SPLIT-TYPE ROOM AIR CONDITIONER

inStallation inStructionS – indoor unit

PRIOR TO INSTALLATION

Before installing the indoor unit, refer to the label on the product

box to make sure that the model number of the indoor unit

matches the model number of the outdoor unit.

Step 1: Select installation location

Before installing the indoor unit, you must choose an appropriate

location. The following are standards that will help you choose an

appropriate location for the unit.

Proper installation locations meet the following standards:



Good air circulation



Convenient drainage



Noise from the unit will not disturb other people



Firm and solid—the location will not vibrate



Strong enough to support the weight of the unit



A location at least one meter from all other electrical devices

(e.g., TV, radio, computer)

DO NOT install unit in the following locations:

Near any source of heat, steam, or combustible gas

Near flammable items such as curtains or clothing

Near any obstacle that might block air circulation

Near the doorway

In a location subject to direct sunlight

NOTE

About wall hole

If there is no fixed refrigerant piping:

While choosing a location, be aware that you should leave ample

room for a wall hole (see Drill wall hole for connective piping step)

for the signal cable and refrigerant piping that connect the indoor

and outdoor units.

The default position for all piping is the right side of the indoor unit

(while facing the unit).

However, the unit can accommodate piping to both the left

and right.
