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. 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 below. DO NOT

OVERFILL THE BATTERY. (Diagram E)

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. After the battery has been filled, press

the caps securely on the top of the battery.

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.

Battery Maintenance

Measuring the battery fluid level is one of the

most important features of the system. It is

important to check the battery fluid levels at

least once every 4-6 months. Detailed

instructions on adding distilled water to the

battery can be found within the Understanding

the Warnings & Alarms section of this manual

(page 13,

Water). If you are not using a

Basement Watchdog standby battery, you cannot

use the battery fluid sensor. You will need to

attach the fluid sensor to the POSITIVE (+) post

of the battery or the alarm will sound

continuously. The system will NOT warn you if

the fluid level is low in this configuration. You

will need to check your battery every couple of

months to see if it needs water. If the battery

dries out, the system will not work. If you are

using a maintenance free battery or sealed AGM

battery you will also need to attach the fluid

sensor to the POSITIVE (+) post of the battery or

the or the alarm will sound continuously.

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.

When you position the battery with the control

unit on the top, be sure the charger cord will

reach the AC power outlet, and the pump cable

and the float switch will reach the bottom of the

sump. Position the unit in a well-ventilated

area. (Diagram F)

1. Positioning the dual float switch: The float

switch will activate 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

positioned vertically

with the mounting

bracket at the top.

Do not tilt the switch. Do not position the float

switch on the side of the discharge pipe facing

the drain tile or any incoming rush of water!

2. Connecting the pump: Remove the security

tag from the pump and plug the pump wires

into the pump connector on the back of the

control unit. Keep the backup pump wire, the

AC pump wire, and the float wire separate

from each other. Do not let them cross on the

final installation.

3. Installing the battery fluid sensor:
