HSX STEAM GENERATOR SERVICING PROCEDURES:
The HSX steam generator has a programmed automatic function which drains and rinses the tank
after each use. (The electrically-operated drain valve is an accessory.) A long service life is also
achieved by emptying the steam generator tank immediately after use in areas where the water is
perhaps not of the best possible quality. However, draining the tank is not an alternative for the
regular removal of lime from the tank. It is also worth cleaning the surface sensor at times. These
procedures should be undertaken either by a service centre or some other professional person.
Testing water quality and lime removal for the HSX steam generator
Included with the steam generator test kit are testing strips, which are used to test the water supply
hardness as follows: dip the test strip in the water for about 1 second, pull it out and shake off the
excess water. After one minute, compare the colour of the strip with the colour code on the package.
Test result:
<
3
°
dH, Very soft water, Lime removal once every 500 operating hours.
>
4
°
dH, Soft water, Lime removal once every 100 operating hours.
>
7
°
dH, Moderately hard water, Lime removal once every 50 operating hours.
>
14
°
dH, Hard water, Lime removal once every 30 operating hours,
installation of a lime removal device recommended.
>
21
°
dH, very hard water, Install a lime removal device and retest water hardness.
These maintenance intervals are the maximum times as recommended by the manufacturer.
It can be worthwhile undertaking the removal of lime and cleaning of the surface sensor even
more frequently, when necessary.
Warranty for the equipment is void, if the steamgenerator has been installed or it has been
used differently to what has been stipulated in the (use instructions) manual.
The warranty also excludes functional problems, if they are caused by so called hard (with
high dH) or otherwise impure water.
The steam generator must be serviced as instructed in the user manual.
