7. The apertures beneath the
vehicle floor must be kept
free of dirt and snow slush.
The apertures must not be lo-
cated within the area subject
to spray from the wheels or
mudguards. Splash protec-
tion must be provided if nec-
essary.
8. If the floor of the vehicle is
provided with underfloor pro-
tection, all the apertures be-
neath the vehicle must be cov-
ered in order to prevent the
spray created from penetrating
the device and causing mal-
functions. 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 tran-
sit (for example, with the gen-
erator or voltage transformer
working), do not attempt uphill
or downhill gradients of more
than 8%.
10. Do not allow cooling op-
eration 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.
Maintenance
Located on the front face of
the device is a flow filter for
the suction intake of the sur-
rounding air (Page C, Fig. B,
Pos. 24). This must be
cleaned at regular intervals,
at least twice a year, and
replaced if necessary.
The appliance must
never be operated
without the flow filter. With-
out a filter the evaporator may
become contaminated with
dirt, which in turn will impair
the performance of the system.
The condensation water drain
is located beneath the floor of
the vehicle (Page C, Fig. B,
Pos. 11). In order for the con-
densation water to drain away
freely, a regular check should
be made to ensure that the
drain hose is free of dirt, veg-
etation residue, or similar ob-
structions. If this is not done,
there is a risk of condensa-
tion water penetrating into
the vehicle!
Trouble-shooting
In the event of a fault, you
should in principle contact
Truma Service (see page 44).
Before calling Customer
Service, please check the
following:
1. Is the 230 V mobile home
supply properly connected,
and are the fuses and protec-
tive switch in good order?
2. Is the temperature which
has been set on the remote
control less than the interior
temperature?
3. Are the fluff filter on the
unit (Page C, Fig. B, Pos. 24)
and the air intake to the
stowage box (Pos. 1) in
which the device is installed
free?
4. Is the aperture for the sup-
ply air in the floor of the vehi-
cle or the side wall free of
dirt, foliage, or other obstruc-
tions?
Changing the battery
in the remote control
Please be sure to use leak-
proof micro-batteries only,
type 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 batter-
ies may leak and dam-
age the remote control unit!
Remove the batteries if the
remote control is not going to
be used for an extended peri-
od.
No claims under guaran-
tee will be considered for
damage caused by leaking
batteries.
Before throwing away a de-
fective remote control, it is
essential that the batteries be
removed and disposed of in
the proper manner.
Accessories
If desired, Truma can supply
a particle filter for purification
of the interior air.
Subsequent fitting set,
particle filter, complete with
mounting frame
(Art. no. 40040-23600).
Replacement particle filter
(Art. no. 40040-23100).
If a securing bracket (1)
is fitted in front of the
air-conditioning unit, the air-
conditioning unit will have to
be partially dismantled in or-
der to instal the subsequent
fitting set, and the bracket re-
located by about 6 mm.
Changing the filter
Remove the old, dirty filter by
lifting it out upwards. Intro-
duce the new filter into the
guide rails from above, and
push it down firmly.
Noise suppressor for installa-
tion in the cold air pipe for
additional noise reduction
within the living compart-
ment (Art. no. 40040-60100).
Blow-out channel for addi-
tional noise reduction outside
the living compartment.
Installed beneath the vehicle
(Art. no. 40040-32500).
Notes for the use
of air-conditioners
- The Truma Frostair 1700 is
designed for minimal current
consumption. Nevertheless,
you should check before tak-
ing the system into operation
whether the camping site has
adequate fuses (minimum 3 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 pene-
tration of radiant heat.
- Clean the roof of the vehi-
cle regularly (dirty roofs heat
up more readily).
- Before operating the de-
vice, ventilate your vehicle
thoroughly, in order to allow
the hot air which builds up in-
side to escape.
- Take care when putting up
awnings or similar that there
are sufficient openings for
the supply air to be dis-
charged. The opening for the
hot discharge air should not
be on the intake side.
- To create a healthy environ-
ment on the inside of the ve-
hicle, the difference between
the inside and outside tem-
peratures should not be se-
lected 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 tem-
perature differences.
- Keep the doors and win-
dows closed while the cool-
ing system is in operation.
