including representatives of Watson-Marlow Limited, its subsidiaries, or its distributors,
which do not accord with the terms of this warranty shall not be binding upon Watson­Marlow Limited unless expressly approved in writing by a Director or Manager of Watson­Marlow Limited.

4 Information for returning pumps

Equipment which has been contaminated with, or exposed to, body fluids, toxic chemicals
or any other substance hazardous to health must be decontaminated before it is returned to
Watson-Marlow or its distributor. A certificate included at the rear of these operating
instructions, or signed statement, must be attached to the outside of the shipping carton.
This certificate is required even if the pump is unused. If the pump has been used, the
fluids that have been in contact with the pump and the cleaning procedure must be
specified along with a statement that the equipment has been decontaminated.

5 Safety

In the interests of safety, this pump and the tubing selected should only be used by
competent, suitably trained personnel after they have read and understood this manual,
and considered any hazard involved. Any person who is involved in the installation or
maintenance of this equipment should be fully competent to carry out the work. In the UK
this person should also be familiar with the Health and Safety at Work Act 1974.

This symbol, used on the pump and in this manual, means: Caution, risk
of electric shock.

This symbol, used on the pump and in this manual, means: Caution, refer
to accompanying documents.

This symbol, used on the pump and in this manual, means: Do not allow
fingers to contact moving parts.

Fundamental work with regard to lifting, transportation,
installation, starting-up, maintenance and repair should be
performed by qualified pers onnel only. Make absolutely sure
that no voltage is applied at all while work is being carried
out on the geared motor. The motor must be secured against
accidental start up.

6 Recommended operating procedures

On variable speed models please note that the mechanical speed variator must not be

adjusted when the motor is not running.

Do site the fluid reservoir above the pump wherever possible.

Do keep delivery and suction lines as short and direct as possible.

Do use gradual sweeping bends in installation pipe work with minimum radius equal to five

times the tubing diameter. Avoid tight pipeline bends, pipe reducers and excessive lengths
of smaller bore tubing than that in the pumphead, particularly in pipelines on the suction
side.

Do ensure that there is always a minimum of one metre of smooth bore flexible tubing
connected to the discharge port of the pumphead. This will help minimise any impulse
losses and pulsation in the pipeline. This is especially important with viscous fluids and rigid
pipework.

Do use suction and delivery pipelines with a bore 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 over-length pump tube in the system to allow its position to be varied relative to
the rotor. This will extend tube life and minimise the downtime of the pumping circuit.

Do ensure that connecting pipe work and fittings are suitably rated to handle the predicted
pipeline pressure.

If rigid pipe work comes in close proximity to the pumphead, a drop out section of pipe
work will simplify tube replacement.

Do keep the pumphead rollers and track clean.

If unsure of an installation please contact your local Watson-Marlow Technical Support

Office for further assistance.

The self-priming nature of peristaltic pumps me ans valves are not required. Any valves
fitted must cause no restriction to flow in the pumping circuit.

Tube selection. The chemical compatibility list published in the Watson-Marlow catalogue is
only a guide. If in doubt about the compatibility of a tube material and the duty fluid,
request a tube sample card for immersion trials.

7 Installation

Pump

Site the pump on a flat , horizontal, vibrat i on-proof surface allowing a free flow of air around
it. Ensure there is 1m of relatively straight flexible tubing before the pumphead inlet and
after the pumphead outlets. Two 15mm-diameter holes are provided for bolting the
baseplate to the mounting surface, if required.

AC Motor

 Ensure that mains voltage/frequency are in accordance with motor nameplate

information.

 Secure protective conductor connections.
 If a three-phase motor is running in the wrong direction, interchange any two phases.
 Close unused cable entrance holes and the terminal box itself in a dust and watertight

manner.

 A current overload relay should be fitted to a contact breaker. Connect the motor in

accordance with the wiring diagram that is in the motor terminal box.

 When a thermal protection switch is fitted in the motor, the leads will be found in the

motor terminal box. They should be connected to stop the pump if the switch operates.
The switch will open circuit at an over temperature condition. See below for the
connection of the drive motor showing possible ancillary switches and protections.

1. Emergency
stop

2. Start

3. Stop

The ancillary switches are rated to 220/240V 1ph 50Hz. The Start contact should
have a sprung return which will disengage following energisation of the coils C1
and C1/1.

Ensure that an emergency stop switch is fitted within reach of the pump.

The 701R pumphead range has electrostatic earth straps which are
connected to the baseplate. Please ensure that the baseplate is
electrostatically earthed to ground before operation.
