OPERATION - SECTION C
GENERAL INFORMATION
Review all SAFETY information in Section A.
This pump is not designed to pump vol­
atile, flammable, or corrosive liquids.
The maximum temperature of the liquid
being pumped should not exceed 104
_F
(40
_C); do not apply the pump at higher
temperatures. Do not attempt to pump
any liquids which may damage the
pump or endanger personnel as a result
of pump failure.
Follow the instructions on all tags, labels and de­
cals attached to the pump.
Pump Performance
Refer to the pump Specification Data Sheet for the
specific performance for your pump.
Control Box
The motor powering this pump is ap­
proved by either CSA and/or FM for
Class 1, Division 1, Groups C and D en­
vironments. Refer to the nameplate on
your pump for agency approval inform­
ation. Any liquid level devices used with
the pump must be intrinsically safe for
use in these environments
Any control box used to operate the
pump must meet all applicable local
and national codes for the application.
If the control box is to be installed in an
explosive environment, it must be a
Nema 7 rating or better. If a non‐explo­
sion proof control box is used, it must be
located outside the explosive environ­
ment. Improper location of a non‐explo­
sion proof control box could result in de­
struction of equipment, injury, or death
to personnel.
See the operating instructions furnished with the
control box, and with other optional accessories
and controls, before attempting to start the pump.
PUMP OPERATION
Liquid Temperature and Overheating.
Overheated pumps can cause severe
burns and injury. If the pump becomes
overheated:
1. Stop the pump immediately.
2. Lock out the power to the control
panel to ensure that the pump will
remain inoperative.
2. Allow the pump to completely cool
if overheated.
3. Close the discharge valve (if
used).
4. Refer to instructions in this manual
before restarting the pump.
Overheating can occur if the pump is misapplied;
if it is started more than 10 times within one hour;
if the control box fails to provide overload or ther­
mal protection, or if the pump is operated against
a closed discharge valve for an extended period of
time.
The submersible motor is cooled by the liquid be­
ing pumped. To minimize the chance of over‐heat­
ing when installed in a simplex application, it is
recommended that at least one‐half of the motor
remain immersed in the liquid.
