4. Tools

Tools exclusive for R410A (The following tools for R410A are required.)

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.
