Installation
Preliminary checks
DANGER! - EXPLOSION HAZARD
Failure to inspect the pumphead unit for damage or check the ATEX
labelling data may cause a fire or explosion.
Check the label on the pump to ensure that the pump type and the ATEX labelling conform to the
planning of the plant or machine.
Check that all components are present. Inspect components for damage in transit. If anything is missing
or damaged, contact your Watson-Marlow representative immediately.
Mechanical installation
Fundamental work with regard to lifting, transportation, installation,
starting-up, maintenance and repair should be performed by qualified
personnel only. The unit must be isolated from mains power while
work is being carried out. The motor must be secured against
accidental start-up.
Some pumps weigh more than 18kg (the exact weight depends on the
model and pumphead - see on the pump). Lifting should be performed
according to standard Health and Safety guidelines.
Explosion hazard. Failure to comply may cause severe or even fatal
injuries.
All work, e.g. transportation, storage, installation, connection,
commissioning, servicing and maintenance must be performed in a
non-explosive atmosphere.
Site the pump on a flat, horizontal, vibration-proof surface allowing a free flow of air around it. Ensure
there is 0.5m of straight tubing before the pumphead inlet and after the pumphead outlets.
If the pump is not supplied attached to a baseplate then the unit must be bolted down to a suitable
substrate via the bolting holes identified in the motor and gearbox manuals.
Refer to the manufacturers instructions for the motor and gearbox for further installation instructions.
