Installation
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 (for
✴✴18/24✴✴) 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
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.
