The seriousness of potential damage or injuries is classified as either a WARNING or CAUTION.

Failure to observe a warning may result in death. The product must be installed by

WARNING

CAUTION

WARNING

installers or contractors who are licensed HVAC professionals and in compliance with
all local, state and provincial laws.

• Carefully read the Safety Precautions before installation.

• In certain functional environments, such as kitchens, server rooms, etc., the use of specially

designed air-conditioning units is highly recommended.

• Only trained and certified technicians should install, repair and service this air
conditioning unit.

Improper installation may result in electrical shock, short circuit, leaks, fire or other damage to
the equipment and personal property.

• Strictly follow the installation instructions set forth in this manual.

Improper installation may result in electrical shock, short circuit, leaks, fire or other damage to
the equipment.

• Before you install the unit, consider strong winds, typhoons and earthquakes that might affect
your unit and locate it accordingly. Failure to do so could cause the equipment to fail.

• After installation, ensure there are no refrigerant leaks and that the unit is operating properly.
Refrigerant is both toxic and flammable and poses a serious health and safety risk.

Note about Fluorinated Gases

2.

Install and fit pipes and wires after you have
finished installing the main body.When
choosing where to start, determine the
direction of the pipes to be drawn out.
Especially in cases where there is a ceiling
involved, align the refrigerant pipes, drain
pipes, and indoor and outdoor lines with their
connection points before mounting the unit.

3.

Install hanging screw bolts.

Cut off the roof beam.
Strengthen the point at which the cut

was made. Consolidate the roof beam.

4. After you select an installation location,align
the refrigerant pipes, drain pipes, as well as
indoor and outdoor wires with their
connection points before mounting the unit.

5.

Drill 4 holes 10cm (4”) deep at the ceiling
hook positions in the internal ceiling. Be sure
to hold the drill at a 90° angle to the ceiling.

6.

Secure the bolt using the washers and nuts
provided.

7.

Install the four suspension bolts.

8.

Mount the indoor unit with at least two
people to lift and secure it. Insert suspension
bolts into the unit’s hanging holes. Fasten
them using the washers and nuts provided.
(See Fig. 4.8).

or more.

Step 3: Duct and accessories installation

1. Install the filter (optional) according to the size
of the air inlet.

2. Install the canvas tie-in between the body and
the duct.

3. The air inlet and air outlet duct should be far
enough apart enough to a avoid air passage
short-circuit.

Connect the duct according to the following

NOTE: 1. Do not place the connecting duct
weight on the indoor unit.

2. When connecting the duct, use an
nonflammable canvas tie-in to prevent
vibrating.

3. Insulation foam must be wrapped outside the
duct to avoid condensate. An internal duct
underlayer can be added to reduce noise,
if the end-user requires.

Outdoor Unit Installation Instructions

Step 1: Select installation location.

The outdoor unit should be installed in the
location that meets the following requirements:

√

 Place the outdoor unit as close to the indoor

unit as possible.

√

 Ensure that there is enough room for

installation and maintenance.

√

 The air inlet and outlet must not be

obstructed or exposed to strong wind.

√

 Ensure the location of the unit will not be

subject to snowdrifts, accumulation of leaves
or other seasonal debris. If possible, provide
an awning for the unit. Ensure the awning
does not obstruct airflow.

√

 The installation area must be dry and well

ventilated.

√

 There must be enough room to install the

connecting pipes and cables and to access
them for maintenance.

5

√

 The area must be free of combustible gases

and chemicals.

√

 The pipe length between the outdoor and

indoor unit may not exceed the maximum
allowable pipe length.

√

 If possible, DO NOT install the unit where it

is exposed to direct sunlight.

√

 If possible, make sure the unit is located far

away from your neighbors’ property so that
the noise from the unit will not disturb them.

√

 If the location is exposed to strong winds (for

example: near a seaside), the unit must be
placed against the wall to shelter it from the
wind. If necessary, use an awning.
(See Fig. 5.1 & 5.2)

√

 Install the indoor and outdoor units, cables

and wires at least 1 meter from televisions or
radios to prevent static or image distortion.
Depending on the radio waves, a 1 meter
distance may not be enough to eliminate all
interference.
