FEEDER PUMPS FOR OPERATION
The JPX-300H/HC/HN dishmachines are supplied with integral detergent and rinse aid chemical feeder pumps. The JPX-300L
dishmachine is supplied with integral detergent, rinse additive and sanitizer 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 concentration 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 prime switches located at the top of the unit to prime each pump. The switches are clearly marked (“D”, “R”, and
“S”) as to what chemical feeder pump they are assigned to.
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 the detergent cam 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 the rinse cam 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
depending on the concentration and type of sanitizer used. It is adjusted by changing sanitizer cam 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 protective gear when handling these chemicals. If you do come in contact with these chemi-
cals, immediately flush the affected area with fresh water.
