9-3. 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

 

 

Tools which can be com-

Bender

Torque wrench

monly used for R22,

Cutter, reamer

R407C, and R410A

Welding tool, 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 R410A-type. However, they must be used exclusively for R410A and never alternately with R22 and R407C.

To prevent other refrigerants (R22, R407C) from being mistakenly charged to this unit, shape and external diameter of the service port screw has been altered.

<External diameter of service port>

R410A : 7.94 mm (5/16")



R22, R407C : 6.35 mm (1/4")

9-4. Tubing Installation Procedures

When the tubes are connected, always apply HAB oil on the flare portions to improve the sealing of tubing. The following is the HAB oil generally used:

Esso: ZERICE S32

NOTE For details on tubing installation procedures, refer to the installation manuals attached to the indoor unit and outdoor unit.
