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 qualied 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 sulde 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 airow 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 ammable gas.
• Install the indoor unit on the wall where the height from the oor 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.

Note:
1. Be sure sides A, B, and C are free from block­age/obstacles to allow sufcient clearance for air ow and maintenance.
2. When the outdoor unit is higher than the indoor unit, to prevent rain from owing inside, make a “U-bend” trap in the line.

• Connect the indoor unit rst, then the outdoor unit. Bend and arrange the piping carefully.
• Do not allow the piping to loosen from the indoor unit during installation.
• Be sure not to let the drain hose slack.
• Insulate both pipes.
• Do not allow the power cable and control cable to be crossed.

3. Indoor Unit Installation
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.
4. Electrical Work
• Connect unit to a dedicated circuit.
• Refer to the unit’s rating plate from proper supply voltage.
A.
B.
C.
D.
E. All wiring to the unit and interconnecting between indoor and out-
door units must comply with local and national electrical codes. F. Do not exceed the power code by splicing. G. Voltage should be in range of 90%~110% of unit’s voltage. H. The indoor unit is powered through the interconnecting cable. The
indoor unit requires no separate power source.
Heat Controller, Inc. INSTALLATION INSTRUCTIONS SMA/SMH 09/12
5. Connecting Cables
A. Indoor/outdoor connections should be 18 AWG or heavier, SJOW cord. Check the rating plate for minimum
circuit to select wire size.
B. Open the panel, remove the electrical box cover by loosening the screw for (for <12000Btu/h models).
Remove the panel and screw covers, then loosen the screws and take down the frame (for ≥ 12000Btu/h
models). C. Connect the wires to the terminals on the control board individually according to the outdoor unit connection. D. Wrap the cables not connected with terminals with electrical tape so that they will not touch any electrical
components.

6. Piping and Wrapping
A. For the left-hand and right-hand piping, remove the rear
plate bushing from the left side of the rear plate.
B. Wind the line set, drain hose and wiring with tape se-
curely and evenly. Consult local and national electrical codes for proper routing and placement of electrical wiring.
C. When installing the indoor unit lower than the outdoor
unit, make a “u-bend” trap to prevent rain water from running along the connecting pipe to the inside of the building/room where the indoor unit is located.

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 ow.
• 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 rm, 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
Fit the seal into the drain elbow, then insert the drain elbow into the outdoor unit’s base pan hole, rotate 90° to securely assemble them. To discharge excessive condensate from the outdoor unit when in heating mode, connect the drain elbow to a
