Important instructions
Repairs may only be carried out by properly qualified
professionals!
1. To avoid damage during transport, the device must only be
dispatched after discussion with the Truma Service department
(see page 54).
2. The voltage must be disconnected at all poles before the
housing is opened.
3. The 230 V, T 5 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.
4. Any modification to the device, or the use of spare parts
and functionally-important accessories which are not original
Truma components, or failure to respect the Installation and
Operating Instructions, will lead to the cancellation of the
guarantee and to the ex clusion of claims for liability.
5. The refrigerant circuit contains R 407c and R 134a refrigerant
and must only be opened by an expert
in the factory.
6. The cool air outflow and the ambient air suction intake must
not on any account be obstructed. Please bear this in mind in
order to ensure the trouble-free operation of your device.
7. 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.
8. If the floor of the vehicle is provided with
underfloor pro-
tection,
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
completed the covers can be removed again.
9. In order to avoid damage to the compressor, when the de-
vice is in operation during transit (for example, with the gene-
rator or voltage transformer working), do not attempt uphill or
downhill gradients of more than 8%.
10. 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.
11. 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.
12. When the floor of the vehicle is being cleaned, it must be
ensured that no water penetrates the openings in the base of
the unit when spraying with a high-pressure cleaner, for
example.
Notes for the use of air-conditioners
– The Saphir vario 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 (min. 4.4 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 tho-
roughly, 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
system is in operation.
If a single room such as a bedroom is being cooled with
600 W, the two outlets that are not required must be
closed, otherwise the entire vehicle will be cooled with 600 W.
