Priming the Chemical Injectors and Approximate Chemical Settings
Each chemical injector can be adjusted using its prime button and concentration adjusting screw.
These controls are located on the right side of the control box located in the lower compartment of the
glasswasher. The white injector rotors are visible through the control box window.
ALL OF THE CHEMICAL SETTINGS BELOW ARE APPROXIMATIONS.
CONSULT A QUALIFIED CHEMICAL REPRESENTATIVE TRAINED IN THE USE OF THE TEST
EQUIPMENT REQUIRED FOR TAKING SAMPLES AND PERFORMING ADJUSTMENTS.
1. Priming the Pumps:
Make sure the proper chemical pick-up tube is in its supply container, then push and hold the prime button
until the detergent, sanitizer and rinse-aid feed tubes are full of chemical. Release the Prime button.
2. Approximate Chemical Settings:
The approximate chemical volume dispensed by the chemical injectors can be
determined by counting the number of revolutions of the injector rotor.
Detergent - 1 revolution in 1-second of the detergent pump rotor ~ 0.35% concentration.
Sanitizer - 1 revolution in 5-seconds ~ 12.5 ppm of Iodophor or 50 ppm of chlorine.
Rinse-aid - 1 revolution in 8-seconds ~ the median volume recommended.
Turn the Injector Concentration screws clockwise to increase or counter-clockwise
to decrease the volume of dispensed chemical.
3. The detergent chemical setting must be performed when the hot-water ll solenoid valve is open.
The hot-water valve is open when the power switch is in the ON position during initial ll and when
the detergent tank oat assembly calls for hot water
The sanitizer and the rinse-aid setting can be performed whenever the cold-water ll solenoid valve
is open. The cold-water ll valve is open whenever the glasswasher power switch is ON and the conveyor
is turning. A separate rinse-aid is not needed when Iodophor is used as a sanitizer. Turn the Injector
Concentration Screw fully counter-clockwise until the rinse-aid injector rotor stops turning.
