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.

Max. ambient temperature: 60 °C (140 °F)
Min. ambient temperature: -40 °C (-40 °F)

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.
