AIR FILTER REPLACEMENT

The air pump that supplies stripping air to the reactor assembly contains a small inlet filter. Over

time, this filter will accumulate dirt and dust removed from the air used by the pump. This filter should be

replaced once a year. Open the rear compartment of the chemistry module to access the pump. On the

inlet of the air pump, you will see a porous plastic filter connected with a short piece of silicon tubing.

Remove the old filter and discard. Replace with a new filter element. One spare filter is supplied with the

unit, and additional filters are listed on the spare parts list.
