Close the motorized backwater flap (4) by pressing the flap
close button on the control unit. Manually lock the second flap
by closing and locking the emergency closure lever (3). Un-
screw the red ½ inch test plug (1) on the cover and connect the
supplied see-thru test funnel (2). Add clear water into the funnel
until the water level inside the funnel reaches the 10cm mark
(this may require significant filling of water since the Staufix FKA
body must first be completely filled with water before the filter
level is reached). Over a 10 minute period, observe the water
level inside the see-thru funnel. If the water level decreases,
refill to the 10cm mark and record how much water is required
to keep the water level at 10cm. If no more than 500ml of water
was required to keep the water level at the 10cm mark during
the 10 minute test then the valve is considered tight.
After the test re-open the manual closure lever (3). Remove the
filter (2) and replace the red test plug (1). Make sure the test
plug is firmly screwed to assure that the entire backwater valve
cover is watertight. Re-open the motorized backwater flap by
pressing the flap close button which will re-open the flap.

Caution:
- When removing both covers make sure both closure levers are in the open

- When replacing both covers, both closure levers must be in the vertical
position.
- When replacing the cover, the violet flap lever must always be in the Closed
setting
