Preparation for Extended Non-Operation:
If you plan to not run the unit for an extended period of time (e.g. from the end of summer to the beginning of
the following summer), perform the following:
1. Clean the indoor unit and filters as outlined in the previous steps.
2. Operate the unit in FAN-Only mode for at least 8 hours to dry out the inside of the unit.
3. Turn off the unit. Then, turn off the power to the circuit at the breaker. The unit should be the only
appliance on this circuit.
4. Remove the batteries from the remote control.
5. The outdoor unit also requires periodic maintenance. However, it is highly recommended you contact a
qualified service professional to perform this. Please DO NOT attempt to do this on your own.
Pre-Season Inspection:
After prolonged non-operation perform the following:
1. Use a dry cloth to wipe off any dust that has accumulated on the air intake grille. This will avoid any dust
from being dispersed from the indoor unit.
2. Check for any damaged or disconnected wires.
3. Clean or replace the filters and ensure they are properly installed.
4. Check for water and oil leaks.
5. Check for blockages in the airflow inlet and outlet.
6. Replace batteries in the remote control.
