Operation Of Heating Or Air-Condition With Tractor´s Work; Immediately After Cooling The Cabin; Air-Condition And Heating Registers (A) - Zetor FORTERRA HD Series Operator's Manual

Operation of heating or air-condition with tractor´s work
With engaged inner recirculation of air is the inflow of
fresh air closed and there is foul air in the space of the
cabin by operator. This state can cause the feeling of
fatigue and there can also be penetration of dust to the
cabin because of the loss of surplus pressure.
Note: Set the control (D) according to individual
requirements on temperature to the position between (a)
and (b) so that the ventilator sucks the air from the outside
of the cabin through filters, when working.
When spraying pesticides and using the
heating filter with active carbon, the recirculation
controller should be in position 'air is drawn into from
the outside' and the fan controller should be in the
position 'fan maximum work' to create overpressure
in the cabin.

Immediately after cooling the cabin

Immediately after cooling the cabin and lowering the inner
temperature on the required values, we recommend the
following:
- Switch over the control of air circulation (D) from position
(b - air re-circulation) to position (a - outer air suction)
- Do the continuous regulation of the air temperature with
air condition on by opening the heating valve (A). The air
entering the cabin from expiration is not so intensively
dried with this setting.
- Continuous temperature control with air-condition on can
be also done by lowering the output of ventilator by
switching the control (B) to position 1 or 2.
