12.3.1.1 Check qdos 30 venting screw
A venting screw installation check should be carried out on all qdos 30 pumps prior to the installation of the
pumphead. The venting screw is supplied in the box with all qdos 30 pumpheads.
From January 2020 all qdos 30 pumps have a venting screw pre-installed as standard.
Follow the procedure below to check and install (if necessary) the venting screw.
Procedure
1. Check your pump has the venting screw fitted.
2. If not fitted, remove the venting screw from the pumphead package and install the screw with a flat
blade screwdriver into the location illustrated in the image above.
3. If the venting screw is not fitted in a pump manufactured after January 2020 or you do not have
venting screw contact your Watson-Marlow representative.
!
WARNING
If the venting screw is not fitted, the pump leak detection will not function when process
pressures are less than 1 bar. This could result in fluid leaks from the pumphead being
undetected during operation. Check and, if necessary, install a venting screw prior to
installation of a qdos 30 pumphead.
Do not remove or tamper with the venting screw.
