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 qualied 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 sulde 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 wire-
less equipment.
• A location with abnormal environmental conditions such as locations where the unit is exposed to exces-
sively 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 airow 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 concentra-
tions 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.

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
drain hose (locally purchased).
