Return Air Filter Box
A return air filter box with duct flange, 4" (102mm) filter,
and a supply air duct flange are provided for ducting the
evaporator air.
Condensate Pump Kit
A condensate pump is required when the evaporator is
installed below the level of the gravity-fed drain line.
Components include: the pump; check valve; sump; level
sensor; float switch; and controls. The condensate pump kit
is field- mounted to the side of the evaporator housing,
where it automatically controls the water level in the sump.
High Static Blow Box
The high static blower box attaches to the end of the
evaporator section to provide up to 2.0" external static
pressure. It is required that the added static pressure occur
downstream of the blower box.
1.2.3 Remote Monitoring and Control
Remote Monitoring and Control
Liebert can provide a variety of remote monitoring and
control devices to enhance your Mini -Mate2 system. These
include water detection, remote monitoring of a single unit,
and remote control/monitoring of multiple units.
Remote Sensors
Remote temperature/humidity sensors can be mounted in
the controlled space or in ductwork and includes 30 feet of
control cable.
•
SECTION 2
NOTE: Before installing unit, determine
whether any building alterations are required
to run piping, wiring, and ductwork. Carefully

drawings of individual units for proper
clearances.
2.1 INSTALLATION CONSIDERATIONS
The evaporator unit is usually mounted above the
suspended ceiling in the space to be conditioned. Ducted
systems may be located in a different room. Refer to
Figures 1 and 2 for possible configurations. The condensing
unit may be:
• Air Cooled Centrifugal Fan can be mounted remotely
or close coupled to the evaporator in the ceiling space.
• Air Cooled Propeller Fan Condensing Units which are
normally mounted outdoors.
• Water /Glycol cooled which is mounted indoors,
mounted remotely or close coupled to the evaporator in
the ceiling space.

2.1.1 Room Preparation
The room should be well insulated and must have a sealed
vapor barrier. The vapor barrier in the ceiling and walls can
be a polyethylene film. Paint on concrete walls and floors
should contain either rubber or plastic.
NOTE: The single most important
requirement for maintaining
environmental control in the conditioned
room is the vapor barrier.
Outside or fresh air should be kept to a minimum when
tight temperature and humidity control is required. Outside
air adds to the cooling, heating, dehumidifying and
humidifying loads of the site. Doors should be properly
sealed to minimize leaks and should not contain ventilation
grilles.
2.1.2 Location Considerations
NOTE: Temperature and humidity sensors
are located in the wall box. Carefully
select a position for the box where
discharge air DOES NOT directly blow on
the sensors.
CAUTION: Units contain water. Water
leaks can cause damage to sensitive
equipment below. DO NOT MOUNT
UNITS OVER SENSITIVE EQUIPMENT.
A field supplied pan with drain must be
installed beneath ducted cooling units and
water /glycol cooled condensers.
Note: Do Not mount indoor condensing
units in areas where normal unit operating
sound may disturb the working environment.
Locate the evaporator unit over an unobstructed floor space
if possible. This will allow easy access for routine
maintenance or service. Do not attach additional devices
(such as smoke detectors, etc.) to the housing, as they could
interfere with the maintenance or service.
When using the optional air distribution plenum, avoid
locating the evaporator unit in confined areas that affect the
air flow pattern. Such locations could cause short cycles,
down drafts, and air noise. Avoid locating the unit in an
alcove or at the extreme end of a long, narrow room. Avoid
installing multiple units close to each other. This could
result in crossing air patterns, uneven loads, and competing
operating modes.

2.3 EQUIPMENT INSPECTION (UPON
RECEIPT)
When the unit arrives, do not uncrate equipment until it is
close to its final location. All required assemblies are
banded and shipped in corrugated containers. If you
discover any damaged when you uncrate the unit, report it
to the shipper immediately. If you later find any concealed
damaged, report it to the shipper and to your Liebert
supplier.
2.4 INSTALLING THE CEILING UNITS
WARNING: BE SURE THE
SUPPORTING ROOF STRUCTURE IS
CAPABLE OF SUPPORTING THE
WEIGHT OF THE UNIT(S) AND THE
ACCESSORIES. (See Section 2.2, System
Weights.)
BE SURE TO SECURELY ANCHOR
THE TOP ENDS OF THE SUSPENSION
RODS. MAKE SURE ALL NUTS ARE
TIGHT.
The evaporator unit and condensing unit are usually
mounted above the ceiling and must be securely mounted to
the roof structure. The ceiling and ceiling supports of
existing buildings may require reinforcements. Be sure to
follow ill! applicable codes. Use field - supplied threaded
suspension rods and 3/8 -16 factory hardware kit.
Recommended clearance between ceiling grids and building
structural members is unit height plus 3 inches.
Install the four field- supplied rods by suspending them from
suitable building structural members. Locate the rods so
that they will align with the four mounting holes in the
flanges that are part of the unit base.
Using a suitable lifting device, raise the unit up and pass
the threaded rods through the four mounting holes in the
flanges that are part of the unit base.
Attach the threaded rods to the unit flanges using the
supplied nuts and grommets. (See Figure 4).
The rubber grommets provide vibration isolation.
1. First, use the plain nuts to hold unit in place. Adjust
these nuts so that the weight of the unit is supported
evenly by the four rods, does not rest on the ceiling
grid, and to ensure the unit is level.
q
NOTE: The units must be level in order to drain
condensate properly.
2. Second, use the shake -proof nuts to "jam" the plain
nuts.
Close Coupled Installations
If the evaporator and condensing units are to be mounted
back -to -back (close coupled), hang each unit before
connecting them together. Align four bolt holes in the
condenser with cage nuts in the evaporator. Insert rubber
spacers and secure with provide hardware. Align the
refrigerant connections and tighten them as described in
Piping Connection and Coolant Requirements. (See Figure
5 and Figure 8).

2.4.2 Evaporator Air Distribution
Filter Box
The optional filter box is available for the unit and mounts
directly to the return air opening of the evaporator. The 2
and 3 ton filter box is supplied with a filter measuring 20 in
x 20 in. x 4 in.
Plenum Installation
The 2 and 3 ton non - ducted evaporators can use the
optional ceiling- mounted plenum to provide four -way air
distribution. The plenum fastens to the bottom of the
evaporator. The plenum includes a 16 in. x 25 in x 4 in
filter.
1. The evaporator should be mounted above the
bottom of the T -bar supports with at least 30 in.
clearance from return air end to wall (for replacing
filter).
2. Check the contents of the plenum kit.
3. Carefully follow the installation instructions included
with the plenum kit.
Q
Note: Do not operate the unit without filters
installed in return air system.
Connections for Ducted Systems
In a ducted configuration, the direct drive evaporator has a
maximum allowable external static pressure of 0.3" wg (7.6
mm). Use flexible ductwork or non - flammable cloth collars
to attach ductwork to the unit and to help control the
transmission of vibrations to building structures. Insulation
of ductwork is vital to prevent condensation during the
cooling cycle. The use of a vapor barrier is required to
prevent absorption of moisture from the surrounding air
into the insulation.
If the return air duct is short, or if noise is likely to be a
problem, sound - absorbing insultaion should be used inside
the duct. Ductwork should be fabricated and installed in
accordance with local and national codes.

2:4.3 Piping Connections and Coolant Requirements
The following pipe connections are required:
• A drain line from the evaporator coil drain pan (This
line also serves as the drain for the optional
humidifier.)
• A water supply line to the optional humidifier (if
applicable).
• Refrigerant piping connections between the evaporator
unit and the condensing unit (air, water, or glycol). If
the evaporator unit is chilled water, connections to the
building chilled water source are required.
Drain Line
A 3/4 in. (19.1 mm) female pipe thread (FPT) connection is
provided for the evaporator coil condensate drain. This line
also drains the humidifier, if applicable. The drain line must
be located so it will not be exposed to freezing
temperatures. The drain should be the full size of the drain
connection.
The evaporator drain pan includes a float switch to prevent
operation if drain becomes blocked.
The optional condensate pump kit is required when the
evaporator is installed below the level of the gravity-fed
drain line.
CAUTION: The drain line must not be
trapped outside the unit, or water may
back -up in drain pan.
This line may contain boiling water. Use
copper or other suitable material for the
drain line.
NOTE: Remove any shipping band
from the float switch in the evaporator
pan before operating unit.
7
Humidifier Water Supply Line
Units supplied with the optional humidifier package have a
1/4 in. (6.4 mm) compression fitting with ferrule at the
water supply connection Supply pressure range is 10 PSIG
to 150 PSIG. Required flow rate is .1 gpm. A shut -off valve
should be installed in this line to isolate the humidifier for
maintenance.
Assembly Instructions:
1. Cut tube square and remove cutoff burr.
2. Slide nut then sleeve on tube, threaded end on nut
facing end of tube.
3. Insert tube into fitting seating it against stop
shoulder and thread nut to body "handtight"
4. With proper wrench tighten 1Y4 to 21/4 turns.
Caution: Overtightening can damage
fittings and/or tube causing leaks.
Chilled Water Loop —On chilled water units install manual
service shut -off valves at the supply and return lines of each
unit. These shut -off valves are used for routine service or
emergency isolation of the unit.
Chilled water supply and return lines must be insulated.
Insulating them will prevent condensation of the water
supply and return lines to the unit.
The minimum recommended water temperature is 42 °F.
Design pressure is 300 PSIG. Connection sizes are 3/4 in.
(19.1 mm) FPT for 3 ton units.
Water /Glycol Loop —Water and Glycol cooled systems
require coolant loop connections as specified in the
condensing unit installation instructions.
Refrigerant (R -22) Loop —All split systems require two
refrigerant lines (an insulated copper suction line and a
copper liquid line) between the evaporator and the
condensing unit.
Three possible methods exist for installing the copper
suction and liquid lines.
• Close coupling the units together using only the quick
connects. (See Figure 14).
• Using an optional Sweat Adapter Kit and hard piping
between the two units.
• Using optional pre - charged line sets (for 2 and 3 ton
models only).
All refrigeration piping should be installed with high
temperature brazed joints. Prevailing good refrigeration
practices should be employed for piping supports, leak
testing, evacuation, dehydration, and charging of the
•
refrigeration circuits. The refrigeration piping should be
isolated from the building by the use of vibration isolating
supports. To prevent tube damage when sealing openings in
walls and to reduce vibration transmission , use a soft
flexible material to pack around the tubes.
It is important to handle the pre - charged lines with care so
they will not get kinked or damaged. Use tube benders and
make all bends before making connections to either end.
Coil any excess tubing in a horizontal plane with the slope
of the tubing toward the condensing unit.
When installing remote condensing units above the
evaporator, the suction gas line should be trapped at the
evaporator. This trap will retain refrigerant oil in the off
cycle. When the unit starts, oil in the trap is carried up the
vertical riser and returns to the compressor.
q
NOTE: When installing remote
condensing units below the evaporator,
the suction gas line should be trapped
with an inverted trap the height of the
evaporator. This prevents refrigerant
migration to the compressor during off
cycles.

connects.
Be especially careful when connecting the.quick connect
fittings. Read through the following steps before making
the connections.
1. Remove protector caps and plugs.
2. Carefully wipe coupling seats and threaded surfaces
with a clean cloth.
3. Lubricate the male diaphragm and synthetic rubber se
with refrigerant oil.
4. Thread the coupling halves together by hand to insure
that the threads mate properly.
5. Tighten the coupling body hex nut and union nut with
the proper size wrench until the coupling bodies
"bottom out" or until a definite resistance is felt.
6. Using a marker or pen, make a line lengthwise from tl
coupling union nut to the bulkhead.
7. Tighten the nuts an additional quarter -turn, the .
misalignment of the lines shows how much the
coupling has been tightened. This final quarter -turn is
necessary to insure that the joint will not leak Refer tc
the Connection Sizes and Torque chart on the previous
page for torque requirements.

2.4.5 Electrical Connections
Each unit is shipped from the factory with internal wiring
completed. Refer to electrical schematic when making
connections. Electrical connections to be made at the
installation site are:
• Control wiring between the evaporator unit and the
condensing unit, if applicable.
• Control the wiring between the control panel (wallbox)
and the evaporator unit control board.
Power Connections
All power and control wiring and ground connections must
be in accordance with the National electrical Code and local
codes. Refer to Unit serial tag data for electrical
requirements.
Caution: Use copper wiring only.
Make sure that all connections are
tight.
Voltage supplied must agree with the voltage specified on
the unit name plate. If a field supplied disconnect switch is
required, it may be bolted to the ceiling unit, but not to any
of the removable panels. This would interfere with access to
the unit. Make sure that no refrigerant lines are punctured
when mounting the disconnect switch.
Route the electrical service conduit through the hole
provided in the cabinet and terminate it at the electric box.
Make connections at the factory terminal block or
disconnect switch, L1, L2, (L3). Connect earth ground to
lug provided. For 208 VAC applications, the low voltage
transformer tap must be changed. Refer to the electrical
schematic.
An optional single point power kit is available for units that
are installed close coupled. This kit should be mounted
inside the evaporator before installing the unit in the
ceiling. (See Figure 14)

2.5.1 Location Considerations
The centrifugal fan air cooled condensing unit may be
located above the dropped ceiling or any remote indoor
area. If noise is of concern, the condensing unit should be
located away from personnel. Normal operating sound may
be objectionable if the condensing unit is placed near quiet
work areas. The recommended maximum refrigerant line
length is 45 feet.
To mount the unit in the ceiling, refer to Section 2.4,
Installing the Ceiling Units.
2.5.2 Electrical Connections
Refer to Section 2.4.5, Electrical Connections, for general
wiring requirements and cautions. Refer to electrical
schematic when making connections.
2.5.3 Piping Connections
Details for Refrigerant (R -22) Loop piping are in Section
2.4.3, Piping Connections and Coolant Requirements.
2.5.4 Ducting
The total external static pressure for the inlet and outlet
ducts, including grille, must not exceed 0.5 inches of water.
General Considerations
Use flexible ductwork or nonflammable cloth collars to
attach ductwork to the unit and to control vibration
transmission to the building. Attach the ductwork to the unit
using the flanges provided. Locate the unit and ductwork so
that the discharge air does not short circuit to the return air
inlet.
Ductwork that runs through a conditioned space or is
exposed to areas where condensation may occur must be
insulated. Ductwork should be suspended using flexible
hangers. Ductwork should not be fastened directly to the
building structure.
For multiple unit installations, space the units so that the
hot condensing unit exhaust air is not directed toward the
air inlet of an adjacent unit.
Considerations for Specific Applications
In applications where the ceiling plenum is used as the
heat rejection domain, the discharge air must be directed
away from the condensing unit air inlet and a screen must
be added to the end of the discharge duct to protect service
personnel. Locate the air discharge a minimum of 4 feet
from an adjacent wall. Failure to do so may result in
reduced air flow and poor system performance
If the condensing unit draws air from the outside of the
building, rain hoods must be installed. Hood intake
dimensions should be the same as the condensing unit duct
dimensions. In addition, install a triple layer bird screen
over rain hood openings to eliminate the possibility of
insects, birds, water, or debris entering the unit.
Avoid directing the hot exhaust air toward adjacent doors or
windows.

2.6 OUTDOOR AIR COOLED CONDENSING UNIT
INSTALLATION
2.6.1 Location Considerations
To insure a satisfactory air supply, locate air cooled
propeller fan condensing units in an environment providing
clear air, away from loose dirt and foreign matter that may
clog the coil. Condensing units must not be located in the
vacinity of steam, hot air, or fume exhausts, or closer than
18 inches from a wall, obstruction, or adjacent unit. Avoid
areas where heavy snow will accumulate at air inlet and
discharge locations.
The condensing unit should be located for maximum
security and maintenance accessibility. Avoid ground -level
sites with public access. The recommended maximum
refrigerant line length is 45 feet.
Install a solid base, capable of supporting the weight of the
condensing unit. The base should be at least 2 inches higher
than the surrounding grade and 2 inches larger than the
dimensions of the condensing unit base. For snowy areas, a
base of sufficient height to clear snow accumulation must
be installed.

2.6.2 Piping Connections
Details for Refrigerant (R -22) Loop piping are in Section
2.9.3, Piping Connections and Coolant Requirements.
2.6.3 Electrical Connections
Refer to Section 2.4.S, Electrical Connections, for general
wiring requirements and cautions. Refer to electrical
schematic when making connections.
Power Connections
The outdoor condensing unit requires its own power source
and earth ground. with a disconnect switch (field supplied)
to isolate the unit for maintenance. A transformer is
available for 277 VAC, single phase, applications (2 and 3
ton).
Control Connections
Field- supplied control wires must be connected between the
evaporator and the condensing unit. (See Figure 7, Unit
Electrical Connections, and the electrical schematic on the
units for more details.)
Three (3) wires are required between the evaporator and
condensing unit. A fourth wire is required on systems with
hot gas bypass.

2.7 Water and Glycol Cooled Condensing Unit
2.7.1 Location Considerations
The centrifugal fan air cooled condensing unit may be
located above the dropped ceiling or any remote indoor
area. If noise is of concern, the condensing unit should be
located away from personnel. Normal operating sound may
be objectionable if the condensing unit is placed near quiet
work areas. The recommended maximum refrigerant line
length is 45 feet.
To mount the unit in the ceiling, refer to Section 2.4,
Installing the Ceiling Units.
2.7.2 Electrical Connections
Refer to Section 2.4.5, Electrical Connections, for general
wiring requirements and cautions. Refer to electrical
schematic when making connections.
Control Connections
A 3 or 4 -wire control connection is required from the
evaporator unit to the condensing unit. Glycol cooled units
also require a two-wire control connection to the
drycooler and pump package.
2.7.3 Piping Connections
Details for Refrigerant (R -22) Loop piping are in Section
2.4.3, Piping Connections and Coolant Requirements.
Water /Glycol Piping Considerations
Manual service shut -off valves should be installed at the
supply and return line to each unit. This enables routine
service and/or emergency isolation of the unit. When the
condensing unit fluid quality is poor, filters that can be
easily serviced should be placed in the supply line. These
filters extend the service life of the condensing unit.
Condensing Unit Fluid Requirements
The maximum fluid pressure is 150 PSI standard pressure
and 350 PSI for high pressure units (Refer to unit nameplate
and model number description page at beginning of this
manual). The water cooled system will operate in
conjunction with either a cooling tower or city water.
Glycol cooled systems will operate in conjunction with a
cooling tower, city water, or drycooler.
Automotive anti- freeze must not be used in glycol
systems. Prepare glycol solution using customary practices.
Regulating Valve
Water /Glycol cooled units include a coolant flow regulating
valve which is factory adjusted and should not need field
adjustment.
Standard pressure and high pressure valves are adjusted
differently. Contact Liebert Service before making any
adjustments.
