Страница: 21 / 52

WARNING:
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in electrical
shock, fire, or death.
The furnace casing MUST have an uninterrupted or
unbroken ground according to NEC ANSI/NFPA 70-
2002 and Canadian Electrical Code CSA C22.1 or local
codes to minimize personal injury if an electrical fault
should occur. This may consist of electrical wire or
conduit approved for electrical ground when installed in
accordance with existing electrical codes. Do not use gas
piping as an electrical ground.
J-BOX RELOCATION
1. Remove 2 screws holding auxiliary J-box. (See Fig. 30.)
2. Rotate J-box 180° and attach box to left side, using holes
provided.
WARNING:
FIRE OR ELECTRICAL SHOCK
HAZARD
Failure to follow this warning could result in intermittent
unit operation or performance satisfaction.
If manual disconnect switch is to be mounted on furnace,
select a location where a drill or fastener will not contact
electrical or gas components.
B. 24-V Wiring
Make field 24-v connections at 24-v terminal block. (See Fig. 32.)
Connect terminal Y/Y2 as shown in Fig. 27 and 28 for proper
cooling operation. Use only AWG No. 18, color-coded, copper
thermostat wire for lengths up to 100 ft. For wire lengths over 100
ft, use AWG No. 16 wire.
The 24-v circuit contains an automotive-type, 3-amp fuse located
on furnace control (See Fig. 32.) Any direct shorts of 24-v wiring
during installation, service, or maintenance could cause this fuse to
blow. If fuse replacement is required, use ONLY a 3-amp fuse of
identical size/type. The control will flash code 24 when fuse needs
replacement.

* Permissible limits of voltage range at which unit will operate satisfactorily.
† Unit ampacity = 125 percent of largest operating component’s full load amps plus 100 percent of all other potential operating components’ (EAC, humidifier, etc.) full load
amps.
‡ Length shown is a measured 1 way along wire path between unit and service panel for maximum 2 percent voltage drop.
** Time-delay type is recommended.
