1.17. Heating and ventilation

Central ventilating nozzles

Fig. 1.28. Central ventilating nozzles: 1 – rotary switch; 2 – indicator; 3 – handles of manual adjustment


The central rotary ventilating nozzles can automatically turn (fig. 1.28). They are again switched off by repeated pressing of the switch. At the switched-off rotary nozzles it is possible to adjust the direction of an air stream manually.

Side ventilating nozzles
Air streams it is possible to regulate independently one from another.

The amount of air arriving through a side ventilating nozzle depends on the frequency of rotation of the fan.

Ventilation is switched off.

The amount of the arriving air depends on the speed of the movement of the car.

PREVENTION
At the switched-on conditioner install the lever on
or on
For heating install the lever in situation.
If the lever is installed in situation,
there will be a defrosting of side glasses.

Control panel of heating and ventilation 

Fig. 1.29. Control panel of heating and ventilation: 1 – lever of adjustment of distribution of streams of air; 2 – the switching lever "the fresh / recirculated air"; 3 – switch of frequency of rotation of the fan; 4 – lever of adjustment of air temperature


The control panel of heating and ventilation is shown in fig. 1.29.
Adjustment of a stream of air.
By means of the lever of adjustment of distribution of streams of air it is possible to establish an air outlet from various ventilating snuffled.
Switching "the fresh / recirculated air".
By means of the switching lever "the fresh / recirculated air" can be established giving in interior of the car either fresh air, or the recirculated air.
Adjustment of temperature.

Fig. 1.30. The provision (a) of control levers heating and ventilation at adjustment of air temperature, the car given to salon


By means of the lever of adjustment of temperature it is possible to adjust air temperature, the car (fig. 1.30) given to salon.
Switch of frequency of rotation of the fan.
The switch can be installed in the following provisions:
OFF – the fan is switched off;
1 – low frequency of rotation;
2 – average frequency of rotation;
3 – high frequency of rotation;
4 – very high frequency of rotation.
Switching off of supply of fresh air.
Switch off the fan. Install the switching lever "the fresh / recirculated air" in the relevant provision. Close side ventilating nozzles.
Air supply in the top space of salon and to the area of legs.

Fig. 1.31. The provision (a) of control levers heating and ventilation at air supply in the top space of salon and to the area of legs


It is carried out after installation of the lever of adjustment of distribution of streams of air in corresponding provisions (fig. 1.31).
Heating.

Fig. 1.32. The provision (a) of control levers heating and ventilation when heating interior of the car


For heating of interior of the car install levers on control panels of heating and ventilation in the provisions shown in fig. 1.32.
Heating and defrosting.

Fig. 1.33. The provision (a) of control levers heating and ventilation during the heating and elimination of frosting


For heating and elimination of frosting install levers on control panels of heating and ventilation in the provisions shown in fig. 1.33.
Elimination of frosting of a windshield.
Before beginning the movement, clear of ice and snow wind, side and back flew down, and also a rear-view mirror.
Remove ice and snow from a lattice for air supply to increase efficiency of heating and work of a heater, to prevent fogging of a windshield.

Fig. 1.34. The provision (a) of control levers heating and ventilation during the heating and elimination of frosting


For heating and elimination of frosting of a windshield install levers on control panels of heating and ventilation in the provisions shown in fig. 1.34.

Conditioner
Operating mode of the conditioner
1. Close side nozzles of supply of fresh air.
2. Install the lever of adjustment of temperature in required position.
3. Launch the engine, press the switch of the conditioner and establish the required frequency of rotation of the fan.
4. Establish the maximum productivity as follows.
Move the lever of installation of temperature up to the end to the left, the switching lever "the fresh / recirculated air" in situation "recirculated air" and establish the frequency of rotation of the fan in the 4 mode (see fig. 1.29).
Conditioner switch
The conditioner can be included or switched off pressing of the switch of the conditioner.

PREVENTION
If the conditioner is not used for an appreciable length of time, it nevertheless needs to be included once a week for several minutes for lubricant of internal details of the compressor of the conditioner.
