2 Make the ceiling opening needed for installation where
applicable. (For existing ceilings.)
- Refer to the paper pattern for installation for the ceiling
opening dimensions.
- Create the ceiling opening required for installation. From the
side of the opening to the casing outlet, implement the
refrigerant and drain piping and wiring for remote controller
(unnecessary for wireless type). Refer to each piping or
wiring section.
- After making an opening in the ceiling, it may be necessary
to reinforce ceiling beams to keep the ceiling level and to
prevent it from vibrating. Consult the builder for details.
3 Install the suspension bolts. (Use either a W3/8 or M10 size
bolt.)
Use anchors for existing ceilings, and a sunken insert, sunken
anchors or other field supplied parts for new ceilings to reinforce
the ceiling in order to bear the weight of the unit. Adjust
clearance from the ceiling before proceeding further.
Installation example (See figure 5)
INSTALLATION PROCEDURES FOR FRESH AIR
INTAKE DUCT CONNECTION
1 Preparing the connection hole. (See figure 10)
- Cut off the knockout hole on the side plate with a nipper.
- Cut the insulation of the hole portion with a cutter.
2 Placing the insulation. (See figure 11)
- Put the insulation tightly around the hole of the unit as
shown. The ends of the side plate and the inner insulation
must be completely adhered without leaving any clearance
along the circumference of the hole. Make sure the inner
surface of insulation tightly contacts the inner insulation edge
and the side plate.
INDOOR UNIT INSTALLATION
When installing optional accessories (except for the decoration
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. However, for existing
ceilings, install fresh air inlet component kit and branch duct before
installing the unit.
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.
- Securing the hanger bracket (See figure 6)
2 Fix the paper pattern for installation. (For new ceilings only.)
- The paper pattern for installation corresponds with the
measurements of the ceiling opening. Consult the builder for
details.
- The centre of the ceiling opening is indicated on the paper
pattern for installation. The centre of the unit is indicated on
the unit casing and on the paper pattern for installation.
- After removing the packaging material from the paper pattern
for installation, attach the paper pattern for installation to the
unit with the attached screws as shown in figure 7.
- Adjust the height of the unit until it matches the indication in
figure 7.
3 Adjust the unit to the right position for installation.
(See "Preparations before installation" on page 2.)
4 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 14.
5 Remove the paper pattern for installation. (For new ceilings
only.)
NOTE
Installation is possible with a ceiling dimension of
910 mm (marked with*). However, to achieve a ceiling-
panel overlapping dimension of 20 mm, the spacing
between the ceiling and the unit should be 35 mm or
less. If the spacing between ceiling and the unit is over
35 mm, attach ceiling material to the part or recover
the ceiling.
