The grinder pump and the control panel are supplied with their own separate Installation/Operation/Maintenance

manuals. Ensure that you have received these manuals, and that you read and understand them prior to installing this unit. Your

familiarity with the grinder pump manual and the control panel manual is critical. This installation manual gives a brief overview of the

system, and deals mainly with inspection and installation of the basin, but it does not cover the specifics of the pump operation or the

control panel operation. If you have any questions, call customer service at (800) 543-2550.

2 Precautions / Pre-Installation

 Risk of electric shock. Always disconnect the pump from the power source before handling or making adjustments.

 These pumps are not to be installed in locations classified as hazardous in accordance with the National Electric Code, ANSI/NFPA

70.

 The electrical connections and wiring for a pump installation should only be made by qualified personnel.

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

certain that the grounding conductor is connected only to a properly grounded control panel or, if equipped with a grounding-type

plug, that it is connected to a properly grounded, grounding-type receptacle.

 Do not bypass grounding wires or remove ground prong from attachment plugs.

 Do not remove cord and strain relief, and do not connect conduit to pump.

 Do not use an extension cord.

 This system requires separate, properly fused and grounded branch circuit. Make sure the power source is properly sized for the

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

 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 enter a pump basin after it has been used. Sewage and effluent can emit several gases which are poisonous.

Pre-installation checklist:

1. Inspect the unit upon arrival to ensure that there is

no shipping damage. Pay careful attention to the

condition of the fiberglass basin, control floats,

pump guide rail brackets, and control panel. Notify

the carrier immediately if there is any damage.

2. Read all instructions and familiarize yourself with

the unit’s operation prior to proceeding with the

installation.

3. A qualified licensed electrician should install and

test all electrical circuits.

4. Check to ensure that your power source is adequate

to handle the pump amperage as noted above and on

the pump nameplate. Ensure that the electrical supply

circuit is equipped with fuses or breakers of the proper

capacity.

5. A separate 115V branch circuit should be installed for

the control circuit. We do not recommend splitting

the incoming pump power circuit to power the control

circuit.

6. All electrical connections should be tested to ensure

that a proper ground has been established

3 Installation Instructions

1. Excavation: Excavate the hole for the basin as small as possible, with a minimum base diameter of 50”. Never

place the basin in direct contact with rocks or other sharp objects. Place enough fine, 1/8" to 3/4" pea gravel or

1/8" to 1/2" washed, crushed stone at the bottom of the excavation to create a minimum of 12 inches stone or

gravel after compaction. 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. If a concrete pad will be used under the

basin, the compacted stone sub-base can be reduced to 6 inches.

2. Connections & Backfill: Pour enough concrete over and around the anti-floatation flange to anchor the basin

and prevent upward movement. Connect 2” schedule 80 PVC pipe to the pump discharge. Do not reduce the

size of the discharge piping, and do not increase the discharge piping to larger than 3”. The remainder of the

discharge line should be as short as possible with a minimum number of turns. Connect the inlet line to the 4”

inlet hub with a rubber donut (Liberty #6112000). Connect the electrical coupling to 2” electrical conduit and run

the power and float cords through the conduit to the control panel. The remaining backfill should be only fine, 1/8"

to 3/4" pea gravel or 1/8" to 1/2" washed, crushed stone. Do not use sand or native soil as backfill*. Do Not exert

heavy pressure or run heavy equipment over the backfill material, as it may cause tank collapse.

*Other backfill options may be available – consult the factory for special instructions relative to your situation.

3. Venting: The fiberglass basin provided

with the system must be completely sealed

and properly vented in order to meet health

and plumbing code requirements. The

system is designed to be vented through

the inlet to an existing building vent stack.

In order to accomplish this, there must be

no traps between the system inlet and the

nearest building vent stack connection.

See Figure A for an example. If this is not

possible or desirable in your application, a

vent flange or grommet can be installed in

a hole cut into the solid fiberglass cover.

Figure A – Inlet Venting

4. Control Panel:

Risk of Electric shock: This pump is supplied with a grounding conductor. To reduce the risk of

electric shock, be certain that it is connected only to a properly grounded earth wire. All electrical circuitry should be

installed in accordance with the National Electric Code (NEC) and all applicable local codes or ordinances.

The control panel that is an integral part of this complete unit is supplied with its own separate

Installation/Operation/Maintenance manual. Ensure that you have received this manual, and that you read and

understand it prior to installing this unit. Your familiarity with the control panel manual is critical.

A separate 115V branch circuit should be installed for the control circuit. We do not recommend splitting the

incoming pump power circuit to power the control circuit. Connect the grinder pump leads and the float switch leads

to the control panel in accordance with the instructions included with those units.

5. Float Switches: The float switches are pre-mounted on a quick tree. For quick tree removal, loosen the cord nut

and pull the tree straight out of the tank. The pump cycle is pre-set at the factory at 12” for D3648 (approximately

53 gallons) and 18” for D3672 (approximately 79 gallons). The pump cycle can be adjusted by loosening the cord

clamp and moving the “on” float up or down. We do not recommend adjustments of more than 3” in either

direction – please call the factory if you need to adjust the pump cycle beyond this recommended level.

6. Testing and Startup: Follow the testing and startup procedures found in the grinder pump and control panel

manual.

4 Maintenance and Troubleshooting

The grinder pump and control panel are supplied with their own separate

Installation/Operation/Maintenance manuals. Ensure that you have received these manuals, and that you read and

understand them prior to installing this unit. Your familiarity with the grinder pump manual and the control panel manual is

critical. Please follow the Maintenance and Troubleshooting procedures provided in those manuals.
