ATTENTION: IF YOUR SPA IS INSTALLED IN A CLOSED ENVIRONMENT, IT IS
VERY IMPORTANT THAT THE ROOM IS WELL VENTILATED.
IMPORTANT "SUPER CHLORINATION/NON-CHLORINE SHOCK TREATMENT"
NOTE:
After administering a super chlorination treatment or non-chlorine shock to your spa,
leave the cover open for a minimum of 20 minutes to allow the oxidizer gas to vent.
A high concentration of trapped oxidizer gas which may exist as a result of the shock
treatment (not daily sanitation) may eventually cause discoloration or vinyl degradation
to the bottom of the cover. This type of damage is considered chemical abuse and is
not covered under the terms of the limited warranty.
THE SPA WATER MAINTENANCE PROGRAM
Each step in your water maintenance program is dependent on the completion of the
previous steps. Omitting a step or failing to reach the recommended range may cause
an imbalance in your water's chemistry. Unbalanced water chemistry can damage the
spa and its components, as well as cause discomfort for the user.
BALANCING THE TOTAL ALKALINITY (TA)
A. The recommended Total Alkalinity (TA) for your spa water is 125-150 ppm.
B. Total Alkalinity is a measure of the total levels of carbonates, bicarbonates, hydroxides,
and other alkaline substances in the water. TA is referred to as the water's "pH buffer".
In other words, it's a measure of the ability of the water to resist changes in pH level.
C. If the TA is too low, the pH level will fluctuate widely from high to low. Fluctuations in
pH can cause corrosion or scaling of the spa components. Low TA can be corrected
by adding sodium hydrogen carbonate (pH/Alkalinity Up).
D. If the Total Alkalinity is too high, the pH level will tend to be high and may be difficult
to bring down. It can be lowered by using sodium bisulfate (pH/Alkalinity Down).
E. Once the TA is balanced, it normally remains stable, although the addition of more
water with a high or low alkalinity will raise or lower the TA reading of the water. F.
When the Total Alkalinity is within the recommended range, proceed to the next step.
BALANCING THE CALCIUM HARDNESS (CH)
A. The recommended Calcium Hardness (CH) level for your spa is 150-200 ppm.
B. Calcium Hardness is a measure of the total amount of dissolved calcium in the water.
Calcium helps control the corrosive nature of the spa's water. That's why calcium-low
water (commonly known as "soft" water) is not recommended. It is very corrosive to
the equipment, and can cause staining of the spa shell.
C. If the CH is too high (commonly known as "hard water"), formation of scale on the
spa's shell surface and equipment can result. CH can be decreased by dilution–a
mixture of 75% hard and 25% soft water will usually yield a reading within the correct
range. If soft water is not available or practical for you, a stain and scale inhibitor
should be added to the spa water, according to label instructions.
D. If the CH is too low add CH Increaser.
E. Once the CH is balanced, it normally remains stable, although the addition of more
