ELECTRICAL CONNECTIONS — DISHWASHER
WARNING: ELECTRICAL AND GROUNDING CONNECTIONS MUST COMPLY WITH THE
APPLICABLE PORTIONS OF THE NATIONAL ELECTRICAL CODE ANSI / NFPA 70 (LATEST
EDITION) AND/OR OTHER LOCAL ELECTRICAL CODES.
WARNING: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AND FOLLOW
LOCKOUT / TAGOUT PROCEDURES. THERE MAY BE MULTIPLE CIRCUITS. BE SURE ALL
CIRCUITS ARE DISCONNECTED.
Some machines may have more than one electrical power supply. All supplies MUST be disconnected.
Motor(s)
Connect a permanent electrical power supply to the terminal block in the control box. Three-phase
motor(s) must rotate the impeller in the direction of the arrow found on the pump housing of the motor
pump unit (Fig. 10), the drive motor can rotate in either direction. Before placing the machine into
service, a check must be made to verify correct rotation. Only one motor needs to be checked, as the
machine is wired at the time of manufacture so that all motors will rotate the same direction.
Fig. 10
If the impeller does not rotate in the direction of the arrow, DISCONNECT POWER SUPPLY(IES) to
the machine and interchange any two power supply leads at the control box terminal block. On
machines with a circuit breaker box, reverse any two leads at the incoming power supply block in the
circuit breaker box (three-phase only). Start the machine momentarily and verify proper direction of
rotation.
Electric Heat
Connect a permanent electrical power supply to the line terminals of the control box. The tank water
temperature is regulated by a solid-state thermostat which is preset at the factory and should not
require adjustment. If an adjustment is necessary or the machine is to operate low temperature, contact
your local Hobart service office. Use the machine thermometers for verification of proper water
temperatures.
