Installation
instructions
Please fold out the
illustrations page!
Installation and repair of
the device may only be
carried out by properly
qualified professionals.
Before staring work, read the
Installation Instructions thor-
oughly and follow them care-
fully!
Fig A shows the minimum
installation dimensions for
standard installation. The di-
mension „B - 50 mm” is the
minimum distance for ade-
quate air intake.
When the retrofitted particle
filter is used, the minimum
distance is 85 mm.

alternative air supply (LE).
Purpose
This device was designed for
installation inside mobile
homes and caravans. Any
other applications are only
possible after consultation
with Truma.
Approval
Declaration of conformity:
The Truma-Frostair 1700 air
conditioner meets the basic
requirements of EN 814-1, the
technical safety and environ-
mentally-relevant require-
ments of EN 378-1, the EMV
Directive 89/336/EEC, the
Low-Voltage Directive
73/23/EEC, and the other joint-
ly applicable EC Directives,
and is entitled to bear the CE
marking.
EEC Type Approval:
e1 022801
Other Provisions
Any modification to the device,
or the use of spare parts and
functionally-important acces-
sories 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 exclusion
of claims for liability. In addi-
tion to this, the operational
approval for the device will
be cancelled.
Location selection
The device is in principle to
be installed in such a way
that it is readily accessible at
all times for servicing work,
and can be easily removed
and installed.
In order to achieve uni-
form cooling of the ve-
hicle, the air-conditioning unit
must be installed centrally in
a stowage box or similar
mounting in such a way that
the air distribution pipes can
be laid vertically in covered
areas (e.g. in clothes cup-
boards).
The air-conditioning unit is
mounted on the floor. The
room air which is to be cooled
is drawn in directly by the
device via an additional air
grille in the stowage box wall
(1 - Special Accessory Art. no.
40040-29200) or via other
apertures with a total surface
area of at least 300 cm
2
.
The circulated air will
be purified and dried
while the unit is in operation.
Accordingly, if the unit is in-
stalled in external stowage
containers (e.g. double bot-
toms) suitable steps must be
taken to ensure that the air
which is to be cooled is ex-
tracted from the interior of
the vehicle. The suction in-
take of air from the outside
can severely impair the effect
of the air-conditioning sys-
tem.
1. Place the installation tem-
plate provided into the
stowage compartment in
which it is intended to install
the device, and check the
spatial conditions for the floor
apertures.
The apertures in the
vehicle floor must be
freely accessible, and must
not be covered by any frame
elements or similar objects
located behind them.
2. After checking the spatial
conditions, align the installa-
tion template, fix it in position
with adhesive tape, and mark
out the floor or side wall
apertures „LE“ for the supply
air infeed, in accordance with
the spatial circumstances.
Standard supply air
intake
As standard the supply air in-
take is effected through the
floor of the vehicle (Fig. B - LE).
In the case of a caravan, the
appliance must be placed in
such a way that the vehicle
frame is located between the
suction intake aperture and
the waste air outlet.
Alternative supply air
intake
If the floor cut-out (LE)
comes up against an obstacle
(such as the vehicle frame),
as an alternative the supply
air can be introduced either
via a suction channel (Fig. C -
Special Accessory Art. no.
40040-24700) or by means of
a flexible intake pipe, max.
1 metre long (Special Acces-
sory Art. no. 40040-29400)
through the side wall of the
vehicle (Fig. D) or though the
floor (Fig. E).
The alternative supply air in-
take can be connected op-
tionally to the right, left, or
rear face of the appliance.
The supply air outlet (LA)
is always passed through
the floor of the vehicle.
Fitting alternative
supply air
Suction channel
1. Insert the installation tem-
plate provided with the suc-
tion channel element
(Fig. C: 2) on the preselected
side of the appliance tem-
plate in such a way that the
arrows point at one another.
2. Make hole in floor (using
installation template) and
then apply underbody protec-
tion to the edges of the
openings in the floor of the
vehicle.
Before starting any drilling,
always ensure that there
are no cables, gas lines,
frame sections, or similar
items located or concealed
behind the drilling area!
3. Unscrew the cover on the
appliance (3 - rear or side)
and secure the suction chan-
nel (2) to the appliance with
the screws provided.
The suction channel (2)
should not be addition-
ally screwed to the vehicle
floor, since this may cause
running noise to be trans-
ferred to the vehicle with
unfavourable results.
Flexible supply air
intake
In order to avoid the un-
intentional penetration
of water, in particular when
the vehicle is being washed,
the feed pipe must be fitted
so as to descend from the
device to the side wall of the
vehicle.
1. If necessary, offer up the
air-conditioning device in the
installation space, and mark
the apertures on the side wall
and floor of the vehicle.
2. Remove the air condition-
ing unit again and cut out the
opening to a diameter of
162 mm. Then seal the edges
of the openings in the floor of
the vehicle with underbody
protection.
Before starting any drilling,
always ensure that there
are no cables, gas lines,
frame sections, or similar
items located or concealed
behind the drilling area!
3. Unscrew the cover on the
device (3 - rear or side) and
secure the suction flange (4)
to the device with the screws
provided.
4. Coat the air suction hose
(5 - max. length 1 m) on one
of its sides with permanently-
elastic bodywork sealant (no
silicone), and screw it into
the flange on the outside
grille (6). Guide both ele-
ments together through the
aperture from the outside,
and screw them firmly into
the device (the hose can be
shortened if necessary), until
the outside grille (6) is flush
with the outside wall.
5. Coat the outside grille (6)
with permanently elastic
bodywork sealant likewise
(no silicone) and secure it
with 4 screws (7).
Installing the air-
conditioning unit
1. After selecting the supply
air infeed, mark out the se-
curing points for the retaining
bracket (HW) and the lateral
securing brackets (9) for the
tensioning bands (8).
The retaining bracket
(HW) must be secured
in front of the air-condi-
tioning unit, seen in the di-
rection of travel, in order to
avoid inadvertent slippage in
the event of violent move-
ments (e.g. sharp braking).
