Note 1 When flaring is carried out for R410A or R32 using the conventional flare tools, adjustment of
projection margin is necessary. For this adjustment, a copper pipe gauge,
etc. are necessary.
Note 2 When saturation temperature is described, the gauge manifold differs for R410A and R32.
If saturation temperature reading is required, special tools exclusive for R32 are required.
Note 3 Since R32 has a slight possibility of burning, be sure to use the tools corresponding to R32.
Note 4 Like R410, a Vacuum pump adapter needs installing to prevent a Vacuum pump oil (mineral oil) from
flowing backward into the Charge hose. Mixing of the Vacuum pump oil into R32 refrigerant may
cause a trouble such as generation of sludge, clogging of capillary, etc.
Note 5 Be sure to use those tools after confirming they correspond to each refrigerant.
Note 6 For a refrigerant cylinder exclusive for R32, the paint color (or label color) of the cylinder is set
the specified color (light blue) together with the indication of the refrigerant name.
Note 7
Although the container specification is the same as R410A, use a recovering container exclusive
for R32 to avoid mixing with other refrigerants.
Note 8 Be careful for miss-charging of the refrigerant during work. Miss-charging of the refrigerant type
may cause not only damage of the equipments but also a fire etc.
In addition to the above exclusive tools, the following equipments are necessary as the general tools.
6) Spanner or Monkey wrench
7) Hole core drill
8) Tape meas
