The main parameters and technical characteristics of the air conditioning and cab
heating system are given in the table below:
Description of the parameter (characteristic) Value

Operating voltage, V 12
Electrical power consumption, W 260
Mechanical power consumption, kW 1.4 to 8.0
Coolant

To maintain the system in the
serviceable condition in case of non-
regular operation, it is recommended to
switch on the system in the cooling
mode once 15 days in the cooling mode
(at the outer temperature exceeding
15°С) for 15 -20 minutes.
Regardless the operating condi-
tions, it is necessary to check the opera-
tion of the system at the service station
using special equipment once a year.
When putting the tractor for short-
term storage, no preparatory works
should be performed for the air condi-
tioning system. During the storage, it is
necessary to switch on the air condi-
tioner with the engine running for 15-20
minutes once 15 days. In this case, the
air temperature in the tractor cab shall
not be below 20°С .
When putting the tractor for long-
term storage, it is necessary to check
the operation of the air conditioning sys-
tem using special equipment once a
year. If necessary, add coolant. During
the storage, no service works should be
performed.
When taking the tractor from the
storage, it is necessary to perform the ser-
vice of the air conditioning system at the
specialized service station using the di-
agnostic equipment.
Other information on the mainte-
nance and servicing of the air-
conditioning and cab heating system are
given in the Section “Scheduled Mainte-
nance”.
WARNINGS:
1 . Only the specially trained personnel shall be allowed to perform the maintenance and
repair of the air conditioning system components.
2 . Any works related to uncoupling of the air conditioning system components shall be
performed by the training personnel using special equipment for maintaining the air
conditioners. The system contains high pressure even in inactive state.
3 . Prior to stopping the tractor engine, make sure that the air conditioner is off.
4 . The r134a coolant is neither toxic, nor flammable. It does not form explosive mixtures.
The coolant boiling temperature under normal conditions is minus 27 ° C. If the liquid
