the booster heater contactor energizes. The illustration below shows how the booster heater contactor is
wired. The booster heater contactor is located behind the lower front access panel.

Interlock Circuit Operation

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

UH200B, UH200, UH170B, UH170, UH100B, UH100, UL100

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.

6. For the Model UL100, the hot water supply must provide a minimum of 140°F/60°C, measured
at the dishwasher.

7. A water hardness of 3 grains/gal (US) [51.3 mg/L] or less is recommended.

Installation

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.

5.25% sodium hypochlorite (chlorine beach) must be used as a sanitizing agent to provide a

minimum concentration of 50 ppm in the final rinse. The 50 ppm concentration must be checked

Rinse Sentry Mode

As previously stated, the nal rinse water temperature must be a minimum 180-195ºF/82-91ºC during the

final rinse cycle to ensure that all wares are sanitized. If for any reason, the hot water temperature in the
booster tank cannot provide this temperature, then the dishwasher will enter a Rinse Sentry Mode of
operation.

The Rinse Sentry changes the Normal Operation Mode as described below:

1. The Rinse Sentry constantly monitors the water temperature inside nal rinse booster.

2. If the temperature inside the booster heater falls below 180-195ºF/82-91ºC then the Rinse Sentry
will extend the wash cycle time until the booster heater water temperature reaches the proper
temperature.

3. The in-cycle light will remain illuminated during the Rinse Sentry Mode.

4. The dishwasher will continue to wash for a maximum time of 5 minutes.

5. After 5 minutes the Rinse Sentry will stop and the dishwasher cycle will resume
normal operation.

6. The RINSE water temperature digital display must be monitored to ensure that a minimum of
180-195ºF/82-91ºC is maintained. If the temperature is below the required minimum, then the

problem must be identied and corrected immediately to maintain sanitization.

Extended Wash Mode

The Extended Wash Mode is used to wash heavily soiled items such as pots, pans and other wares that
require more washing time than the standard 70 second Normal Wash Mode. The dishwasher will remain
in the Extended Wash Mode until the operator exits the mode.

1. Load a dish rack into the dishwasher, close the door fully and press the START button.

2. The green in-cycle light will illuminate and the dishwasher will begin a normal wash cycle.

3. Wait 10 seconds for the detergent to enter the wash compartment.

4. Press the EXT WASH button to place the dishwasher in the Extended Wash Mode.

5. The green extended wash light will illuminate indicating that the machine is in the
Extended Wash Mode.

6. The dishwasher will continue to wash for a maximum of 15 minutes unless the operator
presses the EXT WASH button again.

7. Press the EXT WASH button. The green extended wash light will go out indicating that
the dishwasher has returned to the Normal Wash Mode.
