Installation Places for
Outdoor Unit
You need to select adequate installation location considering the following conditions, and make sure to acquire the consent of the user.
-If an awning is built over the unit to prevent direct sunlight or rain exposure, make sure that heat radiation from the condenser is not restricted.
-Ensure that the spaces indicated by arrows around front, back and side of the unit are respected.
-Do not place animals and plants in the path of the warm air.
-Take the air conditioner weight into account and select a place where noise and vibration are minimum.
-Select a place so that the warm air and noise from the air conditioner do not disturb neighbors.
-Select a place that can sufficiently endure the weight and vibration of the outdoor unit and where even installation is possible.
-Select a place that has no direct impact of snow or rain
-Select a place with no danger of snowfall or icicle drop
-Select a place without weak floor or base such as decrepit part of the building or with a lot of snow accumulation
-Install at a place with fluent water draining to prevent damage from localized heavy rain and avoid frequent flooded area.

Seasonal Wind and Cautions
in Winter
-Sufficient measures are required in a snow area or severe cold area in winter so that product can operate well.
-Get ready for seasonal wind or snow in winter even in other areas.
-Install a suction and discharge duct not to let in snow or rain.
-Install the outdoor unit not to come in contact with snow directly. If snow piles up and freezes on the air suction hole, the system may malfunction. If it is installed at snowy area, attach the hood to the system.
-Install the outdoor unit at the higher installation console by 50 cm than the average snowfall (annual average snowfall) if it is installed at the area with much snowfall.
-Where snow accumulated on the upper part of the Outdoor Unit by more than 10 cm, always remove snow for operation.
