11.4.2 PNEUMATIC CONNECTION

Remove protective plugs from the gas connection
threads (thread size G1/4“).

There is the possibility to screw in the tube connec-
tion fittings as well on top as on the side of the pump
head. For this remove protective plugs from the gas
connection threads on the side and screw in these on
top of the pump head.

Accessories like tube connection fittings are screwed
into the connection threads with sealing tape (when
using straight M&C connectors no sealing tape is
necessary). Connection fittings for DN4/6 or DN6/8
are available optionally by M&C.

Connect suction and pressure line. For this loosen
union nut of the compression ring fitting counter clockwise; care must be taken that the union
nut is carefully removed from the fitting body so that the loose clamping ring in the union nut is
not getting lost.

Slide the nut over the hose connection;

Slide the clamping ring with the thicker bulge facing the nut, onto the connection hose;

Attach the hose to the nipple in the threaded support;

Hand-tighten the nut. The hose is now mounted slip-proof and pressure-tight.

Lay suction and pressure line such a way that condensate can not flow into the pump.
12 START UP
Before commissioning, the plant and process-specific safety measures must to be observed !
Please note that the pumps may only be used for the intended purpose.
Specific safety instructions for media being handled must be observed. Before pumping a medium,
the compatibility of materials of pump head, diaphragm and valves with the medium must be checked
(for pump materials: see technical data). The following steps should be carried out before initial start-
up:

The pump must not start against pressure or vacuum.

When switching on the pressure in the suction and pressure lines must be atmospheric. This
must be so even when the pump restarts after the power has been cut off for a short period. At
pump standstill atmospheric pressure in the lines has to be established.

The maximum permissible operating pressure (see technical data chapter 9) must not be
exceeded, even when the flow is restricted.
