PREVENTIVE MAINTENANCE
- Refrigerant Gas R134a
VALEO Climatização do Brasil - Veículos Comerciais S/A products apply for
R 134a. The se of different type of gas, low quality or from unknown brands will
cause low performance from the refrigeration and damage the equipment
components. - Ducts
The cleaning of the air ducts must be done every tree months, it can be earlier,
depending on: the frequency of operation of the air conditioning system,
quantity of passengers and resistivity of the environment where it is driven. This
cleaning is the responsibility of the vehicle owner´s only, he is in charge of this
cleaning in order to offer good air quality to his passengers.
NOTE: ducts are components of the bus body.
- Pulley Belts
In order to increase the lifetime of the belts, the strength/stretchiness must be
as low as possible, but working, not leaving them skidding without any friction.
Too low stretchiness on the pulley belts can cause overheat and too much
skidding, causing early break.
Too much stretched belts diminish their lifetime and from roll bearing and from
sleeves, this problem can cause engine interior and compressor damage.
After changing the belts, check their stretchiness back again after 48 working hours.
It is recommended not use different brands. Install assemblies with the same
diameter/length of the series and do not apply new belts beside old ones.
Putting the assembly into action without one or two belts for a long time can
cause a damage inside the “v” groove of the pulley. It will cause wear in that
“v” groove, so the new belt may not be stretched accordingly.
The application of reconditioned parts will diminish the air
conditioning efficiency, will overcharge the electric system causing
early brake of the compressor and set a fire!
- Oil
We recommend you that you shall preventively change the air system oil every
two years or 10.000 working hours, whatever becomes first.
- Dry Filter
We recommend that you shall preventively change the drier filter every 3 years.
Just in case, you need to refill in the equipment with gas, we recommend you
replace to a new filter to extinguish any dirt out of the system.
- Heating system
We recommend that you enable the heating system frequently (once a month)
to prevent the buildup of solid system particles that lodge in the hot air shutoff
valve seat.
- Compressor Sealing Part
In order to avoid leakage at the sealing part of the compressor due to lack of
lubrication, then the air conditioning must be working at cool mode for at least
15 minutes, once every 15 days.
The sealing part is lubricated by the compressor oil and in its normal operation
allows a small leakage of 0.05 ml per hour under operation.
Check frequently the reservoir and/or felt then remove the excess of it.
Dispose the old oil as your Country regulations and laws.

Condenser Fan
Condenser fan and the compressor will only work at
“Cool Mode”.
Refrigerant Fluid
Its main goal is dissipate the heat out, which was
absorbed by the refrigerant fluid along the
refrigeration system.
At the condenser, the overheat refrigerant fluid is
sent to outside losing its force, changing from
gaseous state to liquid state.
Condenser
Dryer filter
Valve hinders the refrigerant inlet that comes from
de condenser at high pressure and its goal is adjust
the refrigerant gas flow that passed by the
evaporator looking for making the pressure steady
and temperature at the capillary tubes output.
Compressor
When it is working, the compressor sucks the refrigerant
fluid from evaporator at gaseous state and under low
pressure, compressing it, so temperature and pressure
increase, then the compressor puts it into the condenser.
MECHANIC SYSTEM
Compressor Operation
It is started up by the vehicle engine though a
pulley-and-belt system and put into action by an
electromagnetic clutch when air conditioning is
operating at “Cool Mode”.
Air refrechment
This permits the entry of the exernal in order to expel
unwanted odors and impurities from the vehicle.
Evaporator Fan
Evaporator fans are working at cool and fan modes,
fans can be set in two speeds.
Sped control can be manual or automatic.
Temperature Sensor
The interior temperature is measured by the
temperature sensor placed at the air return spot.
Pressure Switches
Pressure switches are electric devices that monitor the air
conditioning equipment operation pressure. Every time a
strong change happens from the NORMAL temperature,
they turn off the compressor immediately to avoid break.
Observation: pressures are always monitored, even if the
air conditioning is turned off.
ELECTRIC SYSTEM
Evaporators
Now at evaporators, the refrigerant fluid, at low
pressure, turns from liquid to gaseous state,
absorbing the interior heat of the vehicle in this
process.
Controller
It is installed in the instrument panel, it offers to the
driver to set-point of temperature, to see by display the
interior temperature, offering full climatic control inside
de bus.
Set-point: it is the temperature the driver wishes to set
inside the vehicle for passengers.
Relay Board
Relay board has the controller controls, condenser fan
control, evaporator control and compressor control.
Air filter
Air return filter retains impurities from air avoiding
any block of dirt at evaporator capillary tubes and
coil.
Air circulation
Air being cooled by the evaporator, then it follows
to the bus interior through fans.
Drain
It is a way to get the condensed moisture from
evaporator tubes from the condensed tray to putting
out.

AIR CONDITIONING OPERATION
It is inside the air conditioning equipment, inside the
system. It works absorbing the heat from the interior
/ room of the vehicle, at the evaporator, and then it
goes to the condenser where the heat is thrown to
the outside. VALEO Climatização do Brasil - Veículos
Comerciais S/A, products apply refrigerant R134a,
according to the Protection Environmental Law.
It has the purpose of retaining impurities and/or
moisture that can exist in the system, preventing
them from leaking into the expansion valve.

Welding must be done carefully; it causes burns and
spray toxic gases out. Provide ventilated places to
do it.

toxic gases and can cause very serious breathing
illness. Take special care in closed places, if gases
scape somehow (leakage) and then it can cause no
toxygen in the air.
Other Care:
• When handling and going up and down stairs, ladders and platforms, you can
slide or they can break.
• Wear a seat belt always when working over 1.5m high.
