performance. Close the doors and windows.
Cleaning and Maintenance
• Check whether the air conditioner is turned on immediately after the
cooling operation stops. In this case, only the fan runs to protect the
outdoor unit compressor.
• Check whether the pipe length is too long. When the pipe length exceeds
the maximum pipe length, the cooling performance may decrease.
I cannot change the air
flow direction.
• Check whether the good'sleep function is running. While this function is
running, you cannot control the air flow direction.
I cannot change the fan
speed.
• When the Auto, Dry, or Fast mode is running or the good'sleep function
is running in the Cool mode, the air conditioner controls the fan speed
automatically and you cannot change the fan speed.

Installation
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.

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.
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:
50 English
Siphon
Charge the refrigerant
standing the cylinder upright.
Charge the refrigerant turning
the cylinder upside down.
<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.
• During the measuring operation of refrigerant
quantity added, use electronic scales. If cylinder
doesn't have siphon, upset it.
