Tightening torque of flare pipe connections
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.
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.

APPENDIX
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.
* Pipe diameter and thickness (mm)

3. When the outdoor unit was left with the pipes
disconnected, or the gas leaked from the pipes and the pipes were not repaired and refilled.
There is the possibility of rain water or air, including
moisture, entering the pipe.
4. When refrigerant cannot be recovered using a
refrigerant recovery unit.
There is the possibility that a large quantity of dirty
oil or moisture remains inside the pipes.
5. When a commercially available dryer is attached to the
existing pipes.
There is the possibility that copper green rust has
been generated.
6. When the existing air conditioner is removed after
refrigerant has been recovered.
Check if the oil is judged to be clearly different from
normal oil.
The refrigerator oil is copper rust green in color:
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 by our company and represent our views on our air conditioners, but do not guarantee the use of the existing pipes of air conditioners that have adopted R32 in other companies.
Curing of pipes When removing and opening the indoor or outdoor unit for a long time, cure the pipes as follows:
Otherwise rust may be generated when moisture or
foreign matter due to condensation enters the pipes.
The rust cannot be removed by cleaning, and new
pipes are necessary.
Placement
location Term Curing manner
Outdoors 1 month or more Pinching
Less than 1 month Pinching or taping
Indoors Every time
Are there scratches or dents on the existing pipes?
Is it possible to operate the existing air conditioner?
After the existing air conditioner is operated in cooling
mode for approx. 30 minutes or longer,* recover the refrigerant.
For cleaning the pipes and recovering oil
Refrigerant recovery: Pump down method
Remove the existing air conditioner from the piping
and carry out flushing (nitrogen pressure 0.5 MPa) to remove any remains inside of the pipe.
Note: In case of twin pipes, also be sure to flush the
branching pipe.
Connect the indoor / outdoor units to the existing pipe.
Use a flare nut attached to the main unit for the indoor
/ outdoor units. (Do not use the flare nut of the existing pipe.)
Re-machine the flare machining size to size for R32.

Använd inget annat köldmedium än det som specifi ceras för påfyllning eller
utbyte.
Fel typ av köldmedium kan ge upphov till ett onormalt högt tryck i kylcykeln,
vilket kan resultera i att produkten går sönder eller exploderar med eventuell
personskada som följd.
Använd inte några andra sätt att påskynda avfrostningsprocessen eller för att
rengöra än de som rekommenderas av tillverkaren.
Apparaten ska förvaras i ett rum utan konstant drivna antändningskällor (t.ex.:
öppna flammor, en gasapparat i drift eller en elvärmare i drift).
Var medveten om att köldmedium kanske inte innehåller någon lukt.
Gör inte hål på eller bränn eftersom apparaten är försedd med tryck. Utsätt inte
apparaten för hetta, flammor, gnistor, eller andra antändningskällor. Den kan i så
fall explodera och orsaka personskada eller dödsfall.
För modell R32, använd rörledning, flänsmutter och verktyg som specificerats
för R32-köldmedium. Användning av befintlig (R22) rörledning, flänsmutter
och befintliga verktyg kan orsaka onormalt högt tryck i köldmediesystemet
