1. General Information

Before installation, read the following instructions carefully. Each Liberty pump is individually factory tested to insure proper performance. Closely following these instructions will eliminate potential operating problems, assuring years of trouble-free service.

 Risk of electric shock. To reduce risk of electric shock, always disconnect pump from power source before handling.  The electrical connections and wiring for a pump installation should only be made by qualified personnel.

 This pump is supplied with a grounding conductor and grounding-type attachment plug. To reduce the risk of electric shock, be

certain that it is connected only to a properly grounded, grounding-type receptacle. For added safety, this receptacle may be protected by a ground fault circuit interrupter (GFCI).

 Do not bypass grounding wires or remove ground prong from attachment plugs.  Do not use an extension cord.  This pump requires separate, properly fused and grounded branch circuit. Make sure the power source is properly sized for the

voltage and amperage requirements of the motor, as noted on the pump nameplate.

 The electrical outlet or panel shall be within the length limitations of the pump power cord, and at least 4 feet above floor level to

minimize possible hazards from flood conditions.

 The installation must be in accordance with the National Electric Code and all applicable local codes and ordinances.  Sump and sewage pumps often handle materials which could cause illness or disease. Wear adequate protective clothing when

working on a used pump or piping.

 NEVER dispose of materials such as paint thinner or other chemicals down drains, as they can chemically attack and damage

pump components, potentially causing product malfunction or failure.

 Do not use these pumps in water over 140 F.  When the risk of property damage from high water levels exists, an independent high water alarm such as Liberty’s ALM-2 and/or

a back up pump system such as Liberty’s SJ10 SumpJet or battery backup FKIT441 should be installed.

2. Precautions/Pre-Installation

3. Installation

1. The SumpBox™ is shipped factory assembled; inspect tank, pump, float(s), and accessories for shipping damage. Contact your

dealer with any problems prior to installation.

2. Read all instructions and familiarize yourself with the unit's operation prior to proceeding with the installation. Read pump specifications to assure pump has adequate head performance prior to installation.

3. Risk of electric shock. Always disconnect the pump from the power source before handling or

making adjustments. The pump power cord is equipped with a grounding conductor and grounding-type 3-

prong plug. To reduce the risk of electric shock, be certain that the SumpBox™ unit is connected only to a properly grounded grounding-type receptacle. This receptacle may be protected by a ground fault circuit interrupter (GFCI). All electrical circuitry should be installed in accordance with the National Electric Code (NEC) and all applicable local codes or ordinances. Never remove the ground pin from the plug. Always wear rubber boots when water is on the floor and you must unplug the pump.

4. Never use an extension cord. The electrical outlet or panel shall be within the length limitations of the

pump power cord, and at least 4 feet above floor level to minimize possible hazards from flood conditions.

5. Check to ensure that your power source is adequate to handle the pump amperage. Pump amperage can be found on the nameplate and/or the product literature. Ensure that the electrical supply circuit is equipped with fuses or breakers of the proper capacity.

6. It is recommended that a separate branch circuit be installed for the pump. Such a branch circuit should be sized in accordance with the NEC.

7. Each electrical outlet should be tested to ensure that a proper ground has been established. A UL listed circuit analyzer will indicate if the power, neutral, and ground wire are properly connected.

8. A qualified licensed electrician should install and test all electrical circuits.

9. All plumbing (waste and vent) should done by a qualified professional and in accordance with applicable codes.

10. Liquid temperature must not exceed 140F (60C).

11. Always disconnect the pump from the power source prior to removing or servicing. Keep clear of suction and discharge openings, and to prevent injury, never insert fingers into pump while it is plugged in.

12. Tools required prior to installation: Teflon pipe tape, a hacksaw (or something similar), and a hammer or small sledge hammer.

Rough-In

IMPORTANT: During the rough-in process the clear disposable protective cover should remain on the system to protect the covers and accessories from dirt, gravel, concrete, and other objects.

A. Excavation: Choose a location in the basement that will allow easy access to the

system. Excavate the hole as small as possible, with a minimum recommended 8" 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.

B. Staking Locators: The SumpBox™ basin has 4 staking features in the anti-

flotation flange that will accept up to 1/2” rebar (see fig. 1). Staking will help support the system during inlet connection and backfill.

C. Inlet Connection and Initial Backfill: Only fine, 1/8" to 3/4" pea gravel or 1/8" to

1/2" washed, crushed stone should be used around the bottom of the basin to hold it in place. Do not use sand or native soil as backfill. Make the inlet connection(s) at any of the three inlet hubs on the basin. Select the inlet hubs you

Fig. 2 Cutting the Inlet Hubs

Fig. 3 Drain Tile Placement

wish to use. Cut 1/4” (but not more than 3/4”) of material from those inlet hubs to assure a good drain tile fit (see fig. 2) . Insert the drain tile into the cut inlet hub. Allow about 1” of spacing between the end of the drain tile and the internal strainer basket for good operation and easy removal of the strainer during maintenance (see fig. 3).

D. Final Backfill. Large rocks, clods, and foreign objects should be kept 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. Provide access to the basin cover for maintenance and service.

IMPORTANT: Do not exert heavy pressure or run heavy equipment on the backfill as this could cause damage to the tank.

Finish Plumbing and Alarm Installation

IMPORTANT: All plumbing installations (waste and vent) should done by a qualified professional and in accordance with applicable codes.

A. Remove and recycle the disposable protective cover before plumbing the system.

B. NOTE: Threaded connections at cover - HAND TIGHTEN ONLY and use Teflon tape as a thread sealant. Remove the gray

plug and install 1-1/2” PVC pipe to the cover connection labeled “1-1/2” DISCHARGE” (see figure 4). A union should be installed to facilitate pump removal if necessary. A free-flow swing check valve is recommended after the union to prevent the backflow of liquid after each pumping cycle. A gate or ball 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. Contact Liberty Pumps or other qualified person if you have questions regarding proper pipe sizes and flow rates.

C. If your system is equipped with an alarm, refer to the alarm Installation Instructions for proper connection. The alarm box and

accessories are located under the clear protective cover. The alarm switch cord has bare wire leads and exits the cover through the single hole grommet (see fig. 4).

4. Operation and Maintenance

A. For automatic operation, the two cords should be

interconnected and plugged (see fig. 6) into a separately fused, grounded outlet of proper amp capacity for your selected pump model (see Section 1, General Information, or the pump nameplate for electrical specifications of your model.) Both cords are equipped with 3-prong plugs and must be plugged into a properly grounded 3-wire receptacle.

DO NOT REMOVE GROUND PRONGS FROM ATTACHMENT PLUGS.

B. Pump and alarm switch levels are preset at the factory. If

for any reason the switch levels change, please refer to fig. 7 for proper re-adjustment of the switch. It is recommended that the system be disconnected from the power source and the switch be removed to perform this operation. Periodically check the condition of the switches to ensure proper operation by removing debris or build up that would render the switch inoperable.

C. To clean the strainer basket, loosen the two wing bolts and

remove the access cover. Lift up on the two handles (see fig.8) and remove the strainer basket. Caution: water will continue to drip from strainer after removal. Clean the basket by dumping the debris and rinsing. Reinstall the strainer basket as soon as possible to prevent debris from entering the tank. Reinstall the access cover. It is strongly recommended that this be done frequently during new home construction and every 6 months thereafter or as needed.

D. To remove a switch, open the access cover and remove the

strainer basket. Remove the appropriate cord grommet on the secure cover and pull the switch cord through the open hole. Remove switch bracket using a 7/16” socket or nut driver (see Figure 10). The switch can now be lifted from its pocket and be serviced or replaced. To reinstall a switch, place it back into the float pocket. Route the switch cord around the internal inlet hub (see fig. 9). The switch cord should not interfere with filter tray operation. Pull the end of the switch cord through the grommet hole in the cover and reinstall the cord grommet.

E. To reinstall a switch, place it back into the float pocket. Route

the switch cord around the internal inlet hub (see Figure 9). The switch cord should not interfere with filter tray operation. Secure switch with switch bracket using a 7/16” socket or nut driver (see Figure 10). Pull the end of the switch cord through the grommet hole in the cover and reinstall the cord grommet.
