PAGE A - 1 SAFETY
SAFETY ‐ SECTION A
This information applies to 80 Series
electric motor driven pumps. Refer to
the manual accompanying the motor
before attempting to begin operation.
Because pump installations are seldom
identical, this manual cannot possibly
provide detailed instructions and pre­
cautions for each specific application.
Therefore, it is the owner/installer's re­
sponsibility to ensure that applications
not addressed in this manual are per­
formed only after establishing that nei­
ther operator safety nor pump integrity
are compromised by the installation.
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 water
and most water‐soluable herbicides
and pesticides, as well as certain chem­
icals and waste solutions within speci­
fied temperatures and concentrations.
Do not attempt to pump volatile or flam­
mable materials which may damage the
pump or endanger personnel as a result
of pump failure.
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 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.
This pump is designed to handle materi­
als which could cause illness or injury
through direct exposure or emitted
fumes. Wear protective clothing, such
as rubber gloves, face mask and rubber
apron, as necessary, before discon­
necting or servicing the pump or piping.
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.
