PREINSTALLATION CHECKLIST - ALL INSTALLATIONS
1.
Inspect your pump. Occasionally, products are damaged during shipment. If the unit is damaged, contact your dealer before using. DO NOT remove the test plugs in the cover nor the
motor housing.
2. Carefully read the literature provided to familiarize yourself with specific details regarding installation and use. These materials should be retained for future reference.
1. Make sure there is a properly grounded receptacle available. All pumps are furnished
with provisions for proper grounding to protect you against the possibility of electrical
shock.
2. Make certain that the receptacle is within 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.
3. 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.
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. 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.
6. 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 FM1596 for simplex installations or FM0486 for
duplex installations. 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 electric shock. These pumps have not been investigated for use in swimming pool
areas.

CAUTION
1. Check to be certain your power source is capable of handling the voltage requirements of
the motor, as indicated on the pump name plate.
2. Check valves used in High Temperature service must be all metal swing type check valves.
3. Dewatering and effluent sump pumps are not designed to handle raw sewage.
4. Maximum intermittent operating temperature for high temperature pumps must not exceed
200 °F (93 °C).
5. 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.
6. Vent hole. 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
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 50 or 90 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 some applications may cause too much turbulence. 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.
7. Pump should be checked frequently for debris and/or build up which may interfere with
the float "on" or "off" position. Repair and service should be performed by Zoeller Pump
Company Authorized Service Station only.
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.
