PRIOR TO INSTALLATION
Before installing the indoor unit, ensure the compatibility with the
outdoor unit using the product data as a reference. It is also necessary
to confirm the proper application of the equipment and to perform a
heat load calculation for proper sizing.
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 be sure the unit matches the job specifications.
The indoor unit should be installed in a location that meets the
following requirements:
• Enough room for installation and maintenance
• Enough room for the lineset and drainpipe
• A horizontal ceiling and a structure that can sustain the weight of
the indoor unit
• The air inlet and outlet are not impeded
CAUTION
DO NOT install the unit in the following locations:
• Areas with oil drilling or fracking
• Coastal areas with high salt content in the air
• Areas with caustic gases in the air, such as near hot springs
• Areas with power fluctuations, such as factories
• Enclosed spaces, such as cabinets
• Areas with strong electromagnetic waves
• Areas that store flammable materials or gas
• Rooms with high humidity, such as bathrooms or laundry rooms.
WARNING
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.
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.

Step 2 - Select the Installation Location
Before installing the indoor unit, choose an appropriate location.
The following are standards that should help you choose an
appropriate location for the unit.
Proper installation locations must meet the following standards:
1. Good air circulation
2. Convenient drainage
3. Noise from the unit will not disturb others
4. Firm and solid—the location will not vibrate
5. A location at least 3.28 ft. (1m) from all other electrical devices
(e.g., TV, radio, computer)
6. DO NOT install the unit in the following locations:
a.
b.
c.
d.
e.
NOTE: When selecting a location leave ample room for a wall
hole (refer to the drill wall hole for connective piping step) for the
signal cable and refrigerant piping that connect the indoor and
outdoor units. The default position for all piping is the right side
of the indoor unit (while facing the unit). However, the unit can
accommodate piping to either left or right.
