GENERAL SAFETY INFORMATION:
THE FOLLOWING WARNINGS ARE USED TO NOTIFY AND ADVISE THE USER OF THIS PRODUCT OF
PROCEDURES THAT MAY BE DANGEROUS TO THE USER OR RESULT IN DAMAGE TO THE PRODUCT.
THIS BULLETIN MUST BE READ COMPLETELY BEFORE INSTALLING, OPERATING, OR SERVICING,
THE PUMP.
INSTALLATION:
Install the pump where the inlet is below the liquid level. A valve may be used to isolate the
pump for service. The pump is not self-priming and needs the inlet to be flooded at start-up.
The motor is splash resistant, not submersible, and should be located in a dry environment.
• DO NOT perform service or maintenance
when the pumping system is pressurized.
Injury or death may occur.
• DO NOT operate the pump in a manner
that it was not intended to be used.
• DO NOT mount the pump such that high
piping loads exist on the pump flanges, or
in a rigid piping system that does not allow
the pipe to expand and cause the pump to
be strained.
• DO NOT continue to operate the pumping
system when a known leak exists.
• DO NOT continue to operate the pump
when unusual noise or vibration occurs.
• DO NOT operate beyond the pressure or
temperature limits stated in the product
literature. See Form 8110.
• DO NOT allow severe temperature changes
to occur in a short time period within the
pumping system.
