CAUTION
SEE BELOW FOR LIST OF CAUTIONS
1. This pump is designed for handling clear water. Do not use in
septic tanks to pump effluent or sewage pits to pump sewage.
2. Repair and service of your backup system should be performed
by an authorized service station.
3. The installation of this backup pump requires the use of a
variable level float switch for operation. It is the responsibility
of the installing party, to ensure that the float switch will not
hang up on the pump apparatus or pit peculiarities and is
secured so the pump will turn "on" and "off". It is recommended
that the pit be 18" in diameter or larger to accommodate both
a primary and a backup pump.
4. Check the installation of the primary and backup pump floats
to ensure that both move freely and are not being encroached
upon where the float cannot move. Adequate space between
the floats must be maintained.
5. The pump should be manually activated once a month by
lifting the float rod. Let the pump run for at least 15 seconds
to prevent the pump from building up calcium deposits and
debris, which could harm the pump.
