• 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:

• 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.
• 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.

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.

• Be sure to fix the power cables and communication cable
with a cable clamp.
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.
