StorinFilteri'm Operation and Maintenance
Overview
The StormFilterTm (CBSF) consists of a multi-chamber steel, concrete, or plastic catch
basin unit that can contain up to four StormFilter cartridges. The steel CBSF is offered
both as a standard and as a deep unit. The CBSF is installed flush with the finished
grade and is applicable for both constrained lot and retrofit applications. It can also be
fitted with an inlet pipe for roof leaders or similar applications. The CBSF unit treats
peak water quality design flows up to 0.13 cfs, coupled with an internal weir overflow
capacity of 1.0 cfs for the standard unit, and 1.8 cfs for the deep steel and concrete
units. Plastic units have an internal weir overflow capacity of 0.5 cfs.
Maintenance Guidelines
Maintenance procedures for typical catch basins can be applied to the StorniFilter
(CBSF). The filter cartridges contained in the CBSF are easily removed and replaced
during maintenance activities according to the following guidelines.
1. Establish a safe working area as per typical catch basin service activity.
2. Remove steel grate and diamond plate cover (weight 100 lbs, each).
3. Turn cartridge(s) counter -clock -wise to disconnect from pipe manifold.
4. Remove 4" center cap from cartridge and replace with lifting cap.
5, Remove cartridge(s) from catch basin by hand or with vactor truck boom.
6. Remove sediment via vactor truck (min,clearance 13" x 24").
7. Remove sediment from cartridge bay. (min. clearance 9.25" x 11 ").
& Rinse interior of both bays and vactor remaining water and sediment.
9. Install fresh cartridge(s) threading clockwise to pipe manifold.
10. Replace cover and grate.
I I. Return original cartridges to Contech for cleaning.

Olt LIFT-OUTSYSTEM
In many effluent and sewage basins or lift stations it is
advisable to install rile pump on a guide rail system or on
a lift -out adapter to facilitate installation and removal for
inspection and/or service. Most codes (to not allow person -
net to enter 4vetvvell without the correct protective equip-
ment and training, (;tilde rails arc designed to allow easy
removal of the pump without the need for entry into the
wetwell or need to disturb piping. The guide rail or lift -
out adapter should locate the purnp opposite drc, influent
opening preventing stagnate areas where solids can settle.

PIPING
Discharge piping should be no smaller than the hump
discharge diameter and kept as short as possible, avoiding
UnneCOSSaty fittings to raininnZe friction toSSCS
Install an adequately sized check valve matched to the
solids handling capability of the pump to prevent fluid
backflow. Backflow can allow the punip to spin back-
wards and may cause premature seal, hearing, shaft wear.
If the pump is turning backwards when it is called on to
.start the increased torque may cause damage to the pump
motor and/or motor shaft.
Instill an adequately sized giec valve AFTER the check
valve for, ponip, plumbing and check valve maintenance,
Important — Before pump installation. Drill a vi�11
(4.8nun) relief hole in the discharge pipe. It should be
located within the wetweil, 2" (Sham) turn) above the purrip
discharge but below the clieck valve. The relief [role al-
lows any air to escape from the casing. Allowing liquid
into the casing will insure that tire pump can start when
the liquid level tises. Unless a relief hole is provided, a
bottom intake PLIMP could "air lock" and will not pump
water even though the impeller turns.
All piping must be adequately supported, so as riot to
impart air)- piping strain or loads on the pump.
The pit access cover must be of sufficient size to allow for
inspection, maintenaricc and crane or hoist service,

FLOAT SWITCHTYPES
There are two basic float switch designs; single-action
and wide-angle. Single-action switches operate over 1
range of 15" so they open and close quickly. Wide-angle
floats operate over a 90° swing with the tether length be-
tween the float body and the pivot point controlling the
On -Off range. The design determines how many floats
are required with different systems or controls,
Floats may be normally open (NO) for pump down
applications or to empty a tank. Normally closed (NC)
switches are used to pump tip or to fill a uu&
A single-action control switch may be used only with a
control panel, never direct connected to pump.
The wide-angle, PUMP d0VVn SWitChICS may be used its
direct connected punipswirches or as control switches.
sETTINGTHE FLOAT SWITCHES
There are no absolute rules for where to set the float
switches, it varies from job to job,
Suggested Rules to Follow;
All floats should be set below the later pipe!
Off Float. Best. set so free hanging the water level is
always above the top of the pump (inotor done). Next
Best. set so the water level is not more than 6" below the
top of the pump.
On Float: set so the volinue of water between the On and
Off floats allows purrips of I th HP and under to operate
for I Inirlitne ininirrann. 'Two (2) HP and larger pumps
should run a meninuun of 2 nuturtes. Basin technical
brochure states the gallons of storage per inch of basin
height,
Lag/Alarm Float(s); should be staggered above the Off
and On floats. Try to use most of the available storage
provided by the basin, save some space for reserve stor-
age capacity. Exact reserve may be called out by local
codes, See Diergrains and Charts in, I'loat Sivitch Chart
Section,
PANEL WIRING DIAGRAMS
Our control panels are shipped with instructions and wir-
ing diagrams. Use those instructions in cranunction with
this IOM. Electrical installation should be performed
only by qualified technicians. Any problem or quotions
pertaining to another brand control must be referred to
that control supplier at manufacturer.
ALARMS
We recommend the installation of an alarm on all Waste-
water pump installations. Many standard control panels
come equipped with alarm circuits. If a control panel is
not used, a stand alone high liquid level alarm is avail-
able. The alarm alerts the owner of a high liquid level
in the liasin so they can contact the appropriate service
personnel to investigate the Situation.

Heat sensor will have an extra lead front the motor with
two conductors. These leads will be Black and White and
should be connected to the seat failure terminals in I panel
supplied with this option. If a sea] failure circuit and Fleat

lead with four conductors. For these leads the connection
for seat failure will be Black and Green and the 1 -feat sensor
will be Red and White. The model I GD/12GDS can be or-
dered with all optional seat failure circuit, but most dual seat

These units come with a single lead for power and controls.
The conductor will comae with 7 leads (previous to January
2013). Leads For seal failure and hear sensor will be Orange
and Blue. Since these units use a different style sensor in the
pump as well as a different option in the panel the connec-
tions require only two leads. After January 2013 the lead
colors on the pumps were changed to two (2) white leads
for the seal failure and hear sensor.
Be careful to choose the correct options in the Panel selec-
tion for each style pump, Ahvays follow wiring schematic
of the panel. Failure to wire the sea[ failure and heat sensor
leads correctly may prevent file pump from running or
cause musance tripping.

few seconds to check impeller rotation. It is
easier to check rotation before installing the pump. Switch
any two polver leads to reverse rotation.
Lower the purnp(s) into tire wetwell.
Check to insure that the floats will operate freely and not
contact the piping.

Once the piping connections are made and checked you can
run file PUMPS.
Piggyback Switch Operation — Plug the piggyback switch
into a dedicated grounded outlet and Eliot plug the pump
into tire switch. Test the pump by filling the wctwcfl until
the purnp goes On. If the pumps run but fail to PUMP, they
are probably air locked, drill the relief holes per the instruc-
tions in the piping Section.
Check the operating range to insure a IllininlUill one minute
run little and that the pump goes Off in the correct position.
Control Panel Operation — Fill the wctwell with clear water.

If the current unbalance is more than 2%, current read-
ings should be checked on each leg using each of the
three possible hook-ups. Roil the motor leads across the
starter in the sanie direction to prevent motor reversal.

C, Pick the imp value which is, furthest from the average
current {either high or low).
D. Determine the difference betwcen this artip value
(furthest from average) and the average,
E. Divide the difference by the average. Multiply the
result by 100 to determine percent of unbalance.
Current unbalance should not exceed 51,6 atservice
