The cabinet MUST have an uninterrupted or unbroken ground
according to NEC ANSI/NFPA 70-1999 and Canadian Elec-
trical 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. Failure to follow this
warning could result in electrical shock, fire, or death.

24-V WIRING

Make field 24-v connections at the 24-v terminal strip. (See Fig.
14.) Connect terminal Y as shown in Fig. 15 for proper operation
in cooling mode. Use AWG No. 18 color-coded wire only.
The 24-v circuit contains an automotive-type, 3-amp fuse located
on the main control. Any direct shorts 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.
