Keep in mind that the filter cartridge must be replaced every 3-6 months for a new one.
If it is damaged or clogged, even sooner. In this case, it can no longer be used. Make-up,
sunscreens and other body products have a nega�ve effect on the water quality and
reduce the life of the cartridge
WARNING: Always add chemistry to the water, never the other way around!
Do not add chemistry to the water, when there are people in it.
For ideal mixing of the chemical, use pumps!
Store the chemical according to the instruc�ons on its label!
Test the water regularly, depending on the use of the Hot Tub Wave (ideally once a
week) with the appropriate water quality tester.
According to the measured pH value, adjust the water with the appropriate chemical
treatment (recommended HANSCRAFT SPA - pH PLUS and pH MINUS).
d) According to the measured Cl (chlorine) level, adjust the water with the appropriate
chemical (recommended HANSCRAFT SPA - MULTI MINI tablets 3 in 1), follow the
instruc�ons on the product label.
For chlorine to work properly, the pH value must first be adjusted.
e) We recommend cleaning/replacing the cartridge filter before using the chemistry.
Chlorine shock
- in case of heavy pollu�on, the water must be treated with a dose quickly
dissolved chlorine to give a chlorine shock. Before that, it is necessary to measure and
adjust the pH level of the water in the Hot Tub Wave to 7.0-7.6 and then control the chlori-
ne concentra�on in the water. Once a week or a�er adding more water, add the shock
dose of 10 -20 g/m³ (2 tablespoons). Carry out this treatment as usual without people
present in the Hot Tub Wave. A�er applica�on, turn on the pumps for a few minutes to
allow the chemistry to to mix well with the water. If using granules, dissolve them before
use in a small amount of water. Before using the Hot Tub Wave let to decrease the chlorine
level to 3 mg/l.
Oxygen shock -
in case of heavy pollu�on, the water must be treated with a dose quickly
dissolved oxygen to give an oxygen shock. Before that, it is necessary to measure and
adjust the pH level of the water in the Hot Tub Wave to 7.0-7.6 and then control the oxy-
gen concentra�on in the water. Add oxygen (2tablets) once a week or when more water is
added. Make this adjustment as usual without people present in
the Hot Tub Wave.
A�er applica�on, turn on the pumps for a few minutes to allow the chemistry
to mix well with the water. Allow the oxygen level to drop to 15 mg/l before using the
Hot Tub Wave.
