Maintenance
To keep the filter in the best working order it is recommended that you follow the
maintenance guidelines below.
• Perform a visual check of the filter housing and seals once a week. If needed, repair
or replace as necessary.
• Clean the filter once a month or as required due to pressure drop, when the
pressure drop across the filter reaches 0.6 bar (8 psi).
• Perform a deep clean at the beginning and end of the irrigation season.
To remove organic material: Soak the screen in a 0.5% hypochlorite solution
(bleach) for 30 minutes. Rinse with clean water and return to filter according to
procedures above.
To remove scale/calcium: Soak the screen in a bath of Puretec SC1000
ScaleSolve for 30 minutes. Rinse with clean water and replace back into the filter.
