low pressure snowmakers are almost maintenance-free. However, you
should observe the following short remarks.
3.1. Summer service:
We recommend conducting a revision of the snowmaker after every snow season,
directly before storing the machines during summer time. Enclosed you will find a
check list for the work to be done.
3.2. Compressor:
The time to make the first oil change after 50 operating hours must be strictly
observed. Later oil changes should be done after the season or after 500 operating
hours.
Oil quality: MOBIL RARUS SHC 1024 or equivalent oil only
3.3. Nozzle ring:
Despite pre-filtered water, it may happen that one of the tiny atomizing-nozzles
gets stopped up. With the help of the added tools, the nozzles can easily be
unscrewed for cleaning.
Correctly spraying nozzles are a condition for trouble-free operation of the
snowmaker. Stopped-up nozzles lead to an icing on the nozzle ring.
3.4. Water filter:
To avoid strong soiling of the filter we recommend, as well as a protection for the
high pressure centrifugal pump (pumping station), the installation of a water filter in
the pumping house, unless the water supply is provided directly from the mains.
The cleaning intervals of the filter depend on the degree of pollution of the water.
Particularly for new snowmaking installations the filter should be checked more
frequently on account of dirt accumulated in the pipes throughout installation work.
Flush pipes and system carefully before use.
The filter insert is taken out and cleaned carefully in hot water and soft soap. Use
a brush if necessary. DO NOT USE STRONG WATER JET!
