INSTALLATION

This dishwasher must be installed on a level, rigid, nonflammable surface. Ensure that the machine is level by installing
the feet (shipped in the wash tank of the machine) and adjusting the leveling. Be sure to provide adequate space for water,
drain and electrical connections.

WATERSUPPLY

A 1/2" -140°F (60°C) hot water line with 30 PSI flow pressure and shut-off valve is required. A pressure reducing valve*
may be required. A 1/2" flexible supply hose* is recommended from the shut-off valve to the water fill valve on the
dishwasher to facilitate maintenance and servicing of the machine. A 90° elbow adapter for the water inlet valve is
furnished with the machine and can be found in the wash tank with the adjustable feet. There should be sufficient hose
length to permit the machine to be pulled out for service.

DRAIN
This dishwasher is equipped with an automatic drain pump that will pump the drain water to a maximum height of 40" (1

meter). A 1" ID flexible drain hose* is recommended 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 for some applications. Drain pump
equipped machines have a white button on the control panel beside the green power button. There should be sufficient
hose length to permit the machine to be pulled out for service.

ELECTRICAL

A 208-240 volt, 60 Hz, Single Phase circuit is required for this unit.
Check the rating plate on the machine for amp draw. In spite of the
fact that the rating plate shows 208 volts, the unit is designed func tion
properly on 208 volts to 240 volts. The top & back panels must be
removed for the electrical hook-up. The terminal block is located
inside the back cover. Pass the cable through the cable strain relief and
connect the wires to the terminals LI (brown wire), L2 (blue wire) &
Ground (yellow & green wire). Replace the top & back panels being
careful not to pinch or kink any wires or hoses. There should be
sufficient cable length to permit the machine to be pulled out for
service. DO NOT TURN ON THE POWER TO THE MACHINE

UNTIL THE WATER SUPPLY & DRAIN LINES HAVE BEEN
CONNECTED

IMPORTANT NOTE
Reasonable access to and around the machine for service must be provided. Disconnecting of hard plumbing or
removal of counter tops or cabinets, etc., for servicing is not covered by warranty.
