8. Operators' obligations

According to German legislation
You have purchased a durable and service-friendly
product. However, all technical plants require regu-
lar servicing to keep them in perfect working order.
The pre-requisite for functioning and the warranty is
the replacement of the filter element and the visual
inspection for leakproofness by the operator.
Verification of initial pressure every 2 months in the
case of zero flow and high levels of water removal.
A further pre-requisite for functioning and the war-
ranty is replacing wearing parts at the prescribed
maintenance intervals (see '12. Maintenance ins-
truction').
In accordance with DIN EN 806-5, wearing parts
must be replaced by experts (installer or factory ser-
vice centre).
We recommend entering into a maintenance con-
tract with your installer or factory service centre.
Note: Filters should not be operated by children.
Squeezing of the hand/fingers is possible.

9. Warranty

In the event of breakdown during the warranty pe-
riod, where a maintenance contract exists please
contact our factory service centre, specifying the
type of device (see technical data or type plate
on the device). Work under warranty may only be
executed by our factory service centre. Works per-
formed under warranty by a specialist firm require
explicit commissioning by our customer service de-
partment.
If no maintenance contract exists, please contact
your in-house installer.
