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 apparant, 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.

Grease Trapper ESP™ Kitchen Exhaust Pollution Control System
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 build-
up the cells may need to be removed from the
cabinet and manually cleaned.
