ACCESSORIES

CHOOSING A SITE

• Before choosing the installation site, obtain user approval.

Caution

• When moving the unit during or after unpacking, make sure to lift it by holding its lifting lugs.  Do not exert any pressure on 

other parts, especially the refrigerant piping, drain piping and flange parts.
Wear protective gears (gloves and so on) when installing the unit.

• If you think the humidity inside the ceiling might exceed 30°C and RH80%, reinforce the insulation on the unit body.

Use glass wool or polyethylene foam as insulation so that it is no thicker than 10mm and fits inside the ceiling opening.

• Optimum air distribution is ensured.
• The air passage is not blocked.
• Condensate can drain properly.
• The ceiling is strong enough to bear the weight of the indoor unit.
• A false ceiling does not seem to be at an incline.
• Sufficient clearance for maintenance and servicing is ensured.
• Piping between the indoor and outdoor units is within the allowable limits. 

(Refer to the installation manual for the outdoor unit.)

• The indoor unit, outdoor unit, power supply wiring and transmission wiring is at least 

1 meter away from televisions and radios. This prevents image interference and 
noise in electrical appliances. (Noise may be generated depending on the conditions 
under which the electric wave is generated, even if a one-meter allowance is 
maintained.)

Use suspension bolts to install the unit. Check whether or not the ceiling is 
strong enough to support the weight of the unit. If there is a risk that the 
ceiling is not strong enough, reinforce the ceiling before installing the unit.

(Installation pitch is marked on the carton box for installation. Refer to it to check 
for points requiring reinforcing.) Select the *H dimension such that a downward 
slope of at least 1/100 is ensured as indicated in 

“DRAIN PIPING WORK”

.

• The installation pitch is listed on the packing material, and should be 

checked when deciding whether to reinforce the location or not.
