1 - heat exchanger (heater radiator)
2 - left half of the body
3 - mounting bracket
4 - right half of the body
Doesn't understand.
5 - connection board
With pre-resistors; replace as a set.
6 - fresh air damper
7 - temperature damper
8 - fan
9 - air duct of the leg compartment
Screwed with 3 bolts to the heater.
Fresh air for the heater enters the passenger compartment through the heater ventilation system. In this case, the air flows around the heater housing and exits through various flaps to individual air outlet nozzles. If the heater is installed "Warm", then the cold air is heated by a heating radiator. The radiator is located in the heater housing and is heated by hot coolant. The flowing fresh air is warmed up by the hot sections of the radiator and then exits into the passenger compartment. Heating is regulated by air, i.e. temperature The ratio of cold and warm air is set using the temperature damper.
To increase the power of the heater, a four-stage heater fan is used. To set different fan speeds, resistors are connected. These resistances are located on the fan connection board. In the event of a defect, the connection board is replaced as a set.
