Required Tools for
R32 or
R410A
Mixing of different types of oil may cause a trouble such as generation of sludge, clogging of capillary,
etc. Accordingly, the tools to be used are classified into the following three types.
1)
Tools exclusive for
R32 or
R410A (Those which cannot be used for conventional refrigerant (R22))
2)
Tools exclusive for
R32 or
R410A, but can be also used for conventional refrigerant (R22)
3)
Tools commonly used for
R32 or
R410A and for conventional refrigerant (R22)
The table below shows the tools exclusive for
R32 or
R410A and their interchangeability.
Tools exclusive for
R32 or
R410A (The following tools for R410A are required.)
Tools whose specifications are changed for
R32 or
R410A and their interchangeability
(Note)
When flaring is carried out for
R32 or
R410A using the conventional flare tools, adjustment of
projection margin is necessary. For this adjustment, a copper pipe gauge, etc. are necessary.
General tools (Conventional tools can be used.)
In addition to the above exclusive tools, the following equipments which serve also for R22 are necessary
as the general tools.
