Symbols used
Installation and repair of the device may only be carried
out by properly qualified professionals.
Symbol indicates a possible hazard.
Comment including information and tips.
Safety instructions
Repairs may only be carried out by properly qualified
professionals!
In order to avoid transport damage, the unit may only be dis-
patched after consulting Domestic Service.
The voltage must be disconnected at all poles before the
housing is opened.
The 230 V, T 6.3 A H-type (slow, IEC 127) fuse in the unit can
be found on the electronic control unit and must always be
replaced with an identical fuse.
Appliance fuses and connection leads may only be replaced
by a properly qualified person.
Guarantee claims, warranty claims and acceptance of liability
will be ruled out in the event of the following:
– modifications to the unit (including accessories),
– failure to use original Truma parts as replacement parts and
accessories,
– failure to follow the installation and operating instructions.
It also becomes illegal to use the appliance, and in some
countries this even makes it illegal to use the vehicle.
The refrigerant circuit contains R 407C refrigerant and must
only be opened by an expert in the factory.
The air outlet and the circulating air intake must not be ob-
structed under any circumstances. Please bear this in mind in
order to ensure the trouble-free operation of your device.
The apertures beneath the vehicle floor must be kept free of
dirt and snow slush. The apertures must not be located within
the area subject to spray from the wheels or mudguards.
Splash protection must be provided if necessary.
If the floor of the vehicle is provided with underfloor protec-
tion, all the apertures beneath the vehicle must be covered in
order to prevent the spray created from penetrating the device
and causing malfunctions. Once the work has been complet-
ed the covers can be removed again.
In order to avoid damage to the compressor, when the device
is in operation during transit (for example, with the generator
or voltage transformer working), do not attempt uphill or
downhill gradients of more than 8 %.
Do not allow cooling operation to run for extended periods in
a tilted position, since the condensation water which forms
may not be able to run off, and in the worst scenario might
penetrate into the vehicle.
For problem-free operation and in order to avoid damage, the
supply voltage must always come from a source with a sine
wave curve (e.g. voltage converter, generator) and without
voltage spikes.
When the floor of the vehicle is being cleaned, it must be en-
sured that no water penetrates the openings in the base of the
unit when spraying with a high-pressure cleaner, for example.
For safety reasons, the unit may only be operated when it is
closed, as only then is there a guarantee of protection against
injury from moving parts. The strap on the electronics housing
must not be removed.
Notes for the use of air conditioners
– The Saphir comfort RC air conditioning unit is designed
for minimal power consumption. Nevertheless, you should
check before taking the system into operation whether the
camping site has adequate fuses (minimum 6 A).
– As far as possible, park your vehicle in the shade.
– Darkening the interior with window blinds and / or a roof
awning will reduce the penetration of radiant heat.
– Clean the roof of the vehicle regularly (dirty roofs heat up
more readily).
– Before operating the device, ventilate your vehicle thor-
oughly, in order to allow the hot air which builds up inside
to escape.
– Take care when putting up awnings or similar that there
are sufficient openings for the supply air to be discharged.
The opening for the hot discharge air should not be on the
intake side.
– To create a healthy environment on the inside of the vehicle,
the difference between the inside and outside temperatures
should not be selected as too great. During operation the
circulated air will be purified and dried. Due to the drying of
the moist, humid air, a pleasant environment will be created
inside even with slight temperature differences.
– Keep the doors and windows closed while the cooling sys-
tem is in operation.
– Full fan power at all three openings can only be achieved
when three cold air pipes are connected.
– The exhaust duct (part No. 40040-32500) may not be used.
– In heating mode, only set fan to “high” use for heating up
quickly. In continuous operation set fan to the “medium” or
“low” position.

Taking into operation
Before switching on, it is essential to make sure that the fuse
system for the power supply at the camp site is sufficient
(230 V / minimum 6 A).
In order to prevent the power cable for the caravan
from overheating (minimum cross-section 3 x 2.5 mm²)
the cable drum must be fully unwound.
To carry out the individual switching commands, the remote
control must always be pointed at the infrared receiver.
Before switching on for the first time, the remote control must
be paired with the IR receiver.
– Insert batteries in the remote control (note polarity)
– Symbol flashes

Maintenance
Located on the front side of the unit is a fluff filter (n) and a
particle filter (p) for cleaning the air in the room.
p
n
The fluff filter (n) must be cleaned at regular intervals, at least
twice a year, and replaced if necessary (part no. 40090-64600).
We recommend that the particle filter (p) be replaced annually
at the start of the season (part no. 40090-58100).
To change the filters, disconnect cold air ducts beforehand.
Pull fluff filter (n) forward slightly at recesses at upper edge
and remove from above. Then withdraw particle filter (p) from
the front.
The arrows printed on the particle filter (p) must point
towards the unit when the filter is installed – these indi-
cate the recirculated air flow direction. The device must
never be operated without the filter. Without a filter the
evaporator will become dirty, which in turn will impair the
performance of the device!
The condensation water drain is located beneath 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. If this is not done, there is a risk
of condensation water penetrating into the vehicle!
Troubleshooting
Is the motor home / caravan 230 V power supply lead
connected, and are the fuses and circuit breakers OK?
Fault Cause / Action
Unit not cooling – Defrost in progress / wait until
defrosting is completed.
– The temperature set on the re-
mote control has been reached/
set the temperature on the
remote control lower than the
room temperature.
Unit not heating – Defrost in progress (outside
temperature between 4 °C and
7 °C) / set fan lower.
– Outside temperature
below 4 °C.
Unit cooling insuffi-
ciently or not at all – Filter dirty / change filter.
– External airways dirty, blocked /
unblock airways.
Moisture on the cold air
pipes – High air humidity / close win- dows and doors and set the fan
level to high.
Remote control not
working – Check remote control batteries / replace batteries if necessary.
Unit not respond-
ing to remote control
commands
– Check for obstructions be-
tween remote control and IR
receiver / remove obstructions if
necessary.
– Is the remote control paired
with the IR receiver / pair re-
mote control to the IR receiver.
If this does not solve the problem, please contact the Dometic
Service.

LR 3, AM4, AAA, MN 2400 (1.5 V).
The battery compartment is located on the rear of the remote
control unit.
When fitting new batteries, ensure the polarity (positive /
negative) is correct!
Dead and used batteries may leak and damage the
remote control unit. Remove the batteries if the remote
control is not going to be used for an extended period.
No claims under guarantee will be considered for
damage caused by leaking batteries.
Disposal
Before disposing of a defective remote control, it is essential
that the batteries be removed and disposed of in a proper
manner.
The device must be disposed of in line with the administra-
tive regulations of the respective country in which it is used.

In order to achieve homogeneous vehicle cooling, the
air conditioning unit must be installed in a central loca-
tion in a false floor or the like so that the cold air is evenly
distributed.
The air conditioning unit is attached to the floor, which must
be level and smooth. If necessary, in, for example, uneven
ground, the air inlet (LE), air outlet (LA) and connectors (11)
can be fitted with additional seals.
Installation instructions The air that is to be cooled is drawn in again by the unit from
the vehicle interior through openings with a total area of at
least 300 cm².
The circulated air will be purified and dried while the
unit is in operation. Accordingly, if the unit is installed
in external stowage containers (e.g. double bottoms) suitable
steps must be taken to ensure that the air which is to be
cooled is extracted from the interior of the vehicle. The suc-
tion intake of air from the outside can severely impair the ef-
fect of the air conditioning system.
If possible, position the unit so that the frame of the vehicle is
between the air inlet (LE) and the air outlet (LA).
Place the installation template into the stowage box that is
intended for installation and check the space situation for the
floor openings. The air conditioning unit should have at least
20 mm of clearance at the sides and 30 mm at the rear from
walls and any furniture items in order to prevent noise trans-
mission during operation. The minimum clearance at the front
is 200 mm, so that the fluff / particle filter can be changed.
The openings in the floor of the vehicle must be freely
accessible, and must not be blocked by frame sections
behind them or the like! The openings must not be within the
range of the wheel spray. Spray guards must be fitted if
necessary.
Installing the air conditioning system
Place installation template in stowage compartment and fix in
position.
Mark fastening holes for the 2 retaining brackets (2 – HW)
and the 2 fastening brackets (3) at the sides.

Remove template and cut out the marked floor openings.
Before drilling, always check for underlying / concealed
cables, gas lines, frame sections and the like!
Then seal the edges of the openings in the floor of the vehicle
with underfloor protection.
Screw down each of the 2 side fastening brackets (3) with
2 screws and each of the 2 retaining brackets (2 – HW –
leg must be on the outside!) with 3 screws.
Insert the connectors (11) for draining condensate (KO) from
above.

Seal the circumference of connectors (11) for draining con-
densate from below with automotive body sealant.
When installing the unit, it is vital to ensure that
the connectors (11) to the condensate drainage are
located in the recess at the bottom of the device. Oth-
erwise there is a risk of water penetrating the interior!
In order to provide good air circulation, the openings in
the bottom of the unit and the floor must align exactly.
Correct operation of the unit cannot be guaranteed un-
less this is the case!

between the retaining brackets (2 – HW) and the fastening
brackets (3). Secure air conditioning unit using the tension
strap (4). Ensure that the tension strap is inserted in the re-
cesses provided on the unit. Guide tension strap (4) through
the clasp (6) as shown in the illustration and tighten.
The air conditioning unit must be attached at all sides
using the brackets provided in order to prevent unin-
tentional movement if vigorous movements occur (e.g. hard
braking).
Attach the two floor grilles (5) for “LE” and “LA” to the floor
of the vehicle from below with suitable screws or clips (not
provided).
Cold air distribution and circulating air
return feed
Air distribution
The same pipework (cold air pipes) are used in heating /
cooling mode.
A KR 65 Ø 65 mm (10) cold air duct with at least one outlet
must be connected to each of the three cold air emitters of
the unit (7, 8 and 9).
Slide the cold air ducts (10) into the cold air outlets of the unit
and route to the air outlet nozzles. Ensure that the cold air
ducts are firmly seated in the cold air outlets. Truma can
supply a sound muffler for installing in the cold air system
(part no. 40040-60100) as an accessory for reducing the
noise level.
Suitable vents for air in the passenger compartment are the
SCW 2 swivelling nozzles (black – part no. 39971-01 or beige,
part no. 39971-02), end piece EN-O (part no. 40171-07) with
lamella inset LA (part no. 40721-01/02/03/04/05) or the RL
rectangular air outlet (part no. 40280-01) with the ANH con-
necting piece (part no. 40290-02) have proven to be suitable
for emitting the cooled air into the interior of the vehicle.
Important notes
The cold air distribution system is individually designed for
each vehicle model using a modular principle. A wide range
of accessories is available for this purpose.
In order to achieve the best possible cooling power, we
recommend:
– Route cold air pipes to air vents as short and straight as
possible.
– The total accumulated length of cold air duct that may be
used is 15 m.
– Connect the longest cold air pipe (max. 8 m) to the
right-hand cold air outlet (9), since this has the most air
throughput.
– To prevent condensation in the cold air ducts, do not route
pipes anywhere near heat sources (e.g. power supplies or
behind the refrigerator).
Circulating air return
The circulating air is drawn in again by the unit, either through
an additional rectangular air grille (1 – part no. 40040-29200)
or 3 round air grilles (part no. 40040-20400), e.g. in the stow-
age box wall or via several smaller openings with a total area
of at least 300 cm².
Important note
To ensure trouble-free air exchange, the air infeed from the in-
terior of the vehicle to the installation location must be located
in the immediate vicinity of the device. If appropriate, covers
are to be fitted, in order to avoid the circulating air return be-
ing impeded by stowed objects.
If the equipment cannot be installed in close proximity,
Truma can provide a flexible air intake (part no. 40090-
59100) as an accessory.

Installing the IR receiver
The receiver (12) is to be fitted for preference on the clothes
cabinet in such a way that the remote control can be pointed
at it without any hinderance (length of connection cable 3 m).
If necessary, a 3 metre cable extension can be supplied
(part no. 40090-89100).
If the receiver cannot be flush-mounted, Truma can
provide an on-surface frame (13) – part no. 40000-52600
as an accessory if required.
Drill Ø 55 mm hole. Lead IR receiver cable (17) through
towards the rear and secure receiver with 4 screws (14 –
not provided). Then clip on the cover frame (15) and route
cable (17) to air conditioning unit.

Truma will supply side parts (16) in 8 different colours for
finishing off the cover frames (please contact your dealer
for details).
230 V electrical connection and
IR receiver connection
The 230 V electrical connection must always be made
by an expert (in accordance with VDE 0100, part 721 or
IEC 60364-7-721, for example, in Germany). The instructions
given here are not a challenge to the lay person to carry out
the electrical connection, but serve to provide additional infor-
mation for the professional fitter whom you engage!
Establish the connection to the mains with the connection
cable (20), 150 cm long, to a lead in the vehicle, fused to at
least 10 A.
It is essential to ensure the correct cable colours are connected!

Insert plug of IR receiver cable (17) into socket (19).
The port (18) is a com port for communication and is not
required for operating the equipment.
The cables must be long enough for the unit to be pulled out
of the false floor with the cables attached. All cables must be
secured with cable clips!
For maintenance or repair work, an isolating device must be
provided on the vehicle side to provide all-pole isolation from
the mains, with a contact interval of at least 3.5 mm.
Function test / Mounting for the remote
control
Position IR remote handset cradle as close as possible to the
IR receiver (12) so that the air conditioning unit can be oper-
ated without removing the remote handset from the cradle.
In conclusion, all the functions of the device need to be tested
in accordance with the Operating Instructions.
The operating instructions must be handed to the owner of
the vehicle.

In Australia, always notify the Dometic Service Centre
if problems are encountered; in other countries the
relevant service partners should be contacted
(see Service Booklet or www.truma.com).
Having the equipment model and the serial number
ready (see type plate) will speed up processing.
