Three year warranty

Watson-Marlow Limited warrants, subject to the conditions below, through either Watson-Marlow Limited, its subsidiaries, or its

authorised distributors, to repair or replace free of charge, including labour, any part of this product which fails within three years of

delivery of the product to the end user. Such failure must have occurred because of defect in material or workmanship and not as a

result of operation of the product other than in accordance with the instructions given in this manual.

Conditions of and specific exceptions to the above warranty are:

•

Consumable items such as tubing and rollers are excluded.

•

Products must be returned by pre-arrangement carriage paid to Watson-Marlow Limited, its subsidiaries, or its authorised

distributor.

•

All repairs or modifications must have been made by Watson-Marlow Limited, its subsidiaries, or its authorised distributors or

with the express permission of Watson-Marlow Limited, its subsidiaries, or its authorised distributors.

•

Products which have been abused, misused, or subjected to malicious or accidental damage or electrical surge are excluded.

Warranties purporting to be on behalf of Watson-Marlow Limited made by any person, 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 Watson-

Marlow Limited unless expressly approved in writing by a Director or Manager of Watson-Marlow Limited.

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.

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.

There are dangerous voltages (at mains potential) inside the pump. If access is required, isolate the

pump from the mains before removing the cover.

Recommended operating procedures

DO keep delivery and suction lines as short as possible using a minimum number of swept bends.

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 run at a slow speed when pumping viscous fluids. When using the 501RL pumphead, a 4.8 or 6.4mm bore tube with a 1.6mm

wall will give best results. Tube smaller than this will generate a high -friction pressure loss, so reducing the flow. Tube with a larger

bore will not have sufficient strength to restitute. Flooded suction will enhance pumping performance in all cases, particularly for

materials of a viscous nature. Silicone and Marprene tubing is available with a 2.4mm wall thickness for speeds up to 200rpm. (The

rotor will require re-setting to a roller/track gap of 3.8mm.)
