6.6 Turning off
To turn the air conditioner off, set the switch Fig. 20
Ref. (2) at the position "0".
After turning off the air
conditioner, using the thermostat knob or else
the ON-OFF switch, you must wait at least 3
minutes before turning it back on again, in order
to allow the refrigerant to stabilize its pressure.
Failure to comply with this rule may lead to
irreparable damage to the compressor of the
air conditioner.
6.7 Safety rules
Always use power sockets which are connected
to earth and are protected by differential cut-off
switches.
Never use the air conditioner near flammable
liquids.
Never use the air conditioner for any purpose other
than those provided for by the Manufacturer.
Do not modify or tamper with any part of the air
conditioner.
Use original spare parts.
Maintenance and repairs must be carried out by
specialized personnel.
Installation must be carried out by specialized
personnel.
Do not put your hands inside the ventilation grids.
Do not put any foreign matter into the ventilation
outlets.
Should the air conditioner suffer from any forceful
impact, have specialized technicians check it out
before using it again.
In case of fire, never open the top lid of the air
conditioner, but use approved type fire extinguishers.
Do not use water to put out fire.
6.8 Troubleshooting
If the air conditioner fails to work properly, this usually
will not be due to a fault but simply to improper use.
For example:
The air conditioner is undersized compared to the
volume of air to be conditioned.
The walls of the vehicle are not sufficiently
insulated.
The doors are opened too frequently.
There are too many people inside the vehicle.
The voltage is less than 205 V.
Following is a list of possible problems, which could
be encountered, their reasons and how to solve
them.
If the air conditioner is working
poorly, first make sure:
That the power supply is never less than 205 V;
The suction filters are not jammed;
The air diffusion outlets are open;
1) The air conditioner fails to start up:
• make sure that the cool air / warm air switch Fig. 20
Ref. (2) is not in "0" position and that the thermostat is in
its all-cool position Fig. 20 Ref. (3) .
• Then make sure that the sockets are powered,
connecting a household appliance or using a voltmeter
.
2) The compressor does not work:
• for the compressor to work, the thermostat Fig. 20 Ref.
(3) must be set at a temperature at least 5 degrees lower
than that of the indoor environment of the vehicle and the
warm / cool selector must be in cool position .
3) The evaporator fan does not work:
• make sure that the ON-OFF switch Fig. 20 Ref. (2) is
not in "0" position and that the fan speed selector Fig. 20
Ref. (1) is not blocked in an intermediate position.
4) The condenser fan does not work:
• call in a technician
5) The heating resistor does not work:
• make sure the cool / warm selector is in the warm
position Fig. 20 Ref. (2).
6) The air conditioner has a poor yield:
• if the air conditioner has a poor yield, you must
clean the air filter, the condenser and the evaporator,
using specific detergents. We suggest washing the
air conditioner before using it, after a long period of
time during which it has not been used. If the air
conditioner does not recover its initial yield even
after the exchangers have been cleaned, check the
load of the refrigerating gas.
