Important Safeguards
To reduce risk of injury, always follow these instructions and safety precautions when
using this pump and to maintain warranty.
Read All Instructions Prior to Installation
(SAVE THESE INSTRUCTIONS)
Installation/Operation
• Never lift or carry the pump by the electrical cord. Use a chain or rope affixed to the
handle to install or remove the pump. To reduce potential damage to the pump from
inadvertent lifting by the electrical cord, refer to “Proper Lifting” on page 2
• This pump must be operated fully submerged. Pump must be shutdown if the sump,
pit, or pond level drops below the motor housing.
• Pump is designed to pump clean water (maximum temperature of 122
suspended solids up to 3/16 of an inch. Larger solids will clog the suction strainer plate
leading to dry running and subsequent failure. (Note: Pumping sand, gravel, and other hard debris will shorten the life of the pump.) Elevate the pump with bricks or other
support above the sump, pit or pond bottom if debris is present.
• Clean the filter basin when cleaning the inlet filter media when the pump is shut down.
• If used with a float switch, the float must have a full range of motion to operate properly
without obstruction. Refer to “Submersible Pump Installation” on page 9
• Pump should be mounted upright only (vertical). Never lay the pump on its side.
Electrical Requirements
• Pump must be operated with a GFCI breaker of at least 15 amps.
• High OR Low Voltage can damage the pump. Power from your utility or generator set
cannot be more or less than 10% of the rated voltage shown on the pump.
• Maximum distance from power source and pump must not exceed 100 feet using 16/3
electrical cables. This distance is from the breaker box and includes the pump cord. If
the run is longer, consult a qualified electrician or your dealer.
• Lightning strikes can destroy the capacitor in your pump. Ensure proper protection is
provided.
• Consult this manual for additional operation and application information.

Proper Lifting
A separate chain or rope should be attached to the handle for normal lifting.
Note that this will help prevent damage due to inadvertent lifting of the pump by the
power cord.

General Application Information
The Sump and Installation
If your basement does not currently have a sump installed, it will be necessary to check
local plumbing codes as to the acceptable type of sump that may be used. Materials
commonly specified are: clay tile, fiberglass, steel, concrete, and polyethylene. It may be
necessary to cut a hole in the basement floor and excavate for the sump. Plumbing and
electrical contractors can advise on proper installation of drain tiles, sump, pump, and
electrical service. Honda recommends that a solid sump base be provided. The sump is
fed by drain tile placed around the outside and/or inside basement walls at the footings. In
applications where a gravel base must be used to relieve hydraulic pressure under the
basement floor, be sure to provide a permanent and solid base for the pump (bricks or a
steel plate). A sump cover capable of supporting 200 pounds should be employed to
contain odors and for obvious safety reasons.

Electrical Installation
Electrical service for any sump pump installation must be grounded and separately fused
or breakered directly from the entrance box with a single grounding type receptacle at the
pump. The receptacle should not be less than four feet above the basement floor for
safety reasons. Y ou should never touch a sump pump or discharge piping while the pump
is connected to electrical power and water is present. The pump should be disconnected
from the electrical source before handling in all cases.
Discharge Piping Installation
To assure the maximum performance from your sump pump, the discharge pipe size and
piping fittings should not be smaller than the discharge port of the pump. Smaller pipe will
add to friction losses and reduce the capacity of the pump. Normally accepted materials
are galvanized pipe, rigid plastic pipe, or acceptable flexible pipe or hose. A piece of
flexible hose between the pump discharge and the discharge piping will provide for ease
in alignment, reduce vibration and noise, and will act as a union when it is necessary to
remove the pump. Where the discharge pipe is long, a check valve is often employed to
prevent the water from flowing back into the sump when the pump turns off. If the
discharge is directed into a sanitary sewer, a suitable anti-siphon device or a free flow
check valve should be inserted in the line to prevent backflow into the pit. Sump pumps
are not designed to handle raw sewage (see “Septic Tank Installation” on page 7
attempt to adapt one for this type of application. A sewage ejector pump especially
designed to handle solids must be used.
Pump Installation
When the sump, electrical and discharge plumbing installation is complete and ready for
the pump, clean all solid debris from the pit. Complete the plumbing connection to the
pump and then plug the pump into the electrical outlet. A few extra minutes to test the
sump pump installation are now in order. Fill the sump with water, note the turn on and
turn off level of the pump, and the pumping cycle. This will allow you to calculate the
approximate discharge flow of the pump system. If everything is operating properly, install
the sump cover.
Pump Selection
). Do not
The pump should be of sufficient capacity and head to satisfy anticipated use
requirements.
Basement perimeter water intrusion varies by area and region. Typically a 1/3 HP or 1/2
HP DRAINAGE PUMP WILL EVACUATE MOST HOME SUMP PITS. Commercial and
industrial drainage applications require that calculations of pumping volume and pumping
head be performed to determine the proper size pump is applied.
NOTE: Pumping volume may vary seasonally due to rainfall and area run-off.

Basin and Cover
The basin should not be less than 18 inches in diameter and 24 inches deep. Larger
diameters are advisable in instances of increased pump capacity requirements:
Required Pump CapacityMinimum Basin Diameter
Up to 35 GPM18"
Over 35 GPM24"
Over 60 GPM30"
Over 100 GPM36"
Over 150 GPM48"
The basin should be located such that all water flows into the basin due to gravity.
Outdoor installations should be at a sufficient depth to ensure protection from freezing.
Maintenance Tips
• Every three or four months:
1) Clean the pump screen or inlet opening. If your sump collects the discharge from an
automatic washing machine, cleaning will be required more often. (Before removing
the pump, be sure to disconnect the unit from electrical power; and reconnect after
completion of cleaning).
2) Pour enough water into the sump to cycle the pump and assure its proper
functioning.
• Annually:
Remove and clean the pump. Clean the sump pit also.
