Installation Manual for Single Zone Ductless Mini-Split

For correct installation, read this manual before starting the installation. Please save this manual in a safe place.

Only trained and qualified service personnel should install, repair or service air conditioning equipment. Users should not install the air conditioner by themselves.

Pictures in this manual may be slightly different from the air conditioner you purchased. These pictures are only representations.

INSTALLATION PRECAUTION

Installation in the following places is not recommended.

Near equipment which contains or uses oil.

Coastal locations where exposure to high winds and high concentrations of salt in the air may damage the air conditioner.

A location with exposure to sulfide gas such as hot-spring resort.

Places where there are high frequency machines such as wireless equipment, welding machines, or in a medical facility. The unit uses a remote controller and may cause electrical interference with nearby wireless equipment.

A location with abnormal environmental conditions such as locations where the unit is exposed to excessively high or low ambient temperatures, exposure to adverse weather, corrosive fumes, dust laden or moisture-laden atmospheres and hazardous locations.

A location where there are combustible gases or volatile matter.

Recommended Areas of Installation

Indoor Unit

A place where there are no obstacles or blockages, near the inlet or outlet airflow areas of the unit.

A place which can bear the weight of the indoor unit.

A place which provides adequate clearance around the indoor unit as required.

A place 3.3ft or more away from TV or radio equipment to ensure there is no electronic/wireless interference.

A place which is far away from heat or steam sources and flammable gas.

Install the indoor unit on the wall where the height from the floor is more than 7.5 feet.

Outdoor Unit

A place which is convenient for installation and not exposed to a high winds or air with high concentrations of salt content.

A place which can bear the weight of the outdoor unit.

A place where the outdoor unit can be installed in a horizontal level position.

A place where the operation noise and discharge air will not disturb others.

A place free from leakage of combustible gases.

Where an allowable head level for the connective piping is less than 16 feet and length of the connective piping is less than 33 feet.

A place which provides recommended clearance around the outdoor unit.

Note:

1.The appliance should not be installed in the laundry room.

2.All the connections must be in accordance with local and national electric codes.

3.For power details of the air conditioner, refer to the rating plate of the product.

**Cautions on remote controller installation

Keep the remote controller at least 3 feet from the nearest TV set or stereo equipment to advoid possible electronic interference.

Do not leave the remote controller in a place exposed to direct sunlight or close to a heating source, such as a stove.

Ensure that the positive and negative poles are correct when inserting batteries into the remote controller.

Anchoring the Outdoor Unit

The outdoor unit should not be exposed to strong winds

Anchor the outdoor unit with o1/4" or 5/16" anchor bolts

Note:

1.Be sure sides A, B, and C are free from blockage/obstacles to allow sufficient clearance for air flow and maintenance.

2.When the outdoor unit is higher than the indoor unit, to prevent rain from flowing inside, make a “U-bend” trap in the line.

A.

B.Place the upper lip at the back of the indoor unit onto the upper hook of the installation plate. Move the indoor unit from side to side to see that is is secured onto the hook of the installation plate.

C.Push the lower part of the indoor unit up to the wall. Then move the indoor unit from side to side and up and down to ensure it is secured to the installation plate.

D.Piping can easily be installed by placing a piece of foam between the unit and the wall to assist in holding the unit away from the wall during installation.

OUTDOOR UNIT INSTALLATION

1. Outdoor Installation Precaution

Install the outdoor unit on a rigid base to prevent noise and vibration.

Locate the air outlet direction where the discharged air is not blocked. Ensure there are no obstacles blocking the unit’s air flow.

If the installation location is exposed to strong winds, place the unit length wise along a wall or use shield plates to protect against high winds.

If suspending the unit, the installation wall should be solid brick, concrete or of similar construction. If not, reinforce the supporting wall. The connections between the bracket and wall and the bracket and the air conditioner must be firm, stable and reliable. Consult all local and national building codes.

If suspending the unit, follow the instructions provided by the bracket manufacturer.

2. Drain Elbow Installation
