ACCESSORIES
SELECTING INSTALLATION 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 wall might exceed 30°C and RH80%, reinforce the insulation on the unit body.
Use glass wool or polyethylene foam as insulation so that the thickness is more than 10mm and fits inside the wall opening.
• Optimum air distribution is ensured.
• The air passage is not blocked.
• Condensate can drain properly.
• The wall/floor is strong enough to bear the weight of the indoor unit.
• 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.)
• The equipment is not intended for use in a potentially explosive atmosphere.
