Installation
The upflush system can be installed as a free-standing unit or it can be enclosed.
1. Determine the location of the upflush system. Make sure you will have access to the existing discharge and vent lines. Make the
necessary measurements, and determine the necessary fittings and piping that are required. Be sure to observe all local plumbing codes.
2. Put the tank in position. It must be level to within1/8 in. over its entire length. Make sure that nails, screws, or other sharp objects do not
puncture the tank.
3. For an enclosed installation, the flat portion of the tank is 5-3/8 in. high, so it will fit between 2 in. x 6 in. floor joists. Note that you will
need to cut one joist (with 16 in. centers) and put headers in to accommodate the 24-1/4 in. width of the tank.
NOTE: A floor-flange-extender seal kit (purchase separately) must be used for this type of under-floor installation.
Figure 2: Center the pump discharge under the discharge
grommet in the lid; make sure the switch does not hit the
baffle in the tank.
4. Set the pump in the pump chamber with the discharge toward the right back corner as viewed from the toilet opening (see Figure 2).
Line up the pump discharge with the 3 in. hole in the tank lid, then swing the pump so that the vertical float switch is shielded (from
solids) as much as possible by the baffle in the tank between the toilet mounting hole and the pump chamber (see Figure 2). Shim the
pump as required to make it steady in the pump chamber.
5. Apply the foam gasket (see Repair Parts, Key No. 5)to the flange of the pump chamber. For best results, overlap the ends of the gasket
about 1/2 in..
6. Place the pipe grommet in the 3 in. hole in the pump chamber lid; this is the discharge seal. See Figure 3 for correct orientation.
7. Lubricate the pipe grommet with soapy water and push the discharge pipe (2 in. x 32 in.) through it.
8. Install the lid on the tank as follows:
A. Push the 2 in. discharge pipe down until approximately 16 in. projects down through the lid.
B. Glue on the adapter.
C. Pull the pump and switch power cords up out of the pump chamber and hang them over the edge of the chamber.
D. Screw the threaded adapter into the pump discharge by rotating the lid assembly until it is hand tight.
E. Thread the pump and switch power cords up through the 2-1/2 in. hole in the lid.
