10.3 PNEUMATIC
 Remove the protection plugs from the port threads (thread size G1/8“).

Accessories like hose connections are screwed into the port threads by sealing tape (using M&C
connectors sealing tape is not necessary).

Connect the suction and pressure lines.

Arrange the suction and pressure lines so that condensate cannot run into the pump.
N O T E !
The pump must only be used in the conditions specified in the technical
data.
The pump should be installed away from heat sources and freely ventilated
to prevent any accumulation of heat.
For outdoor installation, the pump must be installed in a housing protected
from frost in the winter and sufficiently ventilated in summer. Exposure to
direct sunlight must be avoided.
11 SUPPLY LINE CONNECTIONS
11.1 HOSE-/TUBE CONNECTIONS
The gas inlet and outlet hoses/tubes are connected on the top of the pump. Standard G 1/8" threaded
joints are available for the connection of the gas sample lines.
The appropriate tube or hose threaded joint connections are available optionally from M&C.
N O T E !
Do not confuse hose-/tube connections for sample gas inlet and outlet; the
connections are labelled accordingly !
Check for tightness of all sample lines after connection (see 11.2) !
When connecting the sample gas supply hoses or tubes to the corresponding threaded connections,
pay attention to the following points:
N O T E !
The tightness of the connections can only be guaranteed if the end section
of the connection hose/tube is flat (use a hose-cutter) !

Loosen the sleeve nut of the clamping-ring threaded joint by turning to the left. Take care that the
nut is removed carefully from the body of the threaded joint to avoid losing the clamping ring which
is mounted loose in the nut.

Push the sleeve nut over the connection hose/tube.

Push the clamping ring onto the connection hose/tube with the thicker bulge pointing to nut.

Push the hose/tube onto the supporting nipple in the threaded joint.

Tighten the sleeve nut by hand.
The hose/tube is now mounted in such a way that it cannot slip and is resistant to pressure.
