LIST OF WARNINGS
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. 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" or larger in diameter.
6. 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 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. 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.
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.
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.
(SEE WARNING BELOW)
2. 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. But, more important, they could present a safety hazard if the
insulation were to become damaged or the connection end were to fall into the sump.
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
FM0514 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.
11. According to the state of California (Prop 65), this product contains chemicals known to the state
of California to cause cancer and birth defects or other reproductive harm.
