6. Startup
For locating the components, see figures 2 and 3 .
6.1 Brine tank
Make sure that the brine tank (A) includes a filter bed of minimum
150 mm in height with 4-6 mm washed gravel, and that it is filled
with the correct food grade quality salt (see section
3.9 Salt
specifications ). The brine tank (A) must be kept full with salt at
high level.
The water level in the brine tank (A) is maintained by floater valve
(21).
6.2 Water softener
The water used to make the sodium hypochlorite should be
softened to less than 20 mg/l CaCO
3
. Hard water will scale the
electrodes and reduce efficiency.
The water softener regenerates automatically. The amount of
water that can be softened between two regeneration cycles is
depending on the installed meter disc (fig.
14 , pos. 3). The meter
discs are numbered. Which meter disc number is needed
depends on the water hardness of mains water supply at site.
Hardness ranges of meter discs, see section
3.10.2 Hardness
ranges and meter discs .
6.2.1 Manual regeneration
See fig. 13 .
1. Place a suitable screw driver at the screw on top of the
softener head (right side of softener) to move pin (1).
2. Push down and turn the screw clockwise until pin (2) is
positioned in regeneration start range (3) for regenerating the
left side of the softener.
– During regeneration pin (2) moves clockwise.
– Wait until pin (2) has left the respective "
BACKWASH
" range
and regeneration is finished.
3. Push down and turn the screw clockwise until pin (2) is
positioned in regeneration start range (4) for regenerating the
right side of the softener.
– During regeneration pin (2) moves clockwise.
– Wait until pin (2) has left the respective "
BACKWASH
" range
and regeneration is finished.
The softener is regenerated.

6.2.2 Exchanging the meter disc
See fig. 14 .
1. Remove screws of transparent cover at top of softener head
(detail A).
2. Remove transparent cover.
3. Remove balance piston (1) and spring (2).
4. Carefully remove meter disc (3) making sure all surrounding
parts keep their functional position.
5. Use a small screw driver to slightly push the locking device
(detail B) to the side, and insert required meter disc (3).
6. Refit spring (2) and balance piston (1).
7. Refit transparent cover and tighten screws.
– Pin (4) of cover has to be placed in space (5) of softener
head.

6.3 Checking the mains water supply
6.3.1 Water specification
Make sure that the water supply conforms to the required
standard of drinking water given in the specification below.
Ask your local water supplier for the specific values.
Warning
Prior to startup all system components and lines
must be checked for tightness!
Warning
Wear goggles when filling the brine tank with salt.
Warning
PVD (Pure Vacuum Dried) salt is not suitable for use
in Grundfos brine tanks!
