four lifting lugs without exerting any pressure on other parts, especially, the refrigerant piping.
When it may exceed 30
°
C and RH80% in the ceiling or fresh air is inducted into the ceiling, an addi-
tional insulation (Thickness 10mm or more of glasswool or polyethylene form) is required.

tomer’s approval.
• Install the product in buildings that use gypsum boards (9.5mm thick or more) for ceiling materials because
