Electrical Connections
General Information
Wiring connections must be made exactly as shown in the wiring diagram found on the inside of
the heat pump access panel; see the wiring diagrams on pages 31-33.
The UltraTemp
TM
Heat Pump must include a definite means of grounding and bonding. There is a
ground lug inside the heat pump electrical compartment.
Equipotential Bonding
The Wiring Rules (AS/NZS 3000) and most other codes require in many circumstances that me-
tallic components of a pool structure, including reinforcing steel, metal fittings, and above ground
equipment be bonded together with a solid copper conductor. The heat pump contains a metal (ti-
tanium) heat exchanger which is in contact with the pool water, which may need to be connected to
this bonding grid. A bonding lug is provided to ensure this requirement can be met. Please refer to
the Wiring Rules (AS/NZS 3000) and any local codes for details on whether equipotential bonding is
required.
Main Power
Electrical wiring to the heat pump must be in accordance with the latest edition of the Wiring Rules
(AS/NZS 3000). All wiring must be done by a certified or qualified electrician.
The following is the procedure to wire the heat pump to the electrical source:
Be sure the power to the circuit for the heat pump is turned off.
1. Remove the front panel of the heat pump cabinet (you need to loosen the front screws on the top
panel aswell).
2. Remove the service panel to the heat pump electrical compartment.
3. Electrical supply lines must be run through watertight conduit on the front panel. Run the wires
and conduit from the power source and connect them to the conduit connection. Use suitable
gauge connection wire as per below table.
4. Connect the power leads to the terminals in the electrical compartment as shown in the wiring
diagram.
5. Verify that all other wires are secure, they may have loosened during shipment.
6. Connect the ground wire to the ground lug provided.
7. Replace the service panel and reinstall screws to hold it in place.
8. Replace the front panel.
