ADDITIONAL INSTALLATION

MATERIALS

SumpFLTtility Pump Hose Kit, SEARS Stock No. 27909, con- taining 24' of 1-1/4" flexible plastic pipe, a 1-1/4" plastic adapter and a stainless steel clamp.

Check Valve, SEARS Stock No. 2789 or 2792.

THE SUMP

The sump should be located at the lowest place in the base- ment or area to be drained. Floor drains from other areas in

the basement may be tiled into the sump. Drain tile around a house foundation can also be tried into the sump, effec- tively removing water and relieving pressure from this area. A suitable sump can be a 20" or 24" sewer tile. Sump must be at least 12" in diameter.

A sump cover is desirable to exclude refuse from the sump. Consult local code for sump cover specifications.

PUMP INSTALLATION

Check your local Electrical and Plumbing Codes before in- stalling pump. You must comply with their rules.

Set the pump on the bottom of the sump, making sure that it sits solidly and is level. Be sure there is enough space around the pump to allow the switch free movement as the sump water level changes. Do not install on clay, earth, or sand.

[A _Risk of flooding. If a flexible discharge

hose is used, pump may move around in sump when motor starts. If it moves far enough so that the

switch hits the side of the sump, the switch may stick and prevent pump from starting. Make sure that pump is se- cured so that it cannot "walk around" in sump.

NOTE: To avoid backflow into the sump when the pump shuts off, install a Check Valve, SEARSStock No. 2789, in the

threaded discharge port of pump (390.303302) or 1-1/2"xl- 1/4" reducer bushing (390.303491). Reducer bushing is in- cluded with Model 390.303491. Be sure arrow on check valve body points away from the pump. This Check Valve is

equipped with an air bleed hole to prevent airlocking the pump. If using any other check valve, drill 1/8" (3.2 ram)

hole in discharge pipe just above pump body but below check valve to prevent air locks.

Use 1-1/4" plastic pipe from Hose Kit No. 27909 for the dis- charge pipe. Run the discharge pipe to the nearest sewer outlet or other point of disposal. Use the most direct route with the fewest turns and elbows possible.

Use Teflon tape to seal threads in plastic pipe. Hand tighten only.
