How to proceed:
1. Close the slide valve for the dirt outlet DN 75.
2. Check that the entire filter system (pipes and hoses) is complete.
3. Fill the filter modules with water.
–
Pump fed system: Switch on the filter pump.
– Gravity fed system: Open the slide valves (supply and return) of the filter series to allow the
water to flow.
4. Check all pipes, hoses and their connections for leaks.
– Expansion seals may leak initially until they have fully expanded on contact with water.
5. Switch on all other electrical devices of the filter system as soon as all filter containers are
filled with water.
–
Leave the UVC clarifier switched off for at least 24 hours if you are using filter starters (e.g.
OASE BioKick). Otherwise it will impair colonisation of the filter materials with micro-organ-
isms.
Maintenance and cleaning
Dead biomass drops to the bottom and has to be removed. To do this, open the DN 75 dirt outlet
for approx. 10 seconds.

The entire filter system only needs to be taken out of operation for cleaning and maintenance
if it is extremely soiled.

Do not use chemical cleaning agents, as these will kill the filter bacteria.
Cleaning the tank

fier).

vent further water flow.
3. Open the slide valve of the dirt outlet DN 75 on the container and dispose of the dirt water in a
permissible manner.
