11.1 Pre-filter with back wash
The pre-filter should be checked every 3 months, and cleaned if necessary. The auto-clean interval can
then be extended depending on the build-up of contaminants.
The integrated non-return valve (PR100-M) must be checked twice a year and cleaned of any deposits.
11.2 Filtration and backwash pump
It is recommended that a function test of the pumps is carried out every six months. Each pump is started
in the test menu. (Can be also used to check the flow.)
In the case where one pump should fail, the complete double pump unit should be replaced.
It is suggested that the filtration and backwash pump set be replaced after 20,000 hrs running time.
11.3 Float Switch / Level Sensor
It is recommended that a function test of the float switch is carried out every six months. The float switch
is tested by manually positioning it into the two switch positions (Empty=lower position /Full=upper
position) while the display is checked.
