3. Setting up your HYDR
IM
3.4 Testing water quality
The HYDR
IM
C61wd G4 is equipped with
a built-in water softening system that must
be adjusted according to the local water
hardness. To read local water hardness,
proceed as follows:
The water test kit included with your
HYDR
IM
contains three water
hardness test strips in bags. Take a
water sample from the location where
the machine will be installed.
1.
Open one of the bags, remove the
test strip and dip it into the water.
2.
Compare the color of the strip with
the chart on the back of the bag
Determine the water hardness
according to the chart on the water
test kit envelope.
3.
Power the unit on and select the
Settings key from the main menu.
4.
Go to the Setup Menu and select
“Set Regeneration”.
5.
Using the up and down arrows, set the
water softener regeneration level
according to the water hardness table
in this section. If your water hardness
falls between two settings, select the
higher setting.
6.
Unscrew the water softener container
lid from the bottom left of the chamber
and pour 0.5 litres of water into the
water softener container.
7.
Add 0.5 kg of water softening salt to
the water softener container, using
the supplied funnel to prevent any salt
from spilling into the chamber, and close
by screwing the lid
tightly
back into place. An improper seal can lead to corrosion.
*Please note: The water test strip is only accurate up to 250 ppm. If the reading on the test strip exceeds
250 ppm and/or if the location in which the HYDR
IM
is installed has known water quality problems, having
a more detailed and accurate water test done by a test lab is strongly recommended.
