DANGER—SHOCK HAZARD: Make sure electrical power to the heater is disconnected to avoid potential serious injury or damage to components.

CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.

NOTE: Minimum 18 AWG, 105°C, stranded wire must be used for all low voltage (less than 30 volts) external connections to the unit. Solid conductors should not be used because they can cause excessive tension on contact points. Install conduit as appropriate. All high voltage wires must be the same size (105°C, stranded wire) as the ones on the unit or larger.

Installer action is required to electrically enable your Hi Delta heater to operate after making the power con- nections. You must make a connection on Terminal Block #3 for temperature control connections. This will be done based on the controller option selected with your heater order.

1.For Pool and Closed Loop Water Source Heat Pump applications, your heater should be config- ured to operate in an ON/OFF firing mode. This means that you will connect a single-pole control to stage one of stage selector (Terminals 4 & 5). Then jumper the remaining firing stages. For example, if your heater is a 162, you will jumper stage two. Then your heater will either be on at full fire, or it will be off.

2.For multi-stage controller connections, connect each stage of the control to the corresponding stage selector terminal block in the heater. Stage 1 of the heater to stage 1 of the control. Stage 2 of the heater to stage 2 of the control, and so on. Set the operating control at the setpoint in which you want the heater to maintain. Ensure that the sens- ing bulb of the control is at the point in the system that will best maintain the temperature you want. For example, when you are heating a tank of water, you want the operating control sensor bulb in the tank.

Consult the wiring diagram shipped with the heater in the instruction packet. The Stage 1 connections are for the remote tank control through the heaters 24 volt transformer. DO NOT attach line voltage to the Stage 1 connection. Before starting heater, check to ensure proper voltage to heater and pump.
