Pump inlet/outlet connections
Arrange the pump inlet and outlet according to a piping system in which the pump is incorporated.
■
Tube connection
Cut the tube ends flat.
NOTE
Otherwise a leak may result.
Pass a tube into the fitting nut and stopper and
then slide it down to the tube adapter as far as
it will go.
NOTE
The tube end must come within at least 2mm from the
bottom of the adapter.
Place an O ring into the inlet/outlet unit (part # 70/71).
Secure the tube end (with the tube adapter) on the inlet/outlet unit by hand-tightening the
fitting nut.
NOTE
The plastic fitting nut may be broken if tightened too much.
■ Union connection
Connect the union socket (72) to a plastic flange or joint of your piping system. Use an adhesive to secure the
connection.
NOTE
Do not allow an extra amount of adhesive to enter the pump.
