Electrical Connections and Wiring

RISK OF ELECTRICAL SHOCK OR ELECTROCUTION.
This heat pump contains wiring that carries high voltage. Contact with these wires could result in death or serious injury to pool
or spa users, installers, or others due to electrical shock, and may also cause damage to property. Always disconnect power
circuit before connecting the heat pump.
Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify
proper operation after servicing.

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 10-11.
The UltraTemp Heat Pump must include a definite
®
means of grounding and bonding. There is a ground
lug inside the heat pump electrical compartment and a
bonding lug on the left side of the heat pump.
Bonding
The National Electrical Code and most other codes
require that all metallic components of a pool
structure, including reinforcing steel, metal fittings,
and above ground equipment be bonded together with
a solid copper conductor not smaller than 8 AWG.
For Canada, a 6 AWG or larger solid copper bonding
conductor is required.. The heat pump, along with
pumps and other pool equipment must be connected
to this bonding grid. A bonding lug is provided on the
left side of the heat pump to ensure this requirement is
met.
This heater must be connected to a bonding grid
with a solid copper wire not smaller in diameter
than 8 ga. For Canadian installations a solid copper wire not smaller in
diameter than 6 ga should be used.

Main Power

Electrical wiring to the heat pump must be in
accordance with the latest edition of the National
Electric Code (NEC), ANSI/National Fire Protection
Association (NFPA) 70 in the United States, and in
Canada, the Canadian Electrical Code (CEC) C22.1,
unless local code requirements indicate otherwise.
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 left panel of the heat pump
cabinet, (you do not need to remove the star-head
screw at the top left corner).
2. Remove the service panel to the heat pump
electrical compartment. (Front left corner of unit)
3. Electrical supply lines must be run through
watertight conduit. Run the wires and conduit from
the power source and connect them to the conduit
connection on the left side of the heat pump.
4. Connect the power leads to the bottom terminals
on the main compressor contactor as shown in the
wiring diagram.
5. Verify that all other contactor wires are secure,
they may have loosened during shipment.
6. Connect the ground wire to the ground lug
provided on the bottom of the electrical
compartment.
7. Replace the service panel and reinstall screws to
hold it in place.
8. Replace the front left panel.
9. Connect a copper bonding wire (8 AWG) (6 AWG
in Canada) to the bonding lug on the left side of
the heat pump.
