Use
3.1
Intended use
The product is used for filtration of drinking and
industrial water to protect the water mains and the
connected fittings, equipment, machinery, tanks,
boilers and production facilities from malfunction
and corrosion damage caused by foreign particles.
The product can also be used for filtration of well,
process, boiler feed, cooling and air conditioning
water. In these cases, advice must be obtained
from a specialist.
The product is unsuitable for oils, greases, solvents,
soaps and other lubricating media. Water-soluble
substances also cannot be separated off.
The intended use presupposes that the filter is
installed, operated and maintained according to the
instructions and regulations of this documentation.
3.2
Foreseeable misuse
Operating the system with parameters other than
those specified in this documentation and in sec-
tion 3.1.
Not adhering to the prescribed maintenance and
service intervals.
Using spare parts and consumables not approved
by BWT.
3.3
Disclaimer
The manufacturer is released from any liability if the
customer intentionally or forcibly removes guards
or safety devices, if the customer wilfully modifies
or circumvents the same, or if the customer does
not follow the instructions in this operating manual
or on the system.
3.4
Other applicable documentation
Observe all documents from suppliers that were
included with delivery. These are considered part
of this documentation and must not be changed
or removed.

Function
The untreated water flows through a stainless
steel filter element in the Multipur. Foreign particles
> 100 µm or > 200 µm are thus retained. Depending
on their size and weight, these particles either fall
directly into the lower part of the filter housing, or
adhere to the filter element.
During backwashing, the seal at the rinsing water
outlet opens. The suction ring segments of the
backwashing element move from the bottom to the
top and back again over the entire filter surface and
thus clean the filter fabric by suction with clean water
at an extremely high flow rate.
Backwashing is carried out automatically at the end
of the set interval.
The pressure difference between the untreated
water inlet and the treated water outlet of the filter
is measured.
The backwashing process is triggered primarily by
differential pressure.
If heavy soiling of the filter element causes the
pressure difference to exceed the preset value
(approx. 0.8 bar) within the preset backwash inter-
val, the differential pressure generator causes the
unit to backwash. The preset backwash interval
starts again.
The filter is equipped with a central instrumentation
and control (CIC) connection (contact closes in the
event of malfunction or power failure).
