Air-conditioning system control device
To ventilate the cab with the evaporator in the roof of the cab: Turn the air conditioner off with the button S2. Turn the blower fans on with the button S1. Select the desired air flow with the rotary switch S1 and the vents of the evaporator.
Heater operation Move the lever 1. The amount of water running through the heat exchanger can be regulated. If the regulator is pushed all the way to the rear, the maximum amount of coolant flows to the heater. Set the desired air flow with the button S12. Move the lever 2. The amount of fresh air recirculated and entering the cab is regulated. Note! The best heating effect can be reached when the air is recirculated, which means, the lever 2 should be pushed all the way to the front. In this position, a small amount of outside air is mixed with the recirculating air in the cab. To quickly defrost the windshield:
Push the sliding regulator 3 all the way to the rear. So the maximum air flow is blown via the vents in the step onto the windshield. When the lever 3 is pushed all the way to the front, part of the warm air flow is blown against the left side window.
Air conditioner operation The cab has an air-conditioning system as standard. The air-conditioning system is used to cool and ventilate the cab.
