Filter Maintenance

FILTER MAINTENANCE
Portable Spas:
Filtration starts on electronically-controlled spas as soon as the pumps are primed and water flow is steady. As
the flow of water goes through the filter, dirt and debris is removed and accumulated in the filter cartridge. As
the filter cartridge accumulates dirt and debris, water flow is restricted and jet production is reduced. This can
cause your spa to not run or heat effectively.
Clean your filter regularly and replace as needed.

Filter Cleaning:

Your new Cal Spa has been designed for quick and easy filter maintenance. The filter cartridge should be
cleaned once a week.
1. Turn the power off at the breaker.
2. Remove the filter(s) cover - if applicable.
3. Remove the filter(s) basket (align the flat areas on the filter basket and the canister).
4. Remove the filter(s) by pulling up and out.
5. Clean the filter with a garden hose.
A. Hold the filter vertically.
B. Spray the filter cartridges with a pressure nozzle, starting from the top and spraying down each
pleat.
C. Turn the filter cartridge over and repeat Step 5B.
D. Reinstall the filter cartridge in reverse order of removal.
6. Deep clean filter cartridge(s) every month. Use only a Cal Spa-approved filter-cleaning chemical.
