8. Reminder service
With the BWT reminder service, BWT's mainte-
nance information service will remind you on a
regular basis when it is time to change the filter
element and also provide important hints and tips
on hygiene. In combination with the reminder ser-
vice and the regular change of the filter element
or hygiene kit, an extended 10-year E1 guarantee
is available, depending on the national subsidiary
(see item 10).
9. 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 vi-
sual 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
warranty is replacing wearing parts at the prescri-
bed maintenance intervals (see '12. Maintenance
instruction').
In accordance with DIN EN 806-5, wearing parts
must be replaced by experts (installer or factory
service 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.
