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.

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.
