Maintenance
Water Chemistry
Water chemistry is critical in a spa system.
Chemicals are used to sanitize the water and control
the pH balance. The combination of high water
temperature and small water volume means that the
chemical balance must be watched carefully. It is
recommended that you purchase a chemical start up
kit, and the additional chemicals needed to maintain
the proper/optimum chemical balance, from your
dealer.
Sanitizing
Sanitizing the water destroys harmful organisms
and keeps your spa healthy and safe. Three commonly
used spa sanitizers or oxidizing agents are bromine,
chlorine and ozone. Chlorine or bromine are chemicals
that you add to the water. Ozone is a gas that is
produced by an ozonator and injected into the water. It
is important that a residual of sanitizer remain in your
water. High water temperature, aeration and use will
increase the need for sanitizer.
In addition to maintaining a residual, it is important to
“shock” your spa water periodically and after heavy
use. This addition of substantial amounts of sanitizer
super-chlorinates the water and oxidizes non-filterable
organic residue. Allow the sanitizer level to drop back
to the residual amount before using. Also use your
Clean Up Cycle (See pgs. 15 and 19) after heavy use
for additional filtration.
Tests should be done daily with your test kit to
keep a chlorine or bromine residual of 3.0 to 5.0 ppm.
pH Level
pH is the balance of acidity and alkalinity in the
water. Maintaining proper pH is important for the
effectiveness of your sanitizer, for user comfort, and to
prevent corrosion of the spa equipment.
Caution: Never mix two chemicals together.
Caution: Never store chemicals in the equipment
compartment.
Caution: Do not use muriatic acid to balance pH as
it will damage your spa surface and equipment.
Recommended Levels
pH: 7.2–7.6 (Ideal 7.4–7.6)
Sanitizer Residual: 3.5–5.0 ppm
Total Dissolved Solids: 100–200 ppm
Free Available Sanitizer: 3.0–5.0 ppm
Total Alkalinity: 80–100 ppm ideal for
dichlor, trichlor, and
bromine.
Note: Make sure you use fresh test kit
strips/chemicals. Test kits and test chemicals should
be stored in a cool, dry location. Check the
manufacturer’s instructions to determine shelf life and
expiration date.
Water Maintenance With the
CleanZone™ Water Treatment System
Equipping your spa with a MAAX spas® Clean
Zone™ system that includes the Powerworks™
Ozonator is a smart decision. CleanZone™ treats the
water in your spa with a specialized ozone application.
The use of ozone in conjunction with spa sanitizing
and water balancing chemicals provides you with a
cleaner, healthier spa, reduces chemical usage, and
protects your skin from chemically induced irritation.
Sanitizing With Ozone
Spas vary in size, and frequency and conditions
of use. For this reason you will need to establish your
sanitizing program based upon your own personal use.
When using ozone, you should start by balancing your
water chemistry as you normally would. A spa should
run and be ozonated a minimum of six hours per day.
If your spa is heavily used, this run time should be
increased. Your spa produces ozone during the
filtration cycles (Pgs. 16 and 20).
The amount of a residual sanitizer (chlorine or
bromine) that you maintain in the water will also vary
depending on use. It is recommended that you
maintain a residual of 3.0–5.0 ppm. Periodically, and
after periods of heavy use, it is necessary to “shock”
your spa with large amounts of sanitizer.
Note: Extra filtration can be provided by
manually starting a clean-up cycle. Turn Pump 1 on in
low speed. The pump will operate for 4 hours and
then automatically turn off. The heater will also
operate during this period if the controls are set in
Standard mode.
Specialty Chemicals
While ozone may significantly reduce the usage
of specialty chemicals (chlorine and bromine), it is not
a substitute for these chemicals. All chemicals should
continue to be monitored, especially during periods of
heavy usage and when changing or replenishing the
spa water.
