not attempt to clean the secondary (inner)
element.
1. Hold a bright light inside element and check
carefully for holes. Discard any element
which shows the slightest hole.

the element.

cleanings or at least every three years.
IMPORTANT
The secondary (inner) element should be
replaced every third time the primary
element is changed.
