INSTALLATION REQUIREMENTS

• A location which is convenient to installation and not exposed to 

strong winds.

• A location which can bear the weight of the outdoor unit and 

where the outdoor unit can be mounted in a level position.

• A location which provides appropriate clearances (see Fig. 7).
• Allow sufficient space for airflow and service of the unit. See Fig. 

7 for the required minimum distances between the unit or walls.

NOTE:

 

DO NOT

 install the indoor or outdoor units in a location with 

special environmental conditions. For those applications, contact your 
Ductless representative.

INSTALLATION

Step 1 - Check Equipment

Unpack the unit and move to the final location. Remove the carton, 
taking care not to damage the unit. Inspect the equipment for damage 
prior to installation. File a claim with the shipping company if the 
shipment is damaged or incomplete.

Locate the unit rating plate which contains the proper installation 
information. Check the rating plate to ensure the unit matches the job 
specifications.

Step 2 - Mount Unit

1. Select the installation location of the outdoor unit following the 

installation requirements. To prevent high wind exposure, install the 

outdoor unit with the air inlet side facing the wall (see fig 9).

Fig. 9 — High Wind Installation

2. Use a rigid base to support the unit in a level position. If conditions 

or local codes require the unit be attached to a pad, tie down bolts 

should be used and fastened through knockouts provided in unit 

base pan. Refer to unit mounting pattern in Fig. 3 to determine base 

pan size and knockout hole location. For hurricane tie downs, 

contact distributor for details and PE (Professional Engineer) 

Certification, if required. For extreme outdoor conditions 

applications refer to the 'Cold Climate Application Guideline 

Ductless.

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. 

• To prevent exposure to wind, install the outdoor unit with its air 

inlet side facing the wall

• Install drainage piping according to the instructions in this 

manual. Improper drainage may cause water damage to your 

home and property.

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

Strong

wind

EQUIPMENT DAMAGE HAZARD

Failure to follow this caution may result in equipment damage or 
improper operation.
In regions with snowfall and cold temperatures, avoid installing 
the outdoor unit in areas where it can be covered by snow. 
Blocking the air intake may result in reduced airflow, significantly 
reduced performance and damage to the equipment.

CAUTION
