1. INSTALLA

To install properly

TION PRECAUTION

, please read this manual at first.

AGE

If the supply cord is damaged, it must be replaced by the
manufacturer or its service agent or a similarly qualified person
in order to avoid a hazard.

An all-pole disconnection switch having a contact separation of
at least 3mm in all poles should be connected in fixed wiring.

The appliance shall be installed in accordance with national
wiring regulations.

The temperature of refrigerant circuit will be high, please keep
the interconnection cable away from the copper tube.

An all-pole disconnection device which has at least 3mm
separation distance in all pole and a residual current
device(RCD) with the rating of above 10mA
in the fixed wiring according to the national rule.

The power cord type designation is H05RN-R/H07RN-F or above.

shall be incorporated

2. INSTALLATION PLACE

Indoor Unit

●

Enough room for installation and maintenance.

●

The ceiling is horizontal and it can afford the weight of the indoor
unit.

The air conditioner must be installed by qualified persons.

When installing the indoor unit or its tubing, please follow this
manual as strictly as possible.

When all the installation work is finished, please turn on the power
only after a thorough check.

No further announcement if there is any change of this manual
caused by product improvement.

NOTE

The installor
and maintain the air-conditioner, as well as remind users to
carefully read and keep both Installation Manual and Owner's
Manual well.

should illustrate to users how to correctly use

CAUTION

DISPOSAL˖Do not dispose this product as unsorted municipal
waste. Collection of such waste separately for special treatment
is necessary.

●

The air inlet and outlet are not impeded and does not af
outdoor air too much.

●

The air flow can reach every part of the room.

●

The connecting pipe and drainpipe can be easily extracted out.

●
There is no direct radiation from heat source.

Outdoor Unit

●
Enough room for installation and maintenance.

●

The air inlet and outlet are not impeded and does not af
outdoor air too much.

●

Dry and well ventilated place.

●

The

supporter is flat and horizontal and can afford the weigh of

outdoor unit, without noise and vibration.

●

The noise and the outlet air will not influence your neighbor.

●

No combustible gas.

●

Place convenient for piping and wiring.

Please keep away from the following places, or malfunction may

Notes Before Installation

Select the correct carry-in path.

Move this unit as originally packaged as possible.

●

If the air conditioner is installed on a metal part of the building, it

●
must be electrically insulated according to the relevant standards
to electrical appliances.

●

●

Avoid installing it in a narrow sapce which has a high requirement
to noise.

NOTE

Remark per

For to prevent flicker impressions during the start of the
compressor (technical process), following installation
conditions apply.

●

The power connection for the air conditioner has to be done
at the main power distribution.The distribution has to be of
a low impedance, normally the required impedance reaches
at a 32A fusing point.

●

No other equipment has to be connected with this power
line.

●

For detailed installation acceptance, please refer to your
contract with the power supplier if restrictions do apply for
products like washing machines, air conditioners or
electrical ovens.
