Safety instructions for the electrical system:
Dangerous electric voltages may exist within electrical power or control lines which
can cause lethal accidents. In addition to generally applicable basic regulations, the
following rules must be observed for any servicing or maintenance work:
• Regularly check the power connection visually (connecting cables and plugs). In
case of visible damages, these parts must be replaced immediately.
• Always disconnect the supply mains from the snowmaker before starting any
service or maintenance works and secure it against inadvertent switching on.
• In case of malfunctions call in an expert. Problems resulting either from
malfunctions of the machine or within the installation must be solved before
operating the snowmaker again.
• Except for normal maintenance works, such as checking the connections and
the cables, all modifications or replacements on the electric control system must
be done by qualified personnel only.
Safety regulations for the hydraulic system:
The operating pressure of the snowmaker is maximum 40 bar. These pressures
involve high forces which may cause injury in case of defects. When connecting
the machine with the pressure water pipe, the following must be observed:
• Use only hoses and couplings rated for this operating pressure. Ordinary fire
hoses are not suitable for snowmaking installations.
• As with the cables, the hoses and couplings should also be checked regularly in
order to eliminate defective parts immediately. Since modern hoses are double-
plied, even a hose which is still leak-proof on the outside may be defective.
• Defective hoses should only be repaired by a company which is specialized in
this field and experienced with hoses of this pressure rating. During operation, a
force of up to 800 kg is applied where the hose is connected to the coupling,
therefore appropriate know-how is required for casing the coupling.
• Never try to open up a frozen hose with pressure water. The accumulation of ice
in the hose could cause damage to the snowmaker (valve block, water filter,
etc.).
• Never apply pressure to a hose which is connected at one end only. Pressure
thrusts can cause highly radial forces which may result in injury.
• Always roll up hoses for transport and put them on the floor of the vehicle –
never drag hoses behind a groomer (snowcat) or a ski-doo.
