Obtain the services of a qualified elec­
trician to troubleshoot, test and/or ser­
vice the electrical components of the
control box.
Before attempting to open or service the
pump:
1. Familiarize yourself with this man­
ual.
2. Lock out the power from the con­
trol box to ensure that the pump
will remain inoperative.
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 may be equipped with an op­
tional automatic starting system, and
therefore subject to automatic restart.
Keep hands and clothing away from the
unit to prevent injury during automatic
operation. Lock out the power from the
control box to ensure that the pump will
remain inoperative. Failure to do so
may result in serious personal injury.
Do not attempt to disengage any part of
an overheated pump unit. Vapor pres­
sure within the pump casing can eject
these parts with great force when they
are disengaged. Allow the pump to
completely cool before servicing it.
This pump is designed to handle most
non‐volatile, non‐flammable liquids
containing specified entrained solids.
Do not attempt to pump volatile, corro­
sive, or flammable liquids which may
damage the pump or endanger person­
nel as a result of pump failure.
Death or serious personal injury and
damage to the pump or components
can occur if proper lifting procedures
are not observed. Make certain that
hoists, chains, slings or cables are in
good working condition and of suffi­
cient capacity and that they are posi­
tioned so that loads will be balanced
and the pump or components will not be
damaged when lifting. Suction and dis­
charge hoses and piping must be re­
moved from the pump before lifting. Lift
the pump or component only as high as
necessary and keep personnel away
from suspended objects.
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. If operated
against a closed discharge valve, pump
components will deteriorate, and the
liquid could come to a boil, build pres­
sure, and cause the pump casing to rup­
ture or explode. Momentary closure of a
