*1 Those testers only for HCFC22 (R22), but not for HCF32 (R32) and HCF410A (R410A) cannot be for common use.
*2 Recovery devices which are self-certified for each HCF type can be used.
[Knowledge for the common usage of tools for R410A & R32]

R410A and R32 machines use different compressor oils.

If unregulated compressor oil gets mixed into, it may cause damage to the machine function.

Careful pump down will ensure the recovery of compressor oil, and it will minimize the remaining amount of the oil in the manifold
gauge and charging hose.

If you only perform the recovery of refrigerant and not be able to perform pump down, you have to dispose the compressor oil in
the charging hose.
[Precaution of repairing refrigerant cycle]

In the brazing, open 2-way and 3way valves, and make sure the refrigerant is completely recovered back and not remaining the
system.

When repairing outside, make sure no refrigerant is in the air, ensure good air flow, and perform the brazing.
[Inserting wrong refrigerant]

It may cause “not cooling” and “not heating” customer claims because each component (expansion valve, compressor, PCB) of the
refrigeration cycle is specially adjusted for R32.

At the same time, it is not subject to product warranty, if wrong refrigerant was inserted into the system.
