8.OPERATION

Most single phase units are operated without start relay or start capacitor. Such systems should
be off for a minimum of 5 minutes before restarting to allow equalization of pressures. The
thermostat should not be moved to cycle unit without waiting 5 minutes. To do so may cause
the compressor to stop on an automatic open overload device or blow a fuse. Poor electrical
service can cause nuisance tripping in overloads or blow fuses.

The compressor has an internal overload protector. Under some conditions, it can take up to 2
hours for this overload to reset. Make sure overload has had time to reset before condemning
the compressor.
