Monthly Maintenance
Check inlet /outlet pressures:
When the pressure differential is above 5 m / 7 activate automatic back flush of the Spin Klin
PSI,
filter.
In the event that the pressure differential remains high, check for possible failures.
Check for leakages from the drain manifold:
When there is a leakage of water during the filtration stage, check for possible failure at the
back-flush valve seals.
Back-flush controller performance:
Check that the controller timing parameters are correctly adjusted and activate automatic back-
flush cycle. In the event of possible failure at the back-flush controller, check for possible
failures.
Cleaning of the Command Filter:
Close the command-filter inlet valve; release the pressure trapped at the command-filter and
remove the cover. Thoroughly clean the filtration element, and then reinstall the command filter
element and cover, then open the inlet valve.
Winterization:
In order to prevent the filter battery becoming damaged during water freezing – drain all the water
from the filter battery and the command filter and leave the drain valve open.
NOTE:
Before performing any maintenance work on the battery, make sure all water and air connections
are disconnected and that the pressure has been released.
