8.2. FANS
Clean the blades and impellers of the fans quarterly, as this can produce, in
addition to a decrease in flow, disbalance and disturbing noises.
Periodically check the flow rates of the fans.
8.3. FILTERS
To ensure the effectiveness of particle filters, it is necessary to control the
pressure loss that occurs in them (indicative of their degree of dirtiness).
It is recommended to change the absolute filter according to the set values of the
pressure switch indicated on page 12, when the switch light turns on. The
pre-filter once a year and the GRSystem filter, every 2 years.
Even if the maximum permissible load loss is not produced, the filters must be
checked monthly for the filter's tightness and filter's holder assembly.
It is advisable to have a set of filters always as a spare. Under no circumstances
will the operation of the equipment without filters be allowed as this could affect
soiling of vital elements of the equipment and therefore, their deterioration and a
loss of efficiency.
8.3.1. REPLACEMENT OF MAIN DEVICE FILTER
To extract the filter, the corresponding inspection record must be opened and
removed by sliding the filter outwards, for prefilter and GRSystem filter. The
high efficiency filters (H14) are provided with an anchoring system through the
safety handles.
In order to remove the filter, turn the upper and lowers handles and slide the
filter out.
Replace the filter and repeat the operation in reverse.
9. RECYCLE
The EEC regulations and the commitment that we must acquire with future generations
oblige us to recycle materials; we kidnly ask you not to forget to deposit all the
remaining elements of the packaging in the corresponding recycling containers, as well
as to take the replaced equipment to the nearest waste manager.
