1. Carefully unpack toilet and place it in the approximate position intended. Assure that adequate
clearance is available for opening the seat and lid. Check the front and sides of the toilet to
insure that it will set flat against the floor.
2. Insert 0.75-in. (19 mm) spacer between toilet and wall, and reposition toilet against spacer
(fig. ), making sure back of toilet is parallel to back wall.
1
3. Mark floor at the bottom front of toilet (fig.
mounting template where toilet was originally positioned, aligning front edge of template with
mark on floor representing front edge of toilet.
Note
Choose an inlet configuration for the electrical
wiring and water lines - through the rear wall or
through the floor. Refer to the Through-the-Wall
Diagram (shown at right) to plan access holes if
that is the intended application.
4. Mark all hole centers through template (fig.
mark the locations of the corners of the toilet mounting
brackets.
5. Remove template from floor. Drill all access and fastener holes as indicated on template
(fig. ). If electrical wires and water supply are being routed through the wall, be sure to drill
4
those holes through the wall.
6. Determine the best location for the flush switch panel. It is recommended that the flush switch
be near the toilet but not hidden by the toilet lid in the "up" position. Avoid a location susceptible
to direct water spray. Cable provided with flush switch must reach from switch location to con-
nection in toilet base. Follow instructions provided with flush switch to create access hole in wall.
7. Using PVC primer and solvent cement, solvent weld the desired outlet fittings to the discharge
adapter (fig. ). Allow to cure before handling.
5
8. Mount discharge adapter to the floor (fig.
the plumbing to vacuum tank or vacuum generator. Use 1.5-inch OdorSafe Plus flexible sanita-
tion hose or 1½-inch PVC schedule 40 pipe.
9. Route 0.5-inch (13 mm) diameter water line from the fresh water source through the 1-inch
(25 mm) hole in the wall or floor and attach a 0.5-inch NPT fitting (fig.
Note
An accessible shut-off valve should be placed in the water line to the toilet for maintenance
or repair.
10. WITH ELECTRICAL POWER OFF, route electrical cables/wiring from vacuum generator and
power source through wiring access hole (fig.
model's parts list. If wiring connector shown here is not being used, refer to wiring diagram to
make proper connections).
11. Install flush switch according to its instructions and route electrical cable through the wiring
access hole at the toilet (fig. ). Leave enough cable to connect to toilet. The cable supplied
7
with the VacuFlush switch should have ethernet cable connectors (not shown here).
12. Secure the toilet mounting brackets to the floor using the #14 x 2.5-inch (65 mm) hex washer
head screws provided (fig. ). Be sure to mount the brackets as shown on the template.
8
Note
Do not completely tighten hex-head screws to floor – allow brackets to slightly
slide. Brackets will tighten when fastening toilet to brackets.
13. Set the toilet in front of the discharge adapter. Connect the flexible water hose to the 1/2-inch
NPT fitting on the inlet water line. Connect the cable/wiring from vacuum generator and power
source to the toilet's vacuum generator-power source cables/wiring (fig.
cable from the flush switch to the circuit board located in the toilet's base (fig.
Caution!
DO NOT ATTEMPT TO SLIDE TOILET OVER THE FLANGE ADAPTER. THE TOILET MUST
BE SET DOWN INTO THE DISCHARGE ADAPTER TO PREVENT POSSIBLE DAMAGE.
14. Lubricate the O-ring around the bottom of the toilet base with silicone grease. Pick up the toilet
and insert plastic toilet base assembly into discharge adapter (fig.
brackets on floor do not interfere with bottom of ceramic toilet, and that toilet sits flat on floor
(fig. ). If the mounting brackets interfere, adjust bracket position accordingly.

15. Making sure that toilet mounting holes align with brackets, insert the two plastic flange bushings
into the toilet mounting holes and secure the toilet to the mounting brackets with the two flat
head wood screws provided (fig.

16. Press the decorative screw covers over the flange bushings (fig.
