Assembly / Installation

IMPORTANT: To prevent leaks, be sure that the cleats on the corners of the basin gasket are up with the cover upside down (that is, not pressed into the sealing face of the cover).

Step 7 (See Figure 5)

Push the screws with their washers installed up through the holes in the rim of the cover and in the basin gasket (the cover will retain the screws).

Step 8 (See Figure 6)

•Align the cover with the discharge pipe and cords.

•Pull the cords through the non-threaded hole in the basin cover.

•Place the cover over the discharge pipe.

•Install the cords in the cord grommet

•Install the cord/grommet assembly in the non-threaded hole in the basin cover; don’t pull the cords tight.

Step 9 (See Figure 6)

Fasten the basin cover to the basin with the capscrews previously inserted in the cover (Step 7).

IMPORTANT: To prevent leaks, be sure the locating cleats on the corners of the basin gasket are outside the edges of the basin rim, not pressing against the rim.

INSTALLATION (See Figure 7)

The basin (system) should be located at the lowest place possible relative to the area to be drained.

NOTE: Make sure that the inlet of the pre-plumbed system is lower than the water to be pumped.

Thread pipes into fittings; don't go past end of threads.
