Declaration of
incorporation

When the 701S/R pump 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 89/392/EEC and EN60204-1.

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 glands 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.

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.

Ensure the drive is inoperative before opening the track cover

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

In the current situation of heightened concern over the handling of hazardous
materials, 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.

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 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 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.

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 may 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.

Part 1: 701S/R Drive

Siting

The 701S/R can be operated at ambient temperatures from 5C to 40C.
Storage temperatures from -40C to 70C are permissible, but allow time for
acclimatisation before use. The pump should be positioned to allow a free
flow of air around it.

Should the pump fail to operate, check that mains electricity is available at the
unit, that the fuses are intact and that the pump is not stalled by incorrect
fitting of tubing.

A drain hole (tapped 1/4" BSP) is provided at the left hand side of the
pumphead base which is plugged during assembly. If required, the plug can
be removed and a drain hose connected.

Installation

The 701S/R is suitable for single phase mains electricity only. Ensure that the
supply voltage and frequency correspond with those marked with a white dot
on the rear panel, (220V 50/60Hz, 120V 50/60Hz or 100V 50/60Hz).

Remove the small plate on the rear panel to gain access to the terminal block.
Route the mains cable through the entry point to the right of the recess and
couple the cable to the terminal block in accordance with the instructions
printed on the rear panel. Two alternative connectors are supplied to screw
into the entry point gland. One accepts 20mm rigid or flexible conduit, and the
other accepts a three core 0.75 square mm PVC sheathed mains cable (via
the screwed adaptor provided) so that a flying lead can be used. Securely
replace the transparent plate and gasket over the recess.

Power cable
5 to 8mm outside diameter

M20 for direct conduit connection

Supplies

Back panel

Ingress protection standard will be compromised if transparent plate is
not properly replaced.

There are dangerous voltages (at mains potential) inside the motor. If
access is required, isolate the pump from the mains before removing
the cover.
