INSTALLATION REQUIREMENTS

Review the following information before installing the unit: 
• Do not install the indoor units near a direct source of heat such as 

direct sunlight or a heating appliance.

• Allow sufficient space for airflow and unit servicing. See Fig. 6 for 

the minimum required distances between the unit and the walls or 

ceilings.

• Communication wiring must be at least 3 ft. (1m) away from all 

electromagnetic interference (televisions, radios, etc.) sources. 

Interference is still possible even if this distance is maintained.

• Ensure any hanger used is strong enough to withstand the unit’s 

weight.

• If the indoor unit is installed in an unconditioned space, 

running for long periods of time when the temperatures are 
outside the recommended indoor unit operation ranges, it is 
recommended to seal all the corners of the indoor unit to 
prevent any leakage and add insulation material (13/32 to 13/
16 in (10-20 mm)) to the entire surface of the indoor unit to 
avoid condensation or heat transfer.

NOTE: Nuisance sweating may occur if the unit is installed in a 
high humidity environment with low airflow.

Table 3 — Operating Range

NOTE: DO NOT install the indoor or outdoor units in a location 
with special environmental conditions. For those applications, 
contact your Ductless representative

PRODUCT INSTALLATION

• Installation must be performed by an authorized dealer or 

specialist. A defective installation can cause water leakage, 

electrical shock, or fire.

• The installation must be performed according to the installation 

instructions. Improper installation can cause water leakage, 

electrical shock, or fire. (In North America, installation must be 

performed in accordance with the requirements of NEC or CEC 

by authorized personnel only.)

• Contact an authorized service technician for repair or 

maintenance of this unit. This appliance must be installed in 

accordance with local codes.

• Only use the included accessories, parts, and specified parts for 

installation. Using non-standard parts can cause water leakage, 

electrical shock, fire, or unit failure. 

• Install drainage piping according to the instructions in this 

manual and in accordance with local codes. Improper drainage 

may cause water damage to your home and property.

• For units that have an auxiliary electric heater, 

DO NOT

 install 

the unit within 3 feet (1 meter) of any combustible materials.

DO NOT

 install the unit in a location that may be exposed to 

combustible gas leaks. If combustible gas accumulates around 

the unit, it may cause a fire.

DO NOT

 turn on the power until all work has been completed.

• When moving or relocating the system, consult experienced 

service technicians for the disconnection and re-installation of 

the unit.

WARNING

Securely install the indoor unit on a structure that can sustain its
weight. If the structure is too weak, the unit may fall and cause
personal injury, unit and property damage, or death.

DO NOT

 install the indoor unit in a bathroom or laundry room as

excessive moisture can short the unit and corrode the wiring.

WARNING

Install the indoor and outdoor units, cables and wires at least 3.2 ft 
(1m) from televisions, routers, computer equipment or radios to 
prevent static or image distortion. Depending on the appliances, a 
3.2 ft (1m) distance may not be sufficient. 

If the indoor unit is installed on metal, it must be electrically
grounded.
