A newly filled battery will sometimes require
additional acid after about 20 minutes. Re-
examine the fill level, and add additional acid if
necessary. The battery acid may bubble at this
time and give off a sulfur-like smell, but this is
normal. You may top off each cell with a little
distilled water, if needed. After the battery has
been filled, screw the six (6) caps securely on
the top of the battery.
The battery will be charged 70%-80% 30
minutes after adding the acid. The system will
then finish charging the battery. During this
time the alarm may sound. The alarm will shut
off within 24 hours.

When you fill the battery for the FIRST time,
it will be the ONLY time you add acid to the
battery. In the future, when the fluid level
is low, add distilled water to the cells.
NEVER add more acid.

If your battery looks like the battery above,
follow these instructions:

1. Remove the cover of the battery box by

pushing in the tabs on the front and back of
the box and lifting up.

2. Place the battery box on the floor. Place the

dry (unfilled) battery into the battery box.
Remove the two battery caps by carefully
prying them up with a screwdriver as shown
on the right. Place the screwdriver in the
middle of the cap on the top of the battery.
DO NOT lift the cap by prying it up from the
groove on the back of the battery cap. It may
damage the vent.

3. Carefully push in the perforated tab at the top

of the acid pack. Lift up the large tab and pull
out the dispensing hose. Hold the hose
upright above the pack and squeeze the hose
forcing all the acid back into the pack.

4. Position the acid pack and battery as shown at

the right. Pinch the end of the hose together
and cut off the tip. Insert the end of the hose
into each cell. Control the flow by pinching
the hose with thumb and forefinger. Fill each
cell of the battery to a level just covering
the battery plates, and then go back and
top off each cell equally. It is important to
have all the cells filled equally or the
battery will not operate properly. The acid
should reach a level about ¼” below the cap
ring as shown in the diagram at right. DO NOT
OVERFILL THE BATTERY. (Diagram E)

Control Unit Connections

Risk of electrical shock or battery explosion,
which can cause serious injury or death.
Unplug the main AC pump to avoid electrical
shock. Wear eye protection. Work in a well-
ventilated area. Do not smoke or allow a
spark or flame in the vicinity of the battery.
Avoid dropping metal tools on the battery.
If battery acid contacts eyes, flush with
water for 15 minutes and get prompt
medical attention. Review the safety
instructions on page 1.

Position the control unit in a secure place
approximately four (4) feet above the floor. Be
sure the power cord will reach the AC power
outlet, and the pump and the float switch will
reach the bottom of the sump pit. Position the
unit in a well-ventilated area. Do not place
anything on top of the battery. Do not place
anything on top of the control unit. (Diagram F)

1. Positioning the dual float switch: The float

switch will turn on the pump when the water
raises either float, and it will remain running
as long as the water is above the float. When
the water drops below the float switch, an
internal timer in the control unit will keep the
pump running an additional 25 seconds to
empty the sump pit. The switch should be
mounted about six (6) inches above the water
level line in the sump pit. Attach the float
switch very securely to the discharge pipe
with the plastic wire tie. Be sure the switch is
