S2n1 PREASSEMBLED SUMP PUMP SYSTEM

WITH BATTERY BACKUP

12V DC BATTERY BACKUP SYSTEM WITH 120V AC POWERED SUMP PUMP MODEL 3SDHL

PRE-INSTALLATION CHECKLIST

1. Inspect your pump. Occasionally, products are damaged during shipment. If the unit or any of the parts are
damaged, contact your dealer before using.

2. Read all the installation instructions regarding installing and start up. Retain for future reference.

1. WARNING: 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.

WARNING: 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.

WARNING: 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.

WARNING: 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.

WARNING: 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. 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.

WARNING: “Risk of electrical shock” Do not
remove power supply cord and strain relief or connect
conduit directly to the pump.

WARNING: Installation and servicing of
electrical circuits and hardware should be performed
by a qualified licensed electrician.

WARNING: Pump installation and servicing
should be performed by a qualified person.

WARNING: Risk of electric shock - These
pumps have not been investigated for use in
swimming pool and marine areas.

WARNING: 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.

11. CAUTION: Check to be sure your power source
is capable of handling the voltage requirements of the
motor, as indicated on the pump name plate.

12.

CAUTION: 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.

13.

CAUTION: Information - vent hole purpose.
It is necessary that all submersible sump pumps
capable of handling various sizes of solid waste be of
the bottom intake design to reduce clogging and seal
failures. A check valve with an integral weep hole
is incorporated in the installation to purge the unit of
trapped air (See Page 4). Trapped air is caused by
agitation and/or a dry basin. Vent hole should be
checked periodically for clogging. NOTE: THE HOLE
MUST BE CLEANED PERIODICALLY. Water stream
will be visible from this hole during pump run periods.

14.

CAUTION: 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 Star Water Systems Authorized
Service Station only.

15.

CAUTION: Sump pumps are not designed for
use in pits handling raw sewage.

16.

CAUTION: Maximum operating temperature
for standard model pumps must not exceed 104°F
(40°C).

Note: Pumps with the "cCSAus" mark are tested to UL
Standard UL778 & CSA Standard C22.2 No. 108.

GENERAL INFORMATION

The 2N1 system is designed to provide a primary and a
backup sump pumping capabilities. The primary pump
will operate as long as it is receiving AC electrical power.
The AC power is interrupted, the backup sump pump
will begin pumping automatically. The primary pump,
backup pump, electronic controls and all parts required
for installation are included except the battery which is
supplied by the user.

1. The primary pump is equipped with an
omnidirectional mechanical float switch. The pump
will turn on automatically when the water level
in the sump reaches approximately 10.25” and
automatically turn off when the water is pumped
down to 4.125”. The back-up pump is equipped
with a vertical float switch. The pump will turn on
automatically when the water level in the sump
reaches approximately 11” and automatically turn off
when the water is pumped down to 9.25”.

2. The sump pit must be a minimum of 22" deep and
18" in diameter. The pump assembly requires a
minimum diameter of 18" so that the float switches
will operate without restriction. Any smaller diameter
may restrict the switches operation, resulting in pump
failure.

INSTALLATION

1. For your safety, turn off the electrical power at the
service entrance to avoid any possible electrical
shock hazards.

2. On a replacement installation, remove the existing
pump from the sump by disconnecting the discharge
pipe or hose from the old pump. Depending on how
your old pump is installed, unscrew clamps and
discard old corrugated hose, or unscrew galvanized
or plastic pipe from pump discharge. If discharge
pipe cannot be removed easily, saw through the pipe
about five feet above the pump discharge.

3. After removing the old pump, remove sediment,
debris, and any standing water from the sump pit.

4. Place your pump assembly in the sump and attach
the discharge piping – The pipe must be supported
from above to ensure adequate support for the pump
assembly.

5. Be sure that the pump assembly is positioned so that
the float switches move freely without touching the
wall of the sump or other obstructions. (See Fig. 1)
Ensure that the “off” level of the float is 1" min. above
the discharge tee of the DC backup pump (see Fig.

1). Move floats up and down, making sure of free
movement without interference from any obstructions
inside the sump or lid. Very shallow sumps may
require some adjustment to the vertical float to avoid
overfilling or backing up of water into the sump inlet.
