Maintenance
lways 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.
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: n 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.

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.
void dropping metal tools on the
battery posts because they may spark
or short-circuit the system or battery,
causing an explosion.
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.
