Changing the Default Filtration Setting
3. Filtration
The filter is the part of your spa that removes the debris from the water and needs to be cleaned on a regular basis to
maximize your spa’s filtering performance and heating efficiency.
It is extremely important that you never run the spa without a filter. There is a possibility that debris may
be sucked into the plumbing through the filter well.
We recommend you trying different times and durations for the filter cycles until you find a filtration plan that works for
you.
Cleaning the Filter
In addition to spraying off the filter weekly to remove surface debris, your filter should be deep cleaned periodically to
dissolve scale and particles that get lodged deep within the filter fibers and impede the filtration process. Even if the filter
looks clean, scale and particles can clog the fibers and prevent water from flowing through the filter resulting in the most
common spa problem—no heat, caused by a dirty filter.
We recommend you clean your filter at least once a month, possibly every two weeks depending on how frequently you
use your spa, and replace it once a year or as necessary. See page 31 for instructions on removing and cleaning the filter.
Shocking the Water
In addition to using a chemical sanitizer, you will periodically
need to shock the water. Shocking helps refresh the water
by breaking down organic waste contaminants which
cause odor and cloudy water. After treatment, water
quality and clarity is often completely restored.
The two types of shock are sodium dichlor and potassium
monopersulfate (MPS). You can use either type of shock
regardless of which sanitizer you use. Even if you use
bromine, you can use a chlorinated shock if you wish -- in
fact, you may find a chlorinated shock is more effective
than dichlor or MPS alone.
If irritating chloramines are present, shocking also converts
them back to active chlorine. If you use bromine sanitizer,
shocking activates the bromide ion (which by itself has no
disinfecting capability) which becomes hypobromous acid in
water, a good sanitizer.
Add one ounce of oxidizer shock once a week, after
heavy bather loads, or if water has a strong odor.
Spa must be running with all of the jets on high for 30
minutes with the cover open. If necessary, repeat shock in
30 minute intervals.
