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.

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 parts 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. This type hose is standard for most warewashing machines. Fittings should be available from your local hardware or plumbing supply house. Flexible hoses must be used 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 has a gravity drain. Maximum height of the drain should not exceed 20" (50cm). A 1.5" ID flexible drain hose is recommended to facilitate maintenance and servicing of the machine.

Electrical:

A 208-240 volt, 60 Hz, Single Phase or Three Phase circuit is required for this unit. Check the rating plate on the machine for amp draw. Pump rotation must be verified on 3 phase units at time of install. In spite of the fact that the rating plate shows 208 volts, the unit is designed function properly from 208 volts to 240 volts. The bottom cover (under the controls) is snapped in to position and should be removed. The terminal block is located in the base of the unit, on the left side. Pass the cable through the cable strain relief at the back and connect the wires to the terminals L1 (brown wire), L2 (blue wire), L3 (black wire) & Ground (yellow & green wire). There should be sufficient cable length to permit the machine to be pulled out for service.

DO NOT manually fill wash tank with water. The dishwasher will fill automatically when the power is turned ON.

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. Verify rotation of the pumps for three phase unit.

All panels must be replaced on the unit when the installation is completed.
