Safety

Precautions

Warning

1. Installation MUST BE performed by an authorised dealer or specialist. Defective 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.

3. Contact an authorised 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 or fire, and cause the unit to fail.

5. Install the unit in a firm location that can support the units weight. If the chosen location cannot

support the units weight, or the installation is not done properly, the unit may drop and cause
serious injury or damage.

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 outlet to supply power.
DO NOT connect other apppliances 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. 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.

9. In certain functional environments, such as kitchens, server rooms, etc., the use of specically

designed air-conditioning units is highly recommended.

10. If the supply cord is damaged, it MUST BE replaced by the manufacturer, its service agent or

similarly qualified persons in order to avoid a hazard.

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
are standards that 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 the

unit

 A location at least one meter 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.
