ZOELLER 63, 95 Sump Pump

Inspect all materials. Occasionally, products are damaged during shipment. If the unit is damaged, contact your dealer before using.
DO NOT remove the test/oil fill plugs from the pump.
Carefully read the literature provided to familiarize yourself with specific details regarding installation and use. These materials should be retained for future reference.

WARNINGS

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 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.
Check to be sure your power source is capable of handling the voltage requirements of the motor, as indicated on the pump name plate.
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.
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.
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.
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.
Risk of electric shock. Do not remove power supply cord and strain relief or connect conduit directly to the pump.
Installation and servicing of electrical circuits and hardware should be performed by a qualified licensed electrician.
Pump installation and servicing should be performed by a qualified person.
Risk of electric shock. These pumps have not been investigated for use in swimming pool and marine areas.

CAUTION

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 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 pump has a vent hole located in the pump housing opposite the float, adjacent to a housing lug, but an additional vent hole is recommended. 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.
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.
Dewatering and effluent sump pumps are not designed for use in pits handling raw sewage.
Non-automatic pumps with external-level controls are recommended for septic tank effluent applications.
Maximum operating temperature for standard model pumps must not exceed 130 °F (54 °C).
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 Curve.
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.
