An aluminum mesh 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 via the  
remote mounted control panel. The aluminum mesh  
mist eliminator prevents wash water from entering  
the safety filter and carbon panel sections of the unit.  
The safety bag filter is intended to protect the carbon  
panel section if power is lost to the ionizer collector  
cell.

Power Play’s PLC control is preprogrammed to  
manually initiate and cycle through the wash, rinse,  
dry and system standby steps, as described below.  
To initiate a wash manually, with the system in the  
NORMAL mode, depress the WASH push-button.  
The WASH mode consists of 6 steps. FIGURE 6  
describes the indicating light and system component  
status while operating in the WASH mode. After the  
WASH/FAN DRY cycle is completed, the system is  
programmed to shut down and manual start next  
morning. As indicated in FIGURE 6, there is a 5 minute  
delay period, after wash initiation, before the wash  
process begins. If the WASH cycle is accidentally  
initiated, the operator may reset the system during  
the 5 minute delay period, and the system will return  
to NORMAL operation. If the system is reset after  
the 5 minute delay period, the WASH cycle will be  
accelerated and the system will return to the NORMAL  
mode after the WASH cycle is complete.

On rare occasions, it may be necessary to reset  
the system. This may be required if a WASH cycle  
is inadvertently initiated. As indicated previously in  
FIGURE 6, there is a 5 minute delay period after the  
WASH button is pushed, before the wash process  
begins. If the WASH cycle is accidentally initiated, the  
operator may reset the system during the 5 minute  
delay period, and the system will return to NORMAL  
operation. If the system is reset after the 5 minute  
delay period, the WASH cycle will be accelerated and  
the system will return to the NORMAL mode after the  
WASH cycle is complete.

Maintenance  
Routine service is required in order to ensure optimum  
performance and reliability of the system.  
Normal  
Wash Delay

RESET  
A. Aluminum Mesh Pre-filters & Post Filters: These  
metal filters in the precipitator should be removed  
and thoroughly cleaned on a minimum two (2)  
week interval, removing any grease and particulate  
buildup.  
B. 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. The cells should be removed and  
manually cleaned every 6 months minimum.  
RESET  
Soak  
Rinse  
C. Safety Bag Filters: Safety filters change out  
frequency depends on the volume of cooking.  
Change filters every 3 months or prior to an  
increase in resistance that affects hood capture  
efficiency. See ordering instructions in this manual.

Detergent Dispenser  
General: The detergent dispenser supplies detergent  
to the wash system during the WASH mode. The  
detergent dispenser is designed to operate for  
the entire duration of the WASH mode (2 minutes),  
and the amount of detergent delivered is regulated  
by the flow control valve. The detergent reservoir  
holds approximately 55 gallons of detergent. The  
DETERGENT LOW light will illuminate when the  
amount of detergent in the reservoir drops below eight  
(8) gallons. The reservoir should be refilled as soon as  
possible after the DETERGENT LOW light comes on,  
to ensure that detergent is dispensed and to prevent  
pump damage.  
Airflow  
Figure 8  
NOTE  
The detergent pump motor will not operate while the  
detergent low light is illuminated.  
D. Activated Carbon Panels: Carbon panel change  
out frequency is also dependent on the volume  
of cooking. Replace when an increase in odor  
breakthrough is first noticed. Change out should  
range between 3 and 6 months.  
Adjustments  
The liquid level sensor was setup during field  
inspection and should not require adjustment.  
E. System Fan/Motor: Fan, motor and drives should  
be inspected, serviced and cleaned according to  
the manufacturer’s instructions, annually.  
Flow Control Valve Adjustment  
The detergent dispenser will be adjusted during  
commissioning to a detergent-to-wash water ratio  
of 1:20, meaning one gallon of detergent is used  
for every 20 gallons of wash water used. In some  
applications, the amount of detergent used may  
need to be increased. This may be done by adjusting  
the flow control valve on the upper left front of the  
detergent dispenser.  
F. Wash System Detergent: Greenheck specifies  
GLT-33 detergent, manufactured by Green Ladder  
Technologies. This detergent has been specially  
formulated for this type equipment, and will  
help ensure successful operation and optimum  
performance. GLT-33 should also be used to  
manually clean mesh filters and ionizing-collecting  
cells. Substituting other types of detergent may  
result in decreased system performance, system  
shutdown or voided limited warranty. See detergent  
ordering instruction sheet in this manual.  
Adjustments to the flow control setting should be  
done in small increments over a period of several  
wash cycles. Turning the knob clockwise, increases  
the amount of detergent used during a wash cycle.

To access the pre- and post-mesh filters and ionizing  
collecting cells, follow these instructions.  
1. Rotate the disconnect knob on the upper right  
hand corner of the System Control to the OFF  
position. “Lock Out” the system by flipping the red  
lever in the handle outward and securing it with a  
padlock.  
2. Open the access door by turning the knob on the  
red safety switch until the plunger is fully retracted,  
then unscrew the black knobs to unlatch the door.  
3. Slide the metal mesh filters from the tracks  
4. Thoroughly clean the metal mesh filters using hot  
water and a GLT-33 detergent.  
5. Reinstall the filters in the tracks.  
6. Remove the collector cells retaining brackets using  
a 7/16-inch wrench.  
7. Remove the red and blue high voltage cables and  
jumper cables by firmly grasping the red boots and  
pulling them from the high voltage plugs.  
8. Carefully remove a cell from the cabinet. Each 2 ft.  
cell weighs approximately 65 lbs., so use caution  
when handling. Use care not to bend or dent the  
collecting plates or framework.  
9. Carefully inspect the cell for bent collector plates.  
Bent plates may be carefully straightened by hand,  
using needle-nose pliers.  
10. Inspect the cell for residual grease that was not  
removed during the wash process. Excessive  
grease buildup indicates that the cells need to be  
removed from the cabinet and thoroughly cleaned  
manually, following the procedures under Ionizing-  
Collecting Cells in Maintenance.  
11. Reinstall the cell to the location from which it was  
removed. The serrated ionizing blades of the cell  
must be facing upstream. There is an airflow arrow  
on the cell end plate.  
12. Reconnect the high voltage cables, and cell  
retaining brackets.  
13. Close the access door completely, engage the  
door latch, and turn the knob on the red safety  
switch until the plunger is fully extended.
