Installation of new refrigerant air conditioner

This air conditioner adopts the new HFC refrigerant (R410A) which does not deplete the ozone layer.
R410A refrigerant is vulnerable to impurities such as water, oxidizing membranes, or oils because the pressure
Usage
of R410A refrigerant is higher than that of the former refrigerant by approximately 1.6 times.
As well as the adoption of the new refrigerant, the refrigerating oil has been also changed. Therefore, pay
attention so that water, dust, former refrigerant, or refrigerating oil does not enter the refrigerating cycle of the
new refrigerant air conditioner during installation.
To prevent mixing of refrigerant or refrigerating oil, the size of the charge port of the main unit or connecting
section of the installation tool differs to that of an air conditioner for the former refrigerant.
Accordingly, exclusive tools are required for the new refrigerant (R410A) as shown below.
For connecting pipes, use new and clean piping materials so that water or dust does not enter.
Required tools and cautions on handling
It is necessary to prepare the tools and parts for installation as described below. The tools and parts which will be
newly prepared in the following items should be restricted to exclusive use.
Explanation of symbols
: Newly prepared (It is necessary to use it exclusively with R410A, separately from those for R22 or R407C.)
: Former tool is available.
