Chemical balance of water
The water in the spa is clean and clear if the chemical components are in equilibrium.
1. pH values:
The first important indicator is the pH value of the water. The pH value is measured on a scale from 0 to 14, where 7 is neutral. Water
below that level is acidic, while water above that level is alkaline. The human eye has a pH of approximately 7.5; water below 7.2 and
above 7.8 will sting the bather’s eyes. Experience shows that most problems are caused by an excessively high pH value. An incorrect
value reduces the effect of the disinfectant.
2. Water hardness:
The hardness of water is determined by the quantity of calcium and magnesium salts dissolved in the water. Hard water has high
levels of these dissolved salts, and deposits will therefore form if nothing is done. Deposits can cause major damage to the walls of
the tub, the pipes, the filter and the heating and technical equipment. Drinking water in Sweden is generally soft. It is not possible to
reduce the hardness of water by adding chemicals, but it is possible to prevent the formation of deposits.
3. Disinfection:
Disinfectants are the chemicals that eliminate or neutralise microorganisms (bacteria, algae, fungi, viruses) in the water. Microorgan-
isms are small (microscopic) organisms that cannot be seen with the naked eye and which enter the water continuously through rain,
the wind and the bodies of bathers. If they are not eliminated, they can be transmitted from one person to another through the water
(and can cause illnesses and infections). Organic substances make the water in the tub cloudy. Usually, chlorine or bromine-based
disinfectants are used as these are hot water tubs.
4. Foam:
Foam is a gathering of small and large bubbles and colloidal impurities on the water surface. It is caused mainly by a mixture of dirt,
cosmetics, body care products, etc., which break off from the skin and are not soluble in water. This adversely affects the appearance
and cleanliness of the water.
5. Water analysers:
There are several types of water analyser, which are usually used to measure the effect of chemicals and disinfectants. Chemical (pH) –
Disinfectant (Br, O3)
Types:
• Box of tablets and a graduated measuring jug.
• Litmus paper in a box.
Maintenance
Removing and cleaning the filter cassette
The filter cassette of the spa can become blocked by mineral particles through calcification by hard water. This can result in impaired
water flow. We recommend cleaning the filter once a week.
Remove the filter if the spa is going to stand unused for two weeks or more.
1. Remove the filter lid.
2. Remove the filters.
3. Clean with a high pressure nozzle to remove all dirt in the filter. NOTE not high pressure washing.
4. Soak the filter in warm water and Westerberg’s Filter Cleaner to remove all body oils and greasy dirt.
Never clean the filter using chlorine!
5. When inserting the filter, be sure to soak the filter in the spa water and insert the filter into the filter cartridge when the felt is
under the water to avoid getting air into the system.
Care instructions for spa cover
In order for your spa cover to last a longer, we recommend that it is dried regularly. Avoid leaving snow and dirt on for too long.
Your hot tub is equipped with a closable hard vinyl cover. All types of vinyl are sensitive to UV radiation. Direct sunlight and mold can
damage the casing. Maintenance of the cover is part of the regular the maintenance program. Landskap of Sweden leaves no warran-
ty on the lid.
