required for a permanent installation. If flexible dis-
charge hose is temporarily used, make sure pump is
secured in sump pit to prevent movement. Failure to
secure pump could allow pump movement and cause
switch interference and prevent pump from starting or
stopping. This could result in flooding and property
damage.
IMPORTANT! Make sure there is adequate room for
float switch to move freely during operation. A 1"
minimum is required.
