1. General Information and Safety Guidelines

2. Installation

Before installation, read the following instructions carefully. Each Liberty pump is individually factory tested to insure proper performance. Closely following these instructions will eliminate potential operating problems, assuring years of trouble-free service.

 Risk of electric shock. Always disconnect the pump from the power source before handling or making

adjustments.

 The electrical connections and wiring for a pump installation should only be made by qualified personnel.  This pump is supplied with a grounding conductor and grounding-type attachment plug. To reduce the risk of

electric shock, be certain that it is connected only to a properly grounded, grounding-type receptacle.

 Do not bypass grounding wires or remove ground prong from attachment plugs.  Do not use an extension cord.  This pump requires a separate, properly fused and grounded branch circuit. Make sure the power source is

properly sized for the voltage and amperage requirements of the pump, as noted on the nameplate.

 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.

 The installation must be in accordance with the National Electric Code and Plumbing Codes as well as all

applicable local codes and ordinances.

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). The DC pump is packaged tilted at 30° angle 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 as part # 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 prevent 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 and not 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. This can also be used for removal of the pump, should the need arise. Do not reduce the discharge size to less than 1-1/4”, as this will affect pump flow and performance.

4. A check valve is already installed on the primary pump as well as the backup pump. Please refer to the 441 installation manual for instruction on the battery backup system.
