MAINTENANCE AND CHEMICALS
Water Sanitation
The spa owner must regularly check and keep the spa water sanitized with scheduled maintenance (daily, if
necessary). Adding sanitizer and other chemical will control bacteria and viruses present in the spa water.
The maintenance of a proper water balance through appropriate use of sanitizers is the single most important
factor in maximizing the life and appearance of the spa tub as well as ensuring clean, healthy and safe water.
Proper technique is important for water testing and treating the spa water. See your pool/spa professional for
chemical, sanitizer, test kits and testing procedures questions.
CAUTION:
ALWAYS FOLLOW THE CHEMICAL MANUFACTURER’S DIRECTIONS, AND THE HEALTH AND
HAZARD WARNINGS.
Do not add chemicals if the spa is occupied. This can cause skin or eye irritation.
Concentrated chlorine
solutions can damage the spa tub. In no event is Intex Recreation Corp., Intex Development Co. Ltd., their
related companies, authorized agents and service centers, retailers or employees liable to the buyer or any
other party for costs associated with the loss of spa water, chemicals or water damage.
WARNING
Always unplug this product from the electrical outlet before removing, cleaning, servicing or
making any adjustment to the product.

Free chlorine:
is the chlorine residual present in the spa water.
Result if too low – Inadequate level of disinfection.
Result if too high – cause odor problem, skin & eye irritation, corroded metals and other materials.
pH:
a value that indicates how acidic or basic the spa water is.
Result if too low – Corroded metals, eye & skin irritation, and destruction of total alkalinity.
Result if too high – Scale formation, cloudy water, shorter

ciency.
Total Alkalinity (TA):
indicates the degree of the water’s resistance to pH change. It determines the speed
and ease of pH change, so always adjust total alkalinity before adjusting the pH level.
Result if too low – Corroded metals, eye & skin irritation. Low alkalinity will cause the pH to be unstable.
Result if too high – Scale formation, cloudy water, shorter
fi
lter/heater runs, eye & skin irritation, high chlorine
demand.
