Line Voltage
• Electrical connections must be in compliance with all
applicable local codes and ordinances, and with the
current revision of the National Electric Code (ANSI/
NFPA 70). For Canadian installations the electrical
connections and grounding shall comply with the current
Canadian Electrical Code (CSA C22.1 and/or local
codes).
• Provide power supply for the unit in accordance with the
unit wiring diagram and the unit rating plate. The line
voltage to the unit should be supplied from a dedicated
branch circuit containing the correct fuse or circuit
breaker for the unit.
• An electrical disconnect must be located within sight
of and readily accessible to the unit
. This switch shall
be capable of electrically de-energizing the outdoor unit.
See unit data label for proper incoming field wiring. Any
other wiring methods must be acceptable to authority
having jurisdiction.
• A wiring diagram is located on the inside cover of the
control access panel of the outdoor unit. The installer
should become familiar with the wiring diagram before
making any electrical connections to the outdoor unit.
See Figures 15 & 16 (pages 38 & 39).
• If any of the original wires supplied with the unit must
be replaced, they must be replaced with material of the
same voltage, gauge, and temperature rating.
• Connect the line-voltage leads to the terminals on the
contactor inside the control compartment.
• Use only copper wire for the line voltage power supply
to this unit. Use proper code agency listed conduit and
connector for connecting the supply wires. Use of rain
tight conduit is recommended.
• Units are shipped from the factory wired for 230 or 460
volt operation. On 208-230V units being placed into 208
volt operation, remove the lead from the transformer
terminal marked 240V and connect it to the terminal
marked 208V.
• Overcurrent protection must be provided at the branch
circuit distribution panel and sized as shown on the
unit rating label and according to the National Electric
Code and applicable local codes. NOTE: See the unit
rating plate for maximum circuit ampacity and maximum
overcurrent protection limits.
Grounding
WARNING:
The unit cabinet must have an uninterrupted or
unbroken electrical ground to minimize personal
injury if an electrical fault should occur.
Do not
use gas piping as an electrical ground !
This unit must be electrically grounded in accordance
with local codes or, in the absence of local codes, with
the National Electrical Code (ANSI/NFPA 70) or the CSA
C22.1 Electrical Code. Use the grounding lug provided in
the control box for grounding the unit.
ELECTRICAL SHOCK, FIRE OR EXPLOSION
HAZARD
Failure to follow safety warnings exactly could
result in serious injury or property damage.
Improper servicing could result in dangerous
operation, serious injury, death or property
damage.
• Before servicing, disconnect all electrical
power to furnace.
• When servicing controls, label all wires prior
to disconnecting. Reconnect wires correctly.
• Verify proper operation after servicing.
WARNING:
RISQUE DE CHOC ÉLECTRIQUE, D’INCENDIE
OU D’EXPLOSION
Le non-respect des avertissements de sécurité
pourrait entraîner
un fonctionnement dangereux
de l’appareil, des blessures graves, la mort ou
des dommages matériels.
Un entretein incorrect pourrait entraîner un
fonctionnement dangereux de l’appareil, des
blessures graves, la mort ou des dommages
matériels
• Couper toute alimentation électrique au
générateur d’air chaud avant de prodéder
aux travaux d’entretein.
• Au moment de l’entretien des commandes,
étiquetez tous les fils avant de les débrancher.
S’assurer de les raccorder correctement.
• S’assurer que l’appareil fonctionne
adéquatement aprés l’entretien.
AVERTISSEMENT:
ELECTRICAL WIRING
Pre-Electrical Checklist
√
Verify that the voltage, frequency, and phase of the
supply source match the specifications on the unit rating
plate.
√
Verify that the service provided by the utility is sufficient
to handle the additional load imposed by this equipment.
See Table 13 (page 37) or the unit wiring label for proper
high and low voltage wiring.
√
Verify factory wiring is in accordance with the unit wiring
diagram. Inspect for loose connections.
√
For 3 phase units always check the phase balance
(page 14).
