Installation
• The valves may be installed in any position.
• The external pressure equaliser line should be 6 mm or
1/4” in diameter. An overbow is recommended in order to
prevent the ingress of oil into the equaliser line.
• When soldering the valve, the valve body must not get
warmer than 100 °C.
• When tightening flare nuts of the flare connections grip at
wrench flats on the valve body.
• Constructive modifications at the valve are not allowed.
Evaporating pressure Adjustment
The evaporating pressure setting can be adjusted by
± 0.5 bar around the range middle of the evaporating
pressure range.
Turning clockwise = reduced evaporating pressure
Turning
counterclockwise
= increased evaporating pressure
Special Accessory:
Adapter series LA for solder connection at the inlet for 6 mm,
10 mm, 1/4” and 3/8”.
