Pump Installation - RIDGID XD PRO RBSU25 Operating Instructions And Parts Manual

Model RBSU25 – Operating Instructions and Parts Manual
Wear eye or clothing protection when working around
lead acid batteries. Avoid touching your eyes when
working around lead acid batteries.
If battery acid contacts your eye(s),
flush with cold running water for 10
minutes and seek immediate medical attention. If acid
contacts your skin or clothing, wash immediately with
soap and water.
nEVER smoke or allow a spark or
flame in the vicinity of the battery.
Avoid dropping metal tools on the
battery posts because they MAY
spark or short-circuit the system or battery, causing an
explosion.
Installation
Installation of this unit may take
several hours. Before disabling
your main pump, have ready an appropriate means of
evacuating the sump.
1. Turn power to main pump off.
2. Pump must be installed using 1-1/4" or 1-1/2" rigid PVC
piping.

Pump Installation

The back-up pump can be installed with a separate
dedicated discharge line (Method 1), or tied into an
existing sump pump line (Method 2).
Unplug the existing AC pump. Failure
to follow this warning CoULD result in
fatal electric shock.
1. Verify that the existing AC pump is in good working
order. If the AC pump is questionable, it is typically
recommended that the unit be replaced.
2. Remove any silt or accumulated debris from the sump
pit and surrounding area.
Method 1 (Preferred)
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 in 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 diameter piping will reduce pump
flow, rate and performance.
3. 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.
4. 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.

5. Place the pump with the 4' section of PVC pipe on a
solid, level surface in the sump pit on an elevated
surface.
6. 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.
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 1.
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 path. Keep turns to a
minimum because they reduce flow output of the pump.
The pipe that exits the building structure should be sloped
downward so that water will not freeze in the pipe.
When installing the separate discharge pipe, drill through
the outside wall with appropriate drilling equipment. Seal
the hole to prevent water from entering.
