POTENTIOMETER ADJUSTMENT (continued):
WARNING:
When working on the dishwasher, disconnect the electrical service and place a red tag
at the disconnect switch to indicate work is being done on that circuit.
Refer to Section 2.9, Chemical Connections, pages 16-21, and to Potentiometer Adjustment,
Steps 1-8, pages 66-67, before proceeding with the instructions below.
DETERGENT, RINSE AID, AND SANITIZER POTENTIOMETER ADJUSTMENT:
The UH-200B, UH-200, UH-100B, UH-100 model dishwashers utilize optional detergent
and/or rinse aid chemical dispensing pumps.
The UL-100 model comes standard with detergent, rinse aid, and sanitizer pumps.
NOTE:
Chemical adjustments require testing equipment to accurately determine the proper
type and concentration of commercial dishwashing chemicals. This is best performed
by a qualified chemical supplier.
DETERGENT ADJUSTMENT:
Detergent is injected in the first 30 seconds of the automatic cycle. Turn the Detergent POT CW
to increase the pump run time, CCW to decrease the pump run time. The minimum setting for
the detergent pump is 1 second. The pump is locked out after the fill/rinse valve closes.
RINSE AID AND SANITIZER ADJUSTMENT:
Only the UL-100 low temperature machine contains rinse aid and sanitizer pumps as standard
equipment. Models UH-200B, UH-200, UH-100B, UH-100 may have the optional rinse aid
pump installed.
• If you want more rinse aid or sanitizer dispensed during the final rinse, turn
the POT adjustment CW. This makes the pump activate earlier in the cycle from the
moment the fill/rinse valve closes.
• Turn the POT CCW to make the pump activate less time from the moment the fill/rinse
valve closes.
ADJUSTMENT EXPLANATION
Refer to Fig. 7.3.4, next page.
The illustration shows the fill/rinse valve and dispensing pump(s) portion of the automatic cycle
for each model. The example given shows one possible setting; the actual setting may vary.
• Notice that the zero reference point for the pump run time setting is the moment that
the fill/rinse valve closes.
• Rinse aid and sanitizer pumps never run AFTER the fill/rinse valve closes during the
final rinse portion of the automatic cycle.
