Mounting |
|
|
|
|
|
|
|
The valve has to be 100% open when mounting - as delivered. |
||
|
|
|
The valve must be supported with tube supporters either on |
||
|
|
|
the valve itself or on the tubes connected to the valve. The valve |
||
|
|
|
must not be exposed to any external influence like shock or |
||
|
|
|
punches. |
|
|
|
|
|
A filter with a maximum mesh of 100 μm is required on the inlet |
||
|
|
|
line if the refrigerant contains particles above 100 μm. |
||
|
Welding |
|
|
|
|
Only allowed when there is no explosion danger. Always ensure that there is no R290 present in the pipes and in the surroundings.
To braze the parts they must be cleaned mechanically or chemically, and after assembly add flux. Heat the parts by placing the heat most to the part with the best heat transfer. In this case the tube. When the parts are on brazing temperature add brazing material.
Materials used for brazing:
Flus: Metalli tenacity No. 5 Powder or Braze Tec special h paste. Filler: Silver-Flo 55 (BS:AG 14/ DIN L-Ag55 Sn) or Silver-Flo 56 (AWS B Ag-7).
Filler metals containing Phosphor i.e. BS: CP 1/ DIN L-Ag 15P or BS: CP 3/ DIN L-Ag P7 must not be used.
