Safety Guidelines
Safety Precautions
Accidental contact with electrically live parts, items, fluid, or
water can cause serious injury or death.
Always disconnect pump (macerator) from power source
before handling or making any adjustments. Fatal electrical
shock could occur.
The pump shall be plugged into a properly fused electrical
outlet with a ground fault circuit interrupter (GFCI) that
conforms to current National Electric Code (NEC) and all
applicable local codes. All wiring must be performed by
qualified personnel.
All electrical and safety practices shall be in accordance with
the National Electrical Code®, the Occupational Safety and
Health Administration, or applicable local codes and
ordinances.
Pump shall be properly grounded using its supplied
grounding conductor. Do not bypass grounding wires or
remove ground prong from attachment plugs. Failure to
properly ground the pump system can cause all metal
portions of the pump and its surroundings to become
energized.
Do not handle or unplug pump with wet hands, when
standing on a wet/damp surface, or in water. Fatal electrical
shock could occur.
Do not lift or carry the pump by its power cord. This will
damage the power cord, and could expose the electrically live
wires inside the power cord.
The electrical power supply shall be located within the length
limitations of the pump power cord, and for below grade
installations it shall be at least 4 ft (1.22 m) above floor level.
Do not submerge macerator or allow macerator to be
exposed to water. Macerating toilet system is acceptable for
indoor dry location use only. Serious injury or death could
result.
Do not use an extension cord to power the product.
Extension cords can overload boththe product and extension
cord supply wires. Overloaded wires will get very hot and can
catch on fire.
Explosion hazard during installation. PVC cleaners, primers,
and cements can release explosive vapors. These
heavier-than-air vapors can accumulate in the tank. The heat
of soldering or sweating copper or other metal pipe can
ignite these vapors causing a violent explosion. If the unit is
to be connected to copper discharge or vent piping, all
solvent-welded PVC joints must be allowed to cure a
minimum of 24 hours. The access cover must be removed to
allow the tank to be thoroughly ventilated prior to sweating
copper pipe near the unit.
These pumps are not to be installed in locations classified as
hazardous in accordance with the National Electric Code®,
ANSI/NFPA 70.

of the pump, or damage the pump and its components.
All pump/pump system installations shall be in compliance
with all applicable Federal, State, and Local codes and
ordinances.
Do not remove any tags or labels from the pump or its cord.
Keep clear of suction and discharge openings. To prevent
injury, never insert fingers into pump while it is connected to
a power source.
The macerator has a large opening to accept the discharge
hub of a rear discharge toilet. Do not place hand or other
objects into this opening even if unit is unplugged. The
macerator has razor sharp cutters within this opening.
Decorative covers must be installed for operation as a safety
device is integrated into the covers to prevent unintended
operation. The unit may start when energized the first time.
This product contains chemicals known to the State of
California to cause cancer and birth defects or other
reproductive harm. www.p65warnings.ca.gov.
This pump has been evaluated for use with water only.
Wear Protective Personal Equipment to protect hands as
exposed cutter blades have sharp edges.
Do not use pumps with fluid over 104°F (40°C). Operating the
pump in fluid above this temperature can overheat the pump,
resulting in pump failure.
Do not use an air admittance valve or a mechanical
spring-loaded venting device, as these devices are one-way
valves. The air pressure in and outside the macerating pump
unit must be equal and a “cheater” vent will obstruct the
airflow in one direction and prevent proper toilet function.
The Ascent II macerating unit includes electronic controls and
must be protected from direct water exposure during
installation and use.
Sanitary fixtures connected to the macerating system must be
located on the same floor level.

General Information
The macerator is designed to accept wastewater from a rear
discharge toilet but can also simultaneously receive wastewater
from several sanitary fixtures such as a sink, shower, bathtub, or
urinal (a single bathroom group). However, only one water closet
(toilet) per unit may be connected.
Usage
The macerating system is designed for the disposal of human
waste, toilet paper, and water. It is not intended for kitchen waste,
nor is it intended to be used for the disposal of wastewater from
such pumped appliances as dishwashers and clothes washers. This
product is not designed for emptying large pools or spas.
The macerating system starts automatically once the toilet is
flushed or liquid from other fixtures enters the unit. It
automatically shuts off once the contents have been pumped
away. Run times will vary depending on inflow and source.
Features
•Improved cutter design with RazorCut™ system. The cutter
blades are designed and rigorously tested to last
indefinitely without need for service or replacement in
ordinary applications.
•The CleanConnect™ Seal allows the macerator to sit closer
to the toilet.
•QuickFlip™ discharge and vent connectors allow for
horizontal or vertical pipe connections.
Bath Layout
Sanitary fixtures connected to the macerating system must be
located on the same floor level.
The toilet works as a conventional flushing toilet and needs no
special maintenance with normal use.
Any regular bathtub (up to 100 gallons) or shower can be used.
When installing these fixtures, build a 6 inch high platform for the
fixture to be placed. This provides enough space for a p-trap and
slope toward the macerator auxiliary inlets. When installing a
shower, manufacturers sometimes offer a prefabricated raised
shower base. Note: The actual distance between the p-trap of the
additional fixture and macerator determines the necessary
clearance to install the p-trap and elevation required to ensure a
minimum pitch of 1/4” per foot drop.
Normal Operating Cycle
The macerator controls are capable of distinguishing between
different modes of operation and optimizes the run time
accordingly.
Advanced run detection will energize the cutters once the unit
detects a flush. In doing so, the cutters are spinning at maximum
speed (rpm) prior to fluid and debris reaching the cutting system.
The unit may pulse during a shower or draining a bathtub because
the macerator can pump at a higher rate than the incoming flow.
Use and Care
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.

Macerating Unit
User Interface
The macerator has a user
interface (touchpad with LEDs)
located on the top left side of
the unit.
This interface has three LEDs:
ALARM: unit is unable to
evacuate the holding tank or
cannot keep up with the
incoming flow. Audible alarm
also activates.
LOW BATTERY: 9V battery needs
to be replaced.
POWER: unit has power.
The interface also has two
pushbuttons:
PUSH to Silence: silences the
audible alarm.
PUSH to Run: overrides the
internal switch to manually run
the macerator and pump.
Alarm
The macerator has an integral alarm that will sound if the unit
cannot remove liquid or keep up with incoming water. If the alarm
sounds, a number of conditions could exist. Refer to the
Troubleshooting section to determine the cause and solution.
A silence button located on the user interface touchpad stops the
audible alarm. The red alarm LED will continue to illuminate.
Discontinue using the product until the problem has been
identified and resolved.
IMPORTANT: In the event of a power outage, a 9V battery will
power the alarm, and if necessary, the macerator will accept two
flushes prior to alarm activation. After that, the unit should not be
used again until the power is restored. The alarm automatically
resets once a normal cycle is performed.
Low Battery
If the yellow LED is illuminated, the 9V battery needs to be
replaced. The expected life of the supplied battery is 5 to 7 years.
Power
The LED will be green when power is applied, but LED must be
steady to operate. Both decorative covers must be properly in
place to engage safety switch.
Decorative Covers
The decorative covers are shipped
from the factory assembled on the
unit. However, during the installation
both covers must be removed from
the macerator.
Battery Access
The battery receptacle is accessible
under the left decorative cover. Do not
install battery until the unit has been
installed, connected, and ready for
operation.
Auxiliary Inlets
The macerator unit is equipped with
two inlet ports, one on each side.
These ports are designed for standard
PVC pipe. Included with the system are
two 2” flexible PVC couplers and
1-1/2” reducing bushings. These inlets,
which incorporate an internal check
valve, are used to connect the
drainpipe of other sanitary fixtures to
the macerating pump unit.
Typically, the 2” drain is used with
shower stalls only. A tub, shower/tub
combo, or sink would use a 1-1/2”
drain line. From the factory, the
auxiliary inlets are plugged; if the port
is to be used, the plug must be removed by rotating until the rib is
vertical and then pulling outward. If the unit has been stored for
some time, pliers may be needed to assist in removal.
Access Cover
The macerator has an access cover that
can be removed to gain access to the
pumping and macerating cartridge to
remove debris or perform service. The
auxiliary inlet couplers, Allen wrench,
grease packet, clamps, and 9V battery
are shipped in the access cover
beneath the right access cover.
Preparation
The pump shall be plugged into a properly fused electrical
outlet with a ground fault circuit interrupter (GFCI) that
conforms to current National Electric Code (NEC) and all
applicable local codes. All wiring must be performed by
qualified personnel.
Pump shall be properly grounded using its supplied
grounding conductor. Do not bypass grounding wires or
remove ground prong from attachment plugs. Failure to
properly ground the pump system can cause all metal
portions of the pump and its surroundings to become
energized.
The electrical power supply shall be located within the length
limitations of the pump power cord, and for below grade
installations it shall be at least 4 ft (1.22 m) above floor level.

All pump/pump system installations shall be in compliance
with all applicable Federal, State, and Local codes and
ordinances.
Macerating unit must be located on same floor as connecting
fixtures.
Layout: The bathroom layout should be designed prior to
installation. Make certain the power source (GFCI receptacle) is
within range of the macerator’s 8 ft power cord. The GFCI
receptacle shall be 40 inches away (in a straight line) from a
shower or bathtub. For basement installation, the receptacle shall
be 48 inches from the floor.
Power Cord: The power cord can be configured to exit the unit on
either the left or right side. If the power cord will exit the left side
of the macerator, the vent flange must be removed so the cord
can be routed between the positioning clips. Reinstall vent flange
after routing the cord. Do not use an extension cord. If the
electrical power receptacle (outlet) is in close proximity to the
macerator, any extra power cord can be coiled and tucked away in
the access cover located under the right decorative cover.
Easy Access: The unit should be accessible and removable in the
event of required maintenance. During installation, a full port ball
valve should be installed near the discharge flange to allow easy
service of the unit. If possible, the right side of the macerator
should remain unobstructed. The access cover allows access to
the internal mechanisms. In the event of a jam, the decorative
cover as well as the access cover will need to be removed from the
macerator and working room to do so would be beneficial.
Water Supply: The water supply line for the toilet tank is located
on the left side. When roughing in, allow for the macerator.
Discharge: Never discharge directly into an open drain, fixture,
manhole or rainwater drainpipe. It is illegal, as it constitutes a
health hazard. Only direct connections into sanitary waste systems
shall be acceptable.
Auxiliary Ports: Auxiliary inlet ports are located on either side
toward the back of the macerator tank. These ports can accept
waste from sink or tub/shower. A sink should be plumbed into
one of the auxiliary inlets and not the discharge line of the
macerator even if elevations would allow such an installation. The
discharge line is pressurized and the plumbing system needs to
accommodate this.
Freezing: Ensure all pipework susceptible to freezing is adequately
insulated or heated. In unheated buildings, the toilet, piping, and
macerating unit must be properly winterized. Use plumbing
antifreeze or drain completely. The battery should also be
disconnected.
Discharge Extension: An optional discharge extension [P/N
K001184 sold separately] allows the macerator to be positioned
behind a wall. For example, the macerator could be positioned on
the floor of a linen closet or utility room. Do not fully frame unit
into a wall as access to macerator must be maintained.
Toilet Placement: The toilet hold down fasteners should be
located 16 inches from the wall and spaced 7 inches apart. This
assumes a typical baseboard of 3/4” x 5-1/2” with 3/4” quarter
round. Actual baseboard dimensions must be taken into account
during the installation and thus rough-in dimensions may change.
Tub/Shower: Water height will be 4½ inches in the macerator
tank before the unit starts pumping. A shower stall floor must be
well above this level. Liberty Pumps recommends at least 6–8
inches to ensure proper shower drainage and prevent any
backflow.
Figure 1. Typical Applications
Pipework: All pipework should be copper, PVC, or CPVC. Do not
use flexible piping. Support hangers should not be less than 4 ft
apart to prevent pipe rattling.
Pipe Supports: All sanitary pipework must be supported in
accordance with the pipe manufacturer’s recommendations.
Avoid dipping or trapping, which may cause the buildup of
residual solids and subsequent blockage.
Bends: Wherever possible, long sweeping bends should be used.
Do not use short elbows. If sweeping 90° elbows are not available,
use two 45° elbows to make a 90° turn.
Shut-off Head: The macerator has a shut-off head of 36 ft. All
frictional losses from horizontal runs and elbows need to be
accounted for. The minimum flow rate for 1” PVC Schedule 40
pipe is 5 gal/min compared to 3 gal/min for 3/4” PVC pipe.
RISK OF FIRE
RISK OF SERIOUS INJURY OR DEATH
Tub/shower should be installed on
a riser to accommodate the p-trap.
All fixtures must be properly vented per applicable local plumbing code.

5755000K Copyright © Liberty Pumps, Inc. 2020 All rights reserved. 7 | EN
Gravity Fall: The unit accepts wastewater by gravity; it does not
vacuum in water. All inlet pipework must have a positive gravity
fall (1/4 inch per foot drop minimum).
Vertical Lift: If vertical lift is required, this must precede the
horizontal pipe run. All vertical lifts should rise as close to the
macerator as possible, allowing only for the need to clear the
toilet tank. The initial horizontal run should not exceed 12 inches.
Once the horizontal run is started, do not change directions in a
vertical manner.
Discharge: All discharge piping from the unit should run either
directly vertical or in a horizontal plane (with a minimum 1/4 inch
per foot drop) to the point of discharge. Pipework must not be
installed with a diagonal upward slope from the unit to the point
of discharge. Long downward pitched runs of discharge piping, or
piping where the point of discharge is at a lower elevation than
the macerator unit, should be designed to prevent siphoning from
the macerator tank.
Friction: Friction losses from horizontal runs without 1/4 inch per
foot pitch will reduce the amount of vertical lift the system is
capable of handling. Refer to Figure 3. Consult factory for proper
sizing if there are long runs or multiple elbows.
Lift Calculations: To pump vertically and horizontally, calculate
3 ft of vertical lift as equivalent to 30 ft of horizontal run. Each
bend or change of direction gives a pressure drop, which must be
calculated into the total head of the unit. As an estimate, reduce
discharge height by 3 ft for each 90° bend.
For example: 1” Schedule 40
PVC pipe is used for the
discharge and runs
horizontally for 1 ft, then
turns 90°, and rises 5 ft
vertical. Then it travels
horizontal with another 90°
turn (3 turns in total) and
connects with the soil-stack.
Refer to Figure 2.
Calculations:
[A] Total vertical lift 5 ft= 5 ft
vertical
[C+D+E] Total horizontal run
43 ft = 4.3 ft vertical
[B] Total of three 90° elbows
= 9 ft vertical
Add the three calculation
totals together to get 18.3 ft
ofvertical head (lift).Referring
to Figure 3, the application
would result in a flow rate of
23 gal/min (60 Hz).
Figure 2. Example Calculations
Figure 3. Performance Curve
Macerating Unit Preparation
Auxiliary inlets should be plumbed using the supplied auxiliary
inlet couplings and/or reducing bushing when connecting to
either 2” or 1-1/2” standard Schedule 40 PVC pipe. A plug must be
removed by turning until the rib is vertical and pulling outward.
Pliers may be required if unit has been stored.
Both the discharge and vent flanges are shipped from the factory
in the horizontal orientation. If the installation allows for a vertical
orientation, the four screws must be removed from each in order
to flip the flange. The decorative cover will need to be modified
with the use of a hole saw and cutters to remove material. A
template is provided on the underside of the decorative cover.

Installation
The pump shall be plugged into a properly fused electrical
outlet with a ground fault circuit interrupter (GFCI) that
conforms to current National Electric Code (NEC) and all
applicable local codes. All wiring must be performed by
qualified personnel.
All electrical and safety practices shall be in accordance with
the National Electrical Code®, the Occupational Safety and
Health Administration, or applicable local codes and
ordinances.
Pump shall be properly grounded using its supplied
grounding conductor. Do not bypass grounding wires or
remove ground prong from attachment plugs. Failure to
properly ground the pump system can cause all metal
portions of the pump and its surroundings to become
energized.
Note to Installer: During installation, it is best to cover the
macerating unit with plastic to protect it from potential leaks at
the toilet fill connection or tank to bowl gasket.
Refer to Figure 1 Typical Applications as needed during the
installation process. Installations may vary per local plumbing and
electrical codes. Also, discharge and vent pipe routing can vary
per installation.
1. Place the macerator in the desired location and connect all
inlet and outlet waste piping to the unit. The inlet side should
be facing the toilet to ensure proper placement. Refer to
Figure 4 and Figure 5.
2. Assemble the toilet in accordance with the installation
manual(s) provided with it. Be careful when tightening
fasteners as to not crack the porcelain.
Figure 4. Placement Options
Figure 5. Toilet Connections
1. To mount the toilet to a concrete floor, drill two holes
approximately 2-1/4” deep with a 5/16” masonry drill bit.
Insert plastic plugs into holes. If the floor is wood, bore a pilot
hole with a 1/4” drill bit. Fasteners not included.
2. Toilet to macerator connection:
a. Standard Installation:
Place the toilet in front of the
macerating tank and apply
silicone grease (supplied) to the
rubber sealing lip of macerator.
Then slide the discharge hub of
the toilet into the rubber
sealing ring of the macerator.
b. Behind Wall Installation:
To install the macerator behind a wall, an Extension Pipe Kit
(K001184, sold separately) is needed. Included in the kit
are an 18-3/4” long extension pipe, a decorative trim ring,
and a grease packet. Rubber rings seal both ends of the
extension pipe.
To prevent tearing, always grease both seals prior to
installing the pipe. Slip the decorative trim ring onto the
pipe. To install the pipe, no fasteners are required. Slip the
extension pipe over the toilet discharge, and then insert
the pipe into the macerator.
Liberty Pumps recommends using only one extension pipe.

3. Place the toilet over the holes in the floor. Slip the plastic
china protectors over the lag screws ensuring proper
orientation. Tighten lag screws (do not overtighten) and snap
plastic caps in place.
For proper flushing performance, ensure that the base of the
toilet is not below the base of the macerator. Check the
extension pipe, if applicable, with a level, and verify that the
pipe is either level or sloped toward the macerator unit and
away from the toilet.
4. Connect the water supply line to the fill valve, located directly
below the flush lever, on the bottom of the toilet tank.
Connection to the Discharge and Vent Flanges
To finish the installation, fasten the toilet to the floor and secure
the macerator discharge and vent piping.
Do not use an air admittance valve or a mechanical
spring-loaded venting device, as these devices are one-way
valves. The air pressure in and outside the macerating pump
unit must be equal and a “cheater” vent will obstruct the
airflow in one direction and prevent proper toilet function.
Discharge Flange
The macerator has a PVC discharge flange with an integrated
check valve that can be configured in a horizontal or vertical
orientation. Standard 1” Schedule 40 PVC pipe can be solvent
welded directly to the flange.
Excessive amounts of glue should be avoided. The check valve can
be removed from the flange if required.
A full port ball or gate valve and a union should be installed in the
discharge pipe to facilitate the removal of the macerator or to
perform maintenance. Additionally, a drain off point is
recommended to allow the discharge piping to be drained.
Vent Flange
The macerator is equipped with a PVC vent flange, which can be
configured in a horizontal or vertical orientation. Standard 1-1/2”
Schedule 40 PVC pipe can be solvent welded directly into the
flange.
The macerator must be vented to allow for proper toilet flush
performance. Depending on the installation, the product should
either be connected to the stack vent of the dwelling or vented
(plumbed) directly outside. Vent in accordance with applicable
plumbing codes.
The macerator is not designed to support the discharge and vent
piping; proper pipe supports are required.
Connection to the Soil-stack or Sewer
The discharge piping can be made from 3/4” or 1” diameter PVC
pipe. Use long turn bends and avoid elbows where possible. The
connection to the soil-stack or sewer pipe must be made with an
approved connection, such as a T or Y fitting.
Operation
Decorative covers must be installed for operation as a safety
device is integrated into the covers to prevent unintended
operation. The unit may start when energized the first time.
The macerating system is designed for human waste and
toilet paper. Do not dispose of acids, alkalis, solvents, oils,
paint, paint strippers, food waste, and cotton swabs.
Off-the-shelf toilet cleansers will normally not hurt the
macerating unit.
During cleaning or when using a plunger, the macerator
could turn on.
Do not hang bleach blocks or hypochlorite cleaners in the
toilet tank. These solutions have been shown to deteriorate
the plastic and neoprene components of the flush and fill
valves, and may cause leaks.
In the event of a power loss, the toilet can be used twice. Use
of sanitary fixtures such as a sink should be limited. Do not
use shower or tub as the macerating unit will fail to pump
until the power is restored.
1. Ensure that the toilet and tank have been assembled per
instructions provided with the toilet tank.
2. Ensure any full port ball or gate valve in the discharge line is
in the open (full flow) position.
3. Open the shut-off valve and let the toilet tank completely fill.
Look for leaks at connections and verify that the toilet fill
valve float and the flush valve operate freely.
4. Ensure the macerating unit has both decorative covers
installed and is plugged in with the power supply turned on.
The green POWER LED should be illuminated steady.
a. If the green LED is blinking, confirm the decorative covers
are properly seated.
5. Battery: Battery must be
installed after the
macerator is connected to
the AC power supply.
If battery was
inadvertently installed
before power was applied:
a. unplug the macerator
from power source
b. remove the 9V battery
c. plug the macerator
back into the power
source
d. reinstall the 9V battery
6. Deposit a few sheets of toilet paper into the bowl and flush
the toilet. There should be no paper remaining in the bowl
after the flush. Repeat several times.
The unit will turn on shortly after the toilet is flushed or when
water depth is achieved. The duration of operation will differ
depending upon the installation. The macerator may not run
immediately on sink usage.
RISK OF SERIOUS INJURY OR DEATH

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

Cutter Blade Replacement
Wear Protective Personal Equipment to protect hands as
exposed cutter blades have sharp edges.
The cutter blades are designed and rigorously tested to last
indefinitely without need for service or replacement in ordinary
applications. In the unlikely event that the cutter blades need
replacement, Liberty Pumps recommends replacement kit
# K001370 (440A Stainless Steel Cutter Blades hardened to
Rockwell 54c) available from http://www.libertypumps.com/
Services/Replacement-Parts or equivalent substitute.
To replace the cutter blades, 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 cutter 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, exposing the two
cutter blades. Carefully insert the new cutter blade onto the two
pins. Replace the cap and screw.
The base of the cutting cartridge can be replaced as well. After
removing the cutter 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.
Accessibility to Motorized Cartridge
The motorized cartridge can be accessed through the access
opening or removal of the main cover.
Removal of Power Cartridge Through the Access Opening:
Once the access cover has been removed and the basket is slid
toward the opening, the four fasteners securing the basket can be
unscrewed. The basket can then be removed through the opening
followed by the power cartridge.
Removal of Power Cartridge by Disassembly of Macerator: If a
full port ball valve was installed in the discharge line, it should be
closed to eliminate the possibility of waste discharging from the
discharge pipe. Next, the discharge and vent flanges should be
separated from the main cover by removing 4 screws from each.
The main cover can then be detached from the tank by removing
the fasteners on the periphery of the tank. The main cover can
then be lifted upward exposing the power cartridge.
Power Cord: The inner connecting power cord running from the
switch box to the motorized cartridge can be detached by
unscrewing the compression nut located at the motorized
cartridge.

Impeller Access
Once the bottom of the
motorized cartridge is
accessible, the fasteners
retaining the volute can be
removed and the volute
separated by pulling it away. The
impeller chamber can now be
cleaned if required, or the
impeller can be replaced.
Note: the impeller has a
left-handed thread. To remove,
use a slotted screwdriver to hold
the shaft and turn the impeller
clockwise.
Control Switch
The control switch
cartridge is mounted to
the main cover with
fasteners. The control has
two power cords; first is
the main power cord that
plugs into the GFCI
receptacle and the other
powers the motorized
cartridge. The motorized
cartridge must be
removed to disconnect
this cord. Refer to
Accessibility to
Motorized Cartridge for
details.
