In damage to internal components.

hole and insert the grommet. Slide the 2" PVC drain line into the pipe

grommet, lubricating the pipe if necessary to ease installation.
Note: If installing a washing machine, the preferred method would be to

drain washer into a tub sink with a lint sock prior to the LowPro. Also,

periodically remove access cover and clean lint and debris off of switch

NOTE: Threaded connections at tank - HAND TIGHTEN ONLY. Use

Teflon tape as a thread sealant. Install a 2" PVC pipe to the connection

labeled "Discharge". Attach the 2” check valve (Fig. 8, item 14) to the

discharge pipe as close to the top of the tank as possible. Make sure

that the arrows on the check valve are pointing up, away from the pump.

Do not reduce the discharge pipe size below 2".

7. Complete the discharge piping to the house waste line using a minimum

number of turns. See "Note" under Pump Specifications for maximum

head performance of the LowPro system.

Install a 2" vent pipe into the vent opening on the cover. Connect

the vent pipe to the house vent line or directly to the atmosphere.

Unit must be vented directly to the atmosphere in accordance with

national and local plumbing codes. DO NOT use an automatic or

mechanical vent device.

9. If you are not installing a finished floor above the LowPro tank system,

skip steps 10 through 12, and resume installation at step 13.

10. The rough opening size required for installation using standard 2”X6” floor

joists will vary depending on your actual installation and the orientation of

the tank. The overall rough opening size needed to enclose the entire

LowPro tank is 42” X 24½”.

11. Measure the finished flooring thickness and determine the number of closet

flange spacers (Figure 8, item 17) needed to bring the closet flange up to

the finish floor. See Figure 6.

12. Set the proper number of plastic closet flange spacers (as determined in

step 11) onto the brass closet flange. The foam gasket material on the

spacer(s) must be facing down. The spacer(s) will not be secured to the

closet flange, so use care not to move them during the installation of the

toilet.

13. Install the wax toilet bowl seal ring provided onto the toilet following the

directions included with the toilet. Install the toilet onto the closet flange

following the directions included with the toilet. Hook up the water line to

the toilet. Turn the water on and fill the toilet tank. Test for leaks. Flush

the toilet several times and allow the pump to cycle to ensure proper

operation.

NOTE: The LowPro features an internal jet spray to help break down solids

and reduce jamming. Due to limited water volumes per pump cycle on

systems of this type, care must be taken to avoid flushing extreme amounts

of toilet paper or any reinforced papers, paper towels, sanitary products and

other foreign objects into the LowPro.
