COOLING SYSTEM
!CAUTION
To prevent compressor and/or property damage, if power to the compressor has been off or inter- rupted 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.

TROUBLESHOOTING

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 blower does not come on and the word COOL is flashing, the compressor lockout feature is operating (see Lockout Bypass Option to tempo- rarily 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.
