7. Spin Klin – System Maintenance
Monthly Maintenance
Check inlet / outlet pressures:
When the pressure differential is above 5 m / 7 PSI, activate automatic back flush of the Spin Klin 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.
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.
To avoid damage or breakage, the filter, solenoid and command tubes, must be drained prior to frost
periods. A step by step instructions:
1. Initiate a manual flush to make sure that the disc element will be clean for the shutoff period.
2. Close the isolation valves (inlet and outlet if exist).
3. Initiate an additional manual flush to release the pressure inside the filter.
4. If available, open any drainage filter body valve
5. Disconnect the tubes that supply water to the solenoid and to the controller sensors.
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.
