Filters and Filtration:
Exclusive Bio-Clean Filter Cartridge:
The average filter cartridge is designed to remove dirt, sand, minerals, phosphates, bather waste and other solids from the spa.
Unfortunately, some spa owners fail to include filter 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 filter cartridge on the market today. What does this mean to you?
Having a filter cartridge that prevents bacteria growth is simply added protection for those times you forget to clean the filter. We recom-
mend that you only replace your spas filter cartridge with a Bio-Clean filter cartridge for ensured protection and peace of mind.
Why do I need to Clean the Filter Cartridge?
Even though the Bio-Clean filter can protect itself from bacterial growth, it still needs to be cleaned on a regular basis to maximize your
spas performance and ensure that heating and filtration systems are functioning correctly. Most filter canisters are manufactured with a
bypass. When a filter becomes full of debris, the bypass will open allowing water to flow around rather than through the filter. When
this happens, your daily filtration cycles are no longer effective. Another casualty of a dirty filter cartridge, is the loss of water tempera-
ture. The spas heating system will only function with the proper amount of water flow through the system. An overloaded filter, can
cause the heating system to become inoperable.
Cleaning the Filter Cartridge:
In addition to spraying the filter with a high pressure nozzle, deep cleaning the filter cartridge is also necessary. Even if the filter car-
tridge may appear clean, you will still need to deep clean it regularly. Minerals and other contaminates are very difficult to see and can
get lodged deep into the filter fibers causing water flow issues.
You will need to have an extra filter cartridge on hand for the deep cleaning process. It is necessary to always have one filter either
cleaning or drying, and the other installed in the spa. This process will double the filter cartridges overall life and performance.
Filter Cleaning:
1. Place the dirty filter into a bucket with 8 oz. of Liquid
Filter Cartridge Clean.
2. Soak for a minimum of 24 hours.
3. Remove filter and spray clean with a water hose, and
allow the filter to dry thoroughly. (Drying time should be
a minimum of two days prior to reinstalling.)
4. Reinstall as described in the Clear Water plan.
Filtration:
Filtration is one of the most important steps you can take ensuring clean, clear water. Regardless of what some people may think, it is far
more inexpensive to fix water clarity problems by filtering your spa than it is to use excessive amounts of chemicals, filtration times,
and/or 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 contaminates during filtration cycles.
Filtration also ensures that chemicals are mixed thoroughly through the water, increasing performance.
Filtration Cycles:
All electronically controlled spas run two filter cycles every day, one every twelve hours. Either the low speed of a two speed pump or
separate filter pump will perform the filtration function. We strongly recommend that you set your spas filtration time to the "F4" setting.
(See the "Setting Filtration Cycles" section in the owner's manual.) This will allow the spa to filter for four (4) hours every twelve hours.
If it seems like a lot, just remember the pool analogy.
