COOLING SYSTEM
To prevent compressor and/or property damage,
if power to the compressor has been off or
interrupted for more than 1 hour and the outdoor
temperature is below 50°F, DO NOT operate the
system for at least the amount of time the com-
pressor was off! This will allow the compressor
heaters to warm the compressor oils to avoid
damage due to slugging.
1. Press
SYSTEM
SWITCH
until COOL is displayed.
2. Press to adjust thermostat to 40°F. All stages
of the cooling system should come on within approxi-
mately five minutes. However, if the compressor
lockout feature is operating, the fan will run but the
compressor will not operate (see Lockout Bypass
Option to temporarily override the compressor lock-
out feature during testing).
3. To program the thermostat, see OPERATION GUIDE.
CAUTION
!
After heating and cooling system have been checked and
are running properly, determine if automatic changeover
is desired. When option switch #4 is in the proper position,
automatic changeover is enabled by pressing the SYS-
TEM SWITCH until AUTO is displayed (see SET OPTION
SWITCHES).
Refer to the OPERATION GUIDE if you need additional
information on thermostat operation.
