4.7.6.8 Maintaining the air conditioning
Maintain the air conditioning periodically.
IMPORTANT: If the air conditioning system has not been used for a while, free
the compressor before starting the engine by rotating the pulley nut with a
wrench.
CAUTION: Do not attempt to remove any part of the air conditioning
system.
NOTE: Make sure that the compressor starts. At low temperatures, the
thermostat prevents the compressor from starting.
• Do not attempt to repair the air conditioning system.
Contact an authorised Valtra workshop if problems occur.
• Clean the condenser at regular intervals to remove dust, insects and other
particles.
• Check that there are no leaks in the condenser, evaporator, hoses and
couplings.
• Check the cleanliness of the outlet pipe of the condensation pipe.
• Avoid contact with the refrigerant.
WARNING: If refrigerant ends up in your eyes, contact a doctor
immediately. Do not weld near the air conditioning system as
poisonous gas may be released. The maximum permissible
environmental temperature for the refrigerant pipes is 80°C.
• It is recommended to change the drying container of the air conditioning
condenser after every 2400 hours of operation. Contact an authorised Valtra
workshop for changing the drying container.
• If the air conditioning is not functioning properly, contact an authorised Valtra
workshop for checking of the system.
