White Rodgers 1F90W-71 - Manual (Page 8)

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
HEAT-OFF-COOL-AUTO
until COOL is displayed.
2. Press to adjust thermostat below room tem-
perature to call for cool. The blower should come on
immediately, followed by cold air circulation. How-
ever, if the red LED on the thermostat front is flashing,
the compressor lockout feature is operating (see
Lockout Bypass Option to temporarily override the
compressor lockout feature during testing).
If the thermostat display is operating properly, but the
cooling system does not operate when the above
steps are performed, the red jumper wire (provided
with thermostat) may not be properly installed be-
tween the RH and RC terminals. Disconnect electri-
cal power to system and properly install the jumper
wire per the appropriate wiring diagram.
After the system has been checked and is running prop-
erly, determine if automatic changeover is desired (see
SYSTEM CONFIGURATION).
Refer to the OPERATION GUIDE if you need additional
information on thermostat operation.
