• Carefully read the Safety Precautions before installation.

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

units specically designed for this purpose is highly recommended.

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

conditioning unit. This is a complex system for a DIY person without proper tools or training.

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, earthquakes and other perils that might aect

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 carries a serious health and safety risk.

Note about Fluorinated Gasses

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

and 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

technician.

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

4. 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 appliance must be installed in

accordance with national and local codes and regulations.

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

CAUTION

•Use a stud nder to locate studs to prevent

unnecessary damage to the wall.

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

to minimise vibration & excessive noise.

Area around the outdoor unit should be

free from obstructions.

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

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 wind.

Ensure the location of the unit will not be

subject to snowdrifts, accumulation of leaves

or other seasonal debris. If possible, locate

the unit under an awning. 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, install the unit away from where

it can be 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 1 meter

distance may not be enough to eliminate all

interference.

• Make sure you refer to Length

Speciﬁcations to ensure there is

enough room for installation and

maintenance.
