CHARGER/BATTERY
INSTALLATION
NOTICE:
An alarm, located in the junction box, automati-
cally sounds when the system runs if the alarm is in the
“Enable” position. The alarm is silenced when the alarm
switch is in the “Disable” position.
1. Apply two pieces of two-sided tape (provided, Key No.
11, Page 9) to the back of the junction box. Press the junc-
tion box onto the battery box as illustrated in Figure 5
(below) and on Page 9 (Exploded View).
2. Connect the charger as shown in Table I and Figure 5.
3. Plug the charger into a 115-120 Volt AC outlet delivering
at least 15 amps.
Do not use a switch controlled out-
let.
Mark circuit in main power panel “Backup sump
pump power supply; do not turn off”.
4. With the charger properly connected and plugged in, the
panel on the front of the charger will show one of the fol-
lowing conditions (See Figure 6).
