Chemical composition of the water
The chemical composition of the water in a spa
system is extremely important. Chemicals are
used to clean the water and regulate the pH
balance. High water temperatures combined
with a small volume of water requires careful
monitoring of the chemical balance of the water.
We recommend that you get a starter kit with
chemicals from your supplier as well as any
extra materials that you will need to maintain
the correct/ideal chemical balance.
Cleaning
Cleaning the water in your spa ensures that
dangerous organisms are destroyed and that your
spa stays safe and healthy. Two frequently used
cleaning or oxidation agents for spas are chlorine
and ozone. Chlorine is a chemical product that
you add to the water. Ozone is a gas which is
produced by an ozonator and then injected into
the water. It is important that there is always
some water cleaning agent in the water. High
water temperatures, ventilation and regular use
increase the need for water cleaning agents.
Besides containing the agents, the spa water
must also go through additional regular cleaning
processes. This is also the case after intensive use.
Adding large quantities of water cleaning agents
thoroughly disinfects the water, and organic
residue that cannot be filtered out is oxidised.
Let the water cleaning agent drop to the residual
level before adding any more. If the spa is used
intensively, also use the cleaning cycle for extra
filtration (see page 17).
You should test the water quality daily using
the tester kit. Chlorine residue: free chlorine
level minimum 1.5 mg/l, bound chlorine level
maximum 0.2 mg/l.
pH level
pH is the balance of acidity and alkalinity in the
water. Maintaining the right acidity is important
for the effectiveness of the water cleaning agent,
the comfort of the users and for the prevention
of corrosion in the spa equipment.
Warning: never mix different chemical products.
Warning: never store chemical products in the
equipment compartment.
Warning: never use hydrochloric acid to
balance the acidity, as this product will damage
the surface of your spa and the equipment.
Recommended levels
pH : 7.0-7.5 (7.4 is ideal)
Free chlorine : 1.5 mg/l
Bound chlorine : 0.2 mg/l
Total alkalinity : 80-100 mg/l is ideal
for tricholrine
NOTE:
Make sure that you do not use any old test
strips or chemicals. Tester kits and testing
chemicals must be stored in a cool, dry place.
Check how long you can store the chemicals
and their expiry date.
