Receiving
Upon receiving the product, check to make sure all items are accounted for by
referencing items shown on the packing list. Inspect each crate for shipping
damage before accepting delivery. Notify the carrier if any damage is noticed.
The carrier will make a notation on the delivery receipt acknowledging any
damage to the product. All damage should be noted on all the copies of the
bill of lading which is countersigned by the delivering carrier. A Carrier
Inspection Report should be filled out by the carrier upon arrival and filed
with the Traffic Department. If damaged upon arrival, file claim with carrier.
Any physical damage to the unit after acceptance is not the responsibility of
manufacturer.
Unpacking
Verify that all required parts and the correct quantity of each item have been
received. If any items are missing, report shortages to your local
representative to arrange for obtaining missing parts. Sometimes it is not
possible that all items for the unit be shipped together due to availability
of transportation and truck space. Confirmation of shipment(s) must be limited
to only items on the packing list. Remove all other shipping/ packing
materials including fan tie down straps.
Handling
Units are to be rigged and moved by the lifting brackets provided or by the
skid when a forklift is used. Location of brackets varies by model and size.
Handle in such a manner as to keep from scratching or chipping the coating.
Damaged finish may reduce ability of unit to resist corrosion.
Storage
Units are protected against damage during shipment. If the unit cannot be
installed and operated immediately, precautions need to be taken to prevent
deterioration of the unit during storage. The user assumes responsibility of
the unit and accessories while in storage. The manufacturer will not be
responsible for damage during storage. These suggestions are provided solely
as a convenience to the user.
INDOOR
The ideal environment for the storage of units and accessories is indoors,
above grade, in a low humidity atmosphere which is sealed to prevent the entry
of blowing dust, rain, or snow. Temperatures should be evenly maintained
between 30°F (-1°C) and 110°F (43°C) (wide temperature swings may cause
condensation and “sweating” of metal parts). All accessories (including the
main control panel and the keypad/touchscreen user interface) must be stored
indoors in a clean, dry atmosphere.
Remove any accumulations of dirt, water, ice, or snow and wipe dry before
moving to indoor storage. To avoid “sweating” of metal parts, allow cold parts
to reach room temperature. To dry parts and packages use a portable electric
heater to get rid of any moisture build up. Leave coverings loose to permit
air circulation and to allow for periodic inspection.
OUTDOOR
Units designed for outdoor applications may be stored outdoors, if absolutely
necessary. Roads or aisles for portable cranes and hauling equipment are
needed.
The unit should be placed on a level surface to prevent water from leaking
into it. The unit should be elevated on an adequate number of wooden blocks so
that it is above water and snow levels and has enough blocking to prevent it
from settling into soft ground. Locate parts far enough apart to permit air
circulation, sunlight, and space for periodic inspection. To minimize water
accumulation, place all unit parts on blocking supports so that rain water
will run off.
Do not cover parts with plastic film or tarps as these cause condensation of
moisture from the air passing through heating and cooling cycles.
NOTE
The main electrical panel, if stored, shall be stored indoors only in a dry
environment protected from the elements.
Inspection & Maintenance during Storage
While in storage, inspect equipment once per month. Keep a record of
inspection and maintenance performed.
If moisture or dirt accumulations are found on parts, the source should be
located and eliminated. At each inspection, rotate the fan wheel by hand ten
to fifteen revolutions to distribute lubricant on motor. Every three months,
the fan motor should be energized. If paint deterioration begins,
consideration should be given to touch-up or repainting. Fans with special
coatings may require special techniques for touch-up or repair.
Machined parts coated with rust preventive should be restored to good
condition promptly if signs of rust occur. Immediately remove the original
rust preventive coating with petroleum solvent and clean with lintfree cloths.
Polish any remaining rust from surface with crocus cloth or fine emery paper
and oil. Do not destroy the continuity of the surfaces. Wipe thoroughly clean
with Tectyl® 506 (Ashland Inc.) or the equivalent. For hard to reach internal
surfaces or for occasional use, consider using Tectyl® 511M Rust Preventive or
WD-40® or the equivalent.
Removing from Storage
As units are removed from storage to be installed in their final location,
they should be protected and maintained in a similar fashion, until the
equipment goes into operation. Prior to installing the unit and system
components, inspect the unit assembly to make sure it is in working order.
1. Check all fasteners, set screws on the fan, wheel, bearings, drive, motor
base, and accessories for tightness.
2. Rotate the fan wheel(s), where applicable, by hand and assure no parts are
rubbing.

Grease Trapper ESP System Function
Grease Trapper ESP is an electrostatic precipitator pollution control unit
(PCU), with an additional carbon filtration module designed for two specific
functions:
· Remove smoke/grease particles from kitchen exhaust
· Remove odor from kitchen exhaust
NOTE
· Grease Trapper ESP must be connected to a listed exhaust hood assembly and
must be installed in accordance with local building codes, NFPA 96 and NEC.
· The unit must be installed with a minimum 12 inch clearance to combustible
materials on top of unit and six inches on the sides and bottom.
A mechanical impingement pre-filter removes large airborne particles from the
incoming airstream prior to reaching the ionizer cell. The permanent
electrostatic collector section removes grease and smoke particles from the
airstream using a high voltage ionizer cell(s). The ionizer imparts a positive
charge on the grease and smoke particles as they pass. These particles are
then repelled by positively charged plates and collected on negatively charged
plates. Upon completion of each cooking day, a wash sequence is initiated for
the self-cleaning function of the electrostatic cell and impingement modules
via the control panel. The mesh mist eliminator filter prevents wash water
from entering the carbon filtration section(s) of the unit.
NOTE
Do not use this unit for applications with high concentrations of water vapor,
or other matter, that is highly conductive if condensed in the airstream.
Heavy water vapor can cause continuous electrical shorting within the ESP
cells, which does not allow the unit to collect cooking particulate and
perform as designed.
There are two configuration options for the Grease Trapper ESP PCU’s. The
standard unit will have two ESP modules and one carbon filtration section for
use with light, medium and heavy duty cooking. For solid fuel applications
which will contain a greater quantity of grease, smoke and odors, the solid
fuel unit should be selected. The solid fuel unit will contain three ESP
modules and two carbon filtration modules.
NOTE
This unit should NOT be installed in applications where incoming airstream at
the inlet of the unit is capable of exceeding 130°F.
NOTE
Grease Trapper ESP is designed to remove submicron, airborne particulate
generated from cooking processes. This system is NOT INTENDED to eliminate
regular hood and ductwork cleaning and service. Improper care and maintenance
of this system and associated hoods and ductwork may present a fire hazard.

System Components
NOTE
The installation criteria for each of the system components shown below should
be considered when selecting a site for install. For further detail on
installing the components, refer to the INSTALLATION section on page 7.
Unit Body
The unit body is shipped on a mounting rails ready for installation. If the
unit was ordered with an exhaust fan, typically the fan will also be mounted
on the same set of rails as part of the PCU assembly. Unless specified and
built for outdoor use, the PCU must be mounted indoors and be protected from
weather. The unit should be easily accessible for service personnel. (1) One-
inch water supply line and (1) two-inch waste water drain line is required at
the unit for the system’s wash function.
Power packs (power supply boxes) are attached to hinged cell access doors of
the cabinet assembly which are wired directly back to the main control panel
via the quick connect plug and play cables. By default these will be factory
wired when the main control panel is mounted on the rails. The high voltage
from the power packs is wired directly to the cells through a spark plug style
cable passing through the unit via UL listed compression seals. Power supplies
are self-protecting against overloads (which can be caused by contaminant
build up that leads to short circuits in ionizer and collector sections) and
are self-regulating from AC input voltage variations from 108 – 264 VAC.
ESP Cells
ESP cells will ship in separate crate to protect them during shipping. Cell
quantities for each stage are based on unit size.
Cells have an ionizer section and collector section. Ionizer section includes
spiked ionizer plates that are charged with 12,000 VDC. Collector section
includes alternating plates between ground (0 VDC) and 6,000 VDC potential.
Cells are fed voltage through high voltage spark plug-style cables that are
insulated from the unit housing. These pins contact brass plungers located on
the side of the cell near the bottom.
Universal Unit Cell
If a module has multiple cells, power is passed from cell to cell through
these brass plungers coming into contact with the pins on next cell.
The total current to both the ionizer section and collector section is below 6
mA.
Impingement Filters / Mist Eliminator Filters / Carbon Trays
Impingement filters and mist eliminator filters will ship installed in the
unit. Carbon trays will ship in a separate container. Filter quantities for
each stage are based on unit size.
Each carbon filter is a 20 x 20 x 2 inch, 12 lbs., and contains coconut shell
carbon, standard. Max designed velocity across each filter is 90 ft/min.

Ductwork Connections
Ductwork must conform to IMC and SMACNA guidelines.
All factory-built grease duct needs to be constructed in accordance with
ANSI/UL 1978 and should be manufactured and installed in accordance with their
listing.
All field-built grease ductwork must be constructed in the following manner
per NFPA 96, unless otherwise specified by the local authority having
jurisdiction (AHJ):
Materials – Ducts shall be constructed of and supported by carbon steel not
less than 1.37 mm (0.054 in.) (No. 16 MSG) in thickness or stainless steel not
less than 1.09 mm (0.043 in.) (No. 18 MSG) in thickness.
Installation – All seams, joints, penetrations, and ductto-hood collar
connections shall have a liquid-tight external weld.
Units intended for indoor mounting have an outlet mounting flange provided on
the outlet of the fan. Outlet ductwork from the exhaust fan is required to be
per the above mentioned methods unless otherwise specified by the local
authority having jurisdiction (AHJ).
NOTE
Ductwork should be properly insulated to prevent formation of condensation
through temperature change. Condensation that occurs in ductwork will short
circuit ionizing-collecting cells.
Cells and Carbon Trays
Open ESP cell and carbon tray access doors by turning and releasing all
latches on the door.
Insert cells into the ESP module(s) in the units, making sure the airflow
arrow stamped on each cell is pointing towards the fan. ESP cells should be
pushed in by the next one in the row. For example, the second cell pushes the
first cell, the third cell pushes the second, etc. The last cell installed
should be no more than 4 inches (+/-1/8 inch) from the edge of the cell to the
edge of the frame.
After inserting the last cell in a row, install the two (2) cell pushers to
secure the cells, these pushers should be hanging from the above rack. Insert
the cell pusher between the cell and the vertical c-channel of the cell rack,
hooking the end of the pusher around the c-channel. Locate the pusher low
enough on the c-channel that the attached wire is taut. Then, fasten the bolt
until it’s tight against the face of the cell. Repeat for each cell pusher on
each row.
Insert carbon trays into the carbon module(s) in the unit. Make sure trays are
inserted where gasketing material is orientated on the left and right hand
side, NOT the top and bottom, so there is a seal against the filter next to
them.
After all cells and filters are properly installed, re-latch unit doors by
closing the door and turning the handlatches until secured.

Initial System Start-Up
1. Verify unit is installed properly and all field water and electrical
connections have been made.
2. Check that all ESP cells have been installed properly. There is a
directional arrow that indicates the direction of the proper airflow. If cells
are not installed in the proper direction, the unit will not operate
correctly.
3. Close and properly fasten the doors on the unit to ensure the door limit
switches are closed.
4. Turn on electrical power to control cabinet and exhaust fan.
5. Turn on fan disconnect.
6. Turn on the disconnect switch on the PCU terminal enclosures to energize
the power packs.
7. Press the fan button on the user interface to start the fan. Some
electrical arcing (audible snapping and cracking) is normal at initial power
up as leftover debris in the duct and unit may occasionally get caught inside
the cells. Arcing should subside after a short period of time. If arcing
continues, reference page 35 for troubleshooting assistance.
8. Check for alarms on the system controller. Correct any alarms that may be
displayed (See page 14 for details).
9. System should now be ready for operation.
10. Turn on water supply.
11. Prime the detergent pump. On the CAREL controller, navigate to Service >
Wash Settings > “Prime Detergent Pump” menu screen. Changing “OFF” to “ON”
will start the detergent pump. Monitor the detergent line and press the ESC
key once the detergent reaches the hot water line. This will stop the
detergent pump.
NOTE
As a safety precaution, the system will only operate in the NORMAL mode when
the access doors of the unit are completely closed and the terminal box
disconnect switch is in the ON position.
If the plunger of the safety switch on all of the doors is not fully
depressed, the red FAULT light on the main controller (PLC) will illuminate
and the unit will not start. Do not attempt to operate the unit with the
access doors open or bypass the safety.
Sequence of Operation
The operation of the Grease Trapper ESP system falls into two main categories:
1. NORMAL: System collects smoke and grease particulate from the airstream.
The unit can be started by pressing the fan button on the user interface or by
closing the remote run contact (terminals RE-1A and RE-1B). The remote run
command is a contact that can be wired to the kitchen control panel,
timeclock, or any other contact closure desired to call for the system to run.
NOTE
BOTH the keypad fan button needs to be disengaged AND the remote run contact
needs to be open in order for the fan to shut off. A call for the fan to run
will not allow for a wash to start, which will prevent the cells from being
cleaned.
During normal operation, as the grease enters the unit, it will pass through
an impingement filter that is designed to remove the large grease particles.
After passing through the impingement filter, it will enter the ESP module(s)
which will remove the grease particles and smoke from the airstream through a
process of electrostatic precipitation. Upon leaving the ESP modules, the air
then passes through a mist eliminator filter which stops water from entering
the carbon filters during the wash down process and also helps protect the
carbon filter section from grease build-up. The air then enters the carbon
filtration section which removes the odors from the airstream.

Grease Trapper ESPTM Kitchen Exhaust Pollution Control System 11
®
Sequence of Operation – continued
2. WASH: System goes through cycles to clean and dry dirty ionizing-
collecting cells
The wash cycle is recommended to be performed daily on the unit and uses an
automated wash down sequence to remove the grease that has been collected on
the impingement filters and ESP cells. The length of time and frequency of
washing will be determined by the grease load in the airstream. The times
shown are the factory settings but can be adjusted as needed based on site
conditions.
The wash cycle can be started three different ways:
1. User presses the wash button on the keypad or touch screen.
2. An external wash contact is closed (terminals WS-1A and WS-1B).
3. The controller can be set up to wash the unit automatically based on a
schedule set up on the controller.
The wash sequence will wash each impingement and ESP module using the steps
below. For units with multiple ESP modules, the wash sequence will repeat
itself for each module with the exception of the drip dry and fan dry
sequence. The drip dry and fan dry portion will start once all of the modules
have completed washing and are used to dry the entire unit before placing it
back into service. An optional, up to 2-hour delay between each module’s wash
sequence can be set on the controller to allow water heaters or grease
interceptors time to recover between wash sequences can be set on the
controller to allow water heaters or grease interceptors time to recover.
Wash Override: The wash sequence can be stopped by pressing the wash button on
the user interface. This will cancel the wash sequence and return the PCU to
normal operation. When calling for a wash or during the wash sequence if the
fan is turned on either by the fan button, remote fan enable contact, or the
fire system is activated the wash sequence will stop and the exhaust fan will
turn on.

Resetting the VFD Faults
Upon a VFD fault, first determine the cause of the fault and correct. Typically, if the drive detects a fault, it will remain inoperable until that fault has been corrected and the drive has been reset.
Once a fault has been corrected, the easiest way to clear the displayed fault on the VFD is to shut off power to the drive from the power source (breaker). Wait for the VFD to fully discharge and then restore the power.
Upon correcting a minor fault, recycling power may not be necessary. Simply press RESET , then press

Maintenance
NOTE
Maintenance frequency will vary based on site conditions. Adjust frequency as
needed.
NOTE
It is recommended to visually inspect the cells at least once a week for the
first month of the unit operation. Increase or decrease the wash times based
on how clean the cells are upon inspection.
Routine service is required in order to ensure optimum performance and
reliability of the system.
Impingement and Mist Eliminator Filters: These metal filters should be
inspected for grease and particulate build-up on a monthly basis. This monthly
inspection should be done after the system has competed a wash cycle. If
grease or particulate build-up is apparent, remove filters and clean manually.
Ionizing-Collecting Cells: The ionizing-collecting cells should be inspected
for grease build-up on a monthly basis. This monthly inspection should be done
after the system has completed a wash cycle. If grease build-up is apparent,
remove cells and clean manually. After opening the module door, release the
(2) cell pushers, and use the cell removal tool to hook onto the handle of the
ESP cell and remove from module. The cells should be removed and manually
cleaned every 6 months minimum.
Carbon Trays: Carbon tray changeout frequency is dependent on volume of
cooking. Replace when an increase in odor breakthrough is first noticed.
Change out should range between 3 and 6 months for typical cooking
applications. Change out may be more frequent for heavy grease applications.
If opting to refill carbon trays instead of replacing them, follow the below
steps:
1. Locate and remove fastener on 2-inch prefilled carbon tray.
2. Slide the filter tray top out of the filter.
3. Remove the old charcoal, and replace.
4. Replace tray top and fastener.
System Fan/Motor: Fan, motor and drives should be inspected, serviced and
cleaned according to the manufacturer’s instructions, annually.
Wash System Detergent: Manufacturer recommends Zep X701 detergent,
manufactured by Zep Incorporated. This detergent has been specifically
formulated for this type of equipment, and will help ensure successful
operation and optimum performance. In normal applications, the X701 cleaning
solution can be diluted at a 1:1 ratio of chemical to water. Upon inspection
of the cells, if it appears they are not being fully cleaned during the wash
cycle, it is recommended the detergent add timer be increased, the detergent
flow control valve adjusted, or the detergent strength increased. Zep X701
should also be used to manually clean the impingement and mist eliminator
filters. Substituting other types of detergent may result in decreased system
performance, system shut down and voiding of the unit warranty.
To access the impingement and mist eliminator filters and ESP cells, follow
these instructions.
1. Turn fan off using keypad.
2. Turn all power pack mounted disconnect switches to off. Follow all
applicable lock and tag-out procedures to safely “Lock Out” the system to
avoid potential injury.
3. Unlatch all fasteners on the door to open the access door to filters.
4. Short the cells to ground, using the shaft of an insulated screwdriver, to
ensure any residual charge is removed before handling the cells.
5. Slide the metal mesh filters from the tracks.
6. Thoroughly clean the metal mesh filters using hot water and a Zep X701
detergent solution.
7. Reinstall the filters in the tracks.
8. Unlatch the door fasteners to access the ESP cells.
9. Loosen and unhook the (2) cell pushers from the ESP cell.
10. Carefully remove cells from the module. Each cell weighs approximately 35
lbs.; use caution when handling. Use care not to bend or dent the collecting
plates or framework.
11. Carefully inspect the cell for bent collector plates. Bent plates may be
carefully straightened by hand, using needle-nose pliers.
12. Inspect the cell for residual grease that was not removed during the wash
process. Excessive grease buildup indicates that wash times may need to be
increased on the units. For excessive buildup the cells may need to be removed
from the cabinet and manually cleaned.
30 Grease Trapper ESPTM Kitchen Exhaust Pollution Control System ®
13. Reinstall the cell to the location from which it was removed. There is an
airflow arrow on the cell end plate. Re-insert the cell pushers by hooking the
pusher between the cell and the c-channel of the cell rack and tighten until
the cable is taught or the cell is fastened.
14. Close the access door completely to ensure the door limit switches are
closed and install the door fasteners.

Troubleshooting
Problem: Cells shorting immediately (Green indicator light continually flashes)
Cells are dirty/clogged
Run through a wash, making sure detergent level is full. If cells are still dirty, safely removing cells and manual cleaning/spraying may be necessary. If air compressor is available on site, spray out cells thoroughly of any dust and debris.
Cells are not installed correctly
Safely remove cells and make sure they are installed correctly, ensure the cell pushers are installed tightly with no slack in the cable. Cable could short out on collector ionizer rods to the ground if installed incorrectly, see page 7.
Cell wiring incorrect
IONIZER should be connected to the RED spark plug cable (Ionizer is the spiked smaller plates that face the inlet of the unit) COLLECTOR should be connected to the BLUE spark plug cable. GROUND cable should be connected to the BLACK spark plug cable. Cells have been labeled by the laser to indicate each spark plug connection.
Dry portion of wash cycle was bypassed
If the unit dry portion of the wash cycle was bypassed, the cells may still be wet. Run the fan for 60 90 minutes to dry out the cells.
Problem: When running unit, green indicator on terminal enclosure illuminates, then after a few seconds turns off, then repeats
Power supply is not providing correct voltage Possible faulty or incorrectly programmed power supply. Contact factory for
back to control panel
further troubleshooting assistance.
Problem: Indicator lights (LEDs) on terminal enclosures not illuminating
Wiring not matching polarity of LEDs
Switch the leads on the LEDs located on the cover of the terminal enclosure(s).
Faulty LEDs or faulty power supply
Test voltage to LEDs and to input power of power supply when unit is on. Replace LEDs/power supply if faulty.
Problem: Power supplies operating (green), but cells don’t appear to be collecting contaminants
Insufficient connection between cells or plugs
Ensure spark plug style cables are properly connected, and that the cell pusher is properly installed.
Problem: Cells not fully clean after completed wash cycle
Detergent empty
Check to see if there is a low detergent alarm, refill detergent if empty
Incorrect detergent used
Make sure detergent used is the recommended Zep X701
Wash sequences are too short for cooking duty
Increase wash sequence times
Water temperature or pressure incorrect
Make sure water temperature is 140°F and 40 psi
Problem: Wash cycle won’t start via button, digital input, nor the wash scheduler
Fans are running
Fans need to be turned off before wash can be started
System in fire mode
Check for fire micro-switch wiring (normally-closed contact between C1 and NC1).
Wash cycle is starting, but water isn’t turned Confirm wash is running by referencing keypad/touchscreen. Check hot water
on to unit
shut off valves feeding the unit.
Problem: Unit not washing
Something is preventing the wash from occurring
Review wash history pages on controller, see page 17-18 for more details.
