PNEUMATIC

•
Remove the protection plugs from the port threads (thread size G 1/4").
•
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.
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.
Note
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.

SUPPLY LINE CONNECTIONS

15.1

HOSE-/TUBE CONNECTIONS

The gas inlet and outlet hoses/tubes are connected on the top of the pump. Standard G 1/4" threaded joints are
available for the connection of the gas sample lines.
The valve body must be fixed while mounting the fittings because moving may
change the pump capacity. Do not confuse hose-/tube connections for sample gas in-
let and outlet; the connections are labeled accordingly! Check for tightness of all sam-
Note
ple lines after connection!
The tightness of the connections can only be guaranteed if the end section of the con-
nection hose/tube is flat (use a hose-cutter)!
When connecting the sample gas supply hoses or tubes to the corresponding threaded connections, pay attention
to the following points:
•
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.
