Caution
• All bolts should be made from high quality carbon steel (with
galvanized surface or other rust prevention treatment) or
stainless steel.
• How the ceiling should be handled will differ with the type of
building. For specific measures, please consult the building
and renovation engineers.
• How the lifting bolt is secured depends on the specific
situation, and it must be secure and reliable.
3.2 Installation of the Indoor Unit
(1) When mounting the lifting lugs of the indoor unit on the lifting bolts,
slot the nut washers of the lifting bolts in the oblong holes of the
lifting lugs. The upper and lower nuts and the washers are shown
in Figure 3.5.
(2) Adjust the height of the indoor unit.
(3) Use a spirit level to verify that the unit body is level (making the
unit body slope downwards towards the drainage side), as shown
in Figure 3.6.
