SAFETY
the applicable local code, the National
or local code shall take precedence.
Because this pump is designed to han-
dle volatile and/or flammable liquids,
overheating may produce dangerous
fumes. Take precautions to ensure the
area surrounding the pump is ade-
quately ventilated. Allow the pump to
cool and use extreme caution when
venting the pump, or when removing
covers, plates, plugs, or fittings.
After the pump has been positioned,
make certain that the pump and all pip-
ing connections are tight, properly sup-
ported and secure before operation.
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.
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.
The electrical power used to operate
this pump is high enough to cause inju-
ry or death. Obtain the services of a qu-
alified electrician to troubleshoot, test
and/or service the electrical compo-
nents of this pump.
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.
Pumps and related equipment must be in-
stalled and operated according to all na-
tional, local and industry standards.
