This air conditioner uses new refrigerant HFC (R410A).

The basic installation work procedures are the same as conventional refrigerant (R22) models.

However, pay careful attention to the following points:

(1) Since the working pressure is 1.6 times higher than that of conventional refrigerant(R22) mod-

els, some of the piping and installation and service tools are special.(See the table below.)

ENGLISH

Especially, when replacing a conventional refrigerant(R22) model with a new refrigerant R410A

model, always replace the conventional piping and flare nuts with the R410A piping and flare

nuts.

(2) Models that use refrigerant R410A have a different charging port thread diameter to prevent

erroneous charging with conventional refrigerant(R22) and for safety. Therefore, check

beforehand.[The charging port thread diameter for R410A is 1/2 threads per inch.]

(3) Be more careful that foreign matter (oil, water, etc.) does not enter the piping than with

refrigerant(R22) models. Also, when storing the piping ,securely seal the opening by pinching,

taping, etc.

(4) When charging the refrigerant, take into account the slight change in the composition of the

gas and liquid phases, and always charge from the liquid phase side whose composition is

stable.

Special tools for R410A

Tool name

Contents of change

Pressure is high and cannot be measured with a conventional gauge. To prevent erroneous

mixing of other refrigerants, the diameter of each port has been changed.

Gauge manifold

It is recommended the gauge with seals-0.1 to 5.3 MPa (-1 to 53 bar) for high pressure.

-0.1 to 3.8 MPa (-1 to 38 bar) for low pressure.

Charge hose

To increase pressure resistance, the hose material and base size were changed.

Vacuum pump

A conventional vacuum pump can be used by installing a vacuum pump adapter.

Special gas leakage detector for HFC refrigerant R410A.

As an air conditioner using R410A incurs pressure higher than

when using R22, it is necessary to choose adequate materials.

Thicknesses of copper pipes used with R410A are as shown in the table. Never use copper pipes thinner than that in the

table even when it is available on the market.

WARNING

(1) Do not use the existing (for R22) piping and flare nuts.

• If the existing materials are used, the pressure inside the refrigerant cycle will rise and cause breakage, injury,

etc.(Use the special R410A materials.)

(2) When installing and relocating the air conditioner, do not mix gases other than the specified refrigerant(R410A) to

enter the refrigerant cycle.

• If air or other gas enters the refrigerant cycle, the pressure inside the cycle will rise to an abnormally high value

and cause breakage, injury, etc.

CAUTION

When installing pipes shorter than 17ft (5m), sound of the outdoor unit will be transferred to the indoor unit, which

will cause large operating sound or some abnormal sound.

SELECTING THE MOUNTING

INSTALLATION DIAGRAM OF

INDOOR AND OUTDOOR UNITS

POSITION

Decide the mounting position with the customer as follows:

[INDOOR UNIT]

1. INDOOR UNIT

(1) Install the indoor unit level on a strong wall which is not subject

2"(5 cm) or over

to vibration.

(2) The inlet and outlet ports should not be obstructed : the air should

be able to blow all over the room.

(3) Install the unit near an electric outlet or special branch circuit.

(4) Do not install the unit where it will be exposed to direct sunlight.

(5) Install the unit where connection to the outdoor unit is easy.

(6) Install the unit where the drain pipe can be easily installed.

(7) Take servicing, etc. into consideration and leave the spaces shown

in the figure. Also install the unit where the filter can be removed.

60"(150 cm)

2. OUTDOOR UNIT

or over

(1) If possible, do not install the unit where it will be exposed to di-

rect sunlight. (If necessary, install a blind that does not interfere

with the air flow.)

(2) Do not install the unit where a strong wind blows or where it is

very dusty.

(3) Do not install the unit where people pass.

(4) Take your neighbors into consideration so that they are not dis-

turbed by air blowing into their windows or by noise.

(5) Provide the space shown in the figure so that the air flow is not blocked.

Also for efficient operation, leave open three of the four direc-

tions front, rear, and both sides.

[OUTDOOR UNIT]

WARNING

Install at a place that can withstand the weight of the

indoor and outdoor units and install positively so that

the units will not topple or fall.

4"(10 cm) or over

CAUTION

(1) Do not install where there is the danger of com-

bustible gas leakage.

(2) Do not install near heat sources.

(3) If children under 10 years old may approach the

unit, take preventive measures so that they can-

will cause failure.

(4) Install the indoor unit on the wall where the height

from the floors more than 240 cm.

Q'ty

[Indoor unit piping direction]

The piping can be connected in the 7 directions in the figure. When

the piping is connected in direction 2, 3, 4 or 5, cut along the

piping groove in the side of the front panel with a hacksaw.

(Rear)

In the area with heavy snowfall, if the intake and outlet of outdoor unit is

blocked with snow it is likely to cause of the breakdown. Please con-

struct a canopy and a pedestal or place the unit on a high stand (local

configured).

CUTTING THE HOLE IN THE WALL FOR THE CONNECTING PIPING

(1) Cut a 3-1/8"(80 mm) diameter hole in the wall at the position shown in

the figure.

(2) When cutting the wall hole at the inside of the wall hook bracket, cut

the hole to a point of intersection of center marks.

When cutting the wall hole at the outside of the wall hook bracket, cut

the hole at a point of 10mm below.

(3) Cut the hole so that the outside end is lower (3/16" to 3/8" (5 to 10

mm)) than the inside end.

(4) Always align the center of the wall hole. If misaligned, water leakage

will occur.

(5) Cut the wall pipe to match the wall thickness, stick it into the wall cap,

fasten the cap with vinyl tape, and stick the pipe through the hole. (The

connection pipe is supplied in the installation set.)

(6) For left piping and right piping, cut the hole a little lower so that drain

water will flow freely.

INSTALLING THE WALL HOOK BRACKET

(1) Install the wall hook bracket so that it is correctly positioned horizon-

tally and vertically. If the wall hook bracket is tiled, water will drip to the

floor.

(2) Install the wall hook bracket so that it is strong enough to withstand

the weight of an adult.

Fasten the wall hook bracket to the wall with 6 or more screws through

the holes near the outer edge of the bracket.

Check that there is no rattle at the wall hook bracket.

WARNING

If the wall pipe is not used, the cord interconnecting

the indoor and outdoor units may touch metal and

cause electric leakage.

FORMING THE DRAIN HOSE AND PIPE

[Rear piping, Right piping, Bottom piping]

Install the indoor unit piping in the direction of the wall hole and bind

the drain hose and pipe together with vinyl tape.

Install the piping so that the drain hose is at the bottom.

Wrap the pipes of the indoor unit that are visible from the outside with

CAUTION

(1) In order to align the drain hose and drain cap, be

sure to insert securely and vertically. Incline inser-

tion will cause water leakage.

(2) When inserting, be sure not to attach any mate-

rial besides water. If any other material is attached,

it will cause deterioration and water leakage.

(3) After removing drain hose, be sure not to forget

mounting drain cap.

(4) Be sure to fix the drain hose with tape to the bottom

of piping.

(5) Prevent drain water frozen under low temperature

environment.

When installing indoor unit's drain hose outdoors, necessary

measure for frost protection should be taken to prevent drain

water frozen.

• Under low temperature environment (when outdoor tempera-

ture under 32 °F), after cooling operation is executed, water in

the drain hose could be frozen.

Once drain water is frozen, the drain hose will be blocked

and water leakage may be resulted for indoor unit.

(2) During installation, make sure that the refrigerant pipe is attached firmly

before you run the compressor. Do not operate the compressor under the

condition of refrigerant piping not attached properly with 3-way valve open.

This may cause abnormal pressure in the refrigeration cycle that leads to

breakage and even injury.
