General Maintenance
Regular checks, maintenance and care should be performed by professional personnel, which
will prolong the unit life span.
Outdoor Heat Exchanger
The outdoor heat exchanger should be checked and cleaned once every two months. Use
a vacuum cleaner with a nylon brush to clean up dust and debris on the surface of the heat
exchanger. Blow away dust by compressed air if available. Never use water to wash the heat
exchanger.
Drain Pipe
Regularly check to see if the drain pipe is clogged in order to ensure drain condensate doesn't
overflow and cause water damage.
Check Before Seasonal Use
1. The inlet and outlet of the indoor and outdoor units are not clogged or obstructed.
2. The power and communication cables are securely attached and that there is no visible
damage to any of the electrical wiring.
3. The batteries of the wireless remote controller have been replaced.
4. The filter screen has been cleaned and replaced securely.
5. After long periods of shutdown, open the main power switch 8 hours before operating the
unit so as to preheat the compressor.
6. The outdoor and indoor units are installed securely.
7. If there is anything abnormal, please contact the installing dealer or qualified service
technician.
