Declarations

When the 604S/R pump is used as a stand alone pump it complies with:

Machinery Directive 89/392/EEC and EN60204-1

Low Voltage directive 73/23/EEC and EN61010-1

EMC Directive 89/336/EEC and EN50081-1/50082-1

Responsible person: A S Balding, Managing Director, Watson-Marlow
Limited, Falmouth, Cornwall TR11 4RU, England.

When the 604S/R is to be installed into a machine or is to be assembled with
other machines for installations, it must not be put into service until the
relevant machinery has been declared in conformity with the provisions of the
Machinery Directive 91/368/EEC EN60204-1.

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 unit. If access is
required, isolate the pump from the mains before removing the cover.

Information for returning pumps

Any 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 (a suitable blank form is 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.

Two 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 two 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.

Recommended operating procedures

DO keep delivery and suction lines as short as possible.

DO use the minimum number of bends in rigid pipe runs. If there must be a

bend, use a swept bend and not a tight elbow.

DO run at a slow speed when pumping viscous fluids. 9.6 or 12.7mm bore
tube with a 3.2mm wall will give best results. Tube smaller than this will
generate a high friction pressure loss which reduces the flow. Tube with a
larger bore will not have sufficient strength to restitute. Flooded delivery will
enhance pumping performance. Some tube materials are available with a
4mm wall for speeds up to 100rpm.(The rotor will require re-setting to a roller
track gap of 6.6mm.)

use suction and delivery pipelines with a bore equal to or larger than the

DO

bore of the tube fitted in the pumphead. When pumping

viscous

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 use the largest possible bore tube running at slow speed for the longest
tube life.

DO fit an extra length of pump tube in the system so that you can move the
tube through the pumphead occasionally, without needing to break the
pumping circuit. This is particularly useful for extending tube life in long
running sterile applications.

DO keep the track and rollers clean, and ensure that the rollers are free.

fluids, the

DO NOT fit valves in the suction or delivery line without considering that
peristaltic pumps are self priming and will hold their prime up to several
metres, so there may be no need for non-return or foot valves, nor for the
loading valves required on many other kinds of pumps.

Any valves fitted must cause no restriction. If electrically actuated valves are
fitted, they should be interlocked so that the pump will only run when the
valves are open. Fit an automatic by-pass if manual valves are installed.

When using Marprene or Bioprene tubing, after the first 30 minutes of
running, re-tension the tube in the pumphead by releasing the tube clamp on
the delivery side a little and pulling the tube tight. This is to counteract the
normal stretching that occurs with Marprene and Bioprene, which can go
unnoticed and result in poor tube life.

Tube selection The chemical compatibility list published in the Watson­Marlow 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.
Remember the sample will be fully immersed, but the fluid when in use will
only be in contact with the inside of the tube. If the material swells but does
not lose its strength it could be worth considering.

Viscous dispensing To overcome the common problems of reduced
accuracy and dripping delivery pipes, the suction and delivery lines should be
kept as short as possible. Use larger bore transmission tubing than that in the
pumphead to keep the friction losses to a minimum. Improved accuracy will
be noticed if rigid or semi-rigid pipe is used on the delivery side. The rigid tube
is effective in reducing over-run because it does not expand during pumping.
