Adjusting the Water Softener
Water hardness will vary according to
the area in which you live. The more
limestone and mineral salts your water
contains, the harder it will be. Ask your
local Water Board to tell you the degree
of water hardness in your area.
This appliance is fitted with Water
Hardness Adjusters which the user may
adjust to suit his or her own needs.
Fitted inside the Water Softening Unit
are two coloured bars: a red one and a
white one.
The white bar is for water with a soft-
to-medium degree of hardness, which
measures up to 22 Clarke degrees.
The red bar is for area with very hard
water measuring from 22 Clarke
degrees to 34 Clarke degrees. The
white bar is fitted in an active position
and the red bar is fitted in a storage
position to prevent it from getting lost.
They slide in and out and are easily
interchanged. (Fig. 9).
