Auto Operation

During Auto Operation:
❏ You cannot switch the indoor fan speed. It has already been set by the Fuzzy rule.
❏ If the system is not operating as desired, manually switch to another mode. The system will not automatically switch from the cooling mode to the heating mode, or from heating to cooling, it must be done by manually resetting.

Whentheairconditionerisnotgoingtobeusedforalongtime.

When air conditioner is not going to be used for a long time.

1. Operate the air conditioner on Air circulation mode (Refer to page 14) for 2 to 3 hours.
   • This will dry out the internal mechanisms.

2. Turn off the circuit breaker, and disconnect the plug.

Operation Tips

Do not overcool the room.
This is not good for the health and wastes electricity.
Make sure that the doors and windows are shut tight.
Avoid opening doors and windows as much as possible to keep the cool air in the room.

Keep blinds or curtains closed.
Do not let direct sunshine enter the room when the air conditioner is in operation.
Clean the air filter regularly.
Blockages in the air filter reduce the airflow and lower cooling and dehumidifying effects. Clean at least once every two weeks.

Keep the room temperature uniform.
Adjust the vertical and horizontal airflow direction to ensure a uniform temperature in the room.
Ventilate the room occasionally.
Since windows are kept closed, it is a good idea to open them and ventilate the room now and then.
