Submersible Pump Safety
DANGER
!
• Do not use to pump flammable or explosive flu-
ids such as gasoline, fuel oil, kerosene, sol-
vents, thinners etc. Do not use in a flammable
and/or explosive atmosphere. Pump should
only be used to pump clear water. Improper use
could result in personal injury and/or death.
WARNING
!
• If there is water or moisture on the floor or
ground near the pump, do not walk on wet area
until all power is turned off. If the shut-off box
is in the basement, call an electrician. Failure to
follow this warning could result in fatal electrical
shock.
• Always disconnect the power source before
attempting to install, service, relocate, or main-
tain the pump. Never handle a pump or pump
motor with wet hands or when standing on wet
or damp surface or in water. Failure to follow this
warning could result in personal injury and/or
death.
• Pump motor is equipped with automatic reset-
ting thermal protector that could restart unex-
pectedly. Disconnect power source when servic-
ing pump.
• Do not modify float or position float switch so
that pump will operate continuously. Pump is
not designed for continuous operation, this will
reduce performance and life of the pump.
• Do not hang pump by handle for permanent
installation. This minimizes twisting which can
lead to damage during pump operations.
