Instructions for Use and Installation Helo Steam Pro
Water and steam pipe connections
Connect the flexible 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 at least 0.2 Pa (2 bar) and at most
1 MPa (10 bar). 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 period.
Installation must follow the local regulations
We recommended at least 18x16mm (steam generator size 3.4 kW-9.5 kW) and 22x20mm (steam generator size
12.0 kW- 16 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 steam generator. If an essence pump is connected to the steam generator,
the pipe must ALWAYS drain away from the steam generator so that the chemicals cannot get into the tank.
Recommended maximum length for the steam pipe is 5 m.
We recommend that you 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 tank is fitted into the draining pipe. Alternatively you
may use a manual draining valve. Connect the downpipe (copper pipe with a minimum diameter of 16 mm) to the
downpipe of the steam generator. The downpipe is led to the nearest drain outside the steam room. The temperature
of the discharge water is 90–95 °C.
IMPORTANT! No stoppers (valves, taps, etc.) may be fitted on the downpipe.
Regardless of where the downpipe leads, it must descend all the way from the steam generator to the drain. To
ensure adequate descent, you may have to place the steam generator on a wall mount or on a stand.
The steamer generator's tank should be drained after each use. This will extend the unit's life and reduces
limescale 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 that 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 calcium, or otherwise impure water.
The steam generator must be maintained as described in the user manual.
