2. ABOUT THIS PRODUCT
2.1. Precautions for using R410A refrigerant
The basic installation work procedures are the same as conventional refrigerant (R22)
models.
However, pay careful attention to the following points:
Since the working pressure is 1.6 times higher than that of conventional refrigerant (R22)
models, some of the piping and installation and service tools are special. (See the table
below.)
Especially, when replacing a conventional refrigerant (R22) model with a new refrigerant
R410A model, always replace the conventional piping and flare nuts with the R410A
piping and flare nuts.
Models that use refrigerant R410A have a different charging port thread diameter
to prevent erroneous charging with conventional refrigerant (R22) and for safety.
Therefore, check beforehand. [The charging port thread diameter for R410A is
1/2-20 UNF]
Be more careful that foreign matter (oil, water, etc.) does not enter the piping than with
refrigerant (R22) models. Also, when storing the piping ,securely seal the opening by
pinching, taping, etc.
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 where refrigerant
composition is stable.
