gets. A low pH will be corrosive to metals in the hot tub equip-
ment. A high pH will cause minerals to deposit on the interior
surface (scaling). In addition, the ability of the sanitation agents
to keep the hot tub clean is severely affected as the pH moves
beyond the ideal range. That is why almost all hot tub water test
kits contain a measure for pH as well as sanitizer.
Sanitizer (Chlorine or Bromine): To destroy bacteria and
organic compounds in the hot tub water by breaking them down
into non-harmful levels which get filtered out. A sanitizer must be
used regularly, either chlorine or bromine. Sanitizing your spa
water is the most important spa maintenance you can do for
yourself.
Total Alkalinity: This refers to the ability of the hot tub water
to resist changes in pH. Controlling alkalinity can help keep your
pH in the appropriate range thereby lessening the need for pH
balancing. If the TA is too low the pH level will fluctuate rapidly
from high to low. If the TA is too high the pH will tend to be too
high and will be very difficult to bring back down.
Calcium Hardness: This is a measurement of dissolved cal-
cium in the water. Calcium will help control the corrosive nature
of the spa’s
water.
WARNING: Never store chemicals inside the equipment
area of your spa.
IMPORTANT:
Do not use Hydrogen Peroxide based sanitiz-
ers in your spa. When using Chlorine or Bromine tablets you
must use a floating dispenser. These chemicals can have an
extremely
corrosive effect on certain materials in the spa. Damage caused
by use of these chemicals, or improper use of any chemicals, is
not covered under the spa’s warranty.
OTHER ADDITIVES:
Many other additives are available for
your spa. Some are necessary to compensate for out-of-balance
water, some aid in cosmetic water treatment and others simply
alter the feel or smell of the water. Your Authorized Dealer can
advise you on the use of these additives.
MICROSILK
If your hot tub is equipped with a MicroSilk generator you can
take advantage of some incredible health and appearance bene-
fits. Find expanded information below on the Microsilk system,
benefits and operation.
ABOUT MICROSILK
MicroSilk produces a silky white cloud of micro bubbles that are
small enough to enter the pores of your skin. When the micro
bubbles enter the pores of your skin they absorb foreign con-
taminants and release oxygen. This process improves collagen
production, leaving skin feeling smooth and healthy. Using the
OWNER’S MANUAL
2020
MicroSilk System on a regular basis greatly reduces the appear-
ance of wrinkles and your skin will appear younger and firmer
after only a short period of time.
TREATING SKIN CONDITIONS
MicroSilk is used to treat various skin conditions including: Ecze-
ma, Psoriasis, Ichthyosis and aids in reducing scar tissue. More
information is available from your local dealership.
OPERATION
MicroSilk is produced by a unique piece of equipment, the Mi-
croSilk Generator , that roughly resembles a jet pump and is lo-
cated in your equipment area. The MicroSilk generator is pow-
ered by your hot tub and controlled using your main control pan-
el.
The MicroSilk Generator requires both water and air to function.
Water is supplied from the water in your hot tub and an inde-
pendent air line connects from a small grate-like fitting from
above your spas’ waterline –providing the oxygen needed for
MicroSilk production.
There is an adjustment valve along the water supply line to the
MicroSilk generator that varies the air/water ratio that enters into
the system. This adjustment is extremely sensitive and turning
the adjustment valve only 1 mm can greatly effect the level of
MicroSilk production. When your spa leaves the factory, it has
been tested and the valve position marked for optimum MicroSilk
production.
Once activated, you will be able to see a white cloud of silky wa-
ter coming from the specialized fitting in your spa. Depending on
the size of your hot tub you should see your entire spa filled with
oxygen rich micro bubbles within minutes (more water capacity
equals a longer duration until the entire hot tub fills with white
silky water).
TROUBLESHOOTING
If your spas’ MicroSilk production seems slow, or lower than nor-
mal:

Ensure that the air supply line is clear of any debris.

Verify that water is flowing to the MicroSilk generator.

Check the air/water mixture valve. Return to factory settings
by aligning factory placed marks.
To adjust: make incremen-
tal (1 mm) turns and wait at least 90 seconds before making
further adjustments.

Shut power off at breaker and make sure all electrical, water
and air lines have a good connection to the MicroSilk Genera-
tor.
