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 to
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 measure
9) Metal saw
1) Pipe cutter
2) Reamer
3) Pipe bender
4) Level vial
5) Screwdriver (+, –)
Also prepare the following equipments for other installation method and run check.
1) Clamp meter
2) Thermometer
3) Insulation resistance tester (Megger)
4) Electroscope
