Outdoor unit
• The outdoor unit should be sited in a place where:
NOTE
Cannot be installed hanging from ceiling or stacked.
CAUTION
• Construct a large canopy.
• Construct a pedestal.
Precautions for humidifying hose installation work
• When embedding
G
humidifying hose:
Cannot be installed to the existing embedded piping. Embedding work is separately necessary.
• The length of the
G
humidifying hose is marked on the hose packing material.
• Turn on all the fluorescent lamps in the room, if any, and find the site where remote control signals are properly received by the
indoor unit (within 7m).
• Select a place where the remote controller is not hit by direct sunlight. (Selecting a place where direct sunlight hits the remote
controller makes it difficult for the remote controller to receive the signal from the indoor unit.)
1) the restrictions on installation specified in “
Indoor/Outdoor Unit Installation Drawings
” on page 6 are met,
2) the ground is solid enough to bear the weight and vibration of the unit and where the operating sound will not be amplified,
3) the hot air discharged from the unit or the operating sound will not cause a nuisance to the neighbors of the user,
4) there is no bedroom or the like nearby, so that the operating sound will cause no trouble,
5) there are sufficient spaces for carrying the unit into and out of the site,
6) both air inlet and outlet have clear paths of air (they should be free of snow in snowy districts),
7) there is no fear of inflammable gas leakage in a nearby place,
8) units, power cords and inter-unit wires at least 3m away from television and radio sets (This is to prevent interference to images
and sounds. Noises may be heard even if they are more than 3m away depending on radio wave conditions),
9) the unit is not directly exposed to salt, sulfidized gases, or machine oil vapour (they may shorten outdoor unit life),
10) nothing which must be kept away from moisture is under the unit since drain flows out of the outdoor unit,
11) the air is clean, and there are no sources of unpleasant odours close by.
When operating the air conditioner in a low outdoor ambient temperature, be
sure to follow the instructions described below.
• To prevent exposure to wind, install the outdoor unit with its suction side
facing the wall.
• Never install the outdoor unit at a site where the suction side may be
exposed directly to wind.
• To prevent exposure to wind, it is recommended to install a baffle plate
on the air discharge side of the outdoor unit.
• In heavy snowfall areas, select an installation site where the snow will not
affect the unit.
Install the unit high enough off
the ground to prevent burying
in snow.
1) Use an extension hose (option) when extending the
G
humidifying hose.
2) The length of the
G
humidifying hose needs to be set to ensure humidifying capacity. Cut off any excess hose.
Use the remote controller to set the hose length. (Refer to “
9. Setting the humidifying hose length
” on page 16.)
• If the
G
humidifying hose needs to be cut to be laid, cut it, lay it, and connect it using the
J
joint included with the outdoor unit or an
elbow (field supply). When doing this, wrap it to prevent air leaks with the
K
binding band included with the outdoor unit.
(Refer to “
4-2 Connecting the cut humidifying hoses
” on page 8.)
• When laying the
G
humidifying hose inside the wall, block the ends of the
G
humidifying hose with tape or the like to prevent water or
anything else from entering it until it is connected to the indoor unit and outdoor unit ducts.
