Usage

1Being exposed to direct airflow for an extended period of time could be hazardous to your health. Do not expose occupants, pets, or plants to direct airflow for extended periods of time.

2Due to the possibility of oxygen deficiency, ventilate the room when using together with stoves or other heating devices.

3Do not use this air conditioner for non-specified special purposes (e.g. preserving precision devices, food, pets, plants, and art objects). Usage in such a manner could harm such property.

Cleaningandmaintenance

1Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling sharp metal edges.

2Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation, leading to possible electric shock.

Care and Maintenance

Care and Maintenance

Turn the power off and unplug the power plug before cleaning the air conditioner.

AirFilter

The air filter behind the inlet grille should be checked and cleaned at least once every 2 weeks (or as necessary) to maintain optimal performance of the air conditioner.

1 The grille may be opened from the top for easy maintenance after installation.

2 Open the inlet grille by pulling off the exposed door on the top of the unit (based on installation).

3 Pull the tab slightly to release the filter. Pull the filter in the same direction as the opening.

4 Clean the filter with warm, soapy water. The water should be below 40°C (104°F).

5Rinse off and gently shake off excess water from the filter. Let it dry before replaceing it.

Drainage

The base pan may overflow due to high humidity. To drain the excess water, remove the drain cap from the back of the unit and secure the drainpipe.

Care and Maintenance

Howto AttachDrainPan(Optional)

The air conditioner employs a proper drain method whereby the condensed water (moisture removed from the air) is drained to the outside.

In very humid weather, (and for reverse cycle models in the reverse mode) excessive condensate water removed from the air may cause some water to collect. To remove this excess water you can install the drain pan as detailed below.

1Take the drain pan which is located in the air discharge.

2Remove the hole rubber from the base-pan (for some models).

3Install the drain pan to the right corner of the cabinet with 4 (or 2) screws.

4Connect the drain hose of 15mm inside diameter to the outlet located at the bottom of the drain pan.You can purchase the drain hose or tubing locally to satisfy your particular needs. (Drain hose is not supplied).
