Routine Maintenance
Responsibility
To preserve the life and efficient operation of the equipment it is important that the
equipment is properly maintained. Regular maintenance of the equipment is the
responsibility of the end user and must be performed by qualified personnel who
understand the operation of the equipment.
General
The equipment should be disconnected from the electrical supply when not in use.
The process vessels, optional reactor vessel, heating/cooling coil and pipework
should be drained after use. Water pumped through the equipment will remove
chemical deposits from the pumps, flowmeter, supply lines etc.
In areas of hard water, the amount of scale in the process vessels and pipework can
be reduced by fitting a de-ioniser in-line with the water supply to the equipment.
After use, release the heads of the peristaltic pumps by pivoting the clamp on the
pump head upwards and backwards to expose the rotor. This takes the pressure off
the flexible tubing and will prolong the life of the tubing.
The life of the flexible tubing used in the peristaltic pump heads can be extended by
moving the tubing through the pump head to an unused section at regular intervals.
When replacement of the flexible tubing is necessary it is important to ensure that the
replacement tubing is compatible as follows:
