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.
9.MISCELLANEOUS

- Do not allow the vapor line and liquid line to touch together this would cause an undesirable heat transfer resulting in capacity loss and increased power consumption 8

- Line insulation suction line requires insulation in order to prevent condensation from forming on the piping and to prevent heat gain caused by surrounding air generally 3 8 wall thickness of armflex or equivalent is satisfactory in severe application hot high humidity areas greater thickness may be required apply the line insulation by sliding it on the sealed tuing before cutting and making connections 8
- Liquid line does not necessarily need insulation however if they are exposed to high ambient temperatures i e kitchen boiler rooms hot attics rooftop surface then they should be insulated make sure to use the proper size tubing for the liquid line to prevent liquid refrigerant flashing to a vapor within the liquid line 8
