Maintenance
Always disconnect pump (macerator) from power source
before handling or making any adjustments. Fatal electrical
shock could occur.
The macerator is designed such that every component can easily
be serviced or replaced as necessary. Replacement parts can be
ordered at www.LibertyPumps.com/Service/Replacement-Parts/.
The macerator is designed with a removable access cover, making
the unit serviceable without removing the macerating unit from
the toilet or disconnecting any plumbing.
Cleaning
All standard cleaners can be used just as with a standard
conventional toilet. The exterior of the macerating unit may be
cleaned with a damp cloth and normal household cleaners. Never
spray or dump water or chemicals directly on the unit.
Decorative Covers
The right cover can be removed by pulling it horizontally away
from the macerator and then lifting vertically. The left cover is
secured and positioned by two mating posts on the main cover.
Discharge and Vent Flanges
Both the discharge and vent
flanges are fastened to the main
cover and can be removed by
unscrewing the four fasteners
and pulling the flange away from
the main cover.
Toilet Sealing Ring
The seal between the toilet and
the macerator consists of a rubber
ring connected to the macerator
into which the toilet slides. The
rubber ring stretches and forms a
seal around the discharge hub of
the toilet. This rubber ring is
replaceable by unclipping the
plastic retainer and then pulling
the ring outward. Installation is
reversed, first slide the rubber ring
onto the macerator, followed by
the retaining ring.
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.
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 reservoir tank.
Once the access cover is removed, the power cartridge can be slid
toward the opening by grasping the handle of the basket and
pulling to the right toward the opening. In some instances, debris
might be caught between the tank and the basket so some
manipulation might be required.
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.
Interconnect Hose
A hose connects the discharge of the motor cartridge (pump) to
the discharge flange. To remove this hose, follow the procedure
Discharge and Vent Flanges and Accessibility to Motorized
Cartridge. Both ends of the hose are secured with clamps.
RISK OF ELECTRIC SHOCK
The hinge of the
check valve must
be aligned with
the notch in the
hose nipple.
Once the access cover is removed,
pull the power cartridge towards
opening
