F. ELECTRICAL
CONNECTIONS
When installing or servicing this equipment, ALWAYS
exercise basic safety precautions to avoid the possibility of
electric shock.
1. Power wiring and _'ounding
of equipment
must
comply
with local codes.
2. Power supply must agree with equipment
nameplate.
3. Install
a separate
disconnect
switch at the outdoor
unit.
4. Ground
the outdoor unit per local code requirements.
5. Provide flexible electrical
conduit
whenever
vibration
transmission
may create a noise problem within
the
structure.
6. The use of color coded low voltage wire is recommended
to simplify connections
between
the outdoor unit, the
thermostat
and the indoor unit.

8. Mount the indoor thermostat
in accordance
with instruc-
tion included
with the thermostat.
Wire per appropriate
hook-up diagram
(included
in these instructions).
G. COMPRESSOR

After all electrical
wiring is complete,
SET THE THERMO-
STAT SYSTEM
SWITCH
IN THE OFF POSITION
SO
COMPRESSOR
WILL NOT RUN, and apply power by
closing the system
main disconnect
switch.
This will activate
the compressor
sump heat (where used).
Do not change the
