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.
