Control Box Installation - Wayne ESP25 Instrucciones De Funcionamiento Y Manual De Piezas

Method 2
If a separate, dedicated discharge is not possible as in
Method 1, the back-up pump can be tied into the AC
operated pump's discharge pipe by installing a "Y"
connector. Two check valves will be required.
1. Locate the back-up pump on a solid, level surface in
the sump pit. Do not place the pump on a loose or
sandy surface. Small stones or sand may damage the
pump resulting on potential pump failure.
2. This pump has a 1 1/2" NPT discharge. If a 1 1/4"
discharge pipe is desired, an adapter (not included) will
be necessary. Smaller piping will reduce pump flow,
rate and performance.
3. A check valve will be required in the discharge line
of BOTH the Main AC pump and the back-up pump to
prevent recirculation of water into the sump pit.
System will not function without two check valves.
4. Cut a 4' section of 1 1/4" or 1 1/2" diameter rigid PVC
pipe. Cement 1 1/4" pipe to a threaded fitting. Cement
1 1/4" pipe into pipe coupling. Attach 1 1/4" pipe
section to the back-up pump discharge adapter.
5. Screw on to pump discharge.
Be careful NOT to strip or cross
thread plastic fittings or check valves.
Flex hose is NOT recommended. Rigid PVC or metal pipe is
required for permanent installation.
6. Place the pump with the 4' section of PVC pipe on the
sump floor or on an elevated surface if required.
7. Attach a rubber check valve (sold separately) to the top
of the discharge pipe. This will allow the pump or
check valve to be removed easily for servicing.
8. Duplicate the discharge piping arrangement for the
primary AC pump if the discharge line has to be
adjusted to accomodate a second pump.
9. Glue a 45º elbow to the short pipe on the back-up
pump. Glue a "Y" adapter to the short pipe on the
existing pump, as shown in illustration for Method 2.
10. Glue a short piece of PVC pipe between the 45º elbow
and the "Y".
NOTE: Check valves can be placed directly in the pump
discharge if desired. However, for ease of disassembly, it is
recommended that check valves be placed above the sump
as shown in Figure 2.
The remainder of the discharge pipe installation will
vary depending on individual circumstances. Using sound
plumbing practices, route the discharge pipe to an exterior
wall by the shortest distance.
Methods 1 and 2
Install float switch at least 10"-12" above bottom of sump
pit so that back-up unit turns on only when the water

level is higher than the normal "on" level for main pump.
Use the wire ties provided to secure the switch to the
discharge pipe. Make sure power wires do not interfere
with float switch, pump inlet, or main pump operation.
Back-up pump must not be allowed to run dry.

Control Box Installation

1. Place battery in box, attach red
cable to positive battery post and black cable to
negative battery post.
If cables are reversed, damage to the
control box or battery COULD result,
and warranty will be void.
2. Plug the float switch, pump and transformer into the
appropriate connectors. The connections are all
unique and cannot be interchanged.
3. Put lid on box, and place the battery within six feet of
the sump and a 115 VAC separately fused outlet. The
outlet must be protected by a ground fault circuit
interrupter (GFCI) The area must also be clean, dry and
well ventilated.
