PREVENTIVE MAINTENANCE
Refrigerant Gas R134a
VALEO Climatização do Brasil - Veículos Comerciais S/A apply refrigerant R134a
to is products. The use of gas with different characteristics, like low quality or
dubious source will cause low refrigeration efficiency and it will also damage the
equipment components.
WARNING: refrigerant shall NEVER be discharged straight into the
atmosphere.
Oil
We recommend the preventive change of the oil of the air conditioning system
every 2 years or 10.000 hours of work, whichever occurs sooner.
Drying Filter
We recommend the preventive change of the drying filter every 3 years. In case
of complete loss of gas pressure load, we recommend replacing the drying filter,
to eliminate impurities that may be coupled inside the system.
Pipelines / Ducts
Cleaning the air ducts shall be carried out periodically every three months, and
this length of time may be reduced, depending on the use frequency of the air
conditioning system, the number of persons carried and the aggressiveness of
the vehicle's environment. This cleaning is responsibility of the owner of the
vehicle, it will bear all the poor air offered to its passengers.
NOTE: Ducts are components of the bus body.
Pulley Belts
For longer belt life, then the tension must be as low as possible paying attention
to NOT having pulleys sliding (skidding) on pulleys.
The low voltage causes the sliding, generating excessive heat in the belts,
causing premature breaks. Excessive voltage decreases the service life of the
belts, bearings and bushings, it can cause internal damage to the motor of the
vehicle and compressor.
After changing the belts, check the belt tension in the first 48 hours of operation.
It is recommended not to use different brands. Install sets with diameter /
length of the same series and do not use new belts mixed with old straps. The
use of the equipment having one or more belts missing for long time may cause
uneven pulley problem. This will make it impossible to properly install new
ones.
SAY NO TO RECONDITIONED OR REFURBISHED PARTS.
The application of reconditioned parts will decrease the efficiency of the air
conditioner and will overload the electrical system and may cause
premature breakage.
