COOLING SYSTEM
!CAUTION
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.
