Cleaning and Replacing the
Filter
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
x water clarity problems by ltering your spa than
by using excessive amounts of chemicals, excessive
ltration times, or by water replacement.
Cal Spas™ ltration system draws contaminated water
through the exclusive Bio-Clean™ lter removing debris
from the water. It then pumps the newly cleaned water
back into the spa through various jets. Spas equipped
with the optional ozonator will also receive ozone
injection into the ltered water for further protection
against contaminants during ltration 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 ow is
steady. As the ow of water goes through the lter, dirt
and debris is removed and accumulated in the lter
cartridge. As the lter cartridge accumulates dirt and
debris, water ow is restricted and jet performance is
reduced. This can cause your spa to not run or heat
effectively.
Clean your lter regularly and replace as needed.
Filter Cleaning
Your new Cal Spa has been designed for quick and
easy lter maintenance. The lter cartridge should be
cleaned once a week. These instructions apply to both
dual and single ltration systems.
Turn the power off at the breaker.1.
Remove the lter by turning it counterclockwise 2.
and unscrewing the bottom threads. Then pull it
up and out.
Clean the lter with a garden hose as follows:3.
Hold the lter vertically.a.
Spray the lter cartridges with a pressure b.
nozzle, starting from the top and spraying
down each pleat.
Turn the lter cartridge over and repeat Step c.
3b.
Deep clean lter cartridge every month.d.
Exclusive Bio-Clean™ Filter Cartridge
The lter cartridge is designed to remove dirt, sand,
minerals, phosphates, bather waste and other solids
from the spa. Unfortunately, some spa owners fail
to include lter cleaning as part of their chemical
maintenance plan. Filters accumulate debris and
become prime areas for bacteria growth.
The Cal Spas™ exclusive Bio-Clean™ Filter is the
only antibacterial lter cartridge on the market today.
Having a lter cartridge that prevents bacteria growth
is added protection for those times you forget to clean
the lter. We recommend that you only replace your
spa’s lter cartridge with a Bio-Clean™ lter cartridge
for ensured protection and peace of mind.
