Interlock Circuit Operation
Contactor
1. The dishwasher lls with water when the main power switch on the dishwasher is turned on. The booster heater thermostat calls for heat which energizes the booster heater contactor.
2. The auxiliary contact on the top of the contactor opens and removes power from the wash tank heater.
3. When the booster heater thermostat is satised, the booster heater contactor de- energizes and the auxiliary contacts close applying power to the wash tank heater.

NOTE
Plumbing connections must comply with national, local plumbing and sanitary codes.
IMPORTANT
Make sure that the flexible water supply and drain hoses are not kinked.
UH200B, UH170B and UH100B
1. All models have a 6 ft. exible hot water ll hose with a 3/4" female garden hose connector.
2. A 1/2" or larger main incoming supply line should be installed to the dishwasher.
3. A 1/2" or larger shut-off valve should be installed in the water supply line as close to the dishwasher for service.
4. For UH200B/UH170B only, a pressure regulating valve, PRV, (supplied by others) must be installed after the shut-off service valve if the incoming ow pressure exceeds 20-22 psi/138-152 kPa.
5. The hot water supply must provide a minimum of 140°F/60°C, measured at the dishwasher for the 40°F/ 22°C rise booster. For the 70°F/39°C rise booster the hot water supply must provide a minimum of 110°F/43°C measured at the dishwasher.
6. A water hardness of 3 grains/gal (US) [51.3 mg/L] or less is recommended.
UH170, UH100, and UL100
1. All models have a 6ft exible hot water ll hose with a 3/4" female garden hose connector.
2. A 1/2" or larger main incoming supply line should be installed to the dishwasher.
3. A 1/2" or larger shut-off valve should be installed in the main water supply as close to the dishwasher as possible for service.
4. All models have a built-in ow control. The incoming hot water supply pressure must be between 25-95 psi/173-655 kPa.
5. For Models UH170, and UH100, the hot water supply must provide a minimum of 140°F/60°C, measured at the dishwasher for The incoming hot water supply line must be a 1/2" or larger.

Drain Connections
UH200B, UH200, UH170B, UH170, UH100B, UH100, UL100
ATTENTION
Do not connect the drain hose to a disposer. The dishwasher will not drain correctly.
NOTE
The dishwasher drains in 8 seconds and drain water exits the hose with considerable force.
1. All models have a 6ft. 5/8" I.D. drain hose. The maximum drain height connection must not exceed 3 ft.[0.9 m].
2. The drain hose is located at the rear of the dishwasher. A 5/8" hose-barb tting is strapped to the drain hose to the hose drain piping.
3. The drain hose is secured to the rear of the machine by a clamp to maintain a goose-neck bend in the drain hose.
DO NOT REMOVE THE DRAIN HOSE RETAINING CLAMP. DO NOT STRETCH THE DRAIN HOSE.
4. Install the drain hose to a "WYE" drain tting. Connection to a "TEE" tting will prevent the dishwasher from draining completely.
5. The maximum drain ow is 15 US gpm.
6. Make sure the drain hose does not kink. Kinks will prevent the dishwasher
from draining completely, and the dishwasher will overow out the front door.
The dishwasher flexible drain hose
must be connected to a WYE fitting.
Do not connect the dishwasher
flexible drain hose to a TEE fitting.

Chemical Dispensing Pump Speed and Tank Fill Adjustments
NOTE: The chemical dispensing pump speeds are not set at the factory. Variations in the type of chemicals supplied by the chemical supplier usually require that the supplier make nal adjustments for the products supplied.
1. Adjustment screws are provided for the dispensing pumps and for the wash tank ll. They are located on the right-side of the dishwasher behind the lower front access panel.
2. Make sure the chemical containers are full and the pick-up tubes are in the proper containers.
3. Turn the dishwasher power switch ON. The switch will illuminate and the dishwasher
will ll with water.
4. Run a normal dishwasher cycle and test detergent and rinse-aid concentrations according to the chemical supplier's instructions.
CAUTION: Excessive pressure to the potentiometers when adjusting can result in bent or broken adjusting screws.
5. Each dispensing pump has a clearly marked adjustment screw. Turn the screw CW to increase the time of the dispensing pump and CCW to reduce the dispensing pump time.
6. The Fill adjustment screw will provide a small change in the tank water level. If a large adjustment is needed, then check the incoming water pressure make that the ll hose is not kinked. If the above items are okay then the size of the incoming water supply should be evaluated.
7. NOTE: For Models UH200B, UH200, UH170B, UH170, UH100B and UH100 use detergent and rinse-aid only, a sanitizer is not required.
8. For Model UL100, detergent, rinse-aid and sanitizer are used.

De-liming
Minerals accumulate on the interior surfaces of the dishwasher. The deposits have a white haze and, in cases of heavy accumulation, may appear as a granular solid. The generic name for mineral deposits is lime. The removal of lime deposits is called de-liming.
dishwasher should be de-limed regularly; how often will depend on the mineral content of your water. Inspect your machine interior for lime deposits. If de-liming is required, a de-liming agent should be
used for best results in accordance with the chemical supplier's instructions.
Danger:
Death or serious injury may result when de-liming solution is mixed with sodium hypochlorite (chlorine bleach) sanitizing agent. Mixing may cause hazardous gases to form. De-liming solution and other acids must never be mixed with chlorine, iodine, bromine, or fluorine.
Your
Caution:
Skin contact with de-liming solutions can cause severe irritation and possible chemical burns. Always wear protective clothing when handling chemicals.
Attention:
Contact your chemical supplier for specific safety procedures and instructions for the use of the de-liming solution supplied for the dishwasher. De-liming solution or other chemicals are not supplied by the dishwasher manufacturer.
