7.1 Preparing for measurement
7.1.1 Operating the valve positioners
With respect to the refrigerant path, the digital manifold behaves just like a
conventional four-way manifold: The passages are opened by opening the
valves. The applied pressure is measured with the valves closed and the valves
opened.
-
Open the valve: Turn valve positioner anticlockwise.
-
Close the valve: Turn valve positioner clockwise.
WARNING
Valve positioner tightened too tightly.
• Damage to the PTFE seal (1).
• Mechanical deformation of the valve
piston (2) leading to the PTFE seal (1)
falling out.
• Damage to the thread of the threaded
spindle (3) and the valve screw (4).
Broken valve knob (5).
Only tighten the valve positioner hand-tight.
Do not use any tools to tighten the valve
positioners.
