11 - USE OF THE WATER SOFTENER
11.1 - DIRECTIONS ON USE
As indicated in the table at section 10, periodically check the salt level in the brine tank is higher than the
water level, otherwise add further salt in the tank.
A too low level of salt in the tank may cause the following:
- excessive consumption of salt
- salty water at the outlet!
P.S. The salt alarm function, the AD water softeners are fitted with, solely indicates that the salt is not
enough for regenerating the resins and not that the salt level is too low!
Always use one the following kinds of GEL salt for refilling salt in the brine tank:
- SALT PR (code 410.600.44),
- SALT G (code 410.600.35)
Except from the clock updating and the programming of the time period for salt alarm, never modify the
programming of the Timer set by authorized Technical Assistance Service.
Every two months check water hardness by using the special kit supplied by Gel.
In case of fire, immediately cut off power supply, do not breathe the fumes caused by the combustion
(vessel and/or resins) and wear protective suit and breathing apparatus to enter the rooms.
11.2 - HOW TO MEASURE WATER HARDNESS
As mentioned, every two months it is necessary to check the water hardness at the outlet of the softener.
Should it be higher than 15 °f, please call the authorized Technical Assistance Service, carrying out the
start up and testing, for any inspections and adjustments.
For measuring the water hardness at the outlet, operate as follows:
Example: 20 drops = 20° f hardness
If 20 drops have been added to make the colour change, the water hardness will be equal to 20°
French degrees.
So each drop of reagent poured corresponds to 1 French hardness degree.
The value of the residual hardness for potable water recommended by GEL is 15°f.

Take the test tube supplied with the kit.
Rinse it out with running water, then fill it up to
the value “5 ml”.
Add a drop of reagent into the tube and shake
it slowly. The water will get reddish.
Repeat the operation by counting the drops
poured, until the water will get the colour of the
reagent used (dark green).
