MOUNTING THE BACKWASHING FILTER
The built-in rotary flange for the backwashing filter is supplied with bayonet drill holes. The necessary seals
and screws for this backwashing filter have already been mounted.
Do not unscrew the screws!
/
Insert the four flange screw heads through the bayonet drill holes on the built-in rotary flange (see
fig. 6 I).
/
Turn the backwashing filter in a clockwise direction as far as it will go (see fig. 6 II).
/
Tighten the four flange screws.
Select the torque (approx. 10 Nm) so that the gasket closes and the backwashing
filter is not damaged or strained!
The unit may only be installed by skilled personnel. The chapter 4.1 " INTENDED
USE" must always be observed!
The pipes must be able to safely support the backwashing filter. Otherwise mechanical damage or frac-
tures/bursts can occur in the pipes. This can result in major water damage.
Persons close to the backwashing filter are exposed to a health risk due to the large quantities of water re-
leased.
Therefore, if necessary, the pipes must be additionally fixed or supported.
For convenient operation and maintenance it is absolutely necessary to ensure the given spacings. A space
of at least 250 mm should be maintained above and below the backwashing filter. These distances are nec-
essary to be able to properly carry out the backwashing.
The chapters 6.4 „BACKWASH WATER DISCHARGE OPTIONS" and 7.3 „BACKWASHING" must
always be observed!
