Safety Precautions

RISK OF ELECTRIC SHOCK

Accidental contact with electrically live parts, items, fluid, or water can cause serious injury or death.
Always disconnect the pump from power source before attempting to service the pump. Fatal electrical shock could occur.
All installation and maintenance of pumps, controls, protection devices, and general wiring shall be done by qualified personnel.
The pump shall be plugged into a properly fused electrical outlet with a ground fault circuit interrupter (GFCI) that conforms to current National Electric Code (NEC) and all applicable local codes. All wiring must be performed by qualified personnel.
All electrical and safety practices shall be in accordance with the National Electrical Code®, the Occupational Safety and Health Administration, or applicable local codes and ordinances.
Pump shall be properly grounded using its supplied grounding conductor. Do not bypass grounding wires or remove ground prong from attachment plugs. Failure to properly ground the pump system can cause all metal portions of the pump and its surroundings to become energized.
Do not handle or unplug the pump with wet hands, when standing on damp surface, or in water unless wearing Personal Protective Equipment.
Always wear dielectric rubber boots and other applicable Personal Protective Equipment (PPE) when water is on the floor and an energized pump system must be serviced, as submerged electrical connections can energize the water. Do not enter the water if the water level is higher than the PPE protection or if the PPE is not watertight.
Do not lift or carry the pump by its power cord. This will damage the power cord, and could expose the electrically live wires inside the power cord.
The electrical power supply shall be located within the length limitations of the pump power cord, and for below grade installations it shall be at least 4 ft (1.22 m) above floor level.
Do not use this product in applications where human contact with the pumped fluid is common (such as swimming pools, fountains, marine areas, etc.).
Protect the power and control cords from the environment. Unprotected power and control (switch) cords can allow water to wick through ends into pump or switch housings, causing surroundings to become energized.

RISK OF FIRE

Do not use an extension cord to power the product. Extension cords can overload both the product and extension cord supply wires. Overloaded wires will get very hot and can catch on fire.
This product requires a separate, properly fused and grounded branch circuit, sized for the voltage and amperage requirements of the pump, as noted on the nameplate. Overloaded branch circuit wires will get very hot and can catch on fire. When used, electrical outlets shall be simplex of the appropriate rating.
Do not use this product with or near flammable or explosive fluids such as gasoline, fuel oil, kerosene, etc. If rotating elements inside pump strike any foreign object, sparks may occur. Sparks could ignite flammable liquids.
These pumps are not to be installed in locations classified as hazardous in accordance with the National Electric Code®, ANSI/NFPA 70.

RISK OF SERIOUS INJURY OR DEATH

Do not modify the pump/pump system in any way. Modifications may affect seals, change the electrical loading of the pump, or damage the pump and its components.
All pump/pump system installations shall be in compliance with all applicable Federal, State, and Local codes and ordinances.
Do not allow children to play with the pump system.
Do not allow any person who is unqualified to have contact with this pump system. Any person who is unaware of the dangers of this pump system, or has not read this manual, can easily be injured by the pump system.
Do not remove any tags or labels from the pump or its cord.
Keep clear of suction and discharge openings. To prevent injury, never insert fingers into pump while it is connected to a power source.
Do not use this product with flammable, explosive, or corrosive fluids. Do not use in a flammable and/or explosive atmosphere as serious injury or death could result.
This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. www.p65warnings.ca.gov.
This pump has been evaluated for use with water only.
Do not use pumps with fluid over 140°F (60°C). Operating the pump in fluid above this temperature can overheat the pump, resulting in pump failure.
Do not dispose of materials such as paint thinner or other chemicals down drains. Doing so could chemically attack and damage pump system components and cause product malfunction or failure.
Do not use pump system with mud, sand, cement, hydrocarbons, grease, or chemicals. Pump and system components can be damaged from these items causing product malfunction or failure. Additionally, flooding can occur if these items jam the impeller or piping.
Do not run dry.
Do not use an air admittance valve or a mechanical spring-loaded venting device, as these devices are one-way valves. The air pressure in and outside the pump unit must be equal and a “cheater” vent will obstruct the airflow in one direction and prevent proper function.
Use of a lint trap on a washing machine drain is recommended for proper check valve performance.

Typical Installations

Preparation

Before installing the Model 406 automatic drain pump, take the following into consideration:

Layout

The layout should be considered prior to installation. The power source (GFCI receptacle) shall be within range of the unit’s 9’ power cord. The GFCI receptacle shall be a minimum of 40” away (in a straight line) from a shower or bathtub. For basement installation, the receptacle shall be 48” from the floor.

Power Cord

The power cord can be configured to exit the unit on either the left or right side, with any extra cord coiled and tucked away under the decorative cover.

Easy Access

The unit should be accessible in the event of required maintenance. During installation, a full port ball valve should be installed at the base of the discharge to allow easy service of the unit.

Pipework

All pipework shall be copper, PVC, or CPVC. Do not use flexible or semi- flexible pipe. All sanitary pipework shall be supported in accordance with the pipe manufacturer’s recommendations.

Discharge

Never discharge directly into an open drain, fixture, manhole or rainwater drainpipe. It is illegal as it constitutes a health hazard. Only direct connections into sanitary waste systems shall be acceptable.

Bathtub/Shower

If a bathtub or shower is connected, a base will have to be constructed. This base should be made out of a 2” x 6” (minimum) or 2” x 8” (recommended) on edge to allow for the installation of a P-trap and the required 1/4” per foot gravity flow toward the unit. Allowing at least 6–8” fall ensures proper drainage and prevents any backflow.

Vertical Lift

If vertical lift is required, this shall precede the horizontal pipe run. Once the horizontal run is started, do not change directions in a vertical manner.

Bends

Only long sweeping bends shall be used. Do not use short elbows (90° elbows). If sweeping 90° elbows are not available, use two 45° elbows to make a 90° turn.

Inlet

All inlet pipework shall have a positive gravity fall of at least 1/4” per foot.

Discharge Piping

All discharge piping from the unit shall run either directly vertical or in a horizontal plane (with a minimum 1/4” per foot drop) to the point of discharge. Pipework shall not be installed with a diagonal upward slope from the unit to the point of discharge. Long downward pitched runs of discharge piping, or piping where the point of discharge is at a lower elevation than the unit, shall be designed to prevent siphoning from the tank.

Trap

A trap shall be used between the fixture and pump; a flange type is recommended.

Freezing

Ensure all pipework susceptible to freezing is adequately insulated or heated. In unheated buildings, the unit and piping shall be properly winterized. Use plumbing antifreeze or drain completely.

Installation

All cut pipe ends must be clean and deburred to ensure a good connection.

Top Inlet

Either side top port (center is discharge) can be used as an inlet. Connect the fixture (i.e., laundry tub, bar sink, washing machine (indirectly via laundry tub)) to the unit using a flexible coupling/clamp.

Note: Use of a lint trap on a washing machine drain is recommended for proper check valve performance.

If the top inlet is not being used, secure the plug to the inlet.

Side Inlet

The pump has two side inlets on either side to accommodate sanitary fixtures. To connect to the side inlets, use provided rubber coupling/clamps. Only one check valve is included for the side inlet coupling. If both inlets are being used, another check valve is required.

Note: The side inlet check valve does not seat flush into the connector. The check valve is tipped; this is the correct installation orientation.

If either side inlet is not being used, secure the plug to the inlet.

Vent

Do not use an air admittance valve or a mechanical spring-loaded venting device.

Either side top port (center is discharge) can be used as a vent. Use a flexible coupling/ clamp to connect the vent to the PVC pipe for the vent connection.

The vent pipe should have a union to facilitate removal and shall be connected directly to a building or house vent.

Discharge

The wastewater being evacuated from this unit shall be discharged using a 1”, 1.25” or 1.5” diameter copper or plastic (PVC, CPVC) pipe. This pump is designed to handle 1/8” particles. The discharge pipe shall be connected to a drain line or sewer line using an approved “Y” fitting designed for this purpose.

Install a union just above the unit to facilitate removal when needed for cleaning or service.

Test System

Plug the cord into a properly grounded GFCI receptacle.
Allow water to fill the basin.
Check all plumbing for leaks as the basin fills.
Verify that the pump starts and stops.
Check the discharge line for leaks as the pump empties the basin.
Repeat Steps 2 through 5 as necessary to ensure proper operation.
If problems persist, refer to Troubleshooting.

Operation

Unit will turn on when the liquid level has risen to activate the float switch. No user interaction is required. Likewise, the unit will turn off when the liquid is removed to such a level as the pump is no longer required.

Maintenance and Troubleshooting

RISK OF ELECTRIC SHOCK

Always disconnect the pump from power source before attempting to service the pump. Fatal electrical shock could occur.

Maintenance

If used infrequently, test the unit monthly to verify proper operation.

Routine maintenance is not required on the pump itself, but associated connections may require occasional attention.

Lint and foreign objects should be removed from the trap periodically. The check valve on the discharge should also be checked for freedom of operation at the same time.

Foam gaskets under top plug(s) may wear/tear and need replacement. Two gaskets are included in the connection kit. Replace as needed.

Replacement connection kit #K001929 is available from Liberty Pumps.

Troubleshooting

In the event service needs to be done on the unit, the pump and float switch are easily accessible under the decorative cover.

For wet end serviceability, remove the pump cartridge by a 1/4 turn. The pump cartridge is clearly marked with LOCK and UNLOCK arrows.

Note: the pump cartridge turns clockwise to unlock. This is so that when the pump turns on, the kick direction has a positive stop and won’t loosen the cartridge over time.

The float switch is accessed for cleaning and/or replacement by removing four screws.
