SPA WATER CHEMISTRY AND BALANCE (continued)
SPA Water Adjustment
How to adjust the spa water chemistry when the levels are off the range.
CAUTION:
Always follow the chemical manufacturer’s directions, and the health and hazard warnings.
Total Alkalinity (TA) Adjustment
Remove the spa cover to aerate the water and use the included test strips to check the chemistry level.
Ensure the chlorine level in the water is between 2-4 ppm fi rst, as chlorine will aff ect the TA test result.
If the TA level (and not the pH) is higher than 120 ppm, add appropriate chemical product to lower the TA
level.
If the TA level is lower than 60 ppm, add appropriate chemical product to raise the TA level.
NOTE:
After adjustment, retest the water after 24 hours and adjust again if necessary.
pH Adjustment
After the total alkalinity has been lowered to 120 ppm or raised to 80 ppm and the pH is still high or low, add
appropriate chemical product to adjust the pH level between 6.8 and 7.6.
Calcium Hardness Adjustment
Use the included test strips to check the water hardness level and adjust it with appropriate chemical
product.
WARNING
Handle all chemicals with care and wear extra personnel protective equipment
including goggle and gloves. It is very important not to splash acid onto your skin
or clothing, or into your eyes.
1) Always keep the spa cover on to minimize heat loss during heating of the spa between
uses (but not while it is being used). Ensure the cover is fi tted tightly, as per manufacturer’s
instructions to maximize insulation. It shall be recommended that the cover, when not in
use, should be kept off the ground to retain its cleanliness (particularly the surface in close
proximity to the water spa water surface). The cover should be stored in an appropriate
location, where it cannot be damaged, or cause damage.
2) Check the set water temperature and consider lowering it for the times when the spa will
typically not be in use.
3) Depending on external conditions, consider turning off the heater entirely if not using the spa
for an extended period of time (where the spa provides this option, but still maintains residual
disinfection/pH-values).
4) Consider that the comfortable temperature range during use may be lower than the maximum
safe temperature.
5) Use the included insulating ground cloth underneath the spa to minimize heat loss through
the bottom of the spa.
6) Maintain clean fi lters to preserve appropriate working conditions for the pump and avoid
unnecessary water replacement and re-heating.
