Maintenance
Maintenance includes periodic backwashing to remove floating dirt particles,
silt, sand, etc. from the filter cartridge.
It is recommended to backwash at least once a month. The arrow in the
month bar signals the next backwash period and must be adjusted to the next
date after backwashing.
Backwash
A backwash must be carried out if the water pressure in the pipe network
decreases due to increasing contamination of the filter element. Place a buck-
et under the filter (only for installation without duct connection). Then turn the
flushing handle in the direction of the arrow up to the stop (Fig. 3 + 4). The
flushing handle should be held in this position for approx. 5-10 seconds.
