CAUTION
This heater must be connected to a bonding grid
with a solid copper wire not smaller in diameter
than 8 AWG (8,4 mm
2
).
4.3 Bonding
(Earthing)
Air Energy
™
and most installation 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 (8,4 mm
2
).
The heat pump, along with pumps and other pool
equipment must be connected to this bonding grid. A
bonding lug (earth terminal) is provided on the right
hand side of the heat pump to ensure this requirement is
met.
4.4
Pump Connection (Maintain Temp
Feature)
This feature allows the heat pump to turn on the
pool pump, bypassing the time clock setting, to maintain
the desired temperature. In order for the MAINTAIN
TEMP feature to be functional, a dedicated line from
the pool pump time clock to the Maintain Temp (Pump)
Relay is needed. See Figure 13.
4.5
Optional Remote Controls
Electrical wiring must be in accordance with all
applicable national and local codes and ordinances.
4.5.1
Connection to a Remote Pool-Off-
Spa Selector (3-Wire Connection)
4.5.1.1 Install the Remote Pool-Off-Spa
Selector
1.
Turn off the power to both the pool/spa control
system and the heat pump unit.
2. Remove the screws that attach the service/access
panel to the heat pump unit and the cover to the
junction box (see Figure 14).
3.
Run the wires from the pool/spa control system
into the conduit connection labeled “Low Voltage
Connection”, located on the lower right hand side
of the heat pump (see Figure 14).
4.
Connect the wiring from the pool/spa control
system to the heat pump remote control terminal
(see Figure 15a).
5.
Restore power to the heat pump and the pool/spa
control system.
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 10 for
single phase electrical wiring and Figure 11 for 3-phase
electrical wiring (See Figure 12 for electrical wiring
diagram symbol definitions). The heat pump must be
properly and reliably connected to a Protective Earth
(PE) conductor. There is a bonding lug (Protective Earth
terminal) on the right side of the heat pump, where a
protective earth (PE) conductor must be attached.
4.2 Main
Power
Electrical wiring to the heat pump must be in
accordance with applicabe local and/or national codes.
The heat pumps come factory-wired for use with either
208-230 VAC single phase or 380-420 VAC three phase,
50 Hz field electrical supply depending on the model.
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 AE-
Ti 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 four (4) screws that attach the service/
access panel to the heat pump unit (see Figure 14).
3.
Remove the one (1) screw in the front cover of the
sheet metal junction box.
4.
Remove the front cover of the sheet metal junction
box.
5.
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 labeled “High Voltage Connection” on
the right side of the heat pump. See Figure 14 for
connection location.
6.
Connect the wires to the terminals on the main
contactor as shown in the wiring diagram. Refer to
Figures 10 and 11.
7.
Connect the ground wire to the ground lug
provided in the electrical compartment.
8.
Replace the cover of the junction box.
9.
Replace the service access panel and replace the
screws to hold it in place.
10. Connect a copper bonding (earthing) wire [8 AWG
(8,4 mm
2
)] to the bonding lug (earth terminal) on
the right side of the heat pump.
