Guidelines
The connection for the water supply line and drain outlet must comply
with the European Union’s current applicable standards DIN 1988/EN
1717 and DIN 1986/EN 12056. It may be necessary to install a check
valve. Local regulations must also be observed.
Lime deposits resulting from hard water have a considerable negative
impact on the service life of the steam generator. Systems that are used
commercially must always be equipped with a water softening system
to prevent the build-up of lime in the vaporiser tank. For privately used
systems, a water softening system is required when the water hardness
level equals 14° dH (approx. 2.5 mmol/L) or higher.
See the chapter on 2.4 Water hardness,
The water must be potable. The water pressure must be between
2 and 8 bar.
Connecting the drain outlet correctly
Correctly and incorrectly installed drain outlets
The diameter of the extending pipe must not be smaller than the drain
outlet on the unit.
The drain pipe must not have any sharp angles or kinks.
The drain outlet and escaping water are very hot. The outlet for draining
the vaporiser tank and the hose for excess pressure must be arranged in
