SPLIT TYPE ROOM AIR CONDITIONER

INSTALLATION MANUAL

(PART No. 9378533011)

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) models,

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

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

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.

Gas leakage detector

Copper pipes

It is necessary to use seamless copper pipes and it is desirable

that the amount of residual oil is less than 40 mg/10m. Do not

use copper pipes having a collapsed, deformed or discolored

portion (especially on the interior surface). Otherwise, the ex-

pansion value or capillary tube may become blocked with

contaminants.

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 Table1.Never us copper pipes thinner than 0.8mm even

when it is available on the market.

(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.

When installing pipes shorter than 3m, 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

POSITION

Decide the mounting position with the customer as follows:

(1) Install the indoor unit level on a strong wall which is not subject 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 (Fig. 1). Also install the unit where the filter can be removed.

(8) Install the place where is no gap around the unit.

WARNING

Install at a place that can withstand the weight of the

indoor and install positively so that the units will not

topple or fall.

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-

not reach the unit.

CUSTOMER GUIDANCE

Explain the following to the customer in accordance with the operat-

ing manual:

(1) Starting and stopping method, operation switching, temperature

adjustment, timer, air flow switching, and other remote control

unit operations.

(2) Air filter removal and cleaning, and how to use the air louvers.

(3) Give the operating and installation manuals to the customer.

EMBEDDING THE INDOOR UNIT IN A WALL

When installing a grating, use a grating with narrow upper and lower

horizontal bars so that the airflow from the upper and lower air outlets

does not contact the bars. If the horizontal bars will block the lower

air outlet, use a stand, etc., to adjust the height of the indoor unit. If

the upper or lower air outlet is blocked, the air conditioner will not be

able to cool or warm the room well.

Do not block the receiver with the grating. Otherwise, the grating will

interfere with the remote controller signal and significantly reduce

the distance and area (angle) from which the signals can be received.

Use a grating with vertical bars, etc., that has at least 75% open area.

If the grating has horizontal bars or if the open area is less than 75%,

performance could be reduced.

When the indoor unit is embedded in a wall (built-in), the time it takes

for the room temperature to reach the set temperature will increase.

[Indoor unit piping direction]

The piping can be connected in the six directions indicated by 1,

2, 3, 4, 5and 6 in (Fig. 2). When the piping is connected in

direction 2 or 5, cut along the piping groove in the side of the

base with a hacksaw.

When connecting the piping in direction 3, 6cut a notch in the thin

wall at the front bottom of the base.
