The correct combination of chemicals in an indoor swimming pool is crucial, both for the
health of users and for the inventory inside the pool room and the swimming pool’s technical
room. Insufficiently treated water results in poor hygiene, while water that has been exces-
sively treated results in gases in the air that contain chlorine, which can irritate the eyes and
cause breathing difficulties.
At the same time, the incorrect composition of chemical ingredients in the water can destroy
all of the inventory in a very short space of time, including the dehumidifier and other equip-
ment that have been installed to process the air.
Shown below are the threshold values, which apply to products for indoor swimming pools
in accordance with EN/ISO 12944-2, protection class C4. These threshold values must be com-
plied with for the warranty to be valid.
The following guideline values are applicable to swimming pools with the addition of chemi-
cals.
Chemicals
ppm
Free chlorine content
1.0-2.0
Combined chlorine content
Max. 1/3 of free chlorine content
pH
7.2-7.6
Total alkalinity
80-150
Calcium hardness
250-450
Total dissolved solids
< 2000
Sulphates
< 360
The following guideline values are applicable to swimming pools with self-production of
chlorine:
Chemicals
ppm
Salt (NaCl)
< 30,000
Total dissolved solids
< 5500
pH
7.2-7.6
Total alkalinity
80-150
Calcium hardness
250-450
Sulphates
< 360
It is advisable to use the Langelier Saturation index to ensure that the combination of the
different water parameters is acceptable.
Contact Dantherm A/S if necessary.
• The CDP 40T-50T-70T units are designed for installation in a heated room, adjacent to the
pool room.
• Do not place the dehumidifier close to a heating source, e.g. a radiator.
• Doors and windows must be kept closed when the dehumidifier is in function.
• To make sure that the room air passes freely through the dehumidifier, air inlet and air
outlet openings must be free.
