4-3-3 Check Valve: The discharge flange has an integrated check valve. The valve is held in place by a support backing plate
that is also connected to the discharge hose. To access the check valve, first remove the discharge flange from the main
cover by removing 4 screws. Then, remove the hose followed by the two screws. The hose nipple can then be separated
from the flange by pulling it outward. The check valve snaps onto the hose nipple. When reinstalling, the hinge of the
check valve must be aligned with the "notch" in the hose nipple or backing plate. After installation of the hose nipple,
confirm the check valve opens completely.
4-3-4 Access cover: The access cover is secured to the main cover with five fasteners. If required, use the 3/16 Allen wrench
supplied to loosen the fasteners. Once the screws have been removed, the access cover can be lifted upward. Some
manipulation might be necessary if the Macerator is located directly under the toilet's reservoir tank.
a) Once the access cover is removed, the power cartridge can be slid towards the opening by grasping the handle of
the basket and pulling to the right towards the opening. In some instances, debris might be caught between the tank
and the basket so some manipulation might be required.
b) With the power cartridge fully slid over, the cutters should be in view at the center of the basket. Any obstruction or
object can be removed at this point. The cutters are very sharp and extreme caution should be used.
c) To replace the cutters the 3/16 Allen wrench (supplied) should be inserted into one of the holes located on the
basket floor. This will create a wedge preventing the blade assembly from turning. The locking fastener can be
unscrewed with the use of a 7/16" socket (1/4" drive). Once loose, the screw and cap can be removed by pulling
upward which exposes the two razor blades. Liberty Pumps recommends stainless steel blades, although any
common utility knife style razor blade with two holes can be used as a replacement. When replacing the razor blades
simply insert the blade onto the two pins. The cap and screw should then be replaced.
d) The base of the cutting cartridge can be replaced as well. After removing the razor blades a thin slotted screwdriver
can be inserted into the center hole and once engaged the base can be rotated counterclockwise until it is free.
