INSTALLATION

This glasswasher 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" - HOT (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 glasswasher is equipped with an automatic drain pump that will pump the drain water to a maximum height of 36" (0.9

meter). Drain pump equipped machines have a white button on the control panel beside the green power button. 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* is required on drain pump equipped models. 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 function
properly on 208 volts to 240 volts. The terminal block is located at the

back, base of the machine. Open the cover, pass the cable through the
cable strain relief and connect the wires to the LI, L2 & Ground.
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.

removal of counter tops or cabinets, etc.. for servicing is not covered by warranty.
