Siting
To ensure correct lubrication of the gear box it is important to run the pump
only whilst 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 603S/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 603S/R is suitable for single phase mains electricity supplies only. It is
fitted with a mains selector switch which must be set to the local supply
voltage and frequency. Set the voltage selector switch to either 120V for 100-
120V 50/60Hz supplies or 240V for 220-240V supplies.
Should the pump fail to operate, check that mains electricity is available at the
unit, that the voltage selector switch is in the correct position, that the fuse is
intact and that the pump is not stalled by incorrect fitting of tubing.
There are dangerous voltages (at mains potential) inside the unit. If
access is required, isolate the pump from the mains before removing
the cover.
