SAFETY - SECTION A
This information applies to 0 Series
electric motor driven pumps. Refer to
the manual accompanying the motor
before attempting to begin operation.
This manual will alert personnel to
known procedures which require spe­
cial attention, to those which could
damage equipment, and to those which
could be dangerous to personnel. How­
ever, this manual cannot possibly pro­
vide detailed instructions and precau­
tions for each specific application or for
every situation that might occur during
maintenance of the unit. Therefore, it is
the responsibility of the owner, installer
and/or maintenance personnel to en­
sure that applications and/or mainte­
nance procedures not addressed in this
manual are performed only after estab­
lishing that neither personal safety nor
pump integrity are compromised by
such applications or procedures.
Before attempting to open or service the
pump:
1. Familiarize yourself with this man­
ual.
2. Disconnect the incoming power to
the motor and lock it out to ensure
that the pump will remain inopera­
tive.
3. Allow the pump to completely cool
if overheated.
4. Check the temperature before
opening any covers, plates, or
plugs.
5. Close the suction and discharge
valves.
6. Vent the pump slowly and cau­
tiously.
7. Drain the pump.
This pump is designed to handle clean
liquids that do not contain large en­
trained solids. Do not attempt to pump
volatile, corrosive, or flammable materi­
als which may damage the pump or en­
danger personnel as a result of pump
failure.
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.
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
