WARNING
Cleaning the air filter and other parts of the air filter involves dangerous work in high places, so be
sure to have a service person to do it.
Do not attempt to do it by yourself.
To avoid the possibility of electric shock, always turn off power to the system before performing any
cleaning or maintenance to the system. Turn off the outdoor disconnect switch located near outdoor
unit.
Operating the system with dirty filters may damage the indoor unit and could cause reduced cooling
performance.
Periodic Maintenance - periodic maintenance is recommended to ensure proper operation of the unit.
Recommended maintenance intervals may vary depending on the installation environment, e.g. dusty zones, etc.
Refer to table below.
Periodic Maintenance
REQUIREMENT
Be sure to clean the heat exchanger with pressurized water.
If a commercially available detergent (strong alkaline or acid) cleaning agent is used, the surface treatment of the
heat exchanger will be marred, which may degrade the self cleaning performance.
For further details, contact the dealer.
