CoolAir RT780 Technical description
9
5 Technical description
The parking cooler can be used for variable air conditioning inside the vehicle. The
air in the interior is guided into the system through the intake grille, cooled, dried and
conveyed back into the interior through the blower nozzles. The system is operated
using the control panel or the remote control.
I
The system is fitted with a battery monitor. If the system is operated when the vehicle
ignition is switched off, the parking cooler switches off automatically as soon as the
supply voltage falls below a set level.
The refrigerant circuit of the parking cooler consists of four main components:
•Compressor
The compressor draws in the R-134a refrigerant and compresses it. This raises the
pressure and therefore the temperature of the refrigerant.
•Condenser
The built-in condenser works like a cooler or heat exchanger. The air flowing past
absorbs the heat and the hot refrigerant gas cools down and becomes liquid.
•Capillary tube
The capillary tube reduces the refrigerant from the higher condenser pressure to
the lower vaporisation pressure.
•Vaporiser
The vaporiser cools down the air flowing past and dehumidifies it. The refrigerant
absorbs the heat and vaporises. The cooled air is distributed within the vehicle
through an air outlet unit.
NOTE
The parking cooler can lower the temperature within the vehicle to a
certain level. The temperature depends on the type of vehicle, the
ambient temperature and the cooling capacity of your parking cooler.
For the cooling capacity of your parking cooler, see chapter “Technical
data” on page 20.

7.1 Tip for improved use
I
Observe the following instructions for use to ensure your CoolAir parking cooler is
used efficiently:
It is recommended that you:
•Park your vehicle in the shade when possible.
•Shade your vehicle when possible.
•If you do not have a vehicle air conditioning system, air out your vehicle well
before using the parking cooler. You should always cool down the vehicle
interior before a rest period using the vehicle air conditioning system.
•Keep doors and windows closed.
•Avoid any heat sources in the vehicle.
•Reduce the power consumed by other devices to ensure the maximum possible
operating time of the parking cooler.
•Select a suitable temperature and operating mode.
•Make sure that the blower nozzles (fig. 11, page 3) and the intake grille
(fig. 12, page 3) are not covered by cloth, paper or other objects.
Always observe the following:
•If you would like the parking cooler to match the colour of your vehicle, only paint
the upper shell casing of the parking cooler.
Only paint this when it has been removed. Use light colours when possible.
•Wash your vehicle regularly, as dirty driver's cabs heat up more quickly.
•Make sure that the performance of the parking cooler is not affected by other
sources of heat (e.g. waste heat from cold machines).
How to actively care for your parking cooler
•Perform regular visual checks of the seals, the upper shell casing and the grill,
ideally before the season starts.
•If necessary, remove any dirt and leaves from the system.
NOTE
The RT780 is designed as a stationary air conditioner for relaxing rest
periods. It can be used while driving, does not however replace the
engine-powered vehicle air conditioning system.

text Description Cause Remedy
LO The battery monitor has
detected low voltage.
The compressor switches
off immediately and the fan
is switched off after 20 to
30 seconds. The whole
system shuts down after
2minutes.
Connection voltage is too
low. The battery capacity is
not sufficient to operate the
system.
➤Brief under-voltage: No

➤The system switches itself
off: Charge the vehicle
battery or check if the
battery monitor has been
correctly set.
HI The system has detected a
brief or constant over-
voltage.
A brief over-voltage may
occur when large electrical
consumers are switched off.
Constant over-voltage is the
result of an incorrect con-
nection voltage.
➤Brief over-voltage: No
action required.
➤If the display message
“HI” remains visible for a
longer period: Check the
vehicle electronics. Make
sure the connection
voltage is less than
30 volts.
HO The system has detected a
brief electrical overload
and switches the
compressor off.
The current power require-
ment of the compressor is
too high.
➤The brief overload is

the compressor. The
compressor starts up
again after a short time.
The system has detected a
too big inclination.
The compressor is
switched off. 5 minutes
later, the entire system will
be switched off.
The compressor (driver's
cab) is tilted too far.
