Cleaning The Heating Filters; Air Filter With Active Carbon; Carbon Filter Installation Instructions - Zetor Proxima GP Series Operator's Manual

Cleaning the heating filters

Recover the filters positioned under the covering grills
over the windshield outside the cabin with regard to the
degree of clogging:
- by shaking
- by blowing with compressed air
Check the filters for clogging daily. Replace heavily
clogged filters.
The safety cab of the tractor is not equipped
with special filters of air aspirated to the cab. It does
not protect the operator from the effect of aerosols
and other harmful substances! Use a filter with active
carbon when working with harmful substances.

Air filter with active carbon

Filters with active carbon are installed instead of the
standard dust filter and they are replaced in the same way
as the normal filters. The filter must be inserted with the
white side towards the grill.
The filter is only used during spraying of pesticides; then it
must be replaced with a paper filter again as flying dust
would clog the carbon filter in a very short time.
During its use the recirculation control must be in the
position of 'air suctioned from the outside'.
The fan control must be in the 'maximum' position.
The filter does not provide complete protection
from toxic substances:
- When handling the filter wear protective gloves
- Do not clean or blow the filter with compressed air
Replace the active carbon filter every 200 hours
or 36 months (the production date is printed on the
filter). If you feel the smell of pesticides in the cab,
replace the filter immediately and have the cab sealing
checked. Used filters must be disposed of in
specialized collection centres.

Carbon filter installation instructions

1. Remove the old filter from the air duct orifice in the
place of its mounting.
2. Remove the protective package from the new filter.
3. Insert the filter into the air duct orifice in such a way to
make the air flow direction correspond to the flow direction
through the filter in accordance with the arrow on the filter.
The entering air must first pass through the white dust
filtration layer.
4. Check proper sealing of the filter.
5. Secure the filter.
