Gorman-Rupp Pumps 11 1/2A3-E2 1P 1045642 and up - Manual (Page 7)

10 SERIES OM-04091
PAGE A - 2 SAFETY
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.
Do not install and operate a non‐explo­
sion proof motor in an explosive atmo­
sphere. Install, connect, and operate
the motor in accordance with the Na­
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.
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.
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.
