1 General Information

Maximum fluid temperature: 140F (60C)

The LSG or LSGX Series 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 [phone] or visit

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 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 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 system 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
alarm. 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
