Pump Installation
These important instructions
must be followed for
satisfactory performance
of your pump. Before
installation, check your local
electrical and plumbing codes.
1. Provide proper sump size
to allow the pump to
operate without
restrictions. A two- to
five-minute run time is
recommended. Also,
minimum 24" diameter
recommended.
2. Make sure sump is free of
string, cloth, nails, gravel,
etc. before installing pump.
3. Do not set pump directly
on the bottom of sump pit
if it is not solid. Raise the
pump by placing bricks or
concrete blocks underneath
it.
4. Use steel or plastic pipe
for all connecting lines
between pump and sewer
outlet.
NOTE: Some city
regulations do not allow
installing a pump with
plastic pipe. Check local
regulations.
5. In applications where
the pump may sit idle for
months at a time, it is
recommended that the
pump(s) be cycled every
month to ensure the
pumping system is working
properly when needed.
6. A check valve should be
installed in discharge
pipe, at least 12" above
the discharge outlet of the
pump.
NOTE: If pumping raw
sewage, the check valve
must be installed in the
horizontal position
7. An audible alarm system,
for high water conditions
should be installed in
every pump for greater
protection.
8. Connect to power source
using 3-prong grounded
AC receptacle. Do not
remove ground pin from
electrical plug. Do not use
an extension cord.
9. Use pump partially or
completely submerged for
pumping (temperature to
140° F). The MSE50 will
pump solid materials up to
2" (spherical) in diameter.
CAUTION: Do not pump
flammable liquids, strong
chemicals or salt water.
