Flaring Tool
! "
* The flaring tools for R407C are applicable to R22. Flaring for Tubes
* If using flaring tube, make dimension of tube
larger for R410A.
* In case of material 1/2H, flaring is not available.
Pipe Bender
" "
* In case of material 1/2H, bending is not available.
Use elbow for bend and braze.

* Strict Control against Contamin
(Blow nitrogen during brazing.)
Prevention from
Oxidation during
Brazing
Lubrication Oil
(for Flare Surface)
* Use a synthetic oil which is equivalent to the oil
used in the refrigeration cycle.
Applying Oil to the
Flared Surface
* Synthetic oil absorbs moisture quickly.
* Check refrigerant cylinder color. Refrigerant Charging

Do not use current ones to the different refrigerant.
If used, mineral oil will flow into the cycle and cause
sludges, resulting in clogging or compressor failure.
Connection diameter is different; R410A: UNF1/2,
R407C: UNF7/16.
