Cleaning With Cleaning Solution By Filling The Uv System - ProMinent 80 W Assembly And Operating Instructions Manual

8.2 Cleaning with Cleaning Solution by Filling the UV System

WARNING!
Live parts!
Possible consequence: Fatal or very serious inju‐
ries
– Measure: Disconnect the device from the
power supply before opening it.
– Disconnect damaged and defective devices or
devices that have been tampered with from the
power supply.
CAUTION!
General precautionary measures
Ensure that the reactor is at atmospheric pressure
before carrying out any maintenance work.
NOTICE!
Maximum permissible service life
Replace the UV lamps at the latest when their
maximum permissible service life expires. Other‐
wise, the operating safety of the UV system can no
longer be guaranteed.
The maximum permissible service life is 14,000
operating hours, unless otherwise stated in the
accompanying data sheet.
Maintenance of the UV system is limited to cleaning the UV
sensor/UV sensor window and replacing the UV lamp at the end of
its maximum permissible service life.
An operating log must be maintained in order to document any
maintenance work carried out; a form is included in the Appendix.
NOTICE!
Handling the cleaning solution
– It is also recommended with reactors, which
are regularly cleaned by filling them with a
cleaning solution, that the water drain con‐
nector and the vent screw are replaced by
appropriate valves.
– With larger reactors, it is recommended that
they are filled through the water drain opening
using an appropriate acid-resistant pump.
– If the reactor is filled with a pump, it is also
useful to circulate the cleaning solution through
the vent opening.
– This shortens the cleaning time and ach‐
ieves a better result.
– If the cleaning solution is collected and stored
in a suitable storage tank, it can be reused sev‐
eral times.
