5. Cooling system and heating
| |||
| Design | |||
| Thermosiphon with the bladed water pump. Thermostatic adjustment. With a separate broad tank. The fan with the electric drive, joins and switched off from the control unit | |||
| Cooling liquid: mix of soft water and antifreeze (1:1), at such structure is provided frost resistance to –37 °C | |||
| Antifreeze | MB No. Q1 03 0002 or Glysantin Protect Plus/G482

| ||
| Composition of cooling liquid | |||
| Antifreeze share in cooling liquid for ensuring frost resistance | |||
| to -37 °C | 50%
| ||
| to -45 °C | 55%
| ||
| Pressure in system | About 1.2 atm. (the exact size is specified on a cover of a broad tank). The cover has to maintain pressure within two minutes.
| ||
| Thermostat | |||
| Valve stroke | not less than 8 mm

| ||
| Fan thermoswitch | |||
| Inclusion/switching off of the 1st step | 92-97/84-91 °C
| ||
| Inclusion/switching off of the 2nd step | 99-105/91-98 °C
| ||
| Stopper of a broad tank | |||
| The valve of excessive pressure opens, atm. | |||
| Step 1 | 1.4 ± 0.1
| ||
| Step 2 | 2.0 ± 0.1
| ||
| The valve of depression opens | 0.1
| ||
| On a cover pressure of opening of the valve is specified in atm. x 100. If, for example, on a cover costs "140/200", it is about a two-level cover and pressure of opening of the valve makes 1.4 and 2.0 atm. | |||
