part.

1. Being 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.

2. Due to the possibility of oxygen deficiency, ventilate the room when used

together with stoves or other heating devices.

Installation

Select the Best Location

1. Measure the space for installation to assure a good

fit. The air conditioner must be installed firmly into

place to prevent vibration and noise.

2. Avoid exposure to direct sunlight.

3. Remove all obstacles from the rear of the unit.

There must be at least 50cm (20in.) of cleared

space around the rear of the unit. Obstacles

restricting the airflow may reduce the cooling

efficiency of the unit.

4. The unit should be installed with a slight tilt

towards the outside (approx. 3°) to allow

condensed water to drain. (About 10~15mm or 1/4

bubble with level)

The external grille must be exposed outside for

air discharge.

NOTICE

Remove the Air Conditioner From the Case

1. Remove 2 shipping screws from the back of the case.

2. Remove the 2 screws on each side of the case. Keep these for later use.

3. Slide out the air conditioner from the case by pulling the base-pan handle while bracing the case.

4. Remove the white Styrofoam shipping block from the compressor. (Applicable for some models)

Attaching the Drain Pan (Optional)

The drain pan is used to collect condensed water.

The base-pan may overflow due to high humidity. The base-pan may also collect excess water when in

reverse mode (in Reverse Cycle models only). To drain the excess water, remove the drain cap from the back

of the unit and secure the drainpipe as follows:

1. Remove the drain pan located in the air discharge or on the barrier.

2. Remove the rubber cap from the hole on the base-pan. (Not applicable to all models)

3. Install the drain pan to the left corner of the cabinet with 2-4 screws.
