6 Watertreatment

6.1

Preparations

• Speciﬁc rules for water treatment in your residential spa cannot be prescribed. The minimum required standards for spa maintenance are outlined

below. 4SeasonsSpa is not responsible for providing information about water treatment. This page will only provide you with some guidelines.

Each region or country has its own rules about water treatment.

• Take into account the directions given by your dealer. Local dealers are familiar with different water treatment products, speciﬁc to your region and

water-type. Make sure you are properly informed.

• Ensure proper information is provided on the chemicals being offered. Ensure the provided chemicals can be used for the water treatment in your

spa, and that they are allowed in the country you will be using your spa in. Very important: 4SeasonsSpa is not responsible for the water quality

in your spa, as this is entirely dependent on water treatment and the water quality from your supplier.

• To ﬁll your spa, use only regular tap water.

• As soon as the spa is ﬁlled, begin water treatment. The ﬁltration mechanism has to be on continuously, which requires constant current

to be available.

3-step Water treatment

1 Test the pH value of the water and adjust if necessary. Keep the pH between 7.2 and 7.6. At this pH value disinfecting products will work best.

The total alkaline value should be kept between 80 and 120 ppm (mg/l). Record the values in a log-book for your records.

2 Free chlorine should be kept at 3.0–4.0 ppm.

3 Every two or three months, the night before draining the spa, add some special Anti-scale spa chemicals to your spa water and leave it to run

overnight. This will remove any lime scale from your pipes and pumps. The manufacturer is not liable for replacing pumps, heater, jets or other parts,

due to too high calcium levels.

A regular checkup (at least twice a week and before each spa use) of the water is necessary for the following parameters:

a) pH-value between 7.2 and 7.6

b) Free chlorine value must be 3.0–4.0 ppm

c) Bound chlorine should be at most 0.2 mg/l and always lower than Free chlorine

d) Total alkaline value should be between 80 and 120 ppm
