7.Install the dial temperature and pressure gauge in the outlet line. The temperature sensing element must be in the hot water stream and the gauge must be mounted upright.

FILLING THE HEATER

1.Open the valve to the cold water inlet and allow the heater and piping system to completely fill, as indicated by a steady flow of water through the dishwasher rinse nozzles.

NOTE: Flush the tank at full flow for 10 minutes prior to putting into service.

ELECTRICAL INSTALLATION

1.Enter the base through the factory punched KO’s with properly sized feeder leads, See Wiring Chart. Single-phase installations require two (2) leads. All 3-phase heaters are intended for use with a 3- wire delta system plus ground. No neutral is required. For a 4-wire plus ground system, install 3 legs of power plus the ground and terminate the neutral leg.

2.Install these power leads into the box lugs on the power distribution block or magnetic contactor, as required.

3.All other electrical connections are made at the factory; therefore, no other electrical connections are necessary.

4.Connect incoming ground wire to ground lug supplied.

5.Check all connections, including factory connections, for tightness.

OPTIONAL XB1 LOW TEMPERATURE INTERLOCK

1.If desired, the XB1 can be used as an alarm relay or a temperature interlock at a setpoint other than the water temperature setpoint on the booster heater.

2.If the XB1 is not factory installed, mount the XB1 to the control panel, plug the P65 probe into the XB1, and plug the XB1 into the T1000 control board.

3.To set the XB1 setpoint, turn the potentiometer clockwise for a higher setpoint and counter- clockwise for a lower setpoint. The range is adjustable between 150°F and 180°F.
