Water and steam connection
Connect the flexible ¾" water connection tube in the packaging to the water connection in the installation panel of the
unit and to the cold water piping of the building. The water pressure must be between 0.2 and 10 bars. The water
supply pipe must have a manual stop valve for stopping water supply to the unit, if the unit is not used for a prolonged
time.
Installation must follow the local regulations
It is recommended to use at least 18x16mm (steamer size 3.4 kW-9.5 kW) and 22x20mm (steamer size 12.0 kW- 14
kW) copper pipe or a silicone tube of similar size when connecting the steam pipe. The steam pipe diameter must be
the same for the whole length.
The steam pipe must be tilted upwards or downwards from the steam generator to the steam room, there MUST NOT
be any water seals or water pockets. The condensation water forming in the steam pipe must be allowed to drain
freely to the steam room or back to the steamer. If a scent pump is connected to the steam generator, the pipe must
ALWAYS drain away from the steamer, so that the chemicals cannot get into the tank.
Recommended maximum length for the steam pipe is 5m.
It is recommended to always use additional insulation for the steam pipe, for both safety reasons and to prevent
water condensation in the pipe.
WARNING: Hot steam can cause burn injuries.
The magnetic valve for draining the steamer's tank is fitted into the draining pipe. Alternatively you may use a manual
draining valve.
The steamer's tank should be drained after each use. This will extend the unit's life and reduces chalk build-
up
