Installation and operation manual

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) and indoor-outdoor unit wiring. 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 M8 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

INSTALLATION

When installing optional accessories, 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 (except for the decoration panel). 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 5

.

2.

Fix the paper pattern for installation. (For new ceilings
only.)

The paper pattern for installation corresponds with the measure-
ments 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
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 supplied screws as shown in 

figure 8

.

3.

Adjust the unit to the right position for installation.

(Refer to the chapter 

"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 9

.

5.

Remove the paper pattern for installation. (For new ceilings
only.)

PIPING

 

WORK

For refrigerant piping of outdoor unit, refer to the installation
manual supplied with the outdoor unit.

Execute heat insulation work completely on both sides of the
gas piping and the liquid piping. Otherwise, this can sometimes
result in water leakage.
(When using a heat pump, the temperature of the gas piping can
reach up to approximately 120°C. Use insulation which is
sufficiently resistant.)

Also, in cases where the temperature and humidity of the
refrigerant piping sections might exceed 30°C or RH 80%,
reinforce the refrigerant insulation (20 

mm or thicker).

Condensation may form on the surface of the insulating
material.

Before rigging tubes, check which type of refrigerant is used.

Use a pipe cutter and flare suitable for the used refrigerant.

Apply ether oil or ester oil around the flare portions before
connecting.

To prevent dust, moisture or other foreign matter from infiltrating
the tube, either pinch the end, or cover it with tape.

Use copper alloy seamless pipes (ISO 1337).

The outdoor unit is charged with refrigerant.

Be sure to use both a spanner and torque wrench together when
connecting or disconnecting pipes to/from the unit.

Do not mix anything other than the specified refrigerant, such as
air, etc.., inside the refrigerant circuit.

Refer to the table below for the dimensions of flare nuts and the
appropriate tightening torque. (Overtightening may damage the
flare and cause leaks.)
