11-3. Tools Specifically for R410A

For servicing, use the following tools for R410A

Tool Distinction

Tool Name

 

 

 

Gauge manifold

 

Charging hose

 

Gas leak detector

 

Refrigerant cylinder

 

Charging cylinder

 

Refrigerant recovery unit

Tools specifically for R410A

Vacuum pump with anti-reverse flow ( 1)

 

(Solenoid valve-installed type, which prevents oil from flowing back into the

 

unit when the power is off, is recommended.)

 

Vacuum pump ( 2) … can be used if the following adapter is attached.

 

Vacuum pump adapter (reverse-flow prevention adapter) ( 3).

 

(Solenoid valve-installed adapter attached to a conventional vacuum pump.)

 

Electronic scale for charging refrigerant

 

Flare tool

 

 

 

Bender

Tools which can be com-

Torque wrench

monly used for R22,

Cutter, reamer

R407C, and R410A

Welding machine, nitrogen gas cylinder

 

 

 

CAUTION

The above tools specifically for R410A must not be used for R22 and R407C. Doing so will cause malfunction of the unit.

For the above vacuum pump (1, 2) and vacuum pump adapter (3), those for R22-type units can be used for R407C-type. However, they must be used exclu- sively for R410A and never alternately with R22 and R407C.

To prevent other refrigerants (R22, R407C) from being mistakenly charged to this unit, sizes of the service ports and flare nuts of the narrow tube service valve and wide tube service valve have been altered.
