1.17. Heating and ventilation

Nozzles of giving of air

Fig. 1–50. A direction of streams of air submitted to salon of the car: 1 – to the bottom part of a windscreen; 2 – to wind and to lateral glasses; 3, 3а – to lateral glasses; 4 – in the top area of salon of the car; 5 – to feet



Nozzles serve for giving in salon of the warmed-up or cold air (fig. 1–50, 1–51).

Fig. 1–51. A direction of streams (3) air, submitted to feet of back passengers



Distribution of submitted air on nozzles is regulated by position of the handle With (fig. 1–52).

Fig. 1–52. The Control panel a heater: And – the handle of a choice of temperature of air for heating of the driver; In – the switch of steps of work of the fan; With – the handle of distribution of giving of air on nozzles; D – the handle of a choice of temperature of the forward passenger



For the account snuffled 1 (fig. 1–50) remains not misted over the bottom part of a windscreen.
Nozzles 2 can be opened separately or to close the latches located sideways.
Nozzles 3 and 4 can be opened separately or to close the rotary wheels located sideways.
Direction of the stream arriving from snuffled, can change in horizontal and vertical planes.
Direction of a stream of the top snuffled (3a) can change only in a horizontal plane.
Atomizers for air giving to feet are located under lobbies сидениями and cope together with nozzles 5.

Controls
A – the handle of a choice of temperature of air for heating of the driver. The temperature smoothly increases at handle turn clockwise.
In – the fan switch.
In position 0 fan is switched off.

With – the handle of distribution of giving of air on nozzles.

Air giving to feet is carried out through nozzles 5.
For increase in a stream of air close nozzles of ventilation 3 and 4.

Air giving to wind and lateral glasses and to feet is carried out through nozzles of ventilation 3, 4 and 5.

Air giving to wind and lateral glasses is carried out through nozzles of ventilation 1 and 2.

Giving of air from ventilating lattices of the panel of devices is carried out through ventilating lattices of 3 and 4 panels of devices. Nozzles of ventilation 1, 2 and 5 are closed.

D – the handle of a choice of temperature of air for heating of the forward passenger.
The temperature smoothly increases at handle turn clockwise.

Defrosting of glasses
• the switch Handle In establish in position III.
• Handles of switches A and D turn clockwise against the stop.
• switch C Handle establish in position.

Removal of a condensate with wind and lateral glasses is necessary for spending at high humidity of air, for example at a rain.
• the switch Handle In establish in position III or IIII.
• Handles of switches A and D turn clockwise.
• switch C Handle establish in position or.
• Close ventilating lattices of 4 panels of devices.

Fast warming up of salon of the car
• the switch Handle In establish in position III.
• switch C Handle establish in position.
• Handles of switches A and D turn clockwise against the stop.
• Open ventilating lattices of 3 panels of devices, ventilating lattices 4 close.

Comfortable warming up of salon of the car. After defrosting of glasses and warming up of salon of the car use a mode of comfortable warming up of salon of the car.
• the switch Handle In establish in position II or III.
• the Handle of switch A and D turn clockwise before reception of the demanded temperature.
• switch C Handle establish in position  or.
• Establish ventilating lattices of 3 and 4 panels of devices in desirable position.

Airing of salon of the car. In this mode fresh air moves in salon through ventilating lattices 3 and 4.
• the switch Handle In establish in position IIII.
• Handles of switches A and D turn against the stop counter-clockwise.
• switch C Handle establish in position.
• Open ventilating lattices of 3 and 4 panels of devices.
• That heating and salon ventilation worked reliably, an aperture for a fence of the fresh air, located before a windscreen, it is necessary to clear of ice, from snow and leaves.
• In any intermediate position it is possible to establish only handles And, With and D.
• Heating ability of system of heating depends on temperature of a cooling liquid in system of cooling of the engine, therefore fastest air in car salon heats up at the heated-up engine to working temperature.
• From salon of the car air leaves through ventilating apertures in a back part of a body – they should not be blocked.
