Watson-Marlow 701S/R - Manual (Page 5)

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).
Supplies
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.
Back panel
Power cable
5 to 8mm outside diameter
M20 for direct conduit connection
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.
