Recommended operating procedures
DO keep delivery and suction lines as short as possible using a minimum number of swept bends.
DO use suction and deliver y pipelines with a bor e equal to or larger than the bore of the tube fitted in the pumphead.
When pumping viscous fluids, the losses caused by increased friction can be overcome by using pipe runs with a cross
sectional area several times greater than the pumping element.
DO fit an ex tra length of pump tube in the s ystem to enable tube tr ansfer. This will extend tube lif e and m inimise the
downtime of the pumping circuit.
DO
keep the track and rollers clean.
The self-priming nature of peristaltic pumps means valves are not required. Any valves fitted must cause no restriction
to flow in the pumping circuit.
Tube selection T he chemical compatibility list published in the W atson-Marlow catalogue is only a guide. If in doubt
about the compatibility of a tube material with the duty fluid, request a tube sample card for immersion trials.
Installation
The 101F/R and 101U/R are suitable for single phase mains electricity supplies only.
•
To ensure correct lubrication of the gearbox the pum p should be run only while its feet are standing on a horizontal
surface. The pump should be positioned to allow a free flow of air around it.
Set the voltage selector to either 120V for 100-120V 50/60Hz supplies or 240V for 220-240V 50/60Hz supplies.
A mains cable fitted with a moulded plug is supplied with the pump. The wires are colour coded in accordance with the
following code:
•
220-240V: Live- Brown; Neutral - Blue; Earth - Green/Yellow.
•
100-120V: Live - Black; Neutral - White; Earth - Green.
Troubleshooting
Should the pump fail to operate, make the following checks to determine whether or not servicing is required.
•
Check that the power switch is on.
•
Check the mains supply is available at the pump.
•
Check the voltage selector switch is in the correct position.
•
Check the fuse in the mains socket.
•
Check that the pump is not stalled by incorrect fitting of tubing.
101F/R operation
•
Turn power switch to on (I) position to start pump.
•
Turn power switch to off (0) position to stop pump.
101U/R Manual operation
•
Set the front panel Auto/Man switch to Man.
•
Turn power switch to on (I) position to start pump.
•
Turn power switch to off (0) position to stop pump.
•
Change pumping direction using the CW/CCW switch on the front panel, and s et the pum p speed using the digital
potentiometer which is calibrated in percentage of maximum speed.
•
To prime the pump at maximum speed press the Max key.
It is not nec essary to dis connect the pr ocess s ignal f rom the r ear panel 15-pin D connector or adjust the calibration
potentiometers if returning to manual control after the pump has been in automatic operation.
