SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS
CHEMICAL DISPENSING EQUIPMENT HT-1 & HT-2
TO PREPARE PUMPS FOR OPERATION
The HT-1 is a chemical dispensing unit supplied with a detergent pump. Locate the open end of the chemical tube with the tube
stiffener and place in the appropriate container.
The HT-2 is a chemical dispensing unit supplied with detergent and rinse additive pumps. Locate the open ends of the chem-
ical tubes with the tube stiffeners and place each one in the appropriate container.
A. Red Tubing = Detergent
B. Blue Tubing (HT-2 Only) = Rinse Aid
PRIMING CHEMICAL FEEDER PUMPS
Chemical feeder pumps need priming when the machine is first installed or if for some reason the chemical lines have been
removed and air has been allowed to enter.
CAUTION: Water must be in the sump and wash tank prior to the dispensing of the chemical.
1. Verify that the chemical tube stiffener inlet is in the detergent container.
2. Use the toggle switches on the front of the dispenser box to prime each pump. There is one (1) switch mounted above each
peristaltic pump. One will prime the detergent pump, and the second will prime the rinse aid pump (HT-2 Only).
3. To prime the pump, hold the switch in the momentary position until chemical can be observed entering the tub.
4. Detergent is dispensed as required during the wash cycle by the cam timer. The amount of detergent may need to be
increased or decreased depending on water quality and type of detergent. It is adjusted by changing Cam 6 on the cam timer.
5. Rinse additive is dispensed as required into the final rinse. The amount of rinse aid may need to be adjusted depending on
water hardness and results. It can be changed by changing Cam 5 on the cam timer.
WARNING: Some of the chemicals used in dishwashing may cause chemical burns if they come on contact with
your skin. Wear appropriate protective gear when handling these chemicals. If you do come in contact with
these chemicals flush the area with fresh water.
