This extensive description details the specifications, features, and critical warnings for the Hayward Max-Flo XL medium-head pump, model SP2307X10, equipped with the A.O. Smith motor assembly SP2707Z1M.
I. Product Identification and Regulatory Compliance
* Product Name: Hayward Max-Flo XL Pool Pump.
* Primary Model Number (Pump): SP2307X10. This model is categorized as a standard efficient, single-speed, medium-head pump.
* Motor Assembly Part Number: SP2707Z1M (Motor by A.O. Smith, Code C130).
* Intended Use: Specifically engineered for water circulation and filtration systems in residential Inground Swimming Pools, Hot Tubs, and Spas.
* Serial Code: 21121205005633019 (A unique unit identifier).
* Manufacturer Information: Hayward Pool Products, located at 620 Division Street, Elizabeth, New Jersey, 07207.
* Certifications:
* NSF Listed: Meets standards set by the National Sanitation Foundation for swimming pool and spa equipment.
* CSA Certified (ENG. 3): Meets electrical and safety standards established by the Canadian Standards Association.
II. Detailed Motor and Electrical Characteristics
The pump utilizes a robust, high-performance motor designed for reliability in demanding environments.
* Motor Rating: Single-speed, Max-Rated motor (not a full-rated or efficient dual-speed model).
* Rated Output Horsepower (HP): 1.0\text{ HP}.
* Service Factor (SF): 1.25.
* Total Horsepower (THP): The maximum mechanical output is calculated as 1.0\text{ HP} \times 1.25\text{ SF} = 1.25\text{ THP}.
* Power Supply: Designed for single-phase operation at 60\text{ Hz}.
* Voltage Flexibility: The motor can be wired for high or low voltage operation: 115\text{ V} or 208-230\text{ V}.
* Operating Amperage:
* 13.3\text{ Amps} on 115\text{ V} power.
* 6.8\text{ Amps} on 208\text{ V} power.
* 6.5\text{ Amps} on 230\text{ V} power.
* Enclosure Type: ODP (Open Drip Proof), meaning the motor is open to air circulation while designed to prevent dripping liquids from entering critical electrical parts.
* Thermal Protection: Equipped with an internal Auto Protector mechanism to shut off the motor if temperatures exceed safe limits, preventing burnout.
* Insulation: Class B insulation rating.
* Ambient Temperature Rating: Maximum safe operating temperature for the surrounding environment is specified at 50^{\circ}\text{C} (122^{\circ}\text{F}).
III. Construction, Hydraulics, and Convenience Features
The pump's wet-end incorporates several features for improved performance and ease of use.
* Hydraulic Design: Features advanced hydraulics which are credited with improving overall efficiency and ensuring superior priming ability compared to older designs.
* Self-Priming: The pump has excellent suction lift capabilities, capable of priming itself from a suction lift of up to 8\text{ feet} above the water level.
* Plumbing Connections: Standard 1\frac{1}{2}\text{ inch} \times 2\text{ inch} union connections are included on all models, providing flexibility and speeding up installation.
* Strainer Pot Capacity: Includes an extra leaf-holding capacity basket, which minimizes the frequency of maintenance required by extending the time between cleanings.
* Strainer Cover: The lid is clear, allowing visual monitoring of debris levels, and features a secure, user-friendly Tri-Lock Cam and Ramp design that seals tightly with less than a quarter turn.
* Durability: The pump is constructed with rugged materials and is rated to be pressure testable up to a maximum of 50\text{ psi}.
* Retrofit Compatibility: The physical dimensions and plumbing alignment are specifically engineered to seamlessly retrofit with the entire family of Hayward Max-Flo pumps, simplifying replacement in existing installations.
* Ease of Maintenance: The motor assembly is secured with only 4 bolts for quick and straightforward access to the wet end components like the shaft seal and impeller.
IV. Mandatory Safety and Installation Requirements
* WARNING: Electric Hazard: It is critical to disconnect power at the circuit breaker or fuse box before performing any service or maintenance to prevent electric shock, fire, or serious injury.
* Grounding: The motor must be permanently and properly grounded using solid electrical wiring connected to the appropriate terminal block within the conduit box.
* GFCI Protection: A Ground Fault Circuit Interrupter (GFCI) must be installed in the branch circuit supplying power to the pump as a critical safety measure.
* Wiring Material: All electrical wiring must utilize copper conductors only.
* Qualified Personnel: Installation and servicing must be performed by a qualified service professional and must comply fully with all prevailing national, state, and local electrical and plumbing codes.
* Operation Constraint: Never operate the pump without water (DO NOT RUN DRY), as this will cause immediate and irreversible damage to the mechanical seal and potentially the motor bearings.
* Safety Precaution: Keep hands and foreign objects clear of all pump openings while the unit is connected to power.
