Installation Guide
Proper installation of your new filter cartridges is crucial for effective water filtration. Always ensure your hot tub is powered off before beginning any maintenance.
- Power Off Hot Tub: Locate the main power switch for your hot tub and turn it off. This prevents accidental operation and ensures safety during filter replacement.
- Locate Filter Compartment: Identify the filter compartment, typically accessible from the top or side of the hot tub. Refer to your specific hot tub model's manual for exact location and access instructions.
- Remove Old Filters: Carefully unscrew or unlatch the old filter cartridges. They may be held in place by a central standpipe or a locking mechanism. Remove any debris or large particles from the compartment.
- Clean Filter Compartment: Wipe down the inside of the filter compartment to remove any accumulated grime or residue.
- Insert New Filters: Place the new Hot Spring filter cartridges into the compartment. Ensure they are seated correctly and securely. If applicable, screw them onto the standpipe or engage the locking mechanism until snug. Do not overtighten.
- Restore Power: Once all new filters are installed, close the filter compartment cover and restore power to your hot tub.
- Bleed Air (if necessary): After refilling or restarting, some air may be trapped in the system. Run the jets on high for a few minutes to purge any air from the plumbing.

Operating Principles
These filter cartridges are integral to your hot tub's water circulation and purification system. Water is drawn from the hot tub, passed through the pleated filter material, and then returned to the tub. The pleats provide a large surface area to effectively capture suspended particles, debris, and contaminants, ensuring clean and clear water for bathing.
The filters work continuously with your hot tub's pump to maintain water quality. Regular replacement ensures the system operates efficiently and prolongs the life of other hot tub components.
Maintenance and Replacement
While some hot tub filters can be cleaned, these particular filters are designed for replacement to ensure optimal filtration performance. The frequency of replacement depends on hot tub usage, bather load, and water chemistry.
- Regular Inspection: Periodically inspect your filters for visible signs of wear, tearing, or excessive clogging that cannot be rinsed off.
- Replacement Schedule: It is generally recommended to replace hot tub filters every 12-18 months, or more frequently if the hot tub is heavily used or if water quality issues persist despite proper chemical balance. Refer to your hot tub manufacturer's guidelines for specific recommendations.
- Signs of Clogged Filters: Indicators that your filters may need replacement include reduced water flow from jets, cloudy water that doesn't clear with chemicals, or the hot tub pump working harder than usual.
Follow the "Installation Guide" steps in reverse to remove old filters and then proceed with the installation of new ones.
Troubleshooting Common Issues
Issues related to filtration often manifest as water quality problems or reduced system performance. Here are some common issues and their potential filter-related causes:
- Cloudy Water: If water remains cloudy despite balanced chemistry, the filters may be saturated with fine particles or have reached the end of their effective life. Action: Inspect filters for excessive dirt; if heavily soiled or old, replace them.
- Reduced Jet Pressure/Flow: A noticeable decrease in water flow from the jets can indicate clogged filters restricting water circulation. Action: Check filters for blockages; replace if severely clogged.
- Pump Overheating/Noisy Operation: A pump working harder than usual or making unusual noises can be a sign of restricted water flow due to dirty or old filters. Action: Turn off hot tub, inspect and replace filters if necessary.
- Persistent Foam: While often related to water chemistry, excessive foam can sometimes be exacerbated by filters that are not effectively removing organic contaminants. Action: Ensure filters are clean and replaced regularly.
Always ensure proper water chemistry is maintained in conjunction with effective filtration for optimal hot tub performance.
