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.

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, 90 amp-hour or larger marine battery is recommended. A 100+ amp
hour battery will provide approximately 5.5 hours or more 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" (24.1
cm) Height. AGM batteries also recommended. Do not use gel batteries
or automotive batteries.

Slide the DC pump into the fitting, and tighten the hose clamp. Soapy
water is recommended as a lubricant.
NOTE: The pump must be pushed all the way into the fitting to prevent
the fitting from leaking. Place the clamp at the edge of the fitting so
that the slotted sections can sufficiently tighten around the pump
discharge.
8. Measure, cut and solvent weld any remaining discharge piping
above the tee.
NOTE: Check float operations to ensure the hose clamp screws will
not interfere with the float operation of the primary pump.
9. Assemble the operational float assembly per Figure 3. Install float
switches as seen in Figure 1. The top rubber stop is not needed
unless the "on" level needs to be lowered.
10. Install the operational float switch bracket above the "on" level of
the primary pump using the clamp provided. Make certain the clamp
is tight on the pipe to avoid slippage. Ensure that the "off" level of
the float is 1" (2.5 cm) minimum above the outlet of the DC backup
pump. Position the pumps in the sump and move float up and down,
ensuring free movement without interference from any obstructions
inside the sump or lid. The float switch can be moved on the
discharge pipe, or the rubber stops can be adjusted as necessary.
The top rubber stop is usually not needed. Cut off any extra float rod
length below lower float stop to prevent debris from interfering with
1. The preferred method of installation for backup pumps is shown in Figure 1.
The installation kit includes the parts needed to install as in Figure 1. A
check valve is incorporated in the discharge of the backup pump.
NOTE: Do not install in small spaces where the controller will not be
properly cooled. Do not operate in > 80
º
F environment.
2. Remove all parts from the shipping carton, and make sure all parts are
included. Refer to the parts list on page 3.
3. Select a location for the battery and the controller. The controller must
be within 8' (2.4 m) of a 115 V wall outlet and within 6' (1.8 m) of pump and
basin. Connect to a separate electrical circuit from the primary pump.
4. If the primary pump is installed, disconnect power.
NOTE: Discharge piping must be 1-1/2" SCH 40 PVC
5. Remove the discharge pipe from the pump and place it aside.
6. Screw check valve assembly into the primary pump discharge. Ensure
the O-ring is properly located on the check valve. Press the slotted end
of the discharge tee onto the check valve and secure with a hose clamp.
Soapy water is recommended as a lubricant.
NOTE: The tee must be pushed all the way down onto the check valve to
prevent leaking. Place the hose clamp at the bottom edge of the tee so
that the slotted sections can sufficiently tighten around the check valve.
7. Solvent weld the discharge reducer fitting to the discharge tee as shown
in Figure 4. Ensure the O-ring is properly located on the pump discharge.
