Dishwasher With Electric Booster (Separately Connected)
Single phase machines with an electric booster require two separate connections, one for the booster
and the other for the dishwasher (including motor, controls and tank heat). For single-phase machines,
all power supply connections are made to terminal blocks (Fig. 16). The single phase dishwasher is
connected to terminal block 1TB in the controls area. The single phase booster is connected to
terminal block 2TB in the controls area.
If the machine is three phase, the electrical connection for the dishwasher is made to the contactor
2CON in the controls area. The electrical connection for the three phase booster is made to the
contactor 3CON in the controls area (Fig. 17).
Dishwasher With Electric Booster (Single Point Electrical Connection)
Three phase machines configured with the optional single point electrical connection are connected
to terminal block 1TB in the controls area (Fig. 18). The machine must be grounded according to
electrical code(s); a grounding lug is provided.

EQUIPMENT 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 THE ELECTRICAL POWER TO THE MACHINE (BOTH DISHWASHER AND
BOOSTER IF APPLICABLE) AND FOLLOW LOCKOUT / TAGOUT PROCEDURES.
Vent Fan Control
The vent fan control feature is standard on all machines. The vent fan control relay provides switch
contacts only and does not provide power to the vent fan motor. The rating for a vent fan control relay
connected to terminals VFC1 and VFC2 is 1.5 Amps at 240 Volts maximum. When the dishwasher is
connected to the vent fan, the vent fan is switched on when the dishwasher is on, and off when the
dishwasher is off.
Remote Booster Control
The booster control feature is standard on all machines. The load rating for remote booster control
connections to BSTR1 and BSTR2 is 0.1 Amp. at 120 Volts maximum. The booster control provides
a control signal only and does not provide power to the remote booster. When a remote booster
is connected to the dishwasher, the booster is on when the dishwasher is on and off when the
dishwasher is off.
