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.

! WARNING

 - Disconnect all electrical power to the unit before servicing. Disconnect power to

both the indoor and outdoor units. NOTE: There may be more than one electrical disconnect switch.
Failure to shut off power can cause electrical shock resulting in personal injury or death.

11.If checking the unit on the heating cycle in the wintertime, when the outdoor coil is cold enough
to actuate the defrost control, observe at least one defrost cycle to make sure the unit defrosts properly.
12.Check the refrigerant charge (see Instructions under "Charging the System").
13.Replace service port caps. Service port cores are for system access only and will leak if not tightly
capped.
14.Check unit for tubing and sheet metal rattles.
15.Instruct the owner on operation and maintenance.
Leave this "Installation and Operating Manual" and the "Use and Care Manual" with owner.
