e. No valve of any type to be installed between the relief valve and tank or in the

drain line.

6. A shock absorber is recom

mended in the hot

water outlet line to soften the water

ham

mer caused by automa

tic dishwasher solenoid valves.

7. Install the in-line pressure and tem

perat

ure gauge, when supplied, in the entering

cold/warm water line. If supplied, install the optional second dial temperature and

pressure gauge in the outlet line. The tem

per

ature sensing element must be in the hot

water stream

and the gauge must be m

ounted upright.

FILLING THE HEATER

1. Open the valve to the cold/warm water inlet and allow the heater and piping system to

com

pletely fill, as indicated by a steady fl

ow of water through the dishwasher rinse

nozzles.

NOTE

: Flush the tank at full flow for 10 m

inutes prior to putting into service.

ELECTRICAL INSTALLATION

1. Enter the base through the factory cut KO’s with properly sized feeder leads, See

Wiring Chart. Single-phase installations require two (2) leads. All Hubbell 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. Connect incoming ground wire to ground lug supplied.

4. Check for proper grounding. Check for AC millivolts (mV) between the ground

connection at the booster and the inlet piping past the optional dielectric union (on the

building side, not the booster side). There should be zero potential/millivolts (mV). If

not zero, then the piping should be re-grounded.

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

connections are necessary.

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

OPTIONAL XB1 EXPANSION BOARD (used for temperature alarm / interlock)

1. If desired, the XB1 can be used as an alarm relay or a temperature interlock at a

setpoint other than the water tem

erature setpoint on the booster heater.

2. If the XB1 is not factory installed, m

ount th

e XB1 to the control panel and connect the

XB1 to the T1000 control board with the factory supplied cable between JX4 on the

XB1 and J1 and J4 on the T1000 and connect the ground between JX6 on the XB1

and J8 on the T1000.

3. Make connections as required to the relay term

inal block. When the temp

erature drops

below the XB1 setpoint the relay is open between N

ormally Open (NO) and Common
