enter the pipe during work).
After evacuating the system for 2 hours, pressurize the system to 0.05 MPa (vacuum break) with nitrogen
gas and evacuate the system again using the vacuum pump for 1 hour to –100.7 kPa (vacuum drying). If
the system cannot be evacuated to –100.7 kPa within 2 hours, repeat the operation of vacuum break and
vacuum drying.
Then, after leaving the system in vacuum for 1 hour, confirm that the vacuum gauge does not rise.
If the indoor unit is changed by another indoor unit, do the above described leaktest again.
1.3
Additional Refrigerant Charge
Refrigerant cannot be charged until field wiring has been completed.
Refrigerant may only be charged after performing the leak test and the vacuum drying (see above).
When charging a system, care shall be taken that its maximum permissible charge is never exceeded,
in view of the danger of liquid hammer.
Charging with an unsuitable substance may cause explosions and accidents, so always ensure that the
appropriate refrigerant (R-410A) is charged for outdoor unit, use (R-134a) for indoor unit.
Refrigerant containers shall be opened slowly.
Always use protective gloves and protect your eyes when charging refrigerant.
When performing service on the unit requiring the refrigerant system to be opened, refrigerant must
be evacuated according to local regulations.
When the power is on, please close the front panel when leaving the unit.
To avoid compressor breakdown. Do not charge the refrigerant more than the specified amount.
This outdoor unit is factory charged with refrigerant and depending on pipe sizes and pipe lengths
some systems require additional charging of refrigerant.
In case re-charge is required, refer to the nameplate of the unit. The nameplate states the type of
refrigerant and necessary amount.
Precautions when recharging/adding R-410A & recharging R-134a
Be sure to charge the specified amount of refrigerant in liquid state to the liquid pipe.
Since this refrigerant is a mixed refrigerant, adding it in gas form may cause the refrigerant composition
to change, preventing normal operation.
Before charging, check whether the refrigerant cylinder is equipped with a siphon tube or not.
Filling using a cylinder with a syphon attached.
Remark for R-134a:
Never recharge more than mentioned on factory name plate.
Charge the liquid
refrigerant with the cylinder
in upright position.
Charge the liquid
refrigerant with the cylinder
in up-side-down position.
