3. Installation of Outdoor Unit
3.1 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
partdepending on installation status. Thus, use anti-vibration materials (cushion pad) fully (The base pad shall
bemore than 200mm).
WARNING
• Install where it can sufficiently support the weight of the outdoor unit.
If the support strength is not enough, the outdoor unit may drop and hurt people.
• Install where the outdoor unit may not fall in strong wind or earthquake.
If there is a fault in the supporting conditions, the outdoor unit may fall and hurt people.
• Please take extra cautions on the supporting strength of the ground, water outlet treatment(treatment
of the water flowing out of the outdoor unit in operation) of heat pump unit, and the passages of the pipe
and wiring, when making the ground support.
• Do not use tube or pipe for water outlet in the Base pan. Use drainage instead for water outlet.
The tube or pipe may freeze and the water may not be drained. (Heat pump model)
WARNING
• Be sure to remove the Pallet(Wood Support) of the bottom
side of the outdoor unit Base Pan before fixing the bolt. It
may cause the unstable state of the outdoor settlement, and
may cause freezing of the heat exchanger resulting in
abnormal operations.
• Be sure to remove the Pallet(Wood Support) of the bottom
side of the outdoor unit before welding. Not removing
Pallet(Wood Support) causes hazard of fire during welding.
