provided to familiarize yourself with specific details regarding installation and use. These materials
should be retained for future reference.
PREINSTALLATION CHECKLIST - ALL INSTALLATION
CAUTION
SEE BELOW FOR LIST OF CAUTIONS
SEE BELOW FOR LIST OF WARNINGS
1.
Check to be sure your power source is capable of handling the
voltage requirements of the motor, as indicated on the pump
name plate. (See Fig. 2)
2
.
See DO’S and DON’T’S on last page of installation instruction
that will help assure longer pump life.
3
. If pump is used with variable level float control switch, it is the
responsibility of the installing party and care should be taken
that tethered float switches will not hang up on the pump ap
-
paratus or pit peculiarities and is secured so that the pump will
shut off at the proper level.
4
. Pump should be checked frequently for debris and/or build up
of deposits on both the inside and outside of the pump.
5
. Maximum continuous operating temperature for standard model
pumps must not exceed 130°F.
6
. Pump must operate totally submerged to the top of the motor
housing.
7
.
Information - vent hole purpose.
It is necessary that all
submersible sump, effluent, and sewage pumps capable of
handling various sizes of solid waste be of the bottom intake
design to reduce clogging and seal failures. If a check valve
is incorporated in the installation, a vent hole (approx. 3/16")
must be drilled in the discharge pipe below the check valve
and pit cover to purge the unit of trapped air. Trapped air is
caused by agitation and/or a dry basin. Vent hole should be
checked periodically for clogging. The vent hole on a High
Head application may cause too much turbulence. You may
not want to drill one. If you choose not to drill a vent hole, be
sure the pump case and impeller is covered with liquid before
connecting the pipe to the check valve and no inlet carries air to
the pump intake.
NOTE: THE HOLE MUST ALSO BE BELOW
THE BASIN COVER AND CLEANED PERIODICALLY. Water
stream will be visible from this hole during pump run periods.
1. Make sure the terminal or control box
is properly grounded
and contains a grounding lug for the pump. All pumps are fur
-
nished
with provisions for proper grounding to help protect you
against the possibility of electrical shock. Outside installation
require a NEMA 3R or 4X enclosure per the NEC.
2
.
Make sure the pump electrical supply circuit is equipped
with fuses or circuit breakers of proper capacity.
A sepa
-
rate branch circuit is recommended, sized according to the
“National Electric Code” for the current shown on the pump
name plate.
3
.
For your protection, always disconnect the pump from its
power source before handling.
4
.
Testing for ground. As a safety measure, each electrical outlet
should be checked for ground using an Underwriters Laboratory
Listed circuit analyzer which will indicate if the power, neutral
and ground wires are correctly connected to your outlet. If they
are not, call a qualified licensed electrician.
5
. Do not use extension cords. If a splice is required, a watertight
junction box must be used.
6
.
All single phase and three phase pumps must be wired and
grounded in accordance with the National Elec Code and all
applicable local codes and ordinances. All three phase pumps
require motor starting devices with motor overload protection.
See FM0514 for simplex or FM0416 for duplex installations.
Agriculture pumps are not to be installed in locations classified
as hazardous in accordance with the National Electric Code
ANSI/NFPA 70.
7
.
“Risk of electrical shock.”
Do not remove power supply cord
and strain relief or connect conduit directly to the pump.
8
. Installation and checking of electrical circuits and hardware
should be performed by a qualified licensed electrician.
REFER TO WARRANTY ON PAGE 2.
The Model 4290 and 4291 Agricultural Pumps are designed for pumping water containing animal waste with solids up to 1½".
