FINISHING
After the refrigerant pipe, inter-unit wires, and drain pipe have been connected, make sure they are supported and
fixed in place for the entire length.
Keep the power wires and system interconnection wires away from all factory wiring and piping.

TEST RUN
• Turn on the circuit breaker at least 12 hours before starting the system to preheat the compressor and
prevent damage.
To protect the compressor, power is supplied from the 208/230 VAC input to the unit to preheat the compressor.
• Check the following before starting a test run:
• That all pipes are connected securely without leaks.
• That the valve is open.
If the compressor is operated with the valve closed, the outdoor unit will become over pressurized, which may
damage the compressor or other components.
If there is a leak at a connection, air can be sucked in and the internal pressure further increases, which may
cause a burst or injury.
• Operate the air conditioner using the correct procedure as specified in the Owner’s Manual.
11
PERIODIC MAINTENANCE
• For an air conditioning system that is operated on a regular basis, cleaning and maintenance of the indoor/
outdoor units are strongly recommended.
As a general rule, if an indoor unit is operated for about 8 hours daily, the indoor/outdoor units will need to be
cleaned at least once every 3 months. This cleaning and maintenance should be carried out by a qualified
service person.
Failure to clean the indoor/outdoor units regularly will result in poor performance, icing, water leaking and even
compressor failure.
