Installation (continued)
13. Assemble the union. Make sure that the elbow/check valve alignment with existing plumbing is correct.
14. Install a 2 in. or 3in.vent pipe (check your local plumbing code) in the 3 in.NPT threaded vent port on the pump chamber. You can use
a 3 in. threaded pipe or glue the vent pipe to a male adapter (3 in. vent pipe)or 2 in. slip x 3 in.NPT reducer bushing (2 in. vent pipe),and
then thread the assembly into the vent port on the pump chamber.
15. Connect the discharge pipe and vent pipe into the house plumbing.
CAUTION: Risk of flooding. Vent this unit directly to atmosphere (or through the existing house vent pipe) according to national and
local plumbing codes. An automatic or mechanical vent device will not work with this system. The toilet will not flush unless properly
vented.
16A. If you are not attaching any additional fixtures to the unit, skip to Step 20. If an additional fixture is being added to your installation,
go to Step 16B.
16B. Mark the center of a 3 in. diameter hole on one of the three sides of the pump chamber.
NOTE: The center of this hole must be at least 6-1/2 in. above the bottom of the tank, as shown in Figure. 6. If you intend to add more than
one extra fixture, mark a hole center as above for each additional drain line. Each center must be at least 6-1/2 in. above the bottom of the
tank.
17. After choosing the spot(s) for the hole(s), lightly center punch hole centers on the pump chamber.
18. For each center you have marked, cut a 3 in. diameter hole with a hole saw.
NOTE: To avoid leaks, the hole’s maximum diameter must be 3 in. Do not go oversize.
19. Lubricate a 2 in. pipe grommet with soapy water and push it into the 3 in. hole from Step 18. Lubricate the fixture drain pipe and push
it through the pipe grommet into the pump chamber. The pipe must not interfere with the operation of, nor touch, the pump or switch.
Repeat for all drain lines.
WARNING: Risk of electrical shock. Make sure the pump is unplugged before beginning step 20.
20. Fill the tank to a depth of approximately 4 in. (check this with a tape measure through the opening where the toilet is to be installed).
Plug in the pump and continue filling the tank.
The pump must start when the water level is between 3-1/4 in. and 4-1/2 in..
21. Check the tank for leaks. Attach the cord to the discharge or vent pipe. Do not leave excess cord inside the tank, as it may interfere
with the pump's operation.
