The operating pressure of R32 is higher
than that of R22 (approx. 1.6 times).
It is therefore necessary to firmly tighten
the flare pipe connecting sections (which
connect the indoor and outdoor units)
up to the specified tightening torque.
Incorrect connections may cause not only
a gas leakage, but also damage to the
refrigeration cycle.

Evacuating
After the piping has been connected to the indoor unit, you can perform the
air purge together at once.
AIR PURGE
Evacuate the air in the connecting pipes and in the indoor unit using a
vacuum pump.
Do not use the refrigerant in the outdoor unit.
For details, see the manual of the vacuum pump.
Using a vacuum pump
Be sure to use a vacuum pump with counter-flow prevention function
so that inside oil of the pump does not flow backward into pipes of the
air conditioner when the pump stops. (If oil inside of the vacuum pump
enters the air conditioner, which use R32, refrigeration cycle trouble may
result.)
1. Connect the charge hose from the manifold valve to the service port of
the packed valve at gas side.
2. Connect the charge hose to the port of the vacuum pump.
3. Open fully the low pressure side handle of the gauge manifold valve.
4. Operate the vacuum pump to start evacuating. Perform evacuating
for about 15 minutes if the piping length is 20 meters. (15 minutes
for 20 meters) (assuming a pump capacity of 27 liters per minute)
Then confirm that the compound pressure gauge reading is
–101 kPa (–76 cmHg).
5. Close the low pressure side valve handle of the gauge manifold valve.
6. Open fully the valve stem of the packed valves (both gas and liquid
sides).
7. Remove the charging hose from the service port.
8. Securely tighten the caps on the packed valves.

Existing Piping
Work instructions
The existing R22 and R410A piping can be reused for
inverter R32 product installations.
WARNING
• Confirming the existence of scratches or dents on the
existing pipes and confirming the reliability of the pipe
strength are conventionally referred to the local site.
• If the specified conditions can be cleared, it is possible
to update existing R22 and R410A pipes to those for
R32 models.
Basic conditions needed to reuse existing
pipes
Check and observe the presence of three conditions in the
refrigerant piping works.
1. Dry (There is no moisture inside of the pipes.)
2. Clean (There is no dust inside of the pipes.)
3. Tight (There are no refrigerant leaks.)
Restrictions for use of existing pipes
In the following cases, the existing pipes should not
be reused as they are. Clean the existing pipes or
exchange them with new pipes.
1. When a scratch or dent is heavy, be sure to use new
pipes for the refrigerant piping works.
2. When the existing pipe thickness is thinner than the
specified “Pipe diameter and thickness,” be sure to use
new pipes for the refrigerant piping works.
• The operating pressure of R32 is high (1.6 times that
of R22). If there is a scratch or dent on the pipe or a
thinner pipe is used, the pressure strength may be
inadequate, which may cause the pipe to break in the
worst case.

There is the possibility that moisture has mixed with
the oil and rust has been generated inside the pipe.
• There is discolored oil, a large quantity of residue,
or a bad smell.
• A large quantity of shiny metal dust or other wear
residue can be seen in the refrigerant oil.
7. When the air conditioner has a history of the compressor
failing and being replaced.
• When discolored oil, a large quantity of residue,
shiny metal dust, or other wear residue or mixture of
foreign matter is observed, trouble will occur.
8. When temporary installation and removal of the
air conditioner are repeated such as when leased etc.
9. If the type of refrigerator oil of the existing air conditioner
is other than the following oil (Mineral oil), Suniso,
Freol-S, MS (Synthetic oil), alkyl benzene
(HAB, Barrel-freeze), ester series, PVE only of ether
series.
• The winding-insulation of the compressor may
deteriorate.
NOTE
• The above descriptions are results have been confirmed
