Step 2.8 Installing and connecting the

assembly pipes to the refrigerant pipes

(assembly pipe)

Connect indoor and outdoor units with field-supplied copper

pipes by means of flare connections. Use insulated seamless

refrigeration grade pipe only, (Cu DHP type according to

ISO1337), degreased and deoxidized, suitable for operating

pressures of at least 4200 kPa and for burst pressure of at

least 20700 kPa. Under no circumstances must sanitary type

copper pipe be used.

There are 2 refrigerant pipes of different diameters:

• The smaller one is for the liquid refrigerant
• The larger one is for the gas refrigerant

A short liquid refrigerant pipe and a short gas refrigerant

pipe are already fitted to the air conditioner. The

connection procedure for the refrigerant pipes varies

according to the exit position of each pipe when facing

the wall:

Right

Underside

Rear right or left

1 Cut out the appropriate knock-out piece (A, B, C) on the

rear of the indoor unit unless you connect the pipe directly

from the rear.

2 Smooth the cut edges.
3 Remove the protection caps of the pipes and connect the

assembly pipe to each pipe. Tighten the nuts first with

your hands, and then with a torque wrench, applying the

following torque:

NOTE

• If you want to shorten or extend the pipes, see Step 2.9

Shortening or extending the refrigerant pipes (assembly

pipe).

4 Cut off the remaining foam insulation.
5 If necessary, bend the pipe to fit along the bottom of the

indoor unit. Then pull it out through the appropriate hole.
• The pipe should not project from the rear of the indoor

unit.

• The bending radius should be 100 mm or more.

6 Pass the pipe through the hole in the wall.

NOTE

• The pipe will be insulated and fixed permanently into

position after finishing the installation and the gas leak

test. For further details. see Step 4.1 Performing the gas

leak tests.

CAUTION

• Tighten the flare nut with a torque wrench according to

specified method. If the flare nut is over-tightened, the flare

may break and cause refrigerant gas leakage.

• Do not box in or cover the pipe connection. All refrigerant

pipe connection must be easily accessible and serviceable.

attention to the weight of the indoor unit.

3 Attach the installation plate to the wooden upright using

tapping screws.

When fixing the indoor unit on a gypsum board

1 Use stud finder to find out locations of the studs.
2 Fix the plate hanger on two studs.

CAUTION

• If you fix the indoor unit on a gypsum board, use only

specified anchor bolts on reference positions. Otherwise,

the gypsum surrounding the joints may crumble over time

and cause the screws to be loosened and stripped. This

may lead to physical injury or equipment damage.

• Search for other spots if there are less than two studs, or

the distance between the studs are different from the plate

hanger.

• Fix the installation plate without inclining to one side.

Step 3.1 Fixing the outdoor unit in

place

Rubber leg

1 Place the outdoor unit as directed on the top of the unit to

let the discharged air out properly.

2 Fix the outdoor unit in level to an appropriate support

using anchor bolts.

NOTE

• Secure the rubber legs to help prevent the generation of

noise and vibration.

• If the outdoor unit is exposed to strong winds, install shield

plates around the outdoor unit so that the fan can operate

correctly.

Optional: Fixing the outdoor unit to a wall with a rack

Step 3.3 Evacuating the air

The outdoor unit is loaded with sufficient R-410A

refrigerant. Do not vent R-410A into atmosphere: it is a

fluorinated greenhouse gas, covered by Kyoto Protocol,

with a Global Warming Potential (GWP) = 2088. You should

evacuate the air in the indoor unit and in the pipe. If air

remains in the refrigerant pipes, it affects the compressor.

It may cause reduction of cooling capacity and malfunction.

Use a vacuum pump.

CAUTION

• When installing, make sure there is no leakage. When

recovering the refrigerant, ground the compressor first

before removing the connection pipe. If the refrigerant

pipe is not properly connected and the compressor

works with the stop valve open, the pipe inhales the air

and it makes the pressure inside of the refrigerant cycle

abnormally high. It may cause explosion and injury.

1 Leave the system in the standby mode.

WARNING

• Do not turn on the system! This is necessary for better

vacuum operation (full OPEN position of Electronic

Expansion Valve).

2 Connect the charging hose of the low pressure side

of manifold gauge to a gas service port as seen in the

picture.

3 Open the valve of the low pressure side of manifold gauge

anticlockwise.

4 Evacuate the air in the connected pipes using the vacuum

pump for about 15 minutes.

• Make sure that pressure gauge shows -0.1 MPa (-76

cmHg, 5 torr) after about 10 minutes. This procedure is

very important to avoid a gas leak.

• Close the valve of the low pressure side of manifold

gauge clockwise.

• Turn off the vacuum pump.
• Check for 2 minutes if there is any pressure change.
• Remove the hose of the low pressure side of manifold

gauge.

5 Set a valve cork of liquid and gas service port to the open

position.

Step 3.4 Adding refrigerant

If you use a pipe longer than the length specified in the

piping codes and standards, you must add 15 g of refrigerant

R-410A for each extra meter. If you use a pipe shorter than

the length specified in the piping codes and standards, the

evacuating time is normal. Refer to the Service Manual for

further details.

CAUTION

• The remaining air in the Refrigeration cycle, which contains

moisture, may cause malfunction on the compressor.

• Always contact the service centre or a professional

installation agency for product installation.

R-410A is a mixed type of refrigerant. It is necessary for

recharging under conditions of liquid. When recharging

refrigerant from the refrigerant cylinder to the equipment.
Before recharging, check whether the cylinder has a siphon

or not. There are two ways to recharge the refrigerant:

Siphon

Charge the refrigerant

standing the cylinder upright.

Charge the refrigerant turning

the cylinder upside down.

NOTE

• If R-410A refrigerant is charged with gas, the composition

of the charged refrigerant changes and the characteristics

of the equipment vary.

• During the measuring operation of refrigerant quantity

added use electronic scales. If cylinder doesn't have siphon,

upset it.

Installation Inspection

Step 4.1 Performing the gas leak tests

1 Before inspecting the leakage, use a torque wrench to

close the cap for the stop valve. (Comply with a tightening

torque for each size of the diameter, and tighten the cap

firmly to prevent any leakage.)

Tightening torque for body cap

Pumping down refrigerant

Pump-down is an operation intended to collect all the

system refrigerant in the outdoor unit. This operation

must be carried out before disconnecting the refrigerant

tubing in order to avoid refrigerant loss to the

atmosphere.

1 Shut off the liquid valve with the Allen wrench.
2 Turn on the air conditioner in cooling with fan operating

at high velocity. (Compressor will immediately start,
provided 3 minutes have elapsed since the last stop.)

3 After 2 minutes of operation, shut the suction valve

with the same wrench.

4 Turn off the air conditioner and switch mains supply off.

5 Disconnect tubing. After disconnection, protect valves
and tubing ends from dust.

CAUTION

• Compressor damage may occur if the compressor is run

at a negative suction pressure.
