Installation Procedure
Charging the system with liquid refrigerant
R-410A is a mixed type of refrigerant. It is necessary
for recharging under conditions of liquid. When
charging refrigerant from the refrigerant cylinder to the
equipment, follow the instructions below.
• Before charging, check whether the cylinder has a
siphon or not. There are two ways to recharge the
refrigerant.
Cylinder with siphon Cylinder without siphon
siphon
Charge the refrigerant standing
the cylinder upright.
Charge the refrigerant turning
the cylinder upside down.
NOTE
• If R-410A refrigerant is charged as a gas, the
composition of the charged refrigerant changes and
the characteristics of the equipment vary.
• While adding refrigerant, use an electronic scale to
measure the volume added. If the refrigerant cylinder
doesn’t have a siphon, turn it upside-down.
Step 10 Draining the water naturally
When using the air conditioner in the heating mode, ice
may accumulate. During de-icing (defrost operation), the
defrosting water must be drained off safely.
• Do not install a drain hose, a drain plug and a cap. (Let
the water drain naturally).
• Ice may form on the ground. Take appropriate
measures to prevent ice formation.

Step 11 Insulating the refrigerant
pipes
1 Once you have checked that there are no leaks in the
system, you can insulate the piping and hose.
No gap
Insulation
NOTE
• When insulating the pipe, be sure to overlap the
insulation.
• Use insulation with the appropriate specifications
to conform to all national, state, and local codes and
regulations. Refer to the following page for minimum
performance properties of the insulation.
CAUTION
• When insulating the pipe, use non-slit insulator.
