Battery Information
(Continued)
Be certain that the area around the batteries is well ventilated. Before servicing the batteries, blow away gasses by waving a piece of cardboard near the batteries.
Dangerous hydrogen gas can be released from batteries while charging. Sparks can ignite the gas in an enclosed space. Wear safety goggles when connecting batteries. Battery connections should be made in a well- ventilated area.
Working in the vicinity of lead acid batteries can be dangerous. Before making connections or servicing the batteries, read and follow instructions in all applicable instruction manuals. To reduce the risk of battery explosion, follow the instructions in this manual and those published by the battery manufacturer, as well as those of any other equipment used in the surrounding area.
Installation
Installation of this unit may take several hours. Before disabling your main pump, have ready an appropriate means of evacuating the sump.
1.Turn power to main pump off.
2.Pump must be installed using 11/4” or 11/2” rigid PVC piping.
Pump Installation
The ESP25 can be installed as a back up system with a separate dedicated discharge line (Method 1), or tied into an existing sump pump line (Method 2, page 3).
Unplug the existing AC pump. Failure to follow this warning could result in fatal electrical shock.
1.Verify that the existing AC pump is in good working order. If the AC pump is questionable, it is typically recommended that the unit be replaced with a 1/3 or 1/2 HP pump.
2.Remove any silt or accumulated debris from the sump pit and surrounding area.
Method 1 (Preferred)
1.Locate the ESP25 on a solid, level surface in the sump pit. Do not place the pump on a loose or sandy surface. Small stones or sand may damage the pump resulting in potential pump failure.
2.This pump has a 11/2” NPT discharge. If a 11/4” discharge pipe is desired, an adapter (not included) will be necessary. Smaller diameter piping will reduce pump flow, rate and performance.
3.Cut a 4’ section of 11/4" or 11/2" diameter rigid PVC pipe. Cement 11/4" pipe to a threaded fitting. Cement 11/4" pipe into pipe coupling. Attach 11/4" pipe section to the ESP25 discharge adapter.
4.Screw on to pump discharge.
An assistant should be present or close enough to come to your aid in the event of an emergency. Have a reliable source of fresh water and soap nearby in case battery acid contacts clothing, skin or eyes.
Wear eye and clothing protection when working around lead acid batteries.
Avoid touching your eyes when working around lead acid batteries.
If battery acid contacts your eye(s), flush with cold running water for 10 minutes and seek immediate medical attention. If acid contacts your skin or clothing, wash immediately with soap and water.
Never smoke or allow a spark or flame in the vicinity of the battery.
Avoid dropping metal tools on the battery posts because they may spark or
