• The microprocessor in the indoor unit should not be too close to RF noise sources.

Strictly comply with the following rules to prevent damage to the indoor unit and human injury:

• Do not put a heavy article on the indoor unit (even when packaged).

• Carry in the indoor unit as it is packaged if possible. If you must carry it unpacked, use a buffering cloth to avoid damage.

• To move the indoor unit, do not apply force to the refrigerant pipe, drain pan, foamed parts, or resin parts.

• Carry the package by two or more persons, and do not bundle it with a plastic band at positions other than specified.

• When installing, consider the air discharge direction and select a place where air can circulate evenly in a room. Avoid places where cooling will be uneven.

Cutting a Hole (for rear piping):

1. Decide the hole position for piping at 110 mm from the arrow mark (⇨) on the installation plate. Drill a hole (Dia 80 mm) at a slight downward slant toward the outdoor side.

NOTE: When drilling a wall that contains a metal lath, wire lath, or metal plate, be sure to use a pipe hole brim ring (sold separately).

Mounting the Installation Plate:

1. Securely fit the installation plate onto the wall by screwing it in the upper and lower parts to hook up the indoor unit.

2. To mount the plate on a concrete wall, use anchor bolts in the designated anchor bolt holes.

3. Install the installation plate horizontally in the wall.

NOTE: Secure four corners and lower parts of the installation plate with 6 mounting screws to install it.

• For block, brick, concrete, or similar walls, make 5 mm dia. holes and insert clip anchors for the mounting screws.

CAUTION: Failure to firmly install the unit may result in personal injury and property damage if the unit falls. When installing with a mounting screw, do not use the anchor bolt hole, as the unit may fall.

The piping can be routed from the rear right, rear left, bottom left, left, bottom right, or right. For leftward, bottom-leftward, and rear-leftward connections, you must change the drain hose and drain cap.

1. Die-cutting Front Panel Slit:

Cut out the slit on the left or right side of the front panel for left or right connection, or the slit on the bottom for bottom connection, using a pair of nippers. After scribing the slits with a knife or marking-off pin, cut them with nippers or an equivalent tool.

2. Changing Drain Hose:

• How to remove the drain hose: Remove the screw securing the drain hose and then pull out the drain hose. Be careful of any sharp edges of the steel plate.

• How to install the drain hose: Insert the drain hose firmly until the connection part contacts the heat insulator, and then secure it with the original screw.

• How to remove the drains cap: Clip the drain cap with needle-nose pliers and pull it out.

• How to fix the drains cap: Insert a hexagonal wrench (dia. 4 mm) into the center head and firmly insert the drains cap. Do not apply lubricating oil. Ensure there is no gap.

CAUTION: Firmly insert the drain hose and drain cap; otherwise, water may leak.

For a left-hand connection, follow these steps:

1. Bend the connecting pipe so that it is laid within 43 mm from the wall surface. If it exceeds 43 mm, the indoor unit may be unstable on the wall.

2. When bending the connecting pipe, use a spring bender to avoid crushing the pipe. Bend the pipe within a radius of 30 mm.

NOTE: If the pipe is bent incorrectly, the indoor unit may be unstable. After passing the pipe through the hole, connect it to the auxiliary pipes and wrap the facing tape around them.

Proper insulation is crucial to prevent condensation and trouble. Follow these instructions:

• Use the provided heat insulator to insulate the indoor unit connection completely so there are no gaps.

• Securely apply insulation all the way up to the pipe connecting section of the indoor unit so that there is no exposed area. Exposed pipes can cause water leaks.

• When wrapping the heat insulator around pipes, make sure the slit aperture faces toward the ceiling surface.

• Both connecting pipes (gas and liquid) must be insulated separately. Use polyethylene foam as the insulating material.

• Bind the auxiliary pipes (two), power supply wiring, and control wiring together with facing tape. For leftward piping, bind only the two auxiliary pipes with facing tape.

• Carefully arrange pipes so they do not stick out from the rear plate of the indoor unit.

• When bending a pipe, be careful not to crush it.

1. Pass the pipe through the hole in the wall, and hook the indoor unit on the installation plate at the upper hooks.

2. Swing the indoor unit to the right and left to confirm that it is firmly hooked on the installation plate.

3. While pressing the indoor unit onto the wall, hook it at the lower part of the installation plate. Pull the indoor unit toward you to confirm it is firmly hooked.

For detaching the indoor unit: Pull the indoor unit toward you while pushing its bottom up at the specified parts.

REQUIREMENT: The lower part of the indoor unit may float due to piping conditions. If you cannot fix it to the installation plate, use the provided screws to fix the unit and the plate. This is especially important when pipes are pulled out from the left side.

Follow these guidelines for proper drainage:

1. Run the drain hose sloped downwards. The through-wall hole should also be made at a slight downward slant to the outdoor side.

2. Put water in the drain pan to make sure that water is drained outdoors.

3. If connecting an extension drain hose, insulate the connecting part with the provided shield pipe.

• Do not raise the drain hose at any point.

• Do not form the drain hose into a wavy shape.

• Do not put the end of the drain hose into water.

• Do not let the end of the drain hose rest in a drainage ditch where water can collect.

• Ensure the ground is at least 50 mm below the end of the hose.

CAUTION: Arrange the drain pipe for proper drainage from the unit. Improper drainage can result in dew-dropping. Do not store the power cord and other parts at a height above the drain guide inside the unit.
