Unseal The Filter: Using the mittens, which are incorporated into
the bag, release the filter-locking latch. For a fluid seal housing,
press the arm firmly inward toward the filter at a point near the
latch to relieve the tension and the latch will automatically
spring to one side releasing the arm. Next pull the arm all the
way outward to the open position. This allows the filter to
release from the knife-edge

For a gasket seal housing, unlock filter by turning both bolt locking
mechanisms counterclockwise with a ratchet. This will release the
filter from the flat edge.

Use filter retrieval rod to latch onto and pull filter into the PVC
bag. One can also reach into unit and pull filter out on a one
wide unit. Slide the filter as far into the bag as possible. A
residual bag stub from previous filter changes may exist. This
should be removed along with the filter.
