6.1 Foundation for Installation
• Check the strength and level of the installation ground so that the unit will not cause any operating vibration or
noise after installation.
• Fix the unit securely by means of the foundation bolts. (Prepare 4sets of M12 foundation bolts, nuts and wash-
ers each which are available on the market.)
• It is best to screw in the foundation bolts until their length are 20mm from the foundation surface.
• Be sure to remove the Pallet(Wood Support) of the
bottom side of the unit Base Pan before fixing the
bolt. It may cause the unstable state of the unit set-
tlement, 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 unit before welding. Not remov-
ing Pallet(Wood Support) causes hazard of fire
during welding.
