CAUTION

LIST OF CAUTIONS

LIST OF WARNINGS
1. Make certain that the receptacle is within the reach of the pump’s power supply cord.
DO NOT USE AN EXTENSION CORD. Extension cords that are too long or too light do not
deliver sufficient voltage to the pump motor, and they could present a safety hazard if the
insulation were to become damaged or the connection end were to fall into a wet or damp
area.
2.
Make sure the pump electrical supply circuit is equipped with fuses or circuit breakers
of proper capacity.
A separate branch circuit is recommended, sized according to the
“National Electrical Code” for the current shown on the pump nameplate.
3.
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.
4.
For Added Safety.
Pumping and other equipment with a 3-prong grounded plug must be
connected to a 3-prong grounded receptacle. For added safety the receptacle may be
protected with a ground-fault circuit interrupter. When a pump needs to be connected in
a watertight junction box, the plug can be removed and spliced to the supply cable with
proper grounding. For added safety this circuit may be protected by a ground-fault circuit
interrupter. The complete installation must comply with the National Electrical Code and
all applicable local codes and ordinances.
5.
FOR YOUR PROTECTION, ALWAYS DISCONNECT PUMP FROM ITS POWER SOURCE BEFORE
HANDLING.
Single phase pumps are supplied with a 3-prong grounded plug to help protect
you against the possibility of electrical shock.
DO NOT, UNDER ANY CIRCUMSTANCES,
REMOVE THE GROUND PIN.
The 3-prong plug must be inserted into a mating 3-prong
grounded receptacle. If the installation does not have such a receptacle, it must be changed
to the proper type, wired and grounded in accordance with the National Electrical Code
and all applicable local codes and ordinances. Three phase pumps require motor starting
devices with motor overload protection. See FM0486 for duplex installations.
6. The tank is to be vented in accordance with local plumbing code. Pumps
must
be installed in
accordance with the National Electrical Code and all applicable local codes and ordinances.
Pumps are not to be installed in locations classified as hazardous in accordance with
National Electrical 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 servicing of electrical circuits and hardware should be performed by a
qualified licensed electrician.
9. Pump installation and servicing should be performed by a qualified person.
10. Risk of electrical shock - These pumps have not been investigated for use in swimming
pool and
marine areas.

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.
2. The installation of automatic pumps with variable level float switches or nonautomatic pumps
using auxiliary variable level float switches is the responsibility of the installing party and
care should be taken that the tethered float switch will not hang up on the pump apparatus
or pit peculiarities and is secured so that the pump will shut off. It is recommended to use
rigid piping and fittings and the pit be 18" (46 cm) or larger in diameter.
3.
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" [5 mm]) 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 53
®
/ 57, and
98 Series pumps have a vent located in the pump housing opposite the float, adjacent to
a housing lug, but an additional vent hole is recommended. 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.
4. Pump should be checked frequently for debris and/or buildup which may interfere with
the float “on” or “off” position. Repair and service should be performed by Zoeller Pump
Company Authorized Service and Warranty Center.
5. Dewatering and effluent sump pumps are not designed for use in pits handling raw sewage.
6. Maximum operating temperature for standard model pumps must not exceed 130 °F (54
°C).
7. Pump models 266, 267, and 137 must be operated in an upright position. Do not attempt to
start pump when tilted or laying on its side.
8. Do not operate a pump in an application where the Total Dynamic Head is less than the
minimum Total Dynamic Head listed on the Pump Performance Curves.
REFER TO WARRANTY ON PAGE 2.
NOTE: Pumps with the “UL” mark and pumps with the “US” mark are tested to UL Standard
UL778. CSA Certified pumps are certified to CSA Standard C22.2 No. 108.

* Effluent systems should specify that pumps should not handle solids exceeding 3/4” (19.1 mm) in order to prevent large solids from entering leeching fields, mound systems, etc. (Model 49
Series has 3/8” [9.5 mm] solids capability. 50, 90, and 151 Series have 1/2” [12.7 mm], 130 Series has 5/8” [15.9 mm], 152 and 153 models have 3/4” [19.1 mm].) Where code permits, sewage
pumps can be used for effluent systems. Nonautomatic pumps with external-level controls are recommended for septic tank effluent applications.
