PUMP MODULE
There are two field replaceable parts on the aspirated case: the water barrier and case top door. As needed, choose,
read, and follow the appropriate instruction set(s).
PUMP MODULE
Pump Inlet Filter Cap and/or Water Barrier Replacement (if needed).
1 To remove the pump inlet filter cap, turn counter clockwise; set aside.
2 Remove the water barrier from inside the inlet.
3 To properly place the new water barrier, its bottom will come into contact with the pump inlet surface on
which the barrier sits. The barrier's bottom side has the smaller diameter opening in the black ring.
4 Re-place the pump inlet filter cap (or new cap); turn clockwise to tighten.
Pump Door Removal and Replacement (if needed).
1 Loosen the single captive screw on the pump module door.
2 Slide the door down and lift.
3 The upper portion of the door has pegs on either side. The pegs fit into grooves where the door meets
the module; they flex slightly for easy door removal. Angle the door so that one peg moves to the bottom
of its groove and the other moves the top of its groove. Lift to unhinge the pegs and remove the door.
4 To properly place the new door, secure one of the pegs into its groove on the pump module.
5 Angle the door and press the other peg into its groove.
6 Close the door and slide up into place.
7 Tighten the single captive screw on the pump door.
