REPARATIONS

 

 

 

BEFORE

 

 

 

INSTALLATION

 

1.

 

Suspension bolt position (Refer to 

figure 2

).

 

2.

 

The fan speed for this indoor unit is preset to provide standard
external static pressure.

 

 

If higher or lower external static pressure is required, reset
the external static pressure by changing the initial setting on
the terminal in the indoor switchbox. Refer to the section
entitled 

"Field setting" on page 4

.

 

3.

 

Install the suspension bolts (Refer to 

"Installation example" on

page 2

).

Use M10 size bolt for the suspension bolt. Use anchors for
existing ceilings, and a sunken insert, sunken anchor or other
field supplied parts for new ceilings to reinforce the ceiling to
bear the weight of the unit.

INSTALLATION

 

When installing optional accessories, refer to the instruction manual
of each optional accessory. 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.

 

Do not install the unit tilted.
(If the unit is tilted against condensate flow, water can drip out of
the drain pan).

Check if the unit is levelled at all four corners with a water level (1) or
a water-filled vinyl tube (2) (Refer to 

figure 3

).

 

3.

 

Tighten the upper nut.

 

4.

 

An air filter is installed to prevent dust accumulation on the heat
exchanger. This will prolong the lifetime of the unit.

 

5.

 

Connect the air inlet to the air inlet ducting and the air outlet to
the air outlet ducting. Always provide a flexible connection
between the ducting flanges of the air conditioner and the ducts
to prevent vibrations and noise generation.

PIPING

 

 

 

WORK

 

For refrigerant piping of outdoor unit, see the installation manual
attached to the outdoor unit.

 

 

The outdoor unit is charged with refrigerant.

 

 

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

 

 

The liquid line must be connected to the air conditioning unit via
a flare connection. The gas line must be welded directly to the
air conditioning unit piping. In case of a FDY125 unit, both the
liquid line and the gas line must be connected to the air
conditioning via a flare connection.

 

 

In case of flare connections, flare the pipe end neatly to avoid
refrigerants leaks.

 

 

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

figure 4

).

 

 

Refer to the table below for the dimensions of flare nut spaces.

 

 

Because R-407C/R-410A refrigerant is used, apply ether or
ester oil around the flare portions before connecting.

 

 

Refer to the table above to determine the proper tightening
torque. (Overtightening may damage the flare and cause leaks.)

 

 

Check the pipe connector for gas leaks.

 

 

Only wrap the gas line side of the insulation for fitting (union)
with the sealing pad (attached).

 

NOTE

 

When connecting the air conditioning unit to the ducting, a
pressure drop will be created and the evaporator airflow
will be reduced. The maximum external static pressure
may not exceed the following values:

 

1

 

Ceiling slab

Anchor

Long nut or turn-buckle

Ensure that a protective guard is installed in front of the air
outlet to prevent that the fan blades can be touched. The
protection must comply with relevant local and national
regulations. 

All field piping must be installed by a licensed refrigeration
technician and must comply with relevant local and
national regulations.

A liquid line and gas line must be provided between the
condensing and the air conditioning unit.
