INSTALLATION
min. above the discharge tee of the DC backup pump (see figures 1 and
2). Position pumps in the sump and move float up and down, making
sure of free movement without interference from any obstructions inside
the sump or lid. Very shallow sumps may require some adjustment to
avoid overfilling or backing up of water into the sump inlet. The float
switch can be moved on the discharge pipe or the rubber stops can be
adjusted as necessary. Cut extra float rod length below lower float stop
to prevent debris from interfering with float operation.
11. Install DC charger (see figure 3) by using anchors provided. If more
convenient, the charger may be set on a nearby shelf or ledge. The
charger should be located 3 or 4 ft. above the sump. Then, remove
protective screen from the front of the charger.
12. Connect the leads from the control charger to the battery terminals.
Positive (+) lead to positive terminal and black neg. (-) lead to negative
battery terminal. Upon proper connection, test alarm will momentarily
sound. This indicates proper charger to battery connection.
CAUTION
Correct battery hook up is essential for operation of
the system. Use wing nuts supplied with battery and eyelet connectors
on battery wire leads. The positive terminal is the larger stud, 3/8"
diameter. The smaller stud, 5/16" diameter is the negative terminal.
Apply grease to the terminals to help prevent corrosion.
13. Connect the black lead from the pump to the negative (-) battery
terminal. Connect the white lead from the pump to the white lead
from the switch. This connection is made at the fuse installed on the
switch wire (see figure 3). Connect the black lead from the switch to the
positive (+) battery terminal.
14. Connect the green sensor wire to the sensor connector (figure 3).
15. Close battery box and secure cover. Carpeted or wood barrier between
the battery case and the floor is recommended.
16. Plug the charger's cord into charger and the 115V wall outlet. The primary
sump pump and the control box should be on separate circuits.
17. Reconnect power to primary sump pump.
18. Optional: A dongle may be used to input a name and number into the
charger for service information to the end user.
19. Optional: On the bottom of the charger there is a pair of dry contacts
to signal an auxiliary device of a low battery, high water and reverse
polarity alarm condition. This simple 2-wire connection is rated at a
maximum of 24V AC/DC and 0.5 amps. It can be used with an auto-
dialer (such as the Zoeller 10-2616), alarm or home security system.
Read the auxiliary equipment's documents for further instructions.
1. The preferred method of installation for backup pumps is shown in
Figures 1 and 2. The installation kit includes the necessary fittings and
one check valve for installing with the backup pump discharging into the
primary pump outlet pipe. An additional check valve is incorporated in the
discharge of the backup pump.
NOTE: Do not install in small spaces where the charger will not be
properly cooled.
2. Remove all parts from shipping carton and make sure all parts are
included. Refer to checklist on page 3.
3. Select location for battery and control charger. Control charger must be
within 6' of a 115V wall outlet and within 6' of pump and basin. Connect to
a separate circuit, different than the primary pump.
4. If primary pump is installed, disconnect power.
NOTE: Discharge piping must be 1-1/2" SCH 40 PVC
a. If the primary pump is submersible, and you are installing per Figure 1,
mark the discharge pipe 7" above the top of the primary pump and cut the
discharge at that location.
b. If the primary pump is a column pump with adjustable
on
position,
and you are installing per Figure 2, check the
on
point and adjust to
approximately 7-1/2" from the bottom of the primary pump. Mark the
discharge pipe 7" above the
on
position of the primary column pump and
cut the discharge pipe at that location.
5. Remove the discharge pipe from the pump and put to the side.
6. Solvent weld the DC pump to supplied tee as shown in Figure 4.
note: Pump must be at a 30° angle to avoid air locking.
7. Install in-line check valve into primary pump discharge. Next, solvent
weld the DC pump to the discharge cut in Step 4. Be sure to orient as
shown in Figure 1 and 2.
8. Measure between the in-line check valve and tee. Use that measurement
to cut discharge pipe. Solvent weld that piece first to the tee. Finally,
connect the discharge pipe to the in-line check valve and tighten straps.
See Figure 4.
NOTE: Check float operations to ensure the strap screws do not interfere
with the float operation of the primary pump.
9. Assemble the float assembly per figure 5.
10. Install the float switch assembly bracket above the outlet tee using the
clamp provided (see figures 1 and 2). Make certain the clamp is tight on
the pipe to avoid slippage. Use electrical tape below the clamp to help
prevent the clamp from moving. Ensure that the “off” level of the float is 1"
INITIAL START-UP AND OPERATION
1. Test the installation for leaks by running water into the sump allowing
for normal operation of the primary pump.
2. Check the control charger. The “red” power on light will be lit when the
unit is plugged into the 115V wall outlet. The
charged/charging
lights will
indicate the condition of the battery when the charger has AC power.
3. Disconnect primary pump before touching any component in the sump pit.
4. Lift float switch. The DC backup pump will run and the alarm will sound.
Lower float switch immediately after alarm has sounded. Pump is running
dry during initial check for several seconds.
CAUTION
Continuous
dry running may cause overheating and damage the pump seals. Upon
release of the float switch, the pump will shut off. Press the reset button
to turn the alarm off.
5. Complete the final testing of your installation by ensuring the primary pump
is still disconnected from the power. Then, unplug the charger from the
115V wall outlet. Run water into the sump until the DC backup pump
is activated by the float switch. Check all connections for leaks.
6. Push alarm reset switch when pump is running. This will silence the alarm.
The pump will continue to run.
7. Reconnect the charger and your primary pump to the AC wall outlets. The
primary pump should come on and lower the water level in the sump
back to the normal operating level and shut off. Use the alarm reset
button to reset the high water light. Both primary and backup systems
are now ready for use.
8. The battery charged and charging LED’s will alternate during normal
charging operation.
NOTE: See page 7 for a description of charger functions.
The DC controller is equipped with a 10 amp charger for maintaining the battery in a ready state and recharging the battery after use when AC power
is restored. Time for recharge depends upon the amount of power consumed by the pumping cycle during the AC power interruption. The pump may
go back to the ready run position in a very short period of time. A completely drained battery may require up to 24 hours for full recharge. If battery
does not charge properly, the LCD will display BATFAIL and the alarm will sound.
