Information
1. General
Before installation, read the following instructions carefully. Each Liberty pump is individually factory tested to ensure
proper performance. Closely following these instructions will eliminate potential operating problems, assuring years of
trouble-free service.
RISK OF ELECTRIC SHOCK
NEVER enter a flooded space without proper
Personal Protective Equipment. Always wear
dielectric rubber boots and other applicable
protective equipment when water is on the
floor and you must service an energized
pump or alarm system.
DO NOT enter the water if the water level is
higher than that of the protection your PPE
offers or if your PPE is not watertight.
DISCONNECT POWER before installing or
servicing this product. A qualified service
person must install and service this product
according to applicable electrical and
plumbing codes.
The electrical outlet shall be within the length limitations of the pump power cord, and at least 4 feet above
floor level to minimize possible hazards from flood conditions.
Failure to follow the above precautions could result in serious injury or death. Replace product
immediately if sensor or power cable becomes damaged or severed. Keep these instructions in a safe
place for future reference. This product must be installed in accordance with National Electric Code,
ANSI/NFPA 70 so as to prevent moisture from entering or accumulating within junction boxes, conduit
bodies, fittings, float housing, alarm enclosure, or cable.
2. Installation
The PC Series includes a primary sump pump preassembled with a DC powered battery backup pump. An exploded
view of the system can be seen on page 3 (Figure 1). PC series with a 441 DC pump have the pump angled at approxi-
mately 30° to help prevent airlock.
1.
This system should not be installed in a sump pit less than 15" in diameter. A larger diameter pit is preferred as it
allows for longer pump cycling and reduced switch cycling. The depth of the pit should be at least 18" above the
surface that the pump is resting on. If the pit is not already enclosed on the bottom, provide a hard level bottom
of bricks or concrete. DO NOT place the pump directly on earth, gravel or debris since this can cause excessive
wear of the impeller and possible jamming. "The Brick" (sold by Liberty Pumps, PN: 4445000) is a pre-molded
stable platform designed to fit your submersible pump. It raises the pump 2.5" off the bottom of the pit, reducing
the potential for jamming from rocks and debris (contact your local distributor to order). Remove all debris from
the bottom of the sump pit before installation of the pump. A sump pit cover is suggested for safety and to pre-
vent foreign objects from entering the pit.
2.
Set the complete system in place by lowering the pump by the handle on the primary pump. Confirm that both
the primary float switch and the backup float switch have adequate clearance and will not hang-up on the pit
wall. The float must be free to move throughout its travel, without contacting the pump body, piping, or other
objects.
3.
The uppermost rubber coupling will connect to 1-1/2" PVC pipe. Tighten clamps to prevent leaking. Do not re-
duce the discharge size to less than 1-1/4", as this will affect pump flow and performance.
4.
Check valves come pre-installed on both the primary and backup pumps. Please refer to the proper installation
manual for instruction on the battery backup system.
