WARNING:
To avoid electric shock, personal injury, or death,
turn off the electric power at the disconnect
or the main service panel before making any
electrical connections.
• Electrical connections must be in compliance with all
applicable local codes 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).
Line Voltage Wiring
It is recommended that 115VAC line voltage be supplied
to the furnace from a dedicated branch circuit containing
the correct fuse or circuit breaker for the furnace.
IMPORTANT NOTE: An electrical disconnect must be
installed readily accessible from and located within
sight of the furnace. Refer to the wiring diagram inside
the control box cover or Figures 38 & 39 (pages 33
& 34) for the wiring of your particular unit.
Any other
wiring methods must be acceptable to authority
having jurisdiction.
CAUTION:
Label all wires prior to disconnection when
servicing controls. Wiring errors can cause
improper and dangerous operation. Verify
proper operation after servicing.
IMPORTANT NOTE:
Proper line voltage polarity must
be maintained in order for the control system to
operate correctly. Verify the incoming neutral line is
connected to the white wire and the incoming “hot”
line is connected to the black wire. The furnace will not
operate unless the polarity and ground are properly
connected as shown in Figure 25.
Route all electrical wiring to the left side of the furnace
(See Figure 24). For installation of “A” Cabinet furnaces,
allow suffi cient slack in the wiring if an optional cooling coil
cabinet is added at a later time.
Use of copper conductors
is recommended.
Connecting Power Supply Wires
1. Remove the furnace control panel cover.
2. Route wires (115 VAC) through the strain relief on the
left side of the furnace control box (Figure 24).
3. Connect the
hot
wire to the
black
pigtail lead, and
the
neutral
wire to the
white
pigtail lead. Secure all
connections with suitable wire nuts.
4. Connect the
ground
wire to the grounding screw.
5. Reinstall the control panel cover and secure with the
original mounting screws.
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 généra-
teur d’air chaud avant de prodéder aux travaux
d’entretein.
• Au moment de l’entretien des commandes,
étiquetez tous les fi ls avant de les débrancher.
S’assurer de les raccorder correctement.
• S’assurer que l’appareil fonctionne adéquatement
aprés l’entretien.
