2. Precautions/Pre-Installation

1. Inspect all materials for shipping damage and to ensure that all parts have been received. 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 - See "Note" under pump specifications.
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 should 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.
Never remove the ground pin from the plug.
4. Make certain that the outlet is within reach of the power supply cord. Never use an extension cord.
5. The power cords from the LowPro system are equipped
with piggyback plugs and must be connected in series to
operate automatically (see fig. 1).
6. Check to ensure that your power source is adequate to
handle the pump amperage.
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.
7. 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.
8. 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.
9. A qualified licensed electrician should install and test all electrical circuits.
10. All plumbing (waste and vent) must be installed to meet local plumbing codes. This unit must be properly vented. Automatic
or mechanical plumbing vent devices must not be used. This pump is not to be installed in a location classified as hazardous

when framing.
4. Determine the closest and most readily accessible locations to tie in the discharge and vent lines to existing lines. Take the
necessary measurements and determine what plumbing fittings and pipes are needed.
5. An inlet for a 2" PVC drain line from additional fixtures (i.e. sink or shower) may be installed using the rubber pipe grommet
(supplied). Determine the best location for the drain line to enter the tank making sure it is within the marked textured areas of the
pump chamber. See fig. 2. Do not drill below or outside of the textured areas. Make sure drain lines have adequate gravity
flow to the system. If a shower is being used, elevate the shower to allow for proper trapping and drainage. Drill a 3" diameter
