1. Unplug the PS/BC.
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. Check for proper pump operation.
BATTERY TEST
1. Unplug AC power.
2. Fill sump with water. Pump will start
automatically when water reaches
edge of filter cap.
3. If low battery light (yellow LED)
illuminates, batteries should be
replaced. Replace batteries as a set.
