use an adapter.

! WARNING Support pump and piping when assembling and after installation. Failure to do so could cause piping to break or pump to fail, which could result in property damage and/or personal injury.

5. Set pump into sump. Locate the pump on a solid level surface.

NOTICE Do not place directly on clay, gravel, or any loose or sandy surfaces. These surfaces con- tain small stones or sand that may clog or damage the pump, which could result in pump failure causing flooding and property damage.

6. This pump has a 1-1/2” NPT discharge. If existing piping is 1-1/4” NPT, an adapter bushing (not included) may be used. Do not use piping that is less than 1-1/4” NPT. Piping that is too small will result in reduced output.

7. A check valve is required in the discharge line to prevent backflow when the pump shuts off. It is best to install the check-valve directly to the pump discharge. Thread a check valve into pump dis- charge.

Never cut off grounding prong or

! WARNING

SP-330, SP-330D, SP-500, SP-500A Submersible Sump Pumps

	NOTICE	Be careful not to strip or cross-
thread. Do not use pipe joint sealant.
	NOTICE	Flexible discharge hose is intended

for temporary use only. Rigid PVC or metal pipe is required for a permanent installation. If flexible dis- charge hose is temporarily used, make sure pump is secured in sump pit to prevent movement. Failure to secure pump could allow pump movement and cause switch interference and prevent pump from starting or stopping. This could result in flooding and property damage.

IMPORTANT! Make sure there is adequate room for float switch to move freely during operation. A 1” minimum is required.

8.Connect 1-1/4” diameter rigid pipe to rubber boot on check valve (not included). Reverse boot for 1- 1/2” diameter pipe. Tighten clamps.

9.Insert the pump cord plug directly into 115 volt grounded electrical outlet that is protected by Ground Fault Circuit Interrupter (GFCI) (Figure 1).

!WARNING When routing electrical cord protect cord from sharp objects, hot surfaces, oils, and chemi- cals. Do not kink cord, replace any damaged cord immediately.

Unit should be plugged into outlet as shown in figure 4. Do not plug alarm box in upside down. Doing so may cause the pump to unplug. If the outlet is upside down, have a qualified electrician reposition the outlet before installing the unit.

Testing

1.Fill sump pit with water.

2.While the pump is draining the pit, verify that the discharge piping is carrying the water to a point at least 15 feet away from the foundation.
