_" CAUTION
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
switcb
bits the side of the sump,
the switch
may stick and
prevent
pump
fi'om starting.
Make sure that pump
is se-
cured
so tbat it cannot
"walk around"
in sump.
NOTE: To avoid backflow
into tile sump when the pump
shuts off, install a Check Valve, SEARSStock No. 2789, in the
threaded discharge port of pump (390.303302) or l-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.
