Safety Precautions
Read Safety Precautions Before Installation
Incorrect installation due to ignoring or not following installation and usage instructions can cause serious
damage or injury. The seriousness of potential damage or injuries is classified as either a WARNING
or CAUTION.
WARNING
CAUTION
WARNING
When connecting refrigerant piping, do not let substances or gases other than the specified refrigerant
enter the unit. The presence of other gases or substances will lower the unit’s capacity and can cause
Do not allow children to play with the air conditioner. Children must be supervised around the unit at
all times.
1. Installation must be performed by an authorized dealer or certified HVAC specialist. Defective or
incorrect installation can cause water leakage, electrical shock, or fire.
2. 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 requirement of NEC and
CEC by authorized personnel or a certified HVAC contractor only.)
3. Contact an authorized HVAC service technician for repair or maintenance of this unit.
4. Only use the included accessories, parts, and specified parts for installation. Using non-standard parts
can cause water leakage, electrical shock, fire, and can cause the unit to fail.
5. Install the unit in a firm location that can support the unit’s weight. If the chosen location cannot support
the unit’s weight, or the installation is not done properly, the unit may fall and cause serious injury
and damage.
This symbol indicates that you must never perform the action indicated.
abnormally high pressure in the refrigeration cycle. This can cause explosion and injury.
NEVER splice any electrical connection. A poor electrical connection, poor insulation or
voltage which is higher than permitted can cause fire.
WARNING (continued)
6. For all electrical work, follow all local and national wiring standards, regulations, and the Installation
Manual. You must use an independent circuit and single phase to supply power. Do not connect other
appliances to the same outlet. Insufficient electrical capacity or defects in electrical work can cause
electrical shock or fire.
7. For all electrical work, use the specified cables. Connect cables tightly, and clamp them securely to
prevent external forces from damaging the terminal. Improper electrical connections can overheat and
cause fire, and may also cause shock.
8.9. All wiring must be properly arranged to ensure that the control board cover can close properly. If the
control board cover is not closed properly, it can lead to corrosion and cause the connection points on
the terminal to heat up, catch fire or cause electrical shock.
In certain functional environments, such as kitchens, server rooms, etc., the use of specially designed
air-conditioning units is highly recommended.
CAUTION
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
gas accumulates around the unit, it may cause fire.
Do not operate your air conditioner in a wet room such as a bathroom or laundry room. Too much
exposure to water can cause electrical components to short circuit.
1. The product must be properly grounded at the time of installation or electrical shock may occur.
2. Install drainage piping according to the instructions in this manual. Improper drainage may cause water
damage to your home and property.
Note about Fluorinated Gasses
1. This air conditioning unit contains fluorinated gasses. For specific information on the type of gas an
the amount, please refer to the relevant label on the unit itself.
2.
Installation, service, maintenance and repair of this unit must be performed by a certified HVAC technician.
3. Product uninstallation and recycling must be performed by a certified HVAC technician.
4.
If the system has a leak-detection system installed, it must be checked for leaks at least every
12 months.
5. When the unit is checked for leaks, proper record-keeping of all checks is strongly recommended.

Installation Instructions –
Indoor Unit
PRIOR TO INSTALLATION
Before installing the indoor unit, refer to the
label on the product box to make sure that the
model number of the indoor unit matches the
model number of the outdoor unit.
Step 1: Select installation location
Before installing the indoor unit, you must
choose an appropriate location. The following
standards will help you choose an appropriate
location for the unit.
Proper installation locations meet the
following standards:
Good air circulation
Convenient drainage
Noise from the unit will not disturb
other people
Firm and solid—the location will not vibrate
Strong enough to support the weight of
A location at least 40 in. (one meter) away
from all other electrical devices (e.g., TV,
radio, computer)
DO NOT install unit in the following
locations:
Near any source of heat, steam, or
combustible gas
Near flammable items such as curtains
or clothing
Near any obstacle that might block air
circulation
Near the doorway
In a location subject to direct sunlight
NOTE ABOUT WALL HOLE:
If there is no fixed refrigerant piping:
While choosing a location, be aware that you
should leave ample room for a wall hole (see
“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
both the left and right.
