Manual operations and maintenance
3.1 Operation mode selection
While two or more indoor units are simultaneously operating, make sure the modes do not conflict
with each other. The heat mode claims precedence over all other modes. If the unit intially started to
operate in heat mode, the other units can operate in heat mode only. For example: If the unit intially
started operates under cool (or fan) mode, the other units can operate under any mode except heat.
If one of the unit selects heat mode, the other operating units will stop operation and diplay "--"
(for units with display window only) or the auto and operation indication light will flash rapidly, the
defrost indication light will turn off, and the timer indication light will remain on (for units without a
display window). Alternatively, the defrost and alarm indication light (if applicable) wil light up, or the
operation indication light will flash rapidly, and the timer indication light will turn off ( for the floor and
standing type).
3.2 Maintenance
If you plan to leave the unit idle for a long time, perform the following tasks:
1. Clean the indoor unit and air filter.
2. Select fan only mode and let the indoor fan run for a time to dry the inside of the unit.
3. Disconnect the power supply and remove the battery from the remote control.
4. Check the components of the outdoor unit periodically. Contact a local dealer or a customer service
centre if the unit requires servicing.

the power supply plug.
