Watson-Marlow qdos30 PROFIBUS Pump User Manual 61
Hose barbs
• Detach the desired connector from the sprue (2).
• Place user connection collar over the chosen fitting and tighten onto the pumphead (2a).
• Press tube onto connector until it reaches the back face.
• Secure with suitable retaining clip.
Threaded connectors
• Detach the desired connector from the sprue (3).
• Place user connection collar over the chosen fitting and tighten onto the pumphead
(3a) and (3b).
• When attaching the mating thread, restrain the connector using a 14mm spanner
for the 1/4” BSPT (3a) and 9/16” spanner for the 1/4” NPT (3b).
Note: It may be necessary to use a thread sealing tape to get a leak-proof seal.
Compression fittings
• Select the correct compression fittings for the size of tube using the markings on
the sprue and detach both the relevant parts (4).
• Cut the end of the tubing so that it is square (4a) and (4b) not (4e).
• Slide the user connection collar onto the tube.
• Slide the compression ring onto the tube ensuring the inner step is facing the
cut end. See (4a) and (4b) in the diagram on the previous page for correct
orientation not (4c) or (4d).
• Press the tube onto the cone until it reaches the back face (4a) and (4b) not (4f)
(it may be necessary to widen the end of the tube).
• Whilst continuing to hold the tube against the back face of the cone, slide the
compression ring and user connection collar back down the tube and tighten onto
the pumphead (4a) and (4b).
The pump is now ready for use.
Fluid overflow
• When a leak is detected, the leak detection sensor will stop the pump. In the
unlikely event of a sensor failure, the safety overflow provides a safe leak path
for the mixture of the fluid and lubricant to be removed.
• The user is responsible for ensuring that this overflow is connected to a compatible
vented storage container to contain the waste fluid.
