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.

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.

Reset Mode
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.

FIGURE 7 on page 10 illustrates the sequence of
events that occurs when the system is reset during
the different stages of system operation. When the
system is in the RESET mode, the white RESET light
will illuminate on the control panel. It is recommended
that the system be programmed so that system on/
off and wash cycles are automatically initiated. This
programming will be done by the factory engineer
during commissioning.

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

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.

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.

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.
