DETERGENT PUMP:
For proper operation of the detergent pump and wash system, hot water pressure must be between 40 PSI
(min.) and 60 PSI (max.). The water temperature range is 140°F to 180°F.
Water pressure, water temperature, grease accumulation, wash cycle length, wash cycle frequency, and the
type and amount of detergent used can influence cleaning effectiveness. In very heavy cooking operations,
additional washes may be necessary. The wash time can also be increased to a maximum of 10 minutes; the
wash time is factory set at four minutes. Consult Fig. 23A to change the wash time. If this is not effective,
manual cleaning may be necessary (hand scrubbing, steam cleaning or pressure washing).
Adjusting Detergent Pump Output Rate
Adjustment of the detergent flow may be necessary. Pump must be
OFF.
Use the following formula to determine proper pump setting: (Adjust pump setting as needed for proper
cleaning.)
0.3 oz./min. x Hood Length = Pump Setting The minimum pump setting is #2.
To calculate the number of washes a full detergent
tank will deliver for a specific application, use these
formulas:
1) Pump setting (oz. per min.) x Wash Length (4.0 min. std.)
= Oz. per wash
2) 320 oz. Tank Capacity = Number of Washes per Tank

Adjust the Detergent Injectors Output:
1) With the pump and detergent injector off
hold adjustment knob(1) and loosen
wing nut.
2) Turn adjustment knob until the pointer
(3) indicates the desired setting. Six is
the maximum; zero is the minimum.
3) While still holding adjustment knob,
tighten wing nut.
