SPLIT TYPE ROOM AIR CONDITIONER
INSTALLATION MANUAL
(PART NO. 9312365012-01)
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.

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
expansion 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.
mixing of other refrigerants, the diameter of each port has been changed.
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.
To increase pressure resistance, the hose material and base size were changed.
A conventional vacuum pump can be used by installing a vacuum pump adapter.

AIR PURGE
Always use a vacuum pump to purge the air.
Refrigerant for purging the air is not charged in the
outdoor unit at the factory.
Close the high pressure side valve of the gauge manifold fully and do
not operate it during the following work.
1. Check if the piping connections are secure.
2. Check that the stems of 2-way valve and 3-way valve are closed
fully.
3. Connect the gauge manifold charge hose to the charging port
of the 3-way valve (side with the projection for pushing in the
valve core).
4. Open the low pressure side valve of the gauge manifold fully.
5. Operate the vacuum pump and start pump down.
6. Slowly loosen the flare nut of the 3-way valve and check if air
enters, then retighten the flare nut.
(When the flare nut is loosened the operating sound of the
vacuum pump changes and the reading of the compound
pressure gauge goes from minus to zero.)
7. Pump down the system for at least 15 minutes, then check if the
compound pressure gauge reads -0.1 MPa (-76 cmHg, -1 bar).
8. At the end of pump down, close the low pressure side gauge of
the gauge manifold fully and stop the vacuum pump.
9. Slowly loosen the valve stem of the 3-way valve. When the
compound pressure gauge reading reaches 0.1-0.2 MPa,
retighten the valve stem and disconnect the charge hose
from the 3-way valve charging port.
(If the stem of the 3-way valve is opened fully before the
charge hose is disconnected, it may be difficult to disconnect
the charge hose.)
