Operating the valve stem shutoffs
The digital manifold acts like a conventional two-way manifold with
regard to the refrigerant path: The passages are opened by
opening the valves. The adjacent pressure is measured with valves
closed as well as with them open.
> Open valve: Turn valve positioner counterclockwise.
> Close valve: Turn valve positioner clockwise.
WARNING
Over tightening the valve stem shutoffs may cause:
• Damage to the PTFE seal.
• Mechanical deformation of the valve piston leading to the
PTFE seal falling out.
• Damage to the thread of the threaded spindle and the valve
screw.
• valve knobs to brake.
Lightly tighten the valve knob. Do not use tools to tighten the valve
stem shutoffs.
