User and installation manual HNS-T1
Water and steam pipe connections
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 local regulations
It is recommended to use at least 18x16 mm (steam generator's size 3.4 kW-9.5 kW) and 22x20 mm (steam
generator's size 12.0 kW- 14 kW) copper pipe or a silicone tube of similar type 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 generator. If a fragrance pump is connected to the 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 5 metres.
It is recommended to always use additional insulation for the steam pipe, for both safety reasons and to prevent
water condensation in the pipe.
Clearance from an uninsulated steam pipe to flammable material such as wood must be at least 10 mm.
WARNING: Hot steam can cause burn injuries.
The electromagnetic valve for draining the steam generator's size tank is fitted into the draining pipe. Alternatively
you may use a manual draining valve. Connect the downpipe (copper pipe with inner diameter of at least 16 mm) to
the draining valve (manual or automatic)
of the steam generator.. The downpipe is led to the nearest drain outside the steam room. The temperature of the
discharge water is 90 to 95° C.
IMPORTANT!
Regardless of where the downpipe is led, it must fall all the way from the steam generator to the drain. To ensure
adequate fall, you may have to place the steam generator on a wall mount or on a stand.
Steam generator's tank should be drained after each use. This will extend the unit's life and reduce chalk
build-up.
The product's warranty will be void if the steam generator has been incorrectly installed or it has been used
in a manner other than described in the user manual.
The warranty also expressly excludes operational faults if they are caused by hard water i.e. water with high
levels of chalk, or otherwise impure water.
The steam generator must be maintained as described in the user manual.
