INSTALLATION & MAINTENANCE
Installation
It is important that these filters are connected with
flat collar sleeves and BSPT threaded couplings.
Connection kits for connecting a Mini Sigma filter
are available.
Read the manual before installing. You will find
installation advice here.
Install a non-return valve on the outgoing side,
to prevent damage due to hydraulic shock, etc.
We recommend mounting the filter horizontally.
Note
:
the filter is supplied as standard with a
100-micron screen. The correct filter screen can be
supplied separately.
Note:
the pipework must have sufficient
load-bearing capacity to bear the total weight of
the filters. If the pipework could twist or bend, for
example, it could damage the filter.
Use the EC or pump start signal to monitor the
flushing frequency and ensure it is at the right level.
Note:
the filter does not have a drain hose from the
coil as standard. Depending on the orientation of the
filter ring, it can be attached later to prevent flushing
water from reaching the filter.
Netafim Netherlands recommends using the
following product for adjusting or extending the
PE hoses: 02058-250051 LDPE 8X6 100M
If there is continuous flow through the flushing valve:
check if the nut at the discharge elbow is sufficiently
tightened, and that the manual control of the coil is in
the horizontal (automatic) position.
