TO PREPARE PUMPS FOR OPERATION
The PA-1/PA-2 dishmachines are supplied with detergent, rinse additive and sanitizer dispensing chemical feeder pumps.
Locate the open ends of the chemical tubes with the tube stiffeners and place each one in the appropriate container.
A. Red Tubing = Detergent
B. Blue Tubing = Rinse Aid
C. White Tubing = Sanitizer
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 is allowed to enter.
CAUTION: Water must be in the sump and wash tank prior to the dispensing of chemicals. Sanitizer in con-
centration is caustic and may cause damage without dilution.
1. Verify that the proper chemical tube stiffener inlet is in the proper container.
2. Use the toggle switches on the right side of control box to prime each pump. There are two (2) switches mounted by the
chemical feeder pumps. One will prime the sanitizer pump only, and the second will prime either the detergent or rinse aid
pump, depending upon which way it is depressed.
3. To prime the pumps, hold the switch in the momentary position until chemical can be observed entering the sump.
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 7 on the cam timer.
6. Sanitizer either chlorine or iodine is dispensed into the final rinse. The amount of sanitizer may need to be adjusted depend-
ing on the concentration and type of sanitizer used. It is adjusted by changing Cam 5 on the cam timer.
Warning: Some of the chemicals used in dishwashing may cause chemical burns if they come in 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.
