Filter Maintenance - Cal Spas Pneumatic Series Owner's Manual

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 minerals, dirt and debris, water flow is lessened and jet performance is reduced. This can cause your spa to
not to run or heat properly.
Clean Your Filter Regularly and Replace as Needed.
