Installation
3.3.1 Drainage options for the backwash water

Commissioning
Prior to initial commissioning (or to com-
missioning after maintenance work) fill the
installed device with water and vent:
1.
Open the upstream shut-off valve to fill
the device with water. The device is now
under mains pressure.
2. Attention:
Carry out a backwashing
immediately so that the trapped air can
escape (see chapter 4.1.2)! This pre-
vents damage to the installation by
water hammer pressure surges.
After backwashing, the device is vented
and ready for operation.
