Section 4. Electrical Connections
4.1
General Information
Wiring connections must be made exactly as shown
in the wiring diagram found on the inside of the heat
pump access compartment (see Figure 8 for single
phase electrical wiring). The heat pump must include
a definite means of grounding and bonding. There is a
bonding lug on the right side of the heat pump, where a
bond wire must be attached.
4.2
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 (CSA
®
C22.1),
unless local code requirements indicate otherwise.
The heat pumps come factory-wired intended for use
with 230 VAC, 60 Hz single phase. See the rating plate
for the electrical specifications. All wiring must be done
by a certified electrician.
The following is the procedure to wire the Jandy JRT
heat pump to the electrical source specified on the
Rating Plate:
1. Be sure the power to the circuit for the heat pump
is turned off.
2. Remove the three (3) screws that attach the
service/access panel to the heat pump unit (see
Figure 9).
3. Remove the front panel.
4. Remove the screw on the right side of the control
box.
5. Open the control box.
6. Run the electrical conduit through the base of the
unit.
7. Connect the electrical conduit to the right-side of
the control box with the conduit connector.
8. Connect the wires to the terminals on the main
contactor as shown in the wiring diagram. See
Figure 8.
9. Connect the ground wire to the ground lug
provided in the electrical compartment.
10. Close the control box and secure with the provided
screw.
11. Reseat the service access panel and secure with the
provided screws.
12. Connect a copper bonding wire (8 AWG). In
Canada, it shall be not smaller than 6 AWG
(13.3 mm
2
) to the bonding lug on the right side of
the heat pump.
WARNING
ELECTRICAL SHOCK HAZARD.
This heat
pump contains wiring that carries high voltage.
Contact with these wires may result in severe
injury or death. Disconnect power circuit before
connecting the heat pump
CAUTION
Label all wires prior to disconnection when
servicing controls. Wiring errors can cause
improper and dangerous operation. Verify proper
operation after servicing.
WARNING
Follow all applicable installation codes. Prior to
Installation or performing any service, turn off all
switches and the main breaker in the pool/spa
pump electrical circuit. Failure to comply may
cause a shock or hazard resulting in severe
personal injury or death.
While disconnecting and/or connecting any
electrical wiring, be careful not to damage or
abrade any of the wiring
4.2.1 Disconnect Means
A means for disconnecting the power to the heat
pump must be located within sight of the equipment
and installed in accordance with local code.
