3. Foundation for Installation
• 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), 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.
• Install at places where it can endure the weight and vibration/noise of the outdoor unit.
• The outdoor unit supports at the bottom shall have width of at least 100mm under the Unit's legs before being
fixed.
• The outdoor unit supports should have minimum height of 200mm.
• Anchor bolts must be inserted at least 75mm.
• Fix the unit tightly with bolts as shown so that unit will not fall down due to earthquake or gust.
a. The corner part must be fixed firmly. Otherwise, the support for the installation may be bent.
b. Get and use M10 Anchor bolt.
c. 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)
d. Space for pipes and wiring (Pipes and wiring for bottom side)
e. Use the H-beam support as a base support
f. Concrete support
• Be sure to remove the Pallet (Wood Support) of the bottom of the outdoor unit before fixing the bolt or welding.
It may cause the unstable state of the outdoor settlement, and may cause freezing of the heat exchanger
resulting in abnormal operations, hazard of fire during welding.
