Adding Salt To The Pool - BWT EES Notice De Montage

illustrated in the diagram, or failing this a contactor with 2 power inputs/ outputs for the pump and a relay
for the EES, both slaved to the filtration timer.
The power rating of the panels are as follows:
Panels for pools up to 80 m3 = 0.6 A
Panels for pools up to 150 m3 = 1.2 A
To connect the control panel to the contactor and the contactor to the mains, we recommend that you use
cables with a strand cross section of 1.5 mm
of 2.5 mm .

ADDING SALT TO THE POOL

Before adding salt to the pool, check that the each of the water equilibrium parameters are within range:
• pH, ideally between 7.2 and 7.4 with EES
• Calcium hardness (water hardness = concentration of dissolved calcium), between 200 and 400 ppm
• T.A. (total alkalinity), between 80 and 120 ppm
Use these parameters to ensure that the water is correctly balanced (Taylor balance or Langelier index –
see appendix 1)
!
IMPORTANT If the pool was treated with PHMB in the past, eliminate all of this disinfectant before
starting the electrolyser.
!
Only use pool grade salt as stipulated in the standard EN 16-401. No other types of salt should
be used.
If the pool has not just been entirely refilled, measure the salt concentration with a suitable device because
it may contain a little salt if the water was treated with Chlorine before the electrolyser was installed.
Calculate the weight of salt to be dissolved to achieve a concentration of 3.5 g/litre (3500 ppm) in the pool
water. This will depend on the volume of water in the pool (do not forget the buffer tank if the pool has an
overflow feature), and the initial salt concentration measured beforehand.
