5. OPERATION DETAILS
Do not purge the air with refrigerants but use a vacuum
pump to vacuum the installation! There is no extra re-
frigerant in the outdoor unit for air purging!
Use a vacuum pump for R407C exclusively. Using the
same vacuum pump for different refrigerant may dam-
age the vacuum pump or the unit.
When moving and installing the air conditioner, do not
mix gas other than the specified refrigerant R407C
inside the refrigerant circuit.
When charging the refrigerant R407C, always use an
electronic balance for refrigerant charging (to measure
the refrigerant by weight).
When charging the refrigerant,
take into account the slight change
in the composition of the gas and
liquid phases, and always charge
from the liquid phase side whose
composition is stable.
Add refrigerant from the charging valve after the
completion of the work.
Use a brand-new refrigerant piping when replacing the
air conditioner using the refrigerant except R407C and
R410A.
