ELECTRICAL CONNECTIONS
Hazardous voltage. Can cause serious or
fatal electrical shock. Never operate charger unless it is
grounded.
The charger has a three-prong electrical plug. Use it only
in a grounded, grounding type outlet. Do not remove the
third (ground) prong. Do not use an extension cord.
If your outlet is not grounded, install a copper wire (at
least 14 gauge) from the outlet box to a cold water pipe.
Use ground clamp on pipe. BE SURE that the cold water
pipe used has metal continuity to electrical ground.
CHARGER/BATTERY INSTALLATION
1. Connect charger as shown in Figure 2.
A. Connect Positive (+) lead from charger to positive
battery post.
B. Connect Negative (–) lead from charger to negative
battery post.
C. Third lead from charger is factory connected to
lead from pump motor/float switch.
NOTICE: If charger is connected backwards, pump
will not operate properly, battery will not charge,
and “Charging” light will not come on. However,
no actual damage will be done to unit.
2. Plug in power cord to a 115-125 Volt AC outlet deliv-
ering at least 2 amps. Do not use a switch controlled
outlet. Mark circuit in main power panel “Backup
sump pump power supply; do not turn off”.
NOTICE: Alarm may sound when unit is first installed.
If so, reset it.
3. With charger properly connected and plugged in and
power ON, red light on front panel will be ON (See
Figure 3). If a battery has been connected to charger,
either yellow or green light on panel will also be on
(see Figure 3).
A. If battery is fully charged, green light (CHARGED)
will be ON.
B. If battery is being charged, yellow light (CHARG-
ING) will be ON.
4. When charger is plugged in, battery is connected, and
unit is operating properly, two lights will always be on
– the red POWER ON light and either the yellow
(CHARGING) light or the green (CHARGED) light.
NOTICE: During normal operation, the charger con-
stantly monitors the battery voltage, which can cause
the green and yellow lights to flash alternately. The
rate at which they flash may vary, depending on the
condition of the battery.
BATTERY MAINTENANCE
NOTICE: To protect battery case from chipping and
gouging, do not let battery sit on concrete floor. Install
battery on a shelf or protective pad (plywood, 2x4s, etc.).
Always install battery in a dry location that is protected
from flooding.
Every three months, check battery as follows to maintain
battery in best condition:
1. Unplug battery charger.
2. On batteries with removable top caps, measure
specific gravity of the electrolyte. Use a hydrometer
(available at auto parts stores). If the specific gravity of
any cell is less than 1.225 or if there is more than .050
variation between cells, replace the battery.
3. Check electrolyte level and refill as needed.
4. Check battery terminals and clamps for tightness and
corrosion. Clean and tighten as needed.
5. Plug in battery charger.
