2-9 NORMAL OPERATING CYCLE: The macerator’s IST switch is 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.
2-10 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; please see the trouble shooting guide to determine the cause and solution. A silence button located on the
user interface touchpad will stop the audible alarm. The alarm light will continue to illuminate. Discontinue using the product until the problem
has been identified and resolved. In the event of a power outage, a 9-Volt battery will power the alarm. (Note: In the event of a power outage
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. If the yellow light is illuminated on the LED touchpad, the 9 volt
battery needs to be replaced. The expected life of the supplied battery is 5 to 7 years.
2-11 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 maintenance. Once the right hand decorative cover and access cover have been removed, the cartridge can be slid towards
the opening to provide access to the basket and cutting mechanism. The blades or entire cutting base can be replaced if needed. See the
maintenance section 4-3 of this manual for detailed instructions.

NOTE: All installations should be done in accordance with federal, state and local codes. It is recommended that a certified or qualified
installer perform these operations. Do not use an air admittance valve or a mechanical spring-loaded venting device.
3-1 The bathroom layout should be designed prior to installation.
a) Make certain the power source (GFCI receptacle) is within range of the macerator’s 8’ power cord. The cord can be configured
to exit the unit on either the left or right side. Do not use an extension cord. When exiting 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.
b) If possible, the right side of the macerator should remain unobstructed. An access cover is located under the decorative cover
that allows access to the cutting mechanism. 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.
c) Auxiliary inlet ports are located on either side towards the back of the macerator’s tank. These ports can accept waste from
sink or tub/shower.
d) An optional discharge extension allows the macerator to be positioned behind a wall. For instance, the macerator could be
positioned on the floor of a linen closet or utility room. DO NOT fully frame unit into a wall -- access to macerator must be
maintained.
e) The macerator features Quickflip tm discharge and vent flanges that can be oriented in a vertical or horizontal orientation to best
fit your installation.
f) 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.
g) The water supply line for the toilet tank is located on the left side. When roughing in, pay attention to allow for the macerator.
h) 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.
i) Rough in dimensions – The toilet hold down fasteners should be located 16” from the wall and spaced 7” apart. This assumes
a typical baseboard of ¾” x 5.5” with ¾” quarter round. Actual baseboard dimensions must be taken into account during the
installation and thus rough in dimensions might change.
