Failure to follow these instructions could result in pump failure or property d am ag e. Read every supplied manual before using pump system. Follow all the safety instructions in manual(s) and on t he pump. Failure t o do so could result in serious injury or death. Sa f et y Pr eca ut ions RISK OF ELECTRIC SHOCK Always disconnect pump(s) from power source(s) before handling or making any adjustments to either the pump(s), the pump system, or the control panel. Accidental contact with electrically live parts, items, fluid, or water can cause serious injury or death. All installation and maintenance of pumps, controls, protection devices, and general wiring shall be done 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. Do not remove cord and strain relief, and do not connect conduit to pump. 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 prot ect ion or if t he PPE is not wat ertight. Do not lift or carry a pump or a float assembly 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. Some products may have internal capacitors that could cause shock. Avoid contact with plug ends after removing from energy source. Do not use metal or any other electrical conducting material to raise the float or contact anything inside an electrically live sump pit. 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 cat ch on fire. When used, electrical outlets shall be simplex of the appropriate rating. 2 | EN Copyright © Liberty Pumps, Inc. 2023 All rights reserved. 7108000L For cord replacement: power cord must be of the same length and type as originally installed on the Liberty Pumps product. Use of incorrect cord may lead to exceeding the electrical rating of the cord and could result in death, serious injury, or other significant failure. These pumps are not to be installed in locations classified as hazardous in accordance with the National Electric Code® , ANSI/ NFPA 70. 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. Sewage and effluent systems produce and may contain flammable and explosive gases. Prevent introduction of foreign objects into basin as sparks could ignite these gases. Exercise caution using tools and do not use electronic devices or have live, exposed electrical circuits in or around basins, open covers and vents. RISK OF SERIOUS INJURY OR DEATH Do not modify the pump/ pump system in any way. M odifications 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. Vent basin in accordance with local code. Proper venting of sewer and effluent gases alleviates poisonous gas buildup and reduces the risk of explosion and fire from these flammable gases. Wear adequate Personal Protective Equipment when working on pumps or piping that have been exposed to wastewater. Sump and sewage pumps often handle materials that can transmit illness or disease upon contact with skin and other t issues. Energizing the control panel or breaker for the first time is potentially dangerous. Licensed electrical personnel should be present when the panel or breaker is energized for the first time. If faults caused by damage or poor installation practices have not been detected, serious damage, injury or death can result when power is applied. 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. Do not position the pump float directly under the inlet from drain tile or in the direct path of any incoming water. 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. Keep pump upright. 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 introduce any consumer item that is not toilet paper into a non-grinder (dewatering, effluent, sewage) pump/ pump system. This includes, but is not limited to the following: feminine products, wipes, towels, towelettes, dental floss, swabs, pads, etc. Items such as these put the pump under undo strain and can result in pump/ pump system failure. Additionally, it creates conditions for discharge line blockage. Submersible Pump--do not run dry. Do not allow pump to freeze. At no time shall the pump be stored within an incomplete wet pit. The pump shall not be placed into the pit until it can be fully operational. General Information Before installation, read these instructions carefully. Each Liberty Pumps product is individually factory tested to ensure proper performance. Closely following these instructions will eliminate potential operating problems, assuring years of trouble-free service. These pumps are to be used for drain (storm) water. Pumps are certified to CSA® and UL® standards. Provide pump serial number in all correspondence. Pumps must be serviced at a qualified repair facility approved by Liberty Pumps. No repair work should be carried out during the warranty period without prior factory approval. Any unauthorized field repairs void warranty. Contact Liberty Pumps at 1-800-543-2550 to locate the closest authorized service center. This pump has been evaluated for use with water only. 7108000L Copyright © Liberty Pumps, Inc. 2023 All rights reserved. 3 | EN Operating Constraints It is extremely important to verify that the pump has been sized correctly for the intended installation. The operating point of the pump must lie within the acceptable range as outlined by the applicable Liberty Pumps performance chart. Operating the pump outside of the recommended range can invalidate the CSA Certification of the pump and can also cause damage and premature failure. Operating outside of the recommended range can cause the pump to exceed its rated nameplate amp draw, which will void the pump certification. It can also cause motor overheating, cavitation, excessive vibration, clogging, and poor energy efficiency. M odel Specif ica t ions For complete listing of models and their specifications, refer to www.LibertyPumps.com/ About/ Engineering-Specs. Pump nameplate provides a record of specific pump information. I nspect ion a nd St or a ge Initial Inspection The pump should be immediately inspected for damage that may have occurred in shipment. 1. Visually check the pump and any spare parts for damage. 2. Check for damaged electrical wires, especially where they exit the motor housing. Contact Liberty Pumps customer service to report any damage or shortage of parts. Storage Before Use RISK OF ELECTRIC SHOCK 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. At no time shall the pump be stored within an incomplete wet pit. The pump shall not be placed into the pit until it can be fully operational. Do not allow the pump to freeze. Pumps are shipped from the factory ready for installation and use. Hold the pump in storage if the pump station is not complete. If storage is necessary, the pump should remain in its shipping container. It should be stored in a clean, dry temperature-stable environment where the pump and its container are covered to protect it from water, dirt, vibration, etc. The cord ends must be protected against moisture. Uninstalled pumps that are idle for greater than three months should have impellers manually rotated once a month to lubricate the seals. Pum p D esign Liberty Pumps provides an integral anti-airlock hole in the volute housing of submersible pumps. Airlock occurs when air gets trapped in the volute/ impeller area of the pump and cannot escape due to the water column above the check valve on the discharge line. When the basin fills with water and the pump is called to activate, the impeller spins in this pocket of air and cannot prime. An anti-airlock hole allows this trapped air to escape, allowing the pump to prime and start pumping. A small spray of water from this hole is normal while pump is running. Bleeding off the air could take from several seconds to more than a minute once the pump starts. For added protection, consider the addition of a back-up pump, such as Liberty Pumps SJ10 SumpJet as well as alarm ALM -P1 or ALM -2 in applications where loss of pump function could result in property damage. If an alarm is used, it must be connected to a separate electrical circuit. Pum p Syst em Com ponent s Float Switches Automatic Models M odels 243, 233, and 453 come with two cords--one to the float switch and the other to the pump motor. The switch cord has a series (piggyback) plug enabling the pump motor cord to be plugged into the back of it. The purpose of this design is to allow temporary manual operation of the pump. For manual operation, or in the event of switch failure, the pump cord can be separated and plugged into the electrical outlet, directly bypassing the switch. Refer to Piggyback Switch Operation on page 6. Switchless (Manual) Models M anual pumps with no switch may be operated by directly plugging into an approved electrical outlet. To prevent excessive seal wear and overheating, pumps should not be run dry for extended periods of time. A minimum 4-1/ 2" water level is recommended. If manual models are to be used with an optional control device, follow the instructions provided with the control and make power connections per those instructions. Set the turn OFF level at 4-1/ 2" or greater. Vertical Magnetic Float Models Do not remove float rods from VM F models for manual use as switch damage will result. Power and Control Cords RISK OF ELECTRIC SHOCK Do not remove cord and strain relief, and do not connect conduit to pump. Each cord has a green lead. This is the ground wire and must be grounded properly per NEC® and/ or local codes. The power and control cords cannot be spliced, though a junction box may be used. 4 | EN Copyright © Liberty Pumps, Inc. 2023 All rights reserved. 7108000L Prepa ra t ion For ordinary ground water pumping applications, the sump basin diameter should be a minimum of 14" (minimum of 10" for models 247, 237, and 457). A larger diameter pit is preferred as it allows for longer pump cycling and reduced switch cycling. The depth of the pit should be at least 12" above the surface on which the pump is resting. A sump basin cover is required for safety and to prevent foreign objects from entering the basin. Prepare Existing Sump [Basin] RISK OF FIRE Always disconnect pump(s) from power source(s) before handling or making any adjustments to either the pump(s), the pump system, or the control panel. If replacing a previously installed pump, prepare the basin by removing the old pump. Separate the discharge pipe at either the check valve or at the union. If neither a check valve nor a union is part of the existing discharge pipe, cut the pipe with a hacksaw and remove the pump. A check valve and optional union will need to be installed at this cut. Clean any debris from the basin. Inspect all remaining equipment in the basin including piping, valves, and electrical junction boxes (if present) and repair or replace as appropriate. If the basin is not already enclosed on the bottom, provide a hard level bottom of bricks or concrete. Do not place the pump directly on earth, gravel, or debris since this can cause excessive wear of the impeller and possible jamming. "The Brick" (Liberty Pumps #4445000) is a pre-molded stable platform designed to fit the submersible pump. It raises the pump 2-1/ 2" off the bottom of the basin, reducing the potential for jamming from rocks and debris. Contact a local distributor to order. Prepare N ew Sump [Basin] Excavation Excavate the hole as small as possible, with a minimum recommended 8" diametrical clearance around the tank. Never place the basin directly in contact with rocks or other sharp objects. Place only fine, 1/ 8" to 3/ 4" pea gravel or 1/ 8" to 1/ 2" washed, crushed stone as bedding between the basin and the hole walls. Do not use sand or native soil as backfill. Properly compact underneath the basin to provide a solid, level base that can support the weight of the filled basin. Inlet Connection & Initial Backfill Use only fine, 1/ 8" to 3/ 4" pea gravel or 1/ 8" to 1/ 2" washed, crushed stone around the bottom of the basin to hold it in place. Do not use sand or native soil as backfill. M ake the inlet connection as required per basin. Final Backfill Keep large rocks, clods, and foreign objects out of the backfill material. Only fine, 1/ 4" to 3/ 4" pea gravel, or 1/ 8" to 1/ 2" washed, crushed stone is recommended. Do not use sand or native soil as backfill. M ound the backfill slightly and allow for natural settling. Provide access to the basin cover for maintenance and service. Compaction of backfill materials must be adequate to ensure the support of the tank, and to prevent movement or settlement. Ant i - Ai rl ock To speed or assist with air bleed in the event of airlock, the addition of a 1/ 8" hole in the discharge pipe is recommended. This hole should be no more than 1/ 8" diameter and drilled low on the pipe--just above the threaded connection to the pump discharge. Refer to figure. Discharge pipe Drill 1/8" antiairlock hole into DISCHARGE PIPE I nst a lla t ion RISK OF ELECTRIC SHOCK All installation and maintenance of pumps, controls, protection devices, and general wiring shall be done 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 Record information from pump nameplate onto cover of these instructions. Complete a visual inspection before lowering into basin. Place pump in basin being sure any mounting interface (i.e., "The Brick" platform, torque stop) is engaged correctly. M odels with wide-angle float switches must have adequate clearance to side wall of basin with free, unobstructed movement throughout its complete travel and must not contact the pump, piping, or other objects. Discharge M ake all discharge connections. A 1-1/ 2" NPT threaded discharge is provided for connection of the discharge pipe. Do not reduce the discharge size to less than 1-1/ 4", as this will affect pump flow and performance. Schedule 40 PVC pressure pipe is recommended; however, flexible discharge hose kits may be used for temporary installations. Connect pipe or discharge hose to the discharge of the pump. Hand-tighten only as over-tightening can damage the pump discharge. Install a union or other means of separating the discharge pipe just above the floor to facilitate removal of the pump if necessary. A check valve is required to prevent the backflow of liquid after each pumping cycle. A gate valve should follow the check valve to allow periodic cleaning of the check valve or removal of the pump. The remainder of the discharge line should be as short as possible with a minimum number of turns to minimize friction head loss. Do not reduce the discharge to below the pump outlet size. Larger pipe sizes may be required to eliminate friction head loss over long runs. 7108000L Copyright © Liberty Pumps, Inc. 2023 All rights reserved. 5 | EN Vent Vent basin in accordance with applicable plumbing codes. Piggyback Switch Operation IM PORTANT: Verify breaker is turned off before plugging in the sw it ch. Automatic models: Plug the piggyback switch into the receptacle. The receptacle must be wired to an appropriately sized breaker. Plug the pump into the piggyback receptacle. Install the cable clamp (if supplied) for strain relief. M a int ena nce a nd Tr oubleshoot ing RISK OF ELECTRIC SHOCK Accidental contact with electrically live parts, items, fluid, or water can cause serious injury or death. Always disconnect pump(s) from power source(s) before handling or making any adjustments to either the pump(s), the pump system, or the control panel. RISK OF SERIOUS INJURY OR DEATH Wear adequate Personal Protective Equipment when working on pumps or piping that have been exposed to wastewater. Sump and sewage pumps often handle materials that can transmit illness or disease upon contact with skin and other t issu es. NO! Normal Temporary Manual Operation Opera t ion RISK OF SERIOUS INJURY OR DEATH Energizing the control panel or breaker for the first time is potentially dangerous. Licensed electrical personnel should be present when the panel or breaker is energized for the first time. If faults caused by damage or poor installation practices have not been detected, serious damage, injury or death can result when power is applied. Starting System Note: These pumps come equipped with an air bleed hole to help prevent air lock. A small spray of water from this hole is normal while pump is running. 1. Verify all plumbing components are installed correctly and functional. Verify all valves are open and ready for pump use. 2. Double check all wire connections. Re-tighten all factory and field connections. 3. Ensure pump has no obstructions. 4. With all electrical and mechanical connections complete and secure, turn on power to pump. 5. Verify operation of the pump and floats. 6. Run several cycles of water through the system to verify correct control operation for the installation. Be certain to complete adequate testing, especially on systems with multiple pumps or custom control configurations. M a i nt ena nce As the motor is oil-filled, no lubrication or other maintenance is required. In the event the pump becomes clogged, the inlet screen can be removed to gain access to the pump impeller. Once the obstruction is removed, the anti-airlock hole should be cleaned. To keep the pump/ pump system operating smoothly, perform the following routine checks: Monthly 1. Pour enough water into the sump to activate the pump when not normally in use to verify proper function. 2. Pumps that are idle in a wet basin must be removed--do not store pump in wet basin. Quarterly 1. Check pump for corrosion and wear. 2. Check for free and unobstructed float switch operation and float switch condition. The float must be able to move freely through its complete travel without any restrictions. 3. Inspect for proper check valve operation. 4. Check that the pit is free from accumulated debris, rocks or other objects that may potentially jam the pump. Annually 1. Inspect and clean basin. Replace any defective components. Troubleshooting Refer to Table 1 for troubleshooting guidance. No repair work shall be carried out during the warranty period without prior factory approval. To do so may void the warranty. Liberty Pumps, Inc. assumes no responsibility for damage or injury due to disassembly in the field.
