Safety Precautions 2

Read Safety Precautions Before Installation

Incorrect installation due to ignoring instructions can cause serious damage or injury.

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

WARNING

• 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

This air-conditioning unit contains ﬂuorinated gases. For speciﬁc information on the type of gas

and the amount, please refer to the relevant label on the unit itself.

Installation, service, maintenance and repair of this unit must be performed by a certiﬁed

technician.

Product uninstallation and recycling must be performed by a certiﬁed technician.

If the system has a leak-detection system installed, it must be checked for leaks at least every 12

months.

When the unit is checked for leaks, proper record-keeping of all checks is strongly recommended.

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

installers or contractors who are licensed HVAC professionals and in compliance with

all local, state and provincial laws.

Failure to observe a caution may result in injury or equipment damage.

WARNING

• Securely install the indoor unit on a structure

that can sustain its weight. If the structure is

too weak, the unit may fall causing personal

injury, unit and property damage, or even

death

• DO NOT install the indoor unit in a bathroom

or laundry room as excessive moisture can

short the unit and corrode the wiring.

CAUTION

• Install the indoor and outdoor units, cables

and wires at least 1m (3.2’) from televisions

or radios to prevent static or image

distortion. Depending on the appliances, a

1m (3.2’) distance may not be sufﬁcient.

• If the indoor unit is installed on a metal

part of the building, it must be grounded.

The ceiling is horizontal and its structure can

sustain the weight of the indoor unit.

The air inlet and outlet are not impeded.

The airﬂow can ﬁll the entire room.

There is no direct radiation from heaters.

CAUTION

DO NOT install the unit in the following

locations:

Where oil drilling or fracking is taking place.

Coastal areas with high salt content in the air

Near geothermal activity and corrosive gas

Buildings that may experience power

fluctuations

Enclosed spaces

Areas with strong electromagnetic waves

Areas that store flammable materials or gas

Rooms with high humidity, such as

bathrooms or laundry rooms

Air outlet

Air inlet

Air filter(on selected models)

Drain hose

Step 3: Duct and accessories installation

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.

1. Install the filter (optional) according to the size

of the air inlet.

5. Refer to the following static pressure guidelines

when installing the indoor unit.

Change the fan motor static pressure

according to external duct static pressure.

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.

4. Connect the duct according to the following

NOTE:

Confirm the minimum drain tilt is 1/100

or more.

CAUTION

The unit body must be completely aligned with

the hole. Ensure that the unit and the hole are

the same size before moving on.

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.

Install hanging screw bolts.

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.

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.

Secure the bolt using the washers and nuts

provided.

Install the four suspension bolts.

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).

9. Mount the indoor unit onto the hanging

screw bolts with a block. Position the

indoor unit flat using a level indicator to

prevent leaks. (See Fig. 4.9).
