Maintenance
There is a fluff filter (n) and a particle filter (p) on the front of
the device for cleaning the room air.

n
Fig. 4
The fluff filter (n) must be cleaned at regular intervals
(atleast 2 x per annum) and changed if required (part no.
40090-64600).
We recommend replacing the particle filter (p) every year at
the beginning of the season (part no. 40090-58100).
The cold air ducts must be removed before replacing the fil-
ters. Pull the fluff filter (n) a little way forward at the recesses
at the top edge and remove from above. Then remove particle
filter (p) from the front.
Fig. 5
When installing the particle filter (p) the printed arrows
must point towards the device – they indicate the circu-
lated air flow direction. Never operate the device without
filters. Operating the device without filters can cause evapo-
rator coil soiling, which can have a detrimental effect on the
performance of the device!
The condensation drain is under the floor of the vehicle. In
order to allow the condensation to drain away freely, check
whether the drain is free of dirt, leaves and the like at regular
intervals. Failure to do this may allow condensation to
penetrate the vehicle!
Troubleshooting
Is the motor home / caravan 230 V power supply lead prop-
erly connected, and are the fuses and circuit breakers OK?
Fault Cause / Remedy
Device not cooling – Thawing process in progress/
wait until thawing process is
complete.
– The temperature set on the
remote control has been
reached / set temperature on
remote control to less than
room temperature.
Device providing insuf-
ficient cooling or no
cooling at all
– Filters soiled / change filters.
– External air routes soiled,
blocked / clear air routes.
Moisture at cold air
ducts
– High air humidity / close win-
dows and doors and select high
fan level.
Remote control not
working
– Check batteries in remote
control / replace batteries if
necessary.
Device not reacting
to remote control
commands
– Check whether there are ob-
structions between the remote
control and the IR receiver / re-
move obstructions if necessary
– Is the remote control tuned to
the IR receiver? / tune remote
control to IR receiver
If these actions fail to remedy the fault, please contact Truma
Service.
IR remote control battery change
Only use micro-batteries that will not leak, type LR 3, AM4,
AAA, MN 2400 (1.5 V).
The battery compartment is on the rear of the remote control.
When inserting new batteries, make sure the positive / nega-
tive terminals are connected correctly!
Fig. 6
Empty, used batteries can leak and damage the remote
control! Remove the batteries if the remote control is
not being used for a long period of time.
The tuning between the remote control and the air con-
ditioning system is retained if the batteries are removed.
No warranty is given for damage caused by leaking
batteries.
