We work like this: drain “Tosol” from the radiator of the stove (about 1 liter), dismantle the heater and the standard air intake along with the drive. Instead of the latter, we install a water separator made according to the sketches, sealing the plane of the connector with suitable material. From above, the structure must be covered with a purchased plastic deflector - it will provide the necessary support during movement. With the "native" heater, we cut the fan case with the "grinder". We fix the new case with the filling (fan from Samara) with four self-tapping screws. Having installed the stove in place, we use couplings to connect the guide pipes with hoses that supply air to the windshield. The pipes themselves are plumbing bends with a diameter of 50 mm, and the panel where they are inserted is a piece of rubber 5 mm thick, in which two holes with a diameter of 40 mm are knocked out by a notch. Couplings - the same corrugated hoses of slightly larger diameter - guarantee a small (but, in experience, quite sufficient!) Leakage of warm air to the legs. It remains to glue the heater with vibrothermal insulation and finally enjoy the wonderful views opening through the clean and dry windows of the car.
