INSTALLATION INSTRUCTIONS
SEE BELOW FOR
LIST OF WARNINGS
1. Make certain that the receptacle is within reach of the pump’s power supply
cord. Do not use primary pump circuit. 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.
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 pools and marine areas.
11. Prop65 Warning for California residents: Cancer and Reproductive Harm-
www.P65Warnings.ca.gov.
12. It is the owner’s responsibility to check the battery and battery connection at
least once a month. Batteries contain acid and caution must be taken when
handling.
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. 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. Vent holes should
be checked periodically for clogging. The 50 Series pumps have a vent
located in the pump housing opposite the float, adjacent to a housing lug.
Water stream will be visible from this hole during pump run periods.
3. 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 an Authorized Service and Warranty Center only.
4. Dewatering and effluent sump pumps are not designed for use in pits
handling raw sewage.
5. Maximum operating temperature must not exceed 130 °F (54 °C).
6. 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.
7. For indoor use only.
8. DC emergency pumps are designed for handling clear water. Do not use
in septic tanks to pump effluent or sewage pits to pump sewage.
9. Repair and service of your DC backup system should be performed by
an Authorized Service and Warranty Center.
10. The installation of DC automatic backup pumps requires the use of a variable
level float switch for operation. It is the responsibility of the installing party,
to ensure that the float switch will not hang up on the pump apparatus or
pit peculiarities
and is secured so the pump will turn “on” and “off”. It is
recommended that the pit be 18" (45.7 cm) in diameter or larger to accom-
modate both a primary and a DC backup pump.
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.
