Operating instructions

5.1

Before usage

NOTE
■ Before switching on, ensure that the sup-
ply voltage and frequency corresponds to
the values of the air conditioner.
■ Check if amperage provided by the exter-
nal power supply is sufficient.
■ In order to prevent the power supply
extension cable to the vehicle from
overheating and loosing voltage please
unwind the cable drum completely.
■ The extension cable shall have min. 3 x
2,5 mm² cross section.
■ Ensure that the air outlet and intake
grilles are not covered by cloths, paper
or other objects.
■ Insert batteries into the remote control,
removing the cover on the back. Use 2
x 1,5V AAA LR3 batteries that will not
leak.
NOTE
■ When using the remote control point it
at the air distributor to ensure good sig-
nal transmission. The air distributor will
beep once a signal is received.
■ The symbols in the display of the remote
control are visible depending on the
settings.
■ Set the clock, see chapter 5.10.
■ After selecting the COOL or HEAT mode,
the compressor may delay starting for 3
minutes. This is a feature to protect the
compressor.
5.2 Achieving effective heating and cool-
ing
Many factors will affect the total heat load within the
vehicle and many factors can also affect the working
efficiency of the air conditioner. Before purchasing
Cool Top Trail air conditioners, the user shall consult
with the vehicle manufacturer to understand the total
heat load of the vehicle and to choose the correct air
conditioner for the application.
The following measures are very useful to reduce the
heat load within a vehicle and improve the perfor-
mance of the air conditioner.
■ Park the vehicle in the shade if possible.
■ Position the vehicle with the sunshade on the sun-
side. This will reduce the exposure to direct sun-
shine.
■ Close all doors, skylights and windows, close the
curtains and open the sunshade or awning.
■ Turn off unnecessary electrical appliances within the
vehicle to reduce the heat-load.
■ Cook outside the vehicle when possible.

■ In case of exceptionally high temperatures, turn on
the air-conditioner in advance during the morning.
■ If vehicle interior has heated up, ventilate your vehi-
cle by opening doors and windows before starting
the A/C unit.
■ Regularly clean the vehicle's roof because dirty roofs
heat up more.
5.3

Condensation

When warm, moist air within the vehicle meets with a
cold surface, condensation water may be formed. This
is also known as "sweating". In this case, take the fol-
lowing measures:
■ Close and seal all doors, skylights, and windows to
reduce the entrance of warm moist air.
■ Operate the inside fan on high fan speed, avoid low
and auto fan speeds.
During the operation of the air conditioner, conden-
sate water will be produced and allowed to drain onto
the roof. This is normal. The amount of condensate
water is a function of air humidity. High humidity in-
side the vehicle will result in more condensate water
being generated.
Please note that losses or damage caused by
condensate water are not within warranty scope.
5.4

Choosing and using a generator

The Cool Top Trail 20/24 requires a mains quality AC
power source for correct operation. If you decide to
supply power using a generator you must consult the
generator supplier to confirm suitability and sizing of
the generator for your application.
Please note that damages caused by the use of a
generator are not within warranty scope.
