Application
Solenoid valves series M are used in general refrigeration
and for original equipment to cut off/activate the refrigerant
flow in a refrigerating plant.
The solenoid valves can be installed in the liquid line, hot gas
line and suction line of a refrigerating unit.

Installation
• Position of plunger tube should be from upright to
horizontal position.
• Arrow on valve body must correspond with flow direction.
• Keep 45 mm distance clear above the valve for
assembly/disassembly of coil.
• Fit solenoid valve so that it is drip proof.
• Solder valves:
Remove cap nut, coil and gaskets before soldering
Max. temperature of valve body: 125 °C.
When soldering, always point flame away from valve
body
When assembling after soldering, fit the coil’s top and
bottom seal rings.
• Flare valves:
When tightening flare nuts grip at wrench flats on the
valve body provided for this purposes
Do not use coil and plunger tube as lever (thin-walled
plunger tube).
When installing direct operated valves with 20 W DC
coil, the flare nut must be tightened in that way that one
flat of the nut is in parallel with the lower surface of the
coil.
• Voltage of coil and network must correspond.
• The flat spade terminals is the earth connection. The
protective conductor must also be connected at the plant.
• Do not energize the coil before assembling on the valve
body.
• All gaskets must be fitted carefully in order to achieve
protection to IP65.
• Tighten fixing screw of connector.
• Constructive modifications at the valve are not allowed.
