Body (cabin) heating
For heating the driver's cabin and windshield there is a cabin heater with a radiator 13 (Fig.3.12).
For heating the passenger (sanitary) compartment of UAZ-396295, UAZ-390995, UAZ-220695 vehicles there is a
cabin heater with radiator 3. The vehicle UAZ-390945 has an additional heater which is installed depending on the
configuration.
To operate the heaters it is necessary to open the heating system tap 15 (Fig. 3.12) using the pull rod handle 16 (Fig.
3.1) and, if available, switch 9 (Fig. 3.3) to start the electric motor of the heater pump 2+ (Fig. 3.12).
The motors of the heater fan are switched on and off by switches 8 and 9 (Fig. 3.3).
The coolant temperature in the engine cooling system
must be at least 80 °C for the heater to operate properly.
At low ambient temperatures, use the head cabin insulation attached to the vehicle. The insulator is installed on the
radiator frame with screws.
Monitor the coolant temperature in the engine cooling system by adjusting the coolant temperature through closing
and opening the heater valve.
When draining the fluid from engine cooling system it is also necessary to drain the liquid from the heating system
through plug 17 (Fig. 3.12), after the heating system tap 15 was opened. Access to the plug at the front from the bottom of
the vehicle.
Sanitary equipment of UAZ-396295 vehicle
It is possible to place two standard stretchers in the sanitary compartment of the body, depending on the
configuration.
There are four hinged brackets on the sides of the sanitary cabin to install and mount a unified stretcher, and holders
for mounting of two suspension straps on the ceiling.
Accompanying persons and patients who are able to move are placed on the seats located on the right side of the
cabin: two - in driving direction and one against the driving direction.
To facilitate the movement of the stretcher on the floor, there are guiding rails installed that allow you to move the
stretcher along the body.
Transportation of patients
The UAZ-396295 vehicle body can accommodate from 4 to 6 people (not including the driver) with the following
options:
accommodation with a stretcher
(it is not allowed to use a stretcher while driving)
On the attendant seats ....................................................................................................................... 3 persons
In the driver's cabin .......................................................................................................................... 1 person
