10 Grease Grabber™ Power Play Kitchen Exhaust Pollution Control System
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.
Adjustments
The liquid level sensor was setup during field
inspection and should not require adjustment.
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.
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.
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.
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.
E. System Fan/Motor: Fan, motor and drives should
be inspected, serviced and cleaned according to
the manufacturer’s instructions, annually.
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.
