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.
installation
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.

Liquid service port <High pressure>
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 15g of
refrigerant R-410A for each extra metre. 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 of 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,
take the following instructions:
Before recharging, check whether the cylinder has
a siphon or not. There are two ways to recharge the
refrigerant:
Siphon
Charge the refrigerant turning
Charge the refrigerant
the cylinder upside down.
standing the cylinder upright.
<Cylinder with siphon> <Cylinder without siphon>
NOTE
• If R-410A refrigerant is charged with gas, the
composition of the charged refrigerant changes and
the characteristics of the equipment vary.
installation
• During the measuring operation of refrigerant quantity
added, use electronic scales. If cylinder doesn't have
siphon, upset it.
