1-2 STORAGE BEFORE USE
Liberty products are shipped from the factory ready for installation and use. If storage is necessary, the pump should remain in its shipping
container. It should be stored in a warehouse or other area that is clean, dry and temperature-stable. The pump and packaging should be
covered to protect it from water, dirt and dust.
IMPORTANT: After installation, do not allow the pump to freeze. If the home is allowed to freeze during winter months, ensure the macerating
unit and toilet are evacuated of water before closing the home. The tanks should be properly winterized and filled with plumber’s anti-freeze to
protect against freezing conditions. The battery should also be disconnected.
2-1 MACERATING SYSTEM: The macerator is designed to accept wastewater from a rear discharge toilet but can also simultaneously receive
wastewater from several sanitary fixtures like a sink, shower, bathtub, or urinal (a single bathroom group). However, only one water closet
(toilet) per unit may be connected.
2-2 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.
2-3 TOILET: The toilet works as a conventional flushing toilet and needs no special maintenance in normal use. All standard cleaners can be used
just as with a standard conventional toilet.
2-4 BATH LAYOUT: Sanitary fixtures connected to the macerating system must be located on the same floor level.
2-5 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. The plug can 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.
2-6 BATHTUBS AND SHOWER STALLS: Any regular bathtub up to 100 gallons or shower can be used. When installing these fixtures, build a 6” high
platform on which the fixture is placed. This gives enough space for a p-trap and slope toward the Macerator’s auxiliary inlets. When installing
a shower, manufacturers sometimes offer a pre-fabricated 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
¼” per foot drop.
2-7 OPERATION: 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. See Section 2-9 for normal
operating cycles.
2-8 USER INTERFACE: The macerator has a user interface (touchpad with LED’s) located on the top left side of the unit. This label contains three
LED lights: GREEN – identifies the unit has power, YELLOW – 9-volt battery needs to be replaced, and RED – alarm. If the unit is unable to
evacuate the holding tank or cannot keep up with the incoming flow the red light and audible alarm will activate. The label has two push
buttons – a “Push to Silence” which will silence the audible alarm and a “Push to Run” which will over-ride the internal switch and manually run
the macerator and pump.
