**WATER SUPPLY**
A 3/4” NPT fitting is required with 30 psi. dynamic
pressure. A water pressure regulator* may be required.
The water flow pressure cannot be less than 30 psi or
exceed 30 psi. If the water pressure exceeds the
prescribed amount, you will get inconsistent washing
temperature, premature failure and thus may void the
warranty.
Incoming water temperature must be 140º F (60º C). An
easily accessible shut-off valve is recommended,
making installation, service and maintenance easier.
A flexible drain hose is provided to make installation,
servicing and maintenance easier. Make sure that the
water is free from calcium and hard water deposits. For
these situations, an inline water cartridge system is
highly recommended. Build-up of calcium and lime
deposits in the washer may occur and servicing will be
required on a more frequent basis which will not be
covered by the warranty.
**DRAIN**
This dishwasher is equipped with an automatic drain
pump that will pump the drain water to a maximum
height of 36" (0.9 meter). A 1" ID flexible drain hose is
supplied to facilitate maintenance and servicing of the
machine. It is important not to reduce the size of this
hose. A 1" check-valve* may be required. Drain pump
equipped machines have a white button on the control
panel beside the green power button.

ELECTRICAL
A 208-240 volt, 60 Hz, Single Phase circuit is required for
this unit. Check the rating plate on the front of the machine
for the amp draw. In spite of the fact that the rating plate
shows 208 volts, the unit is designed function properly on
208 volts to 240 volts.
The top & back panels must be removed for the electrical
hook -up. The top panel is secured by two Phillips head
screws. Once the screws are removed, the panel should be
slid to the back and lifted. The back panel is also held by
two screws. Remove them, pull the bottom away from the
machine and lift the panel. G
The terminal block is located inside the back cover. Pass
the cable through the cable strain relief and connect the

CHEMICAL PUMPS
The model 737E is supplied with factory installed liquid detergent
and rinse additive pumps to automatically dispense during each
wash & rinse cycle. Before accessing the bottom
section of the dishwasher, make sure that the power is
turned off at the source (breaker panel).
The bottom panel can only be removed with a flat tool
like a screwdriver.
Insert the screw-driver in the gap between the front
panel and the side panel. Pry open towards you.
Do this on both sides.
The red & blue hoses connected to the pumps must be routed out
of the bottom of the dishwasher. The red tube is for detergent and
the blue tube is for rinse additive. The containers can be either to
the right or left of the dishwasher. Perforating the stainless panel
is not recommended. The two chemical pumps are factory
adjusted to accommodate most installations.
There is a mark on the pump indicating this setting.
It is recommended that only qualified personnel alter these
settings.
UNDER NO CIRCUMSTANCES should the detergent pump be
turned off.

VISUAL CHEMICAL DELIVERY VERIFICATION
The peristaltic chemical pumps are located in the base of the dishwasher. They
feature a transparent cylinder (1) to visually see if fluid is passing through the
pumps. The pumps are automatically energized during the “initial fill” (when
turning on the dishwasher) and “rinse cycle” (after the wash cycle). During this
time, the flow indicator (2) will move between the “Min Flow” position and the
“Max Flow” position (3) in the cylinder. It is normal for the pumps to cycle on and
off.
If the flow indicator (2) does not move during the fill or rinse, no fluid is
circulating through the pump. It is recommended not to use the dishwasher until
this condition is resolved.

TROUBLESHOOTING
1. Ensure that there is sufficient chemical in the container and that the tube is not kinked. The filter
on the end of the tube must reach to the bottom of the container. If the filter or tube is blocked,
remove and soak in warm water to dislodge the obstruction.
2. There may be air in the pump. To “Prime” the pumps (remove the air), turn off and drain the
dishwasher. Replace the drain tube, close the door and turn on the dishwasher. The pumps will be
activated as the machine fills. The Flow Indicators (2) should start to move by the time the machine
has filled. If not, repeat the drain and fill.
3. The Squeeze Tube (flexible tube inside the pump) is worn or perforated. This part is a normal wear
and tear item that must be replaced periodically (when pump performance diminishes). Call for
Service.
4. The pump does not operate - the roller in the middle of the pump does not turn during the fill or
rinse. Call for Service.

IMPORTANT: Remember to always use caution and protective gear whenever you are manipulating
chemicals. They can burn the skin. Follow the manufacturer’s instructions carefully.
