PUMP INSTALLATION

When installing or servicing the pump
or controls, follow all requirements for
the installation of wiring or electrical
equipment in hazardous locations as
outlined in the National Electric Code.
When entering the pump wet well for in­
stallation or service, follow all safety re­
quirements for confined space entry.
Failure to observe these requirements
could result in injury or death to person­
nel.

Do not allow the free end of the power
cable to enter the liquid being pumped.
The free end of the cable must be kept dry
to prevent liquid from wicking through the
cable and into the motor.

NOTE

Refer to the performance curve on the pump Spe­
cification Data Sheet
when determining the most ef­
ficient piping installation. The recommended
maximum submergence depth is 65 feet.

Lifting

Death or serious personal injury and
damage to the pump or components
can occur if proper lifting procedures
are not observed. Make certain that
hoists, chains, slings or cables are in
good working condition and of suffi­
cient capacity and that they are posi­
tioned so that loads will be balanced
and the pump or components will not be
damaged when lifting. Do not attempt to
lift this pump by the motor or control
cables, or the piping. Attach proper lift­
ing equipment to the lifting bail fitted on
the pump. Lift the pump or component
