The following measures are very useful to reduce the heat load within a vehicle and improve the performance of the air conditioner.
unwind the cable drum completely.
Park the vehicle in the shade if possible.
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.
Position the vehicle with the sunshade on the sunside. This will reduce the
exposure to direct sunshine.
Close all doors, skylights and windows, close the curtains and open the
sunshade or awning.
Insert batteries into the remote control, removing the cover on the back. Use
2 x 1,5V AAA LR3 batteries that will not leak.
When using the remote control point it at the air distributor to ensure good
signal 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.
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 vehicle by opening doors and
windows before starting the A/C unit.
Regularly clean the vehicle’s roof because dirty roofs heat up more.
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.
Cool Top Trail 34

More information https://www.caravansplus.com.au
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 following 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, condensate 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 34 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.

6 Maintenance
6.1 Filter 1
Fig. 43: Air filter
The return air filter needs periodic maintenance.
X Check and clean the filters each week when in use to prevent the filters
from being blocked by dirt.
X The filters should be washed frequently to ensure effective cooling and
heating.
X Pull out the filter assembly from the air distributor by pushing both tabs
inwards and then downwards.
X Lift the filter (1) upward and pull out of the air grille (2) along the
tracks.
X Clean the filter and air grille with warm water and detergent.
2 X Let it dry before installing again.
NOTE Replacement filters can be ordered separately. Never operate the air
conditioner without a fil-
ter. This can cause fouling of the heat exchanger and lead to a loss of power.
6.2 Batteries of the remote control Fig. 44: Remote control battery change
Change the remote control batteries (2xAAA type) when the display of the
remote control becomes unreadable and/or blurry.
Do not dispose of any batteries with general household waste. Return defective
or used batteries to your retailer or dispose of them at a collection point.
NOTE Remove the batteries from the remote control if the remote control is not
used for a long time to prevent damage to the remote control from leaking
batteries.
6.3 Bolt check X Check the four bolts holding the unit to the roof for
tightness 3 months after the first installation of the prod-
uct. X Inspect these bolt regularly every 12 months. Retighten to 11 Nm if
necessary.
6.4 Regular usage It is recommended that the air conditioner is operated
regularly to ensure good performance. X Run the unit at least for 20-30 min.
every 6 months.
6.5 Cleaning X Regularly remove leaves or other dirt from the ventilation
grilles of the outdoor unit. X Regularly clean the unit with a soft, damp
cloth and mild detergent. X Clean the vehicle roof at regular intervals. A
dirty roof heats up more than a clean roof.

CAUTION
Never drive through automatic car washes with a roof air conditioner
installed. Do not spray into the openings of the unit with a high-pressure
cleaner. Do not use hot cleaners and steam cleaners. Do not use sharp or hard
objects for cleaning. Never use petrol, diesel, solvents or agressive cleaning
agents.
6.6 Heat exchangers Once per year have the heat exchangers cleaned by a specialist workshop.
7 Troubleshooting guide
Symptom
No air distributor display when unit turned ON.
Cooling not available.
Heating not available.
Poor cooling capacity.
Water dripping out of air distributor
Fault codes displayed on the panel:
E0 E1 E2 E3 E4
Remedy
X Check whether: the power is supplied to the vehicle and circuit breakers
are on. the remote control battery is OK. the remote control is off. the
voltage is too low. the amperage of the circuit breaker in the external
power supply is too low.
X Check that the cooling mode is selected and the air distributor display
shows . X Use the remote control to set required temperature below the current
room tem-
perature. The compressor will delay a re-start for three minutes. X Check that
the heating mode is selected and the air distributor display shows . X Use the
remote control to set required temperature above the current room tem-
perature. More time would be needed for starting heating under extremely cold
condition. When the unit is in heating mode and the outside temperature is
very low the unit may automatically enter defrost mode. The heating will
temporarily stop as the unit warms the outside heat exchanger to remove any
frost & ice. Heating will resume once the outside heat exchanger has been
cleared. During defrost the unit will display “dF”. X Make sure the filter is
clean. X Increase the fan speed to high to obtain the maximum capacity. X Make
sure all the doors and windows as well as the sunroof are closed. X Use
curtains and awnings to decrease the heat load. X Check that the air openings
of outdoor unit are not soiled or blocked. X Unblock condensate outlets of
outdoor unit. X Check seal of the adaptor frame. X Park the vehicle in a more
horizontal position, with an angle < 5° (8,8%). X Increase the fan speed to
high if condensate forms on the outside of the air dis-
tributor.
In case there is “0” or a jumbled display while on generator supply this may
indicate unstable voltage and current. Communication fault. Room temperature
sensor fault. Indoor heat exchanger temperature sensor fault. Outdoor heat
exchanger temperature sensor fault. No cooling effect. Possible root causes
are:
Insufficient refrigerant amount due to piping fracture. Compressor fault.
Sensor failure.

Symptom
E5
dF
Remedy
Outdoor heat exchanger temperature too high / Temperature anomaly.
Temperature anomaly: outdoor heat exchanger temperature too high when cooling
or too low when heating. (When cooling, the display of E5 indicates the
outdoor temperature exceeds 68°C. It is likely due to the reduction of air
flow of the condenser, poor working of the condenser fan or sensor failure;
when heating, if the outdoor temperature is higher than 18°C, the external air
fan may be on and off repeatedly. The occurrence of this is not a fault, but
the self protection of the system to avoid overheating of the unit.) Not a
fault: When operating on heating mode in low ambient temperatures the unit
will periodically defrost the outside heat exchanger. The air distributor
display shows “dF” during defrost operation and then returns to heating once
the defrost is completed.
NOTE Before contacting Webasto for technical support please collect the
following information: Are any error codes displayed? Is the display of the
air distributor in normal operation or not? Does it display a temperature from
16 to 30°C? Can you adjust the set point temperature when in cool or heat
mode? Is there a “0” shown in the display? Is the display showing a jumbled
display? When in fan mode is there any air flow from the air distributor
outlets? Can you hear the compressor starting or stopping in heating or
cooling mode? Your help in collecting this information will greatly assist the
service team in correcting any problems. Thank you.
