The provided manual describes the HD-4 Black Diamond Filter System, a high-definition filtration system designed for pools. This system combines the benefits of Diatomaceous Earth (DE) filters, known for producing crystal clear water, with the convenience and ease of maintenance associated with cartridge filter systems.
Function Description
The HD-4 Black Diamond Filter System operates under high pressure to filter pool water. It utilizes four easily accessible and removable elements. As water passes through these elements, impurities such as dirt, algae, and even some forms of bacteria are filtered out, resulting in sparkling clear water. The system's design significantly increases the filter's internal surface area, providing a much greater cleaning capacity per cycle without increasing the overall tank size. This efficient flow also contributes to energy savings by reducing the pump's energy consumption. The combination of four Black Diamond elements in a single tank design leads to better performance and longer filter cycles, which means less frequent cleaning and maintenance. The Black Diamond elements are capable of removing even the tiniest contaminants, ensuring crystal clear water for many years.
Important Technical Specifications
While specific numerical technical specifications like flow rate, filter area, or maximum operating pressure are not explicitly detailed in the provided pages, the manual emphasizes several critical operational parameters and warnings:
- Operating Pressure: The filter operates under high pressure. It is explicitly stated that the system should NEVER be subjected to a working pressure over 50 psi, even during tests. The pressure gauge is the primary indicator of system operation and must be kept in good working order.
- Electrical Safety: Installation must be performed by a qualified technician in accordance with all electrical codes. Electrical controls (switches, timers) must be installed at least 5 feet from the filter system. Power to the filter equipment must always be disconnected at the circuit breaker before servicing, and the disconnected circuit should be tagged to prevent accidental connection.
- Plumbing: All plumbing connections must conform to local/state plumbing and sanitary codes. Filter plumbing connections with O-Ring seals require silicone-based lubricant; pipe compound, glue, or pipe dope should NOT be used on bulkhead connections. Piping must be adequately supported.
- Air Relief Valve: The manual air relief valve, located on top of the filter, is crucial for releasing trapped air and relieving pressure before servicing. Its position should allow water to drain away from electrical connections.
- Water System Compatibility: The HD-4 Black Diamond should NOT be connected to a Public Water System.
- Check Valves: A check valve installed ahead of the filter system is recommended to prevent filter contents from draining back into the pool. Another check valve between the filter and heater is advised to prevent hot water from backing up and potentially damaging internal components.
- Pressure Testing: The system should NOT be pressure tested with an air compressor.
Usage Features
The HD-4 Black Diamond Filter System is designed for user convenience and safety, incorporating several usage features:
- Easy Element Access: The system features four easily accessible and removable elements, simplifying the cleaning process.
- Two Cleaning Methods: Users have two convenient options for cleaning the filter:
- Removing and rinsing off the elements.
- Removing the tank lid, opening the drain plug, and simply rinsing the elements in place. The latter is described as the more popular choice.
- Clear Operation Indicators: The pressure gauge serves as the primary indicator of the system's operational status, allowing users to monitor performance.
- Safety Warnings: The manual prominently features warnings about operating under high pressure, the risk of electrical shock/electrocution, and the importance of following instructions precisely to prevent severe injury, death, or property damage. These warnings are integrated into the operational guidelines.
- System Restart Instructions: Detailed steps are provided for safely restarting the system after service, emphasizing the importance of opening the air relief valve, standing clear of the tank, and slowly closing the valve once a steady stream of water appears.
- Troubleshooting Guide: A quick reference troubleshooting section helps users identify and correct common issues such as air entering the filter system, elements liming up, short filter cycles, pressure drops in the gauge, pressure remaining high after backwashing, and dirt/debris continuously entering the pool.
Maintenance Features
Maintenance of the HD-4 Black Diamond system is designed to be straightforward, contributing to its "ease of maintenance" claim:
- Element Cleaning: The core maintenance involves cleaning the four Black Diamond elements. This can be done by spraying water at them with a garden hose (without a nozzle) to dislodge dirt and debris, washing each element both inside and out.
- Tank Cleaning: The inside of the tank body and the manifold should also be washed out to remove any debris.
- O-Ring Lubrication and Inspection: The lid O-Ring and pump's hair and lint strainer O-Ring should be inspected and lubricated with silicone-based lubricant if they appear dry. The tank gasket on the lip of the bottom tank half should be checked for firmness and even placement, with a strict instruction NOT to use petroleum lubricants on this gasket.
- Air Relief Valve Maintenance: The air relief valve should be checked for debris and dirt and cleaned if necessary.
- Clamp Tension Check: The spring coils of the filter clamp must be checked periodically (about once a month) to ensure they continue to touch each other, indicating sufficient tension. If not, the tightening procedure (tapping and tightening until coils touch) must be repeated.
- Part Replacement: Users are advised to maintain the circulation system properly and replace worn out or damaged parts immediately.
- Mineral Deposit Removal: For elements liming up due to mineral deposits (magnesium, calcium), a specific cleaning procedure is provided: soaking the elements in a solution of 6 parts water and 1 part muriatic acid.
- Pre-Service Procedures: Before any service, the pump must be turned off, automatic controls shut off, and the air relief valve opened to relieve pressure. This ensures safety during maintenance tasks.
- Clamp Installation Instructions: Detailed, step-by-step instructions are provided for installing the filter clamp, emphasizing the importance of precise execution to prevent the lid from blowing off, especially during startup or operation. This includes hand tightening, tapping with a mallet, and using a 7/8 inch wrench until the spring coils touch.
