Note: Please contact HygroMatik if you wish to operate the unit
with softened water.
If using a water softening system, we recommend diluting the
softened water with normal tap water to produce an overall hard-
ness between 4-8°dH. This value can be set lower if the water
does not foam.
When blending softened water with deionized water (conducti-
vity = 5-20 µS / cm) it is to ensure that the mixture neither foams
nor is too low in conductivity.
When feed water contains softened water, the level of conductiv-
ity is typically higher at operating temperature. Install a Hygro-
Matik "cylinder star" to extend the service life of the electrodes.
6.2 Water Supply
» Install a shut-off valve (SV) in the supply line.
» Install a water filter (WF) if water quality requires it.
Note: Shut-off valve (SV) and water filter (WF) are not supplied
with the unit
» HygroMatik provides a water hose (56) with a cap nut at
both ends which can be used for water installation.
Install as follows:
» Screw and tighten the cap nut with its inner seal ring
around the water supply screw connection that pro-
trudes from the base.
Note: Tightening too much will destroy the fitting. The valve
strainer must be placed inside the solenoid valve.
