EXPLODED VIEW - DC PUMP
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 float operation.
Install the high water switch with the "on" level set at least 1" (2.5 cm)
above the "on" level of the operational float using the supplied clamp.
Move the switch up and down, ensuring free movement without
interference from any obstructions inside the sump or lid.
11. Install the Fit 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.
12. Connect the leads from the controller to the battery terminals.
Positive (+) lead to positive terminal and black neg. (-) lead to
negative battery terminal.
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. The stud sizes on some
batteries may be identical. Apply grease to the terminals to help
prevent corrosion. Tighten slightly past finger tight with a wrench.
Always use extreme caution around batteries. Be careful not to
“cross” or “short across” the battery terminals with your wrench or
any other metal object.
13. Connect the DC pump's plug into the controller terminal.
14. Plug the controller into the 115 V wall outlet. The primary sump pump
and the controller should be on separate circuits.
15. Reconnect power to the primary sump pump.
16. The Aquanot
®
Fit Controller is designed for use with Z Control
®
.
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.
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
INSTALLATION
