General Safety Information
Safety is a combination of common sense, staying alert
and understanding how your sump pump works.
Safety Signal Words
means if the safety information is not
followed someone will be seriously injured or killed.
means if safety information is not fol-
lowed someone could be seriously injured or killed.
means if safety information is not fol-
lowed someone may be injured.
indicates important information, that if
not followed, may cause damage to the equipment or
flooding.
Read and understand all instructions. Failure to follow all instructions listed below
may result in fatal electric shock, fire, property
damage, and/or serious personal injury.
SAVE THESE INSTRUCTIONS!
Work Area
• Do not operate pump in explosive atmospheres,
such as in the presence of flammable liquids,
gases, or dust. Pump motors create sparks
which may ignite the dust or fumes.
• Keep by-standers, children, and visitors away
while installing pump. Distractions can result in
mistakes.
Electrical Safety
• This pump must be plugged into an outlet,
properly installed, and grounded in accordance
with all applicable codes and ordinances. Never
remove the grounding prong or modify the plug
in any way. Do not use any adapter plugs. Check
with a qualified electrician if you are not sure the
outlet is grounded. If the pump should electrically
malfunction or break down, grounding provides a
low resistance path to carry electricity away from the
user.
• Electrical wiring must be performed by a quali-
fied electrician. Improper wiring could result in fatal
electrical shock.
• Do not abuse cord. Never use the cord to carry
the pump or pull the plug from an outlet. Keep
cord away from heat, oil, sharp edges, or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electrical
shock.
• Pump must be plugged into an outlet recepta-
cle that includes a Ground Fault Circuit
Interrupter (GFCI). In the event of current leak-
age, a GFCI will trip, thus reducing the risk of serious injury or death from electrical shock.
Figure 1
• Before using, test the Ground Fault Circuit
Interrupter (GFCI) to insure it is operating correctly. A GFCI reduces the risk of electrical shock.
• Do not use an extension cord. This increases
the risk of electrical shock. If necessary, install a
properly grounded outlet closer to the pump.
Personal Safety
• Stay alert, watch what you are doing, and use
common sense when installing this pump. Do
not attempt to install this pump while tired or
under the influence of drugs, alcohol or medications. A moment of inattention may result in
serious personal injury.
• Dress properly. Do not wear loose clothing or
jewelry. Contain long hair. Keep your hair,
clothing, and gloves away from moving parts.
Loose clothes, jewelry, or long hair can be caught
in moving parts.
• Do not overreach. Keep proper footing and bal-
ance at all times. Proper footing and balance
enables better control in unexpected situations.
• Use safety equipment. Always wear eye protec-
tion. Dust mask, non-skid safety shoes and hard
hat must be used for appropriate conditions.

Service
• The motor is oil filled and sealed for cooler running. Allow 2 hours for the motor to cool before
servicing. Hot oil is under pressure and could
result in severe burns.
• Pump service must be performed only by qual-
ified repair personnel. Service or maintenance
performed by unqualified repair personnel could
result in injury and may void the warranty.
• When servicing a pump, use only identical
replacement parts. Follow instructions in the
Maintenance Section of this manual. Use of
unauthorized parts or failure to follow maintenance
instructions may create a risk of electrical shock or
injury.

Submersible Pump Safety
• Do not use to pump flammable or explosive fluids such as gasoline, fuel oil, kerosene, solvents, thinners etc. Do not use in a flammable
and/or explosive atmosphere. Pump should
only be used to pump clear water. Improper use
could result in personal injury and/or death.
• If there is water or moisture on the floor or
ground near the pump, do not walk on wet area
until all power is turned off. If the shut-off box
is in the basement, call an electrician.
Failure to
follow this warning could result in fatal electrical
shock.
• Always disconnect the power source before
attempting to install, service, relocate, or maintain the pump. Never handle a pump or pump
motor with wet hands or when standing on wet
or damp surface or in water. Failure to follow this
warning could result in personal injury and/or
death.
• Pump motor is equipped with automatic reset-
ting thermal protector that could restart unexpectedly. Disconnect power source when servic-
ing pump.
• Do not modify float or position float switch so
that pump will operate continuously. Pump is
not designed for continuous operation, this will
reduce performance and life of the pump.
• Do not hang pump by handle for permanent
installation. This minimizes twisting which can
lead to damage during pump operations.
Description and Specifications
Description
The submersible pump is designed for home sump
operations only. The unit is equipped with an 8 foot, 3prong grounding type power cord. The motor has an
automatic reset thermal protector to prevent burnouts
due to overloading or clogging. A float activated switch
provides automatic operation to maintain water level
between factory preset points.
This pump is not designed to handle
salt water, brine, laundry discharge, or any other application which may contain caustic chemicals and/or foreign materials. This pump is not suitable for use with
aquatic life. Pump damage or failure could occur if
used in these applications and will void the warranty.
It is strongly recommended that a
battery back-up system be used. Power outages,
excessive water flow, G.F.C.I. tripping and primary
pump wear can cause flooding. A battery back-up system reduces this risk. Contact your Ridge Tool distributor.

Pump Installation
• Pump should only be used to pump clear
water. Do not use to pump fluids such as gasoline, fuel oil, or kerosene. Do not use in a flammable or explosive atmosphere. Improper use
could result in personal injury and/or death.
To prevent property damage,
serious injury, or death, proper installation of the
pump is required. The following procedures
should be followed:
• Pump must be plugged into an outlet receptacle that includes a Ground Fault Circuit
Interrupter (GFCI)
(Figure 1)
.
• Always disconnect the power source before
attempting to install, service, relocate, or maintain the pump. Never handle a pump or pump
motor with wet hands or when standing on wet
or damp surface or in water.
Installation
1. Construct a sump pit from concrete, steel, or plastic that is 24” deep and at least 11” in diameter
(Figure 2 next page)
. If the sump already exists,
make sure it is the proper size.
2. Make sure the electrical outlet is grounded and is
rated for 115 volts and at least 15 amps. The outlet must be protected by a Ground Fault Circuit
Interrupter (GFCI).
Use of a grounded receptacle that
is protected by a GFCI reduces risk of a fatal electrical
shock.
3. Inspect the power cord and plug for damage. If the
plug is missing the grounding prong or the cord is
damaged, do not install the pump until the cord has
been replaced.
(Model SP-330D Diaphragm Switch only)
4. Remove the two fasteners in the cast iron volute
near the discharge area. Align the hole with the
diaphragm switch and replace the fasteners without over tightening.

Never cut off grounding prong or
use an adapter.
Support pump and piping when
assembling and after installation. Failure to do so
could cause piping to break or pump to fail, which
could result in property damage and/or personal injury.
5. Set pump into sump. Locate the pump on a solid
level surface.
Do not place directly on clay, gravel,
or any loose or sandy surfaces. These surfaces contain small stones or sand that may clog or damage the
pump, which could result in pump failure causing
flooding and property damage.
6. This pump has a 1-1/2” NPT discharge. If existing
piping is 1-1/4” NPT, an adapter bushing (not
included) may be used. Do not use piping that is
less than 1-1/4” NPT. Piping that is too small will
result in reduced output.
7. A check valve is required in the discharge line to
prevent backflow when the pump shuts off. It is
best to install the check-valve directly to the pump
discharge. Thread a check valve into pump discharge.
Be careful not to strip or cross-
thread. Do not use pipe joint sealant.
Flexible discharge hose is intended
for temporary use only. Rigid PVC or metal pipe is
required for a permanent installation. If flexible discharge hose is temporarily used, make sure pump is
secured in sump pit to prevent movement. Failure to
secure pump could allow pump movement and cause
switch interference and prevent pump from starting or
stopping. This could result in flooding and property
damage.
IMPORTANT! Make sure there is adequate room for
float switch to move freely during operation. A 1”
minimum is required.
8. Connect 1-1/4” diameter rigid pipe to rubber boot
on check valve (not included). Reverse boot for 11/2” diameter pipe. Tighten clamps.
9. Insert the pump cord plug directly into 115 volt
grounded electrical outlet that is protected by
Ground Fault Circuit Interrupter (GFCI)
(Figure 1)
.
When routing electrical cord protect
cord from sharp objects, hot surfaces, oils, and chemicals. Do not kink cord, replace any damaged cord
immediately.
Flood Alarm Models (see figure 3)
Figure 3- Water Sensor
Figure 4 – Alarm models
Unit should be plugged into outlet as shown in figure 4.
Do not plug alarm box in upside down. Doing so may
cause the pump to unplug. If the outlet is upside down,
have a qualified electrician reposition the outlet before
installing the unit.
Testing
1. Fill sump pit with water.
2. While the pump is draining the pit, verify that the
discharge piping is carrying the water to a point at
least 15 feet away from the foundation.
