Follow the steps below to clean the Tempest filter:
STEP 1: Switch pump off.
STEP 2: Close all slide valves on inlet and outlet.
STEP 3: Open the tap(s) on the waste valve assembly. Air enters the filter causing the filter media to move and clean as the water drains to waste.
STEP 4: Once the water has emptied from the filter(s) and the media sinks to the bottom, close the tap(s) on the waste valve assembly.
STEP 5: Open all slide valves on inlet and outlet.
STEP 6: Turn pump back on. Water will re-fill the tube and media will rise to the top.
