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.

Do not modify the pump/pump system in any way.
Modifications may affect seals, change the electrical loading
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.
