NDOOR UNIT INSTALLATION
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.
(See figure 5)
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
figure 12 .
3 Tighten the upper nut.
NOTE Before installation of the unit (in case of installation
with duct, but no duct service opening): modify the
position of the air filters.
NOTE When installing an air inlet duct, select fixing screws
that shall stick out maximum 5 mm at the inside of the
flange.
This is to protect the air filter from damage during
maintenance of the filter.
NOTE The unit can be used with bottom suction by replacing
the interchangeable plate by the air filter holding plate.
