Overview

1. Function Description
2. Usage Features
3. Maintenance Features

The Hayward MaxFlo VS is a variable speed pump specifically designed for in-ground and above-ground swimming pools and spas. It is engineered to meet the demanding requirements of systems equipped with large capacity filters, heaters, and pool cleaning equipment. The pump features a totally enclosed permanent magnet motor and an advanced hydraulic design, which together provide unparalleled energy savings.

Function Description

The primary function of the MaxFlo VS pump is to circulate water through the pool or spa system. This circulation is essential for filtration, heating, and the operation of various pool accessories and cleaning equipment. The variable speed capability allows users to adjust the pump's RPM (revolutions per minute) to match specific operational needs, leading to significant energy savings compared to single-speed pumps.

The pump's operation is managed through a user-friendly interface equipped with a membrane keyboard and a digital display. This interface allows users to select from preset speeds (V1, V2, V3) or customize speeds and run times.

• Priming Mode: The pump is factory set to start in a prime mode, typically running at 3000 RPM for a set duration (default 2 minutes, adjustable from 0 to 4 minutes). This ensures the pump is filled with water and air is expelled from the system before normal operation begins. If the prime mode is set to zero, it is disabled, and the pump starts directly at speed V3.
• Preset Speeds (V1, V2, V3): These buttons allow the pump to run at predetermined speeds for specific lengths of time.
  • V1 (Low Speed): Default 1450 RPM. This speed is designed for daily filtration requirements for most private use pools up to 50,000 liters. It aims to turnover the entire pool volume in an average operation time of 8 to 10 hours, offering significant electricity and money savings. Running at lower speeds also improves filtration by allowing the filter to remove smaller particles more effectively and contributes to quieter operation.
  • V2 (Med Speed / Boost): Default 2400 RPM, with a default run time of 4 hours (adjustable from 5 minutes to 18 hours). This speed is suitable for operating automatic pool cleaners, increasing flow for pool accessories, or during periods of heavy bather load.
  • V3 (High Speed / Turbo): Default 3000 RPM, with a default run time of 5 minutes (adjustable from 5 minutes to 18 hours). This speed is used for demanding functions like backwashing the filter or operating accessories that require extra flow, such as spa jets and water features.
• Configuration Menu: Users can access a configuration menu to customize various parameters, including:
  • Prime Mode run time (0-4 minutes).
  • V1 Speed (600-3000 RPM).
  • V2 Speed (600-3000 RPM) and V2 Timer (5 minutes-18 hours).
  • V3 Speed (600-3000 RPM) and V3 Timer (5 minutes-18 hours). These settings allow for precise tailoring of the pump's operation to the specific needs of the pool or spa.
• Automatic Overload Protection: The motor is equipped with automatic thermal overload protection, which shuts off the motor before heat damage can occur due to abnormal operating conditions. The motor will automatically restart once a safe heat level is reached.
• Automatic Restart: In the event of an overload, overheating, or power failure, the pump controller will automatically attempt to restart the pump.

Usage Features

The MaxFlo VS pump offers several features that enhance its usability and efficiency:

• Energy Efficiency: The variable speed motor allows for significant energy savings. By reducing the pump speed, power consumption can be dramatically lowered (up to 75% reduction for a 50% speed decrease). The motor interface displays real-time power consumption in Watts, enabling users to easily calculate operating costs.
• Quiet Operation: Running the pump at lower speeds results in quieter operation, making it less intrusive to neighbors and enhancing the overall pool experience.
• Improved Filtration: Slower water movement through the filter allows for better removal of smaller particles, leading to cleaner pool water.
• Reduced Equipment Stress: Operating at lower speeds reduces the total dynamic head, which in turn places less stress on other pool equipment (like the filter), potentially extending their lifespan.
• Flexible Installation: The pump is designed for pools of all types and sizes, featuring 40mm or 50mm union connection tails to accommodate a variety of plumbing configurations. It can be used for both new construction and as a replacement pump on existing pools and spas.
• Cam and Ramp Strainer Cover: This design allows the strainer cover to seal with less than a quarter turn, simplifying access for basket cleaning.
• User Interface with Digital Display: The five 7-segment digits on the display provide clear information about the pump's status, including RPM, remaining run time, and power consumption. The DISP/FUNC button allows users to scroll through these informational screens.
• Quick Speed Change: Users can quickly adjust the current running speed using the up and down arrow buttons. The new speed can be saved by simultaneously pressing both arrow buttons.
• Service Mode: For troubleshooting, the pump can be put into Service Mode, where only the motor RPM can be changed (600-3000 RPM), and no speeds are saved. This allows for testing without interfering with programmed settings.

Maintenance Features

The MaxFlo VS pump is designed with maintenance in mind, incorporating features that simplify upkeep and ensure longevity:

• Easy Strainer Basket Access: The cam and ramp strainer cover allows for quick and easy removal to clean the strainer basket. Regular cleaning of the basket is crucial for maintaining optimal pump performance and preventing obstructions.
• Durable Components: The pump uses high-quality materials, and the strainer cover gasket should be inspected regularly and replaced as needed to ensure a proper seal.
• Self-Lubricating Motor Bearings and Shaft Seals: Hayward pumps are designed with self-lubricating components, eliminating the need for external lubrication.
• Motor Protection: The motor should be kept clean, and air vents and the fan must be free from obstruction to prevent overheating and damage. It is important not to hose off the motor with water.
• Shaft Seal Replacement: While shaft seals are durable, they may eventually require replacement due to wear or damage. The manual provides detailed instructions for replacing the shaft seal assembly using genuine Hayward replacement kits. This process involves carefully handling the rotating and stationary sections of the seal to avoid scratches.
• Gasket and O-Ring Care: Gaskets and o-rings should be inspected for wear or damage and replaced with genuine Hayward parts as necessary. Only silicone-based lubricants should be used on gaskets, o-rings, and plastic components, as petroleum-based lubricants can cause damage.
• Tightening Instructions: The strainer cover lock ring and union nuts should be tightened by hand only, without the use of wrenches, to prevent over-tightening and potential damage.
• Troubleshooting Guide: The manual includes a comprehensive troubleshooting section to help users diagnose and resolve common issues such as the motor not starting, motor cutting out, pump not priming, low flow, or noisy pump operation. It also lists variable speed drive error codes with their indications, aiding in quick problem identification.
