PREINSTALLATION CHECKLIST – ALL INSTALLATIONS

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.
Carefully read the literature provided to familiarize yourself with specific details regarding installation and use. These materials should beretained for future reference.

WARNING
SEE BELOW FOR LIST OF 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. 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.
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.
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.
“Risk of electrical 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.
Prop65 Warning for California residents: Cancer and Reproductive Harm- www.P65warnings.ca.gov.

CAUTION
SEE BELOW FOR LIST OF CAUTIONS

Check to be sure your power source is capable of handling the voltage requirements of the motor, as indicated on the pump name plate.
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.
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.
Maximum operating temperature for standard model pumps must not exceed 130°F (54°C).
Pump models 266, 267, 268, and 137 must be operated in an upright position. Do not attempt to start pump when tilted or laying on its side.
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.

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.
