Siting
To ensure correct lubrication of the gear box it is important to run the pump
only while its feet are standing on a horizontal surface.
It should be situated where there is free air to circulate around the pump and
where the tubing is allowed to enter the tube clamps without kinking.
The 604S/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.
Electrical connection
The 604S/R operates on single-phase mains electricity supplies only. It will
accept without modification or switching any voltage from 100V to 240V either
50Hz or 60Hz.
Remove the small transparent plate on the rear panel to gain access to the
terminal block. Route the mains supply 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 prominently on the rear panel.
Alternative connectors are supplied to screw into the entry point gland. One
accepts 20mm rigid or flexible conduit, and the other accepts three core 0.75
square millimetre PVC smooth sheathed mains cable with a outside diameter
of 4mm to 7mm (via the screwed adapter supplied) so that a flying lead can
be used. When using a‚ flying lead, ensure that the lead is securely retained
in the strain relief gland so that IP55 ingress protection is maintained.

Securely replace the transparent plate and the gasket over the recess.
Ingress protection standard will be compromised if transparent plate is
not properly replaced.
Should the pump fail to operate, check that mains electricity is available at the
unit, that the fuse is intact and that the pump is not stalled by incorrect fitting
of tubing. If the pump is to be used under manual control and fails to operate,
check that the manual mode has been selected.
There are dangerous voltages (at mains potential) inside the unit. If
access is required, isolate the pump from the mains before removing
the cover.
