Calcium Hardness Adjustment
Use the included test strips to check the water hardness level and adjust it following below chart.
Lowering Calcium Hardness
If your household water supply is treated with a softener, mix the spa hard water with
the soft water according to the water volume ratio chart to lower the calcium hardness:

Raising Calcium Hardness
If the calcium hardness level in the spa water is lower than 100 ppm, add calcium
chloride into the spa water.

WARNING
Muriatic acid is a caustic chemical and liquid solution of sodium bisulfate (NaHSO
4
) is highly acidic.
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.
Maintenance of Spa Water and Cartridge
Protect all the spa occupants from possible water-related illnesses by
keeping the spa water clean and sanitized. Always practice good hygiene.
To ensure proper spa water quality follow these procedures:
1.
Inspect and clean the filter cartridge once a week, and change the filter cartridge as
needed.
a.
Unscrew the cartridge housing assembly from the spa tub wall and remove the
cartridge
(see drawing 11).

b.
Use a garden hose to rinse off
the cartridge. If the cartridge
remains soiled and discolored
it should be replaced. Keep
spare
cartridges on hand.
C. Reinstall the clean cartridge back into the cartridge housing and replace the
