Maintenance
Always disconnect the electrical supply before attempting to install, service, relocate or per- form any maintenance. If the power source is out of sight, lock and tag in the open (off) position to prevent unexpected power application. Failure to do so could result in fatal electrical shock. Only qualified electricians should repair this unit. Improper repair could result in fatal electrical shock.
Once a month, check battery condition. To check battery condition follow steps listed below:
1.Unplug the wall charger.
2.For batteries with top caps that can be removed, the electrolyte level should be checked and filled to manufacturer’s specifications. The charge for each cell should be checked with a hydrometer. A specific gravity of 1.265 indicates the battery is at full charge. If the specific gravity of any of the cells varies more than .050, the battery should be replaced.
NOTE: An inexpensive hydrometer can be purchased at an automotive parts dealer.
3.Inspect the terminals and clamps for corrosion and tightness. Clean and tighten as required.
4.Unplug the main pump and fill sump with water until back up pump turns on. Repeat process two times to be sure pump is operating normally.
5.If pump operates normally, plug charger into wall outlet, turn on main pump. If pump fails to operate normally, see Troubleshooting guide and correct problem. Repeat step 5.
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.
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
Follow battery manufacturer’s maintenance procedures and schedules. 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.
