The DC controller is equipped with a 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 LED battery will flash red.

Head
The DC emergency pump system requires a good quality, 12 volt battery
to obtain maximum pumping time during a power outage. A deep-cycle,
12 volt, 105 amp-hour marine battery or larger is recommended and will
provide approximately 5 hours of continuous pumping time in a sump pump
installation with 8' (2.4 m) of head pressure. In most installations, the pump
runs intermittently and the battery life is extended accordingly. Batteries
with top terminals are recommended for ease of installation. "Wet" cell
batteries contain acid, and proper precaution must be taken when handling.
Battery box will accommodate a maximum battery size of 13-1/2" (34.3 cm)
Length x 7" (17.8 cm) Width x 9-1/2" (49.5 cm) Height. AGM batteries also
recommended. Do not use gel batteries or automotive batteries.
INSTALLATION
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" (10 mm) diameter. The smaller stud, 5/16"
(8 mm) diameter is the negative terminal. Apply grease to the
terminals to help prevent corrosion.
7. Connect the plugs for the pump, and operational switch into the
appropriate recepticles on the controller.
8. Plug the controller into the 115 V wall outlet. The primary sump
pump and the controller should be on separate circuits.
9. Reconnect power to the primary sump pump.
High water reed sensor
If using the optional high water sensor, install it with the "on" level
set at least 1" above the "on" level of the operational float using
the supplied bracket and clamp. Move the switch up and down,
ensuring free movement without interfence from any obstructions
inside the sump or lid.
The controller will alarm and run the pump if the high water
sensor's float is "up". If the high water sensor should no longer be
monitored, perform a factory reset by holding both buttons (silence
and test) on the controller for 5 + seconds.
1. Ensure O-ring is properly located on pump discharge. Slide DC pump
into fitting and tighten the hose clamp.
2. The preferred method of installation for backup pumps is shown in
Figure 1. The installation kit includes one threated check valve to be
used in the discharge. An additional check valve is incorporated in
the discharge of the backup pump.
3. Select location for the battery and the controller. The controller
charger must be within 8' (1.87 m) of a 115 V wall outlet and within
6' (1.8 m) of pump and basin. It is recommended that the controller
is plugged into a separate circuit, different than the primary pump.
4.
Make certain the float switch clamp is tight on the pipe to avoid
slippage. Ensure that the “off” level of the float is 1" (25 mm) min.
above the discharge tee of the DC backup pump (see Figure 1).
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.
5. Install the Spin
™
controller (see Figure 3) by using the anchors
provided. For best cooling, install wall mount configuration. The
controller should be located at least 3' (1 m) above the sump.
6. Connect the leads from the controller to the battery terminals.
Positive (+) lead (white wire) to positive terminal and black neg. (-)
lead (black wire) to negative battery terminal.
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 controller. The System Ready light will be green when
the unit is plugged into the 115 V wall outlet. The battery will
indicate its condition when the controller has DC power. When
the unit is first plugged in, all lights will flash and alarm will sound
to verify all lights and the alarm work.
3. Disconnect the primary pump from its power source before
touching any component in the sump pit.
4. Lift the operational float switch. After a couple seconds the DC
backup pump will run, and the alarm will sound after about 1
second. Lower the operational float switch after the alarm sounds.
Take care that the intake of the DC pump is set above the inlet
of the primary pump. Press silence for 3 seconds to clear out the
alarm and reset the unit.
CAUTION
Continuous dry running may cause overheating and
damage the pump seals. Upon release of the float switch, the
pump will shut off. Be sure there are no obstructions around the
float.
5. Complete the final testing of your installation by ensuring the
primary pump is still disconnected from power. Then, unplug the
fit controller from the 115 V wall outlet. Run water into the sump
until the DC backup pump is activated by the operational float
switch. Check all connections for leaks.
6. Push the silence button when the pump is running. This will silence
the alarm. The pump will continue to run until the operational float
is deactivated.
7. Reconnect the controller and the primary pump to the AC wall
outlets. The primary pump may come on, lower the water level
in the sump back to its normal operating level, and shut off. Both
primary and backup systems are now ready for use. Hold silence
button for several seconds to reset the unit.
8. Hold the silence button for several seconds to reset the unit. LED
will be yellow during normal charging operation. See page 6 for
a description of controller functions.
NOTE: When running the pumps, it is normal for a stream of water
to spray out of the 1/8" (3 mm) air relief hole.
Note: In order to provide an alarm when the switch is disconnected,
the controller supervises the operational switch connection. It
does not supervise the optional tight water sensor connection
until a high water sensor is plugged into the controller.
