and Attention (*: Strictly Required)
✧ ✧
* The flaring tools for R32 are applicable to
R22/R410A.
* If using flaring tube, make dimension of
✧ ✧
tube larger for R410A.
* In case of material 1/2H, flaring is not
available.
* In case of material 1/2H, bending is not
✧ ✧
available. Use elbow for bend and braze.
* In case of material 1/2H, expanding of tube
is not available. Use socket for connecting
✧ ✧
tube.
× ✕ * For φ1/2, φ5/8, spanner size is up 2mm.
✧
* Forφ1/4, φ3/8, φ3/4, spanner size is the
✧ ✧
same.
* Perform correct brazing work.
✧ ✧
* Strict Control against Contamin (Blow
✧ ✧
nitrogen during brazing.)
* Use a synthetic oil which is equivalent to
✦
●
the oil used in the refrigeration cycle.
* Synthetic oil absorbs moisture quickly.
* Check refrigerant cylinder color.
* Liquid refrigerant charging is required
✕ ✕
regarding zeotoropic refrigerant.
* Use the weight scale.
* The current ones are applicable. However,
✧ ✧
it is required to mount a vacuum pump
adapter which can prevent from reverse flow
when a vacuum pump stops, resulting in no
✧ ✦
reverse oil flow.
* No interchangeability is available due to
higher pressures when compared with R22.
* 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;
R32/R410A: UNF1/2, R22: UNF7/16.
