ELECTRICAL CONNECTIONS

WARNING: ELECTRICAL AND GROUNDING CONNECTIONS MUST COMPLY WITH THE APPLICABLE PORTIONS OF THE NATIONAL ELECTRICAL CODE AND/OR OTHER LOCAL ELECTRICAL CODES.

WARNING: DISCONNECT ELECTRICAL POWER SUPPLY AND PLACE A TAG AT THE DISCONNECT SWITCH TO INDICATE THAT YOU ARE WORKING ON THE CIRCUIT.

Dishwasher

Refer to the wiring diagram attached inside the control box and to the machine data plate for service size requirements when connecting the dishwasher. Also, refer to Electrical Data, page 12.

The dishwasher electrical service connection can be made through the 11/8" diameter hole for 3/4 inch trade size conduit located at the bottom of the right side of the control box. By removing a knockout, this hole can be enlarged to 13/4" diameter for 1 inch trade size conduit.

A fused disconnect switch or circuit breaker (not supplied) must be installed in the electrical service line supplying this dishwasher and should meet the requirements of your local electrical code.

All power supply connections are made at the terminal block 1TB in the control box. The machine must be grounded according to electrical code(s); a grounding lug is provided in the control box.

Check Rotation (Three-Phase Machines Only)

Three-phase motors must rotate in the direction of the arrow on the pump housing. In order to check rotation, observe the motor fan through the end bell. Close the machine doors and press the power switch to ON. When the machine is completely filled, place the cycle switch (located on the side of the control box) on MANUAL and place the WASH / RINSE switch (located under the cycle switch) on WASH. The motor fan must rotate in the direction of the arrow on the pump housing.

If the rotation is incorrect, DISCONNECT ELECTRICAL POWER SUPPLY and interchange any two of the incoming power supply leads. Reconnect the power supply and verify correct rotation.

Electric Booster Water Heater

The Electric Booster electrical connection is separate from the dishwasher electrical connection.

Refer to Electrical Data, page 11. Before making electrical connection, test the electrical service to assure that it agrees with the specifications on the Electric Booster portion of the data plate. Also, refer to the wiring diagram attached inside the cover of the control box.

A fused disconnect switch or circuit breaker must be installed in the electrical service line supplying this booster and should meet the requirements of your local electrical code.

The electric booster service connection is made through the 13/4" hole for 1 inch trade size conduit located at the bottom of the control box. If the booster is three phase, the electrical connection is made to the contactor 3CON in the control box. If the booster is single phase, the electrical connection is made to the terminal block 4TB in the control box. The machine must be grounded according to electrical code(s); a grounding lug is provided in the control box.
