This document is an Installation, Operation, & Maintenance Manual for the Deming® Series 4507 Sump Pump, specifically for 2, 3, 4, and 6-foot models. It is noted that the product is discontinued and parts may not be available.

Function Description:

The Deming Series 4507 is a sump pump designed for various applications, as indicated by its installation, operation, and maintenance manual. Sump pumps are generally used to remove water that has accumulated in a sump pit, commonly found in basements or crawlspaces, to prevent flooding. Given the "Installation, Operation & Maintenance Manual" title, it provides comprehensive instructions for setting up, running, and servicing the pump to ensure its longevity and efficient performance. The manual emphasizes safety precautions, proper installation, and regular maintenance to prevent equipment problems and ensure safe operation.

Pump Types: The manual illustrates two types:
- Type A: Furnished with a split cover plate, complete with a discharge pipe extending through the plate. This type is shown in the exploded view.
- Type B: Furnished without a cover plate and without a discharge pipe, arranged so the unit can be placed on the floor of the pit.
Discharge Pipe: The discharge pipe (161) is a critical component for expelling pumped fluid.
Suction Head Strainer (316): Prevents large debris from entering the pump.
Float Switch (535): Indicates automatic operation, controlling pump on/off cycles based on liquid level.

Usage Features:

Automatic Operation: The presence of a float switch (535) and float rod (529) indicates that the pump is designed for automatic operation, turning on and off based on water levels in the sump pit.
Installation Flexibility: The availability of Type A (with cover plate and discharge pipe) and Type B (without cover plate and discharge pipe for pit floor placement) suggests adaptability to different installation scenarios.
Motor Rotation: Requires checking motor rotation before permanent power connections, ensuring clockwise rotation when viewed from the motor.
Impeller Adjustment: The impeller clearance can be adjusted to compensate for wear, extending the pump's operational life. This involves loosening specific nuts and screws to seat the impeller properly.
Dismantling and Assembly: Detailed step-by-step instructions are provided for both dismantling and assembling the pump, facilitating repairs and part replacements. Key steps include disconnecting discharge lines and wiring, removing the base and strainer, disassembling the impeller and shaft, and reassembling components in reverse order.
Safety Precautions: The manual extensively covers safety, including warnings about electrical shock, rotating machinery, hot surfaces, hazardous fluids, and proper lifting techniques. It mandates that only qualified personnel install, operate, and repair the pump and that all wiring conforms to NEC or CEC codes. Ground fault circuit interrupters (GFCI) are recommended for plug-in type power cords.
Warranty: A "Limited 24 Month Warranty" from Crane Pumps & Systems covers defects in material and workmanship under normal use and service, starting from the manufacture date. The warranty specifies conditions, limitations, and the process for making claims. It explicitly states that the warranty is void if damage is caused by improper installation, voltage, lightning, abrasive material, or chemical content, or if the original equipment is modified.

Maintenance Features:

Lubrication: Motor bearings require lubricant, with a recommendation of five to ten drops of good grade mineral oil annually. The thrust bearing (18) should be periodically greased with a quality grade of light grease.
Impeller Adjustment: As mentioned, the impeller can be adjusted to maintain optimal clearance and performance.
Inspection: Regular inspection is crucial. For example, the lower bearing bushing (39) should be inspected for wear during dismantling and replaced if necessary. Cable protection and frequent inspection are also advised.
Cleaning: Products returned for service must be cleaned, sanitized, or decontaminated to ensure employee safety.
Storage: Instructions are provided for both short-term (up to 6 months in a dry atmosphere with constant temperatures) and long-term (up to 24 months in a temperature-controlled, roofed enclosure between +40°F and +120°F) storage. For long-term storage, rotating the impeller by hand before initial startup is recommended to ensure free movement.
Troubleshooting/Reference: The "Start-Up Report" section serves as a checklist for installation and initial operation, documenting critical parameters like electrical readings, pump condition, and operational checks. This report is intended to be retained by all parties for future troubleshooting and reference.
Discontinued Product Note: The prominent "DISCONTINUED - Parts may NOT be available" warning on the front page is a critical maintenance consideration, indicating potential challenges in sourcing replacement parts for repairs. This implies that users should be aware of the limited availability of components for this specific series.
