The Liberty Pumps LowPro-Series is a low-profile sewage system designed for residential and commercial applications where a traditional gravity-fed sewage system is not feasible. This compact and fully assembled unit is engineered to efficiently handle wastewater from toilets and other sanitary fixtures, providing a reliable solution for various installation scenarios.

Function Description

The LowPro-Series system is designed to collect and pump wastewater from a toilet, and can also simultaneously receive wastewater from other sanitary fixtures such as a sink, shower, or bathtub. The system operates automatically, activating when the toilet is flushed or when liquid from other fixtures enters the unit. Once the contents are pumped away, the system automatically shuts off. The internal jet spray feature helps break down solids and reduce the risk of jamming, ensuring smooth operation. The system is equipped with a 2-inch solids handling sewage pump, capable of managing typical sewage waste. A cover is provided for easy access to the tank and switch, allowing for maintenance without disturbing the discharge or vent pipe. The design emphasizes a low-profile footprint, making it suitable for installations where space is limited or where the system needs to be discreetly integrated.

Usage Features

The LowPro-Series is shipped from the factory fully assembled and ready for installation, simplifying the setup process. It is designed for ease of use and minimal intervention once installed. The system's automatic operation eliminates the need for manual control, providing convenience for users. It is crucial to adhere to the manufacturer's guidelines regarding the types of waste that can be introduced into the system. While designed to handle toilet waste, it is important to avoid flushing extreme amounts of toilet paper, reinforced papers, paper towels, sanitary products, or other foreign objects, as these can put undue strain on the pump and lead to discharge line blockages or system failure. The system is intended for use with one water closet (toilet) per unit. The compact design allows for flexible installation in various settings, including those where a traditional sewage system might be challenging to implement. The system's ability to handle wastewater from multiple fixtures simultaneously enhances its versatility for different household or commercial needs.

Maintenance Features

Maintaining the LowPro-Series system is straightforward, with several features designed to facilitate easy upkeep and ensure long-term performance. The system's design allows for access to the tank and switch without requiring the removal of discharge or vent piping, simplifying inspection and servicing. Regular cleaning of the LowPro is a routine maintenance task to keep the unit clean and free of objectionable odors. This involves using a damp cloth and a mild household cleaner, avoiding abrasive cleaners or chemicals that could damage the unit. If the unit is a washing machine, periodic removal of the access cover to clean lint and debris from the float switch housing is recommended.

For more in-depth maintenance or troubleshooting, the manual provides detailed instructions. The float switch adjustment diagram guides users on how to adjust the float switch to ensure proper pump engagement and shutdown, typically at waste depths of approximately 4 inches for engagement and 3 inches for shutdown. In case of operational issues, a comprehensive troubleshooting matrix is provided, outlining common problems, possible causes, and corrective actions. This matrix covers issues such as the pump not starting, running but not turning off, running or humming without pumping, and cycling too frequently. For instance, if the pump does not start, the matrix suggests checking for tripped circuit breakers, GFCIs, blown fuses, or obstructions preventing the float switch from moving freely. If the pump runs continuously, it advises checking for obstructions that prevent the float switch from reaching the "PUMP OFF" position or inspecting for a defective float switch.

For problems related to the pump not delivering proper capacity, the manual recommends checking for partially closed or clogged discharge lines, partially clogged check valves, or if the total head (lift height) exceeds the pump's capability. Noisy pump operation might indicate worn bearings, foreign objects in the impeller cavity, or a broken impeller. Repeated tripping of circuit protection could be due to an underrated circuit, other appliances on the same circuit, inadequate wiring, improper voltage, or obstructions in the pump.

It is crucial to note that no repair work should be carried out during the warranty period without prior factory approval from Liberty Pumps, as unauthorized field repairs will void the warranty. For any repairs or service, it is recommended to contact Liberty Pumps to locate an authorized service center. The manufacturer assumes no responsibility for damage or injury due to disassembly in the field by unauthorized personnel. The manual also emphasizes the importance of protecting power and control cords from the environment to prevent water wicking into pump or switch housings, which could energize surroundings. Regular inspection and cleaning of the motor and float switch housing are also recommended to prevent foreign matter buildup.
