5.1

Before usage

NOTE
Before switching on, make sure that the supply voltage
and frequency corresponds to the values of the air con-
ditioner.
NOTE
Make sure that the amperage provided by the external
power supply is sufficient.
NOTE
Always completely unwind the cable drum to prevent
the power supply extension cable to the vehicle from
overheating and loosing voltage.
NOTE
The extension cable must have a minimum cross section
of 3 x 2.5 mm².
NOTE
Make sure that the air outlet and intake grilles are not
covered by cloths, paper or other objects.
NOTE
After removing the remote control back cover, insert
two (2) AAA LR3 leak-proof batteries into the remote
control. Then replace the cover on the back.
NOTE
When using the remote control, point it at the air dis-
tributor to have the best signal transmission. The air dis-
tributor beeps as soon as it receives a signal.
NOTE
The icons that are shown in the remote control display
depend on the settings you are accessing.
NOTE
After selecting COOL or HEAT mode, the compressor
may delay starting for 3 minutes. This feature protects
the compressor.
NOTE
To set the system clock, see chapter chapter 5.10, "Set-
ting the system clock" on page 13.

How to heat and cool effectively

The following general measures are very useful to reduce the
heat load within a vehicle and improve the performance of the
air conditioner:
l Park your vehicle in the shade when possible.
l Position your vehicle with the sunshade facing the sun-side.
This reduces exposure to direct sunshine.
l Close all doors, skylights and windows, close the curtains
and open the sunshade or awning.
l Turn off within the vehicle, all electrical appliances running
unnecessary. This will further reduce the heat-load.
l Cook outside the vehicle when possible.
l In case of exceptionally high temperatures, turn on the air
conditioner in advance during the morning.

l If vehicle interior has already heated up, ventilate your
vehicle by opening doors and windows before starting the
A/C unit.
l Regularly clean the vehicle's roof; dirty roofs heat up more.
In the same way that many factors affect the total heat load
within a vehicle, many additional factors can affect the air con-
ditioner working efficiency. It may be advisable to consult your
vehicle manufacturer to fully understand the total heat load of
your vehicle.
5.3

Dealing with condensation

When warm and moist air within the vehicle meets a cold sur-
face, this is likely to result in condensation water. This is also
known as "sweating". To deal with this:
l Close and seal all doors, skylights, and windows. This re-
duces the entrance of warm moist air.
l Operate the inside fan on High fan speed, avoiding Low
and Auto fan speeds.
When operating the air conditioner, condensate water is pro-
duced and drained onto the roof. This is normal. The amount of
condensate water depends on air humidity. High humidity in-
side your vehicle will result in more condensate water being
generated.
NOTE
Losses or damages caused by condensate water are not
within the warranty scope.
5.4

Choosing and using a generator

The CTT 28 requires a mains-quality AC power source for cor-
rect operation. If you decide to supply power using a generator,
you must consult your generator supplier to confirm suitability
and sizing of the generator for your application.
NOTE
Damages caused by the use of a generator are not
within the warranty scope.
