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.

Fig. 3.1

Step 3: Drill wall hole for connective piping

You must drill a hole in the wall for refrigerant piping, the drainage pipe, and the signal cable that will connect the indoor and outdoor units.

1. Determine the location of the wall hole based on the position of the mounting plate. Refer to

Mounting Plate Dimensions on the

next page to help you determine the optimal position. The wall hole should have a 65mm (2.5in) diameter at least, and at a slightly lower angle to facilitate drainage.

2. Using a 2.5in (65-mm) core drill, drill a hole in the wall. Make sure that the hole is drilled at

a slight downward angle, so that the outdoor end of the hole is lower than the indoor end by about 0.2-0.275in (5mm to 7mm). This will ensure proper water drainage. (See Fig. 3.2)

3. Place the protective wall cu in the hole. This protects the edges of the hole and will help seal it when you nish the installation process.

CAUTION

When drilling the wall hole, make sure to avoid wires, plumbing, and other sensitive components.

knock-out panel in place. If the wall hole is to the side of the indoor unit, remove the plastic knock-out panel from that side of the unit. (See Fig. 3.3). This will create a slot through which your piping can exit the unit. Use needle nose pliers if the plastic panel is too dicult to remove by hand.

3. Use scissors to cut down the length of the insulating sleeve to reveal about 15cm (6in) of the refrigerant piping. This serves two purposes:

• To facilitate the Refrigerant Piping

Connection process

• To facilitate Gas Leak Check s and enable

you to check for dents

4. If existing connective piping is already embedded in the wall, proceed directly to the Connect Drain Hose

step. If there is no embedded piping, connect the indoor unit’s refrigerant piping to the connective piping that will join the indoor and outdoor units. Refer to the Refrigerant Piping Connection section of this manual for detailed instructions.

5. Based on the position of the wall hole relative to the mounting plate, determine the necessary angle of your piping.

6. Grip the refrigerant piping at the base of the bend.

7. Slowly, with even pressure, bend the piping towards the hole. Do not dent or damage the piping during the process.

NOTE ON PIPING ANGLE

Refrigerant piping can exit the indoor unit from four dierent angles:

• Left-hand side

Page 15

Step 5: Connect drain hose

By default, the drain hose is attached to the lefthand side of unit (when you’re facing the back of the unit). However, it can also be attached to the right-hand side.

1. To ensure proper drainage, attach the drain hose on the same side that your refrigerant piping exits the unit.

2. Attach drain hose extension (purchased separately) to the end of drain hose.

3. Wrap the connection point rmly with Teon tape to ensure a good seal and to prevent leaks.

4. For the portion of the drain hose that will remain indoors, wrap it with foam pipe insulation to prevent condensation.

5. Remove the air ﬁlter and pour a small amount of water into the drain pan to make sure that water ﬂows from the unit smoothly.

NOTE ON DRAIN HOSE PLACEMENT

Make sure to arrange the drain hose according to Fig. 3.5.

DO NOT kink the drain hose.
