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
AVERTISSEMENT
POSSIBILITÉ DE CHOCS ÉLECTRIQUES.
Ce système de chauffage contient du fi lage
de haut voltage. Un contact avec ces fi ls peut
résulter en des blessures sérieuses ou la mort.
Débranchez le circuit de puissance avant de
relier la pompe à chaleur
AVISO
PELIGRO DE DESCARGA ELÉCTRICA.
Esta bomba de calor, contiene cableado
de alta tensión. El contacto con los cables
podría ocasionar lesiones graves o la muerte.
Desconecte el circuito de alimentación, antes
de conectar la bomba de calentar.
CAUTION
Label all wires prior to disconnection when
servicing controls. Wiring errors can cause
improper and dangerous operation. Verify proper
operation after servicing.
ATTENTION
Au moment de l’entretien des commandes,
étiquetez tous les fi ls avant de les débrancher.
Des erreurs de câblage peuvent entraîner un
fonctionnement inadéquat et dangereux.
PRECAUCIÓN
Proceda a etiquetar todos los cables antes de su
desconexión en los controles de mantenimiento.
Los errores de cableado pueden ocasionar
un funcionamiento peligroso e inadecuado.
Comprobar que el funcionamiento es correcto,
una vez efectuado el mantenimiento.
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 and Figure 9 for 3-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 (CEC) C22.1,
unless local code requirements indicate otherwise.
The heat pumps come factory-wired intended for
use with either 208/230 VAC, 60 Hz single phase or 3
phase 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
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 11).
3. Remove the front cover of the sheet metal junction
box.
4. 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 11 for
connection location.
5. Connect the wires to the terminals on the main
contactor as shown in the wiring diagrams. Refer
to Figures 8 and 9.
6. Connect the ground wire to the ground lug
provided in the electrical compartment.
7. Replace the cover of the junction box.
8. Replace the service access panel and replace the
screws to hold it in place.
9. Connect a copper bonding wire (6 ga) to the
bonding lug on the right side of the heat pump.
