INDOOR UNIT

 WARNING

THE CHOICE OF MOUNTING SITE

 

(Please note the following matters and obtain permission from customer before installation.)

• The unit should be mounted at stable, non-vibratory location

which can provide full support to the unit.

 CAUTION

• No nearby heat source and no obstruction near the air

outlet is allowed.

• The clearance distances from top, right and left are

specified in figure below.

• The location must be convenient for water drainage and

pipe connection with the Outdoor unit.

• To avoid interference from noise, please place the unit and

its remote controller at least 1m from the radio and
television.

• To avoid any error in signal transmission from the remote

controller, please put the controller far away from high-
frequency machines and high-power wireless systems.

OUTDOOR UNIT

 WARNING

• The Outdoor unit must be mounted at a location which can

support heavy weight. Otherwise, noise and vibration will
increase.

 CAUTION

• Do not expose the unit under direct sunshine or rain.

Besides, ventilation must be good and clear of obstruction.

• The air blown out of the unit should not point directly to

animals or plants.

• The clearances of the unit from top, left, right and front are

specified in figure below. At least three of the above sides
must be open air.

• The installation height should be at least 2,300 mm or more

from the floor.

• Be sure that the hot air blown out of the unit and noise do

not disturb the neighbourhood.

• Do not install at a location where there is flammable gas,

steam, oil and smoke.

• The location must be convenient for water drainage.
• Place the Outdoor unit and its connecting cord at least 1 m

away from the antenna or signal line of television, radio or
telephone. This is to avoid noise interference.
