2 O PERATION
The machines are equipped in series with a 20 m long supply cable with a 5-pole
CEE- plug with nominal current 63 A.
The maximum distance between the snowmaker and the electrant depends on the
voltage in the general power supply and voltage loss in the power cables taken in
consideration. See the power requirements.
Use only flexible cables which are suitable for this temperature range. In any case
secure the cable against sliding off at the pull relief on the piling.
Normally the supply is for 5-poles (3L+N+PE).
Check the SENSE OF ROTATION at the fan. It must be in the direction of the
arrow. If not, exchange 2 phases in the supply.
Pay attention that all tapping stations are equipped with the same sense of rotation
and that the phases are not crossed for the connecting cables.
2.4. Startup of the snowmaker:
1. Always secure the snowmaker to the ground with the locking jacks.
2. Switch on the power. Then the heating for the valve block is automatically in
operation.
3. Switch on the heating for the nozzle ring. If needed also turn on the light.
4. Connect the water supply.
5. After the pre-heating time (approx. 10-30 min.), switch on the compressor.
Check the pressure by reading it at the pressure gauge (maximum 2 to 4 bar
without water).
Too high pressure indicates that a part of the nozzles is still blocked with ice.
Switch off the compressor, turn on the heating and repeat the operation after 2
to 3 minutes.
6. Switch on the fan.
IMPORTANT:
Do not turn on the fan if the ice or snow is blocking the fan or if ice can fall into
the fan.
