The switch of a high pressure of the conditioner

 The switch can be defined on red colour of the case (it is specified by an arrow).

Switches off the conditioner compressor if pressure of a coolant increases too highly.

This switch can be removed, without lowering system of cooling of the conditioner.

The inhaling moment: 10 Н.м.

The switch of a high pressure of a coolant

 The switch has the yellow or green case with welded connections (it is specified by an arrow).

Switches the fan cooling a radiator, in the second operating mode when pressure of a coolant reaches certain value.

The switch can be removed, without lowering system of cooling of the conditioner.

The inhaling moment: 10 Н.м.

Switches off the conditioner compressor if pressure of a coolant increases too highly.

This switch can be removed, without lowering system of cooling of the conditioner.

The inhaling moment: 10 Н.м.

The switch of a high pressure of a coolant

 The switch has the yellow or green case with welded connections.

Switches the fan cooling a radiator, in the second operating mode when pressure of a coolant reaches certain value.

The switch can be removed, without lowering system of cooling of the conditioner.

The switch of low pressure of a coolant

 The switch supervises evaporator temperature, periodically switching on and off the conditioner compressor.

The switch as switches off the compressor, when pressure of a coolant too low.

The switch is located from outside the passenger between a casing of the evaporator and the fire-prevention partition separating salon from the engine.

The switch can be removed, without lowering system of cooling of the conditioner.

Removal

PERFORMANCE ORDER
1) remove a dividing partition under a ware box
2) remove the block of management of fuel injection (it is specified by an arrow)
3) remove the switch of low pressure of a coolant
The prevention

Necessarily use goggles and gloves when remove the switch of low pressure.
