tional Electric Code and all local codes.
If there is a conflict between the instruc­
tions in the manual accompanying the
unit and the National Electric Code or
the applicable local code, the National
or local code shall take precedence.
If this pump is used with volatile and/or
flammable liquids, overheating may
produce dangerous fumes. Take pre­
cautions to ensure the area surrounding
the pump is adequately ventilated. Al­
low the pump to cool and use extreme
caution when venting the pump, or
when removing covers, plates, plugs, or
fittings.
Use lifting and moving equipment in
good repair and with adequate capacity
to prevent injuries to personnel or dam­
age to equipment. Suction and dis­
charge hoses and piping must be re­
moved from the pump before lifting.
After the pump has been installed, make
certain that the pump and all piping or
hose connections are tight, properly
supported and secure before operation.
Do not operate the pump without the
shields and/or guards in place over the
drive shaft, belts, and/or couplings, or
other rotating parts. Exposed rotating
parts can catch clothing, fingers, or
tools, causing severe injury to person­
nel.
Do not operate the pump against a
closed discharge valve for long periods
of time. If operated against a closed dis­
charge valve, pump components will
deteriorate, and the liquid could come
to a boil, build pressure, and cause the
pump casing to rupture or explode.
Overheated pumps can cause severe
burns and injuries. If overheating of the
pump occurs:
1. Stop the pump immediately.
2. Ventilate the area.
3. Allow the pump to completely cool.
4. Check the temperature before
opening any covers, plates,
gauges, or plugs.
5. Vent the pump slowly and cau­
tiously.
6. Refer to instructions in this manual
before restarting the pump.
Do not remove plates, covers, gauges,
pipe plugs, or fittings from an over­
heated pump. Vapor pressure within the
pump can cause parts being disen­
gaged to be ejected with great force. Al­
low the pump to cool before servicing.
Never run this pump backwards. Be cer­
tain that rotation is correct before fully
engaging the pump.
Pumps and related equipment must be in­
stalled and operated according to all na­
tional, local and industry standards.
