General instructions:
This filter is designed and manufactured to meet
the highest standards of quality and
workmanship. This filter is often used as a safety
feature of an installation, as well as a control
filter, pre-filter, and post-filter. The compressed
plastic discs combine the advantages of screen
filtration and deep filtration.
Installation:
The filters can be installed horizontally as well as
vertically. Only use the spanner supplied to
loosen the cover (3”). The water inlet and outlet
are clearly indicated by arrows.
Allow sufficient room to remove the filter cover
and the filter element. When installing more than
one filter, allow enough room between the units
for easy maintenance. A pressure relief valve
must be installed upstream of the filtering
installation if the
pressure is not sufficiently under control.
Operation:
Normal operating conditions are achieved when
the differential pressure across the clean filter
element is less than 0.4 bar.
When the differential pressure exceeds 0.4 bar,
either the filter is partially soiled or it has to
process too large a water flow.
The maximum pressure is up to 10 bar.
Check the differential pressure across the filter
during operation.
Do not open the filter when it is under
pressure. Do not tighten the nut when the
filter is under pressure.
Maintenance:
Regularly check the pressure loss across the
filter. Every year, apply a layer of non-corrosive
grease on the rubber parts.
Periodic cleaning:
It is recommended to clean and inspect the filter
element every 2 weeks or when the differential
pressure reaches 1 bar or more.
Stop the flow to the filter.
Open a flush valve to release pressure and drain
water.
Carefully remove the filter element and open the
disc pack.
Open the disc pack by loosening the clamp nut
holding the pack tightly together.
Thoroughly clean the filter element by holding it
under running water. In order to rinse away the
dirt between the discs, they should be loose. If
calcium has scaled on the discs, dip them into an
acid solution. Wait a few minutes for the solution
to have its effect, and then thoroughly clean the
discs.
Make sure no dirty water enters the system.
Assembly:
Make sure the filter element is intact, clean, and
undamaged. Place the filter element and close
the disc pack. Place the filter cover and tighten it
snugly (3” filter), or with the clamp”s (4” and 6”
filters).
Gradually open the valve before the filter and
check for leaks.
Replacing the discs:
The filter discs are fitted onto a holder. During
filtration, these discs are compressed by clamp
nut. Even when they are in the opened state, the
discs cannot be removed from the holder.
However, they can be easily cleaned under
running water. In case of defective or worn discs,
they must be replaced. Remove the cap screw
from the holder in order to remove the discs.
Place a new set of discs onto the holder,
ensuring the number of discs or the pack length
is correct, and fit the cap screw. Install the filter
pack as described for the assembly.
Notes:
Each filter comes with this manual which
includes the installation, operating, and
maintenance instructions.
In view of on-going improvements, we reserve
the right to change specifications at any time
without prior notice.
