Safety Precautions 2

Read and Understand All Safety Precautions Before Installation

Incorrect installation due to negligence of instructions can lead to serious damage or injury.

The magnitude of potential damages 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. This is a comfort cooling system.

• Only trained and certied technicians should install, repair, and service this air

conditioning unit.

Installation by unqualied persons is highly ill-advised, and can cause diminished performace, as

well as risk of damage to equipment or nearby persons.

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

Improper installation may lead to electrical shock, short circuit, leaks, ﬁre or other damage to

the equipment.

• Before installing the unit, consider strong winds, earthquakes, or other hazards that might aect

your unit, and locate it accordingly. Failure to do so could cause equipment failure.

• After installation, ensure that there are no refrigerant leaks and that the unit is operating properly.

Refrigerant and/or oil in the system is toxic, ﬂammable, and poses a serious health and safety risk.

Note about Fluorinated Gasses

1. This air-conditioning unit contains ﬂuorinated refrigerant, commonly known as R410a.

For the charged amount, please refer to the relevant label on the unit side panel.

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

technician possessing specialized training and specic tools.

3. Product removal and recycling must also be performed by a certiﬁed technician.

4. If the system has a leak-detection feature 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 severe injury or death. The appliance must be

installed in full accordance with all relevant national regulations.

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

Safety Precautions

CAUTION

•This illustration is for demonstration

purposes only.

The actual shape of your air conditioner may

be slightly dierent.

Copper lines must be independently and

individually insulated.

•

CAUTION

•To prevent wall damage, use a stud nder

to locate studs.

A minimum pipe run of 3 m. (10’) is needed

to minimize vibration and excessive noise.

A, B, and C air circulation clearance area and

pathways must be free from obstructions

at all times.

Outdoor Unit Installation Instructions

Step 1: Select installation location.

The outdoor unit should be installed at a location

in accordance with the following guidelines:

Place the outdoor unit as close to the indoor

units 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 winds.

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 the 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.

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. 6.1 & 6.2)

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 1m (3’)

distance may not be enough to eliminate all

interference.

Step 2: Install outdoor unit.

Fix the outdoor unit with anchor bolts (M10 or 3/8”)

>60cm / 24”

Fix with bolts

CAUTION

• Be sure to remove any obstacles that

may block air circulation.

• Make sure you refer to length

speciﬁcations to ensure there is

enough room for installation and

maintenance.
