Installation
Foundation for Installation
• Fix the unit tightly with bolts as shown below so that unit will not fall down due to earthquake or gust.
• Use the H-beam support as a base support
• Noise and vibration may occur from the floor or wall since vibration is transferred through the installation
part depending on installation status. Thus, use anti-vibration materials (cushion pad) fully (The base pad
shall be more than 200mm).
WARNING
• Be sure to install unit in a place strong enough to withstand its weight.
Any lack of strength may cause unit to fall down, resulting in a personal injury.
• Have installation work in order to protect against a strong wind and earthquake. Any installation
deficiency may cause unit to fall down, resulting in a personal injury.
• Especially take care for support strength of the floor surface, water drain processing (processing of
water flown out from the outdoor unit during operation) and paths of the pipe and wiring when mak-
ing a base support.
• Don't use a tube or pipe for water drain in the base pan and perform water drain processing by
using the drain path. Water drain may not be done due to freezing of a tube or pipe.
