Filtration
Filtration is one of the most important steps you can take to ensure clean, clear water. Regardless of what some
people may think, it is far less expensive to fix water clarity problems by filtering your spa than by using
excessive amounts of chemicals, excessive filtration times, or by water replacement.
Cal Spas™ filtration system simply draws contaminated water through the exclusive Bio-Clean™ filter
removing debris from the water. It then pumps the newly cleaned water back into the spa through various jets.
Spas equipped with the optional Quest 2000 Ozonator will also receive ozone injection into the filtered water
for further protection against contaminants during filtration cycles. Filtration also ensures that chemicals are
mixed thoroughly through the water, increasing performance.
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 performance 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. These instructions apply to both dual and single filtration systems (Figure 19).
