It is advisable to use controlled waste pipe work if pumping hazardous, aggressive
or abrasive fluids or products which will harden in contact with air.
When connecting waste pipe work to the controlled waste port using the coupling
adaptor supplied, ensure that there is adequate clearance underneath the
pumphead. Waste pipe work should run to a suitable container or drain.
The leak detector installation procedure is included in the leak detector kit.
If unsure of an installation please contact your local Watson-Marlow Technical
Support Office for further assistance.
620RE, 620RE4 and 620R General operation
Opening the pumphead guard
Unlock the guard with a 5mm Allen key or a screw driver.
Open the guard to its full extent. This creates the maximum clearance between the
tube ports and guard to remove the tubing.
Engaging/disengaging the rollers
The extent of travel of the roller release levers is indicated below. Do not try and
force the levers beyond their normal extent of travel as this will damage the rotor.
To engage the rollers snap the roller release levers counter clockwise making sure
that the rollers locked out against the tubing. To disengage the rollers, snap the
release levers clockwise to their disengaged position. For high pressure tubing
elements or four roller pumpheads, the 5mm Allen key can be used to aid leverage
when engaging/disengaging the rollers with the release levers.
Make sure that fingers are clear of the front face of the rotor hub
when using the roller release levers.
Pre-load checks
Before loading tubing, ensure that all rollers rotate freely, that the tube ports and
location grooves are clean and that if in use, the controlled waste pipe work is free
of any obstructions.
Closing the pumphead guard and start-up
Ensure that the guard seal is clean, replacing it if necessary.
Ensure that the rollers are engaged and locked out against the tubing
Close the guard and push it against the track until the latch engages.
Connect suitable pipe work to the pumphead using the appropriate connectors for
the tube element.
Continuous tubing clamp location in 620R pumpheads
Select the appropriate tube clamp set for the tubing size to be used.
Locate the two "U"-shaped track clamp halves into the pumphead ports (The "U"-
shape ensures correct loading)
