INDOOR UNIT INSTALLATION

PRIOR TO INSTALLATION

Before installing the indoor unit, check the label on the product box to see if the model number of the indoor unit matches the one of the outdoor unit.

Step 1: Select the installation location.

Before installing the indoor unit, consult the standards below to help you choose an appropriate location for the unit.

Proper installation location standards:

• Good air circulation• Convenient drainage• Noise from the unit will not disturb other

people• Stable and solid—the location should not

vibrate• Strong enough to support the weight of the

unit• Leave at least one meter distance from other

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

DO NOT install the unit in locations that are:

• Near any source of heat, steam, or combustible gas

• Near combustible items such as curtains or clothing

• Near any obstacles that might block air circulation

• Near the doorway• Away from direct sunlight

NOTE ABOUT THE WALL HOLE

If there is no fixed refrigerant piping: While choosing a location, be aware that you should leave adequate space for a wall hole (see Drill wall hole for connective piping step) for signal cable and refrigerant piping connecting the indoor unit with the outdoor unit. 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 the walls and ceiling:

4.75 inor more

90.55 in or more

4.75 inor more

5.9 in or more

Step 2: Attach the mounting plate to the wall.

The mounting plate is used to support the indoor unit.• Take out the mounting plate at the back of

the indoor unit.

• Secure the mounting plate to the wall with the supplied screws. Make sure that the mounting plate is flat against the wall.

Note: If the wall is made of brick, concrete, or similar material, drill 0.2 in-diameter holes in the wall and insert in the supplied sleeve anchors. Secure the mounting plate to the wall by tightening the screws into the clip anchors.

28

Installation

Step 3: Drill a hole through the wall for feeding the pipes outside.1. Determine the location of the wall hole based

on the position of the mounting plate. Refer to the Mounting Plate Dimensions.

2. Use a 2.5 inch or 3.54 inch (depending on models ) core drill to drill a hole in the wall. Make sure that the hole is drilled at a slightly downward angle, so that the outdoor end of the hole is lower than the indoor end by about 0.2 to 0.275 inches. This will ensure proper water drainage.

3. Place the protective wall cuffprotective wall cuff in the hole. This protects the edges of the hole and will help seal it when you finish the installation process.

WARNING

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

Step 4: Prepare the 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.

Knock-out Panel

3. 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.

NOTE ON PIPING ANGLE

Refrigerant piping can exit the indoor unit from four different angles: Left-hand side, right-hand side, left rear, and right rear.

WARNING

Be extremely careful not to dent or damage the piping while bending them away from the unit. Any dents in the piping will affect the unit’s performance.

Step 5: Connect the drain hose

By default, the drain hose is attached to the left-hand side of the 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 where your refrigerant piping exits the unit. Attach the drain hose extension (purchased separately) to the end of the 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.

NOTE ON DRAIN HOSE PLACEMENT

Make sure to arrange the drain hose according to the following figures.

Air Evacuation

Preparations and Precautions

Air and foreign matter in the refrigerant circuit can cause abnormal rises in pressure, which can damage the air conditioner, reduce its efficiency, and cause injury. Use a vacuum pump and manifold gauge to evacuate the refrigerant circuit and remove any incondensable gas and moisture from the system. Evacuation should be performed upon initial installation and when the unit is relocated.

Before Performing Evacuation

• Ensure the connective pipes between the indoor and outdoor units are connected properly .

• Ensure all wiring is connected properly.

Evacuation Instructions

1. Connect the charge hose of the manifold gauge to the service port of the low pressure valve on the outdoor unit.

2. Connect another charge hose from the manifold gauge to the vacuum pump.

3. Open the low pressure side of the manifold gauge. Keep the high pressure side closed.

4. Turn on the vacuum pump to evacuate the system.

5. Run the vacuum for at least 15 minutes, or until the Compound Meter reads -76cmHG (-10 5Pa).

Electrical and Gas Leak Checks

BEFORE THE TEST RUN

Do not perform the test run until the following steps have been completed:

• Electrical Safety Checks - Confirm that the unit’s electrical system is safe and operating properly. After installation, confirm that all electrical wiring is installed in accordance with local and national regulations, and according to the Installation Manual.

• Gas Leak Checks - Check all flare nut connections and confirm that the system is not leaking.

• Confirm that the gas and liquid (high and low pressure) valves are fully open.

• Check Grounding Work - Measure grounding resistance by visual detection and with a grounding resistance tester. Grounding resistance must be less than 0.10.

Note: This may not be required for some locations in the US.

DURING THE TEST RUN

1. Check for Electrical LeakageDuring the Test Run, use an electro-probe and multimeter to conduct a comprehensive electrical leakage test. If electrical leakage is detected, turn off the unit immediately and call a licensed electrician to find and resolve the cause of the leakage.Note: This may not be required for some locations in the US.

WARNING - RISK OF ELECTRIC SHOCKALL WIRING MUST COMPLY WITH LOCAL AND NATIONAL ELECTRICAL CODES AND MUST BE INSTALLED BY A LICENSED ELECTRICIAN.

2. Gas Leak Checks

There are two different methods to check for gas leaks.

• Soap and Water MethodUse a soft brush to apply soapy water or liquid detergent to all pipe connection points on the indoor unit and outdoor unit. The presence of bubbles indicates a leak.

• Leak Detector MethodIf using a leak detector, refer to the device’s operation manual for proper usage instructions.

• After Performing Gas Leak ChecksAfter confirming that the all pipe connection points do not leak, replace the valve cover on the outside unit.

COMMON ISSUESThe following problems are not system malfunction issues and in most situations will not require repairs.

ISSUE POSSIBLE CAUSES

Unit does not turn on when pressing the ON/OFF button.

The Unit has a 3-minute protection feature that prevents the unit from overloading. The unit cannot be restarted within three minutes of being turned off.

The unit changes from COOL/HEAT mode to FAN mode.

The unit may change its setting to prevent frost from forming on the unit. Once the temperature increases, the unit will start operating in the previously selected mode.

The set temperature has been reached, at which point the unit turns off the compressor. The unit will continue operating when the temperature fluctuates again.

The indoor unit emits white mist.

In humid regions, a large temperature difference between the room’s air and the conditioned air can cause white mist.

Both the indoor and outdoor units emit white mist.

When the unit restarts in HEAT mode after defrosting, white mist may be emitted due to the moisture generated from the defrosting process.

The indoor unit makes noises.

A rushing air sound may occur when the louver resets its position.

A squeaking sound may occur after running the unit in HEAT mode due to the expansion and contraction of the unit’s plastic parts.

Both the indoor unit and outdoor unit make noises.

Low hissing sound during operation: This is normal and is caused by refrigerant gas flowing through both indoor and outdoor units.

Low hissing sound when the system starts, has just stopped running, or is defrosting: This noise is normal and is caused by the refrigerant gas stopping or changing direction.

Squeaking sound: Normal expansion and contraction of plastic and metal parts caused by temperature changes during operation can cause squeaking noises.

The outdoor unit makes noises.

The unit will make different sounds based on its current operating mode.

Dust is emitted from either the indoor or outdoor unit.

The unit may accumulate dust during extended periods of non-use, which will be emitted when the unit is turned on. This can be mitigated by covering the unit during long periods of inactivity.

The unit emits a bad odor.

The unit may absorb odors from the environment (such as furniture, cooking, cigarettes, etc.) and emit them during operations.

The filters on the unit have become moldy and should be cleaned.

The fan of the outdoor unit does not operate.

During operation, the fan speed is controlled to optimize product operation.

Operation is erratic, unpredictable, or unit is unresponsive.

Interference from cell phone towers and remote boosters may cause the unit to malfunction. In this case, try the following:• Disconnect the power, then reconnect.• Press the ON/OFF button on the remote control to restart operation.
