6-3-1. Required Tools

The service port diameter of packed valve of the outdoor unit in the air conditioner using R410A is changed to
prevent mixing of other refrigerant. To reinforce the pressure-resisting strength, flare processing dimensions and
opposite side dimension of flare nut (For Ø12.7 copper pipe) of the refrigerant piping are lengthened.

The used refrigerating oil is changed, and mixing 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 R410A (Those which cannot be used for conventional refrigerant (R22))

(2) Tools exclusive for R410A, but can be also used for conventional refrigerant (R22)

(3) Tools commonly used for R410A and for conventional refrigerant (R22)

The table below shows the tools exclusive for R410A and their interchangeability.

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

(Note 1) When flaring is carried out for R410A using the conventional flare tools, adjustment of projection

margin is necessary. For this adjustment, a copper pipe gauge, etc. are necessary.

(Note 2) Charging cylinder for R410A is being currently developed.

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.

(1) Vacuum pump

Use vacuum pump by
attaching vacuum pump adapter.

(2) Torque wrench

(3) Pipe cutter

(4) Reamer

(5) Pipe bender

(6) Level vial

(7) Screwdriver (+, –)

(8) Spanner or Monkey wrench

(9) Hole core drill (Ø65)

(10) Hexagon wrench

(Opposite side 4mm)

(11) Tape measure

(12) Metal saw

Also prepare the following equipments for other installation method and run check.

(1) Clamp meter

(2) Thermometer
