Indoor Unit Installation
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.
Refer to the following diagram to ensure proper distance from walls and ceiling:
15cm (5.9in) or more
12cm (4.75in) or more
12cm (4.75in) or more
2.3m (90.55in) or more
Step 2: Attach mounting plate to wall
The mounting plate is the device on which you will mount the indoor unit.
● Take out the mounting plate at the back of the indoor unit.
● Secure the mounting plate to the wall with the screws provided. Make sure that mounting plate is flat against the wall.
NOTE FOR CONCRETE OR BRICK
WALLS:
If the wall is made of brick, concrete, or similar material, drill 5mm-diameter (0.2indiameter) holes in the wall and insert the sleeve anchors provided. Then secure the mounting plate to the wall by tightening the screws directly into the clip anchors.
28
Owner’s Manual &
Installation Manual
Step 3: Drill wall hole for connective piping
1. Determine the location of the wall hole based on the position of the mounting plate. Refer to Mounting Plate
Dimensions .
2. Using a 65mm (2.5in) or 90mm (3.54in)
(depending on models )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 5mm to 7mm (0.2-0.275in). This will ensure proper water drainage.
3. Place the protective wall cuff in the hole. This protects the edges of the hole and will help seal it when you finish the installation process.

NOTE: When the gas side connective pipe is ø16mm (5/8in) or more, the wall hole should be 90mm (3.54in).
29
Owner’s Manual &
Installation Manual
Step 4: Prepare refrigerant piping
The refrigerant piping is inside an insulating sleeve attached to the back of the unit. You must prepare the piping before passing it through the hole in the wall.
1. Based on the position of the wall hole relative to the mounting plate, choose the side from which the piping will exit the unit.
2. If the wall hole is behind the unit, keep the 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. This will create a slot through which your piping can exit the unit. Use needle nose pliers if the plastic panel is too difficult to remove by hand.
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. To ensure proper drainage, attach the drain hose on the same side that your refrigerant piping exits the unit. Attach drain hose extension (purchased separately) to the end of drain hose.
● Wrap the connection point firmly with
Teflon tape to ensure a good seal and to prevent leaks.
● For the portion of the drain hose that will remain indoors, wrap it with foam pipe insulation to prevent condensation.
● 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.
