WATER 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 or 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 most important factor in
maximizing the life and appearance of the spa as well as ensuring clean, healthy and safe water.
Proper technique is important for water testing and treating the spa water. See your spa professional for
chemical, sanitizer, test kit and testing procedures questions.
IMPORTANT: The following conditions will lead to slow water heating
● The ambient temperature is lower than 10°C(50°F)
● Outdoor wind speed is above 3.5-5.4m/s(8-12mph)
● The air bubble function is activated when heater is on
● The spa is not properly covered with the spa cover when the heater is on
Water Treatment:
● Always follow the chemical manufacturer’s direction, and the health and hazard warning.
● Never mix chemicals together. Add the chemicals to the spa water separately. Thoroughly dissolve each
chemical before adding one to the water.
● Please note that chlorine and bromine products should never be mixed. This is extremely dangerous. If you
usually use chlorine-based products and you want to switch to bromine-based products, or vice versa, it is
mandatory to completely change the spa water before any product changes.
● Do not add chemicals if the spa is occupied. This can cause skin or eye irritation.
● Do not over use the chemicals, or use concentrated Chlorine. This can damage the spa tub and cause
potential hazard to your skin. Improper chemical use will void the warranty.
NOTE:
● Low pH will damage the spa tub and pump. Damage resulting from the chemical imbalance will void the
warranty.
● High pH (hard water) will result in white coagulations inside the filter pump; which may lead to pump
damage.
