Installation example
(See
Indoor unit installation
Check whether the ceiling is strong enough to support the weight of
the indoor unit.
When installing optional accessories (except for the air inlet panel),
read also the installation manual of the optional accessories.
Depending on the field conditions, it may be easier to install optional
accessories before the indoor unit is installed.
1.
Install the indoor unit temporarily.
• Attach the hanger bracket to the suspension bolt. Be sure to
fix it securely by using a nut and washer from the upper and
lower sides of the hanger bracket.
2.
Check if the unit is horizontally levelled.
• Do not install the unit tilted. The indoor unit is equipped with a
built-in drain pump and float switch.
(If the unit is tilted against condensate flow, the float switch
may malfunction and cause water to drip.)
• Check if the unit is levelled at all four corners with a water
level or a water-filled vinyl tube as shown in
.
3.
Tighten the upper nut.
