1 General instructions and operating principle
The AUTOTERM AIR heaters are designed to be used:
•for heating of various confined spaces, of vehicles for example driver’s cabin
or cargo compartment of vans or trucks at ambient temperatures up to -45°C.;
•for heating cabins, cargo compartments and other various confined spaces of
maritime transport;
The heater operates independently of the vehicle engine.
Heaters built-in fan draws air through the air intake opening. The air heated by the
heater is channelled to cabins and desired spaces via outlet channels.
Fuel is supplied by a separate fuel pump from the fuel tank of the vehicle or vessel or
from an additional fuel tank.
The heater can be powered by a battery of the vehicle or a separate battery.
Temperature in rooms can be regulated by using a temperature sensor and a control
panel, which sets heating parameters.
When a temperature sensoris present (either built in to the control panel or additionally
installed), the heateris constantlycomparing the actual temperature with the set temperature
and automatically adjusts the heating capacity according to the heat demand
Installation of the heater and its components must be carried out by
specialized organizations approved by AUTOTERM. Installation of the
heater must be carried out only by certified specialists in accordance
with the installation instructions.
If the heater is handled and/or installed improperly, there is a possibility
of a fire hazard and damage of property because fuel and electrical
components are being used. That is why all safety precautions and
installation instructions must be observed.
Basic parameters and specifications of the heaters can be found at the end of this manual
(see Annex 1).

2 Safety precautions
•Do not use or install the heater in places, where flammable vapors or
gases or large amounts of dust may form and accumulate.
•Disable the heater, when the vehicle or vessel is being fueled.
•Do not cover the heater with clothing, pieces of fabric and so on, and
do not place such objects in front of the air intake pipe or inlet and
output of the heated air.
•Do not install the fuel line inside the cabin of a vehicle.
•The installation arrangement must exclude the possibility of
contact of the exhaust pipe with the air intake, fuel pipe, or other
flammable objects.
•The vehicle where the heater is installed must be equipped with a fire
extinguisher.
•Do not install electric wiring (harnesses) of the heater near the fuel
line and the exhaust pipe.
•Disconnect the heater from its battery during repair works on the
heater.
•Do not connect the heater to the power circuit of the vessel, when the

•Do not connect or disconnect connectors ofthe heater, when theheater
is powered.
•When electric welding is carried out on the vehicle, or repair work is
made on the heater, the heater must be disconnected from the battery.
•Do not use fuses rated differently from indicated on the electric circuit
diagram.
•Do not use makeshift devices (wires etc.) instead of fuses.
•Take the safety precautions, which must be observed when working
with an electrical and fuel systems, when installing and dismantling
the heater.
•Do not disconnect the heater from power before the purge cycle
ends.
•When the heater has been switched off, do not switch it on again for
5-10 seconds.
•Do not step on the heater or put any objects on it and in it.
•Electric wiring, theair intake, and the fuel pipe must be protected
from contact with sharp edges of vehicle structures.
•For safety reasons, contact the service shop to troubleshoot the heater
if it fails to launch two times in a row.
•In case of faults in the operation of the heater, contact specialized
repair organizations authorized by AUTOTERM.
If the consumer fails to follow the requirements above, the warranty of the heater
becomes null and void.

Retrofitting
For replacing different brand of heater for an AUTOTERM AIR heater, following
things must to be checked first:
Diameter of exhaust pipe.
The AIR-2D and AIR-4D have an exhaust pipe with an internal diameter of 24mm and
AIR-8D and AIR-9D have an exhaust pipe with an internal diameter of 38mm.
Some brands use different diameter exhaust pipes, if so, it needs to be changed to
necessary diameter suitable for the heater in use. Larger diameters can be used, if needed.
(see “Section 3.3”, for more information on installing the exhaust pipe).
Disregard of this advice can lead to insufficient output of exhaust gases due
to backpressure, thus damaging the heater.
Fuel system.
When retrofitting a heater, all old fuel pipes and fuel pumps must be removed
completely and suitable fuel system for AUTOTERM AIR heater must be installed instead.
Different brands of fuel pumps can have different fuel output and fuel pipes can be in
different diameter. (see “Section 3.4”, for more information on installing the fuel system).
Disregard of this advice can cause fuel overflow in the heater or insufficient
flow of fuel, thus damaging the heater.
Electrical wiring.
All old wiring, electrical connections, control panels, etc. must be removed and
installed with new AUTOTERM AIR suitable components. (see “Section 3.5”, for more
information on installing the wiring of the heater).
Electrical related faults are common when using different and unsuitable
electrical components.
Diameter of air ducts.
At least 60mm air duct must be used for AIR-2D, at least 90mm air duct for AIR-4D,
and at least 100mm for AIR-9D. If the existing air duct is smaller in diameter, then
everything must be changed up to the first branch with the necessary diameter and as well
as the first hot air outlet. After that the size of air duct can be decreased using different
adapters (see “Section 5”, for more information on air ducting).
Disregard of this advice can cause the heater to overheat, thus damaging it.
DO NOT connect air ducts to AIR-8D.

3 Main requirements of installation of assemblies and units of the heater
Heater can be installed both inside, and outside of the vehicle. Install the heater in a
dry place that is protected from ingress of water and condensate, dirt, excessive vibrations
and heat emissions, engine emissions or fuel or oil contamination.
Installing the heater on a maritime transport it must be protected from
ingress of overboard water.
Consider the maximum heel of the vessel. A heel must not bring overboard
water into the discharge channel for exhaust gases, and bilge or overboard
water must not get on the heater.
Installing the heater in a cargo hold of the vehicle, install the heater at a
height and location that prevents contact with cargo and in a way that the
cargo would not obstruct the intake/outlet of the heater.
The heater must be installed following safety requirements and taking into account the
type of vehicle or vessel. Consider everything related to peripheral equipment, for example,
the maximum permissible length of the exhaust gas channel and intake of air for
combustion, the location of the passage in the board (for maritime transport), the layout and
length of electric wires, distance from the fuel tank, layout of air ducts of warm air, intake
of fresh air.
All precautions must be observed when installing the heater to reduce the risk of
injuries to personnel or damage to the equipment as much as possible.

8
3.1 Installation of the heater
Install the heater, taking into consideration permissible operating position according
to Fig.1a/b. Take into account the possible heel of the vessel, if installing on a maritime
transport.
When heater is positioned with exhaust pipe facing downwards and air inlet facing
towards you, it is considered 0° position. AIR-2D and AIR-4D can be tilted everything
between 0 and 90°. From the same point of view, wires on the 2D and 4D must remain on
the right side or on the top of the heater. The AIR-8D and AIR-9D should not be tilted
(see Fig.1a).
WARNING!!! Reliable operation of the heater depends on correct
installation of the heater. The heater must be installed horizontally
(according to Fig.1a).

Fig. 1b –Distance from walls
The distance from surrounding objects must be sufficient to ensure good ventilation.
The distance from walls and partitions to the start of the inlet opening of the heater must be
no less than 50mm for AIR-2D/4D and 100mm for AIR-8D/9D (see Fig.1b). The distance
from walls, partitions to the start of the outlet opening of the heater must be no less than
150mm for AIR-2D/4D and 250mm for AIR-8D/9D. Provide protection from penetration
of foreign objects into intake and output openings, when installing and operating the heater.
Install the heater so that it is convenient to do maintenance works.
For installing air ducts, these distances need to be considerably greater (see “Section 5”,
for more information on air ducting).
DO NOT install near flammable or heat-sensitive objects such as sails,
fenders, clothing, sheets, paper, gas pipelines, fuel tanks, etc.
When installing the heater, make sure that the mounting flange is the only place of
contact with the mounting surface of the vehicle or vessel. The casing of the heater should
not contact any surface (Fig.2b), to avoid deformation of the heater casing, jamming of
the air blower fan and potential overheating.
Install the heater on a flat surface, because installing on uneven surface,
can bend the casing of the heater, thus blocking the fan (common cause of
error 27).
AIR-2D, AIR-4D
AIR-8D, AIR-9D

10
It is recommended to use an appropriate
mounting bracket specific for desired
mounting location (variety of mounting
brackets canbe purchased at your local dealer)
and the rubber seal (seen in Fig. 2) for the
installation surface of the heater, when
installing the heater.
In case the heater is installed in a large
passenger van or a bus, it may be installed
without using mounting brackets.
In case the heater is installed onto a
pedestal or a mounting bracket, cover the air
intake, exhaust pipe, and the fuel pipe areas
with a metal cover.
Fig. 2b - Leave some free space
For heaters AUTOTERM AIR-2D and AIR-4D, holes in the body of the vehicle
should be made as shown in Fig.3. Heater can be installed using mounting plates shown on
Fig. 2. In this case studs provided with heater must be replaced with longer studs.

Cut the opening inside the vehicle body (in case the side wall/floor is not thicker than
3 mm) for AIR-8D heater installation as shown on Fig. 3. With the thickness of the vehicle
body (floor) of more than 3mm, installation of the heater requires the following:
1. Cut a rectangular hole in the vehicle body sized 180×95 mm
2. To attach the mounting bracket* to the heater (this bracket can be made of steel
sheet at least 2.5mm thick);
3. Install the exhaust pipe, air intake, and fuel line to the heater and fasten the
whole assembly to the body of the vehicle
*—optional part
3.2 Installation of the air intake pipe.
The air for combustion must not be taken
from the interior, living space, engine or luggage
compartment of the vehicle or vessel. Air should
be taken from well-ventilated areas or from outside
of the vehicle or vessel.
The maximum length of the air intake pipe is 2
meters. The air pipe must be as short as possible (cut
to the necessary length).
It is forbidden to use the heater without
an air intake pipe.
The air intake pipe is connected
directly to the pipe of the heater and
fastened with a clamp. (Fig.4).
When laying the air intake pipe, avoid
sharp bends and do not obstruct the
opening of the air intake pipe with
foreign objects. Make sure its opening
is pointing downwards (see Fig. 5). If
that is not possible Ø3mm hole needs to be drilled at the lowest point of the pipe.
The correct installation of the exhaust and air intake pipes is when they are on the same
side (Fig.6a/b). The distance between them should exclude re-suction of exhaust gases
through the air intake (at least 20 cm).

Disregard of this recommendation can lead to the opposite movement
of the flame towards the air pump fan, to melting of air pump fan and
to burning of a heater.
Air intake must not be installed in the movement direction of the
vehicle/vessel.
In cases when intake of clean air cannot be ensured, such as off-road
and special purpose vehicles, please mount the dedicated
AUTOTERM air filter (assy.2684)
3.2.1 Installation of the air intake pipe on maritime transport
Air intake from well-ventilated areas
Ambient pressure and sufficient ventilation using outside air must be present in the air
intake zone. Increased or reduced pressure in the air intake zones is not allowed. It is
recommended to attach the air duct all along its length to the hull of the vessel using plastic
clamps, when possible. Put a cap on the end of the air duct to protect it from drawing in
foreign objects.
Air intake from outside of the vessel.
An air intake pipe (Fig.7) should be used to take the air from outside Make an opening
Ø26+1 mm in the board of the vessel to install it. Install a rubber gasket between the flange
of the air intake pipe and the hull of the vessel. Attach the air duct using three bolts as shown
on Fig.7. Attach the air duct to the air intake pipe using the clamp. It is recommended to
attach the air duct all along its length to elements of the hull of the vessel using plastic tie
straps, when possible. Make a 3mm opening in the bottom point of the air duct to drain
condensate or any water, which has penetrated the air intake pipe.

13
Do not place the intake opening of the air intake pipe in front of
the incoming air flow of the moving vessel

3.3 Installation of the exhaust pipe.
When installing the exhaust pipe, take into
consideration high temperature (up to 500°С) of the
exhaust pipe when heater is in operation. Cut the exhaust
pipe (flexible crinkled metal hose, maximum length –2
meters) to the necessary length. It is advised to use two-
layer exhaust pipe when installing the heater. Attach the
exhaust pipe (Fig.8) using clamps and install it so that it is
slightly inclined to the bottom in the direction of exhaust.
Install heat insulation on the exhaust pipe to protect
individual sections of the vessel (wiring or other heat-
sensitive objects).
Fig. 8 - Attachment of the metal pipe to
the heater
Install the exhaust pipe to avoid the possibilityof repeated intake of exhaust
gases by the air intake pipe, and make sure that no exhaust gases enter the
interior or are drawn in by the fan through the cab heater radiator.
At the end of the exhaust pipe a shield is installed, which necessary for stable
operation at low heating modes (Fig.9).

Metal exhaust pipe

14
In absence of the shield, air will be blown back into
the exhaust pipe. This leads to increased heater shooting
and impairs heat capacity. Exhaust gases must be
removed outside of the vehicle
Heater is provided with airtight exhaust silencer.
This mean it can be mounted in small vessels and
confined spaces. But for mounting exhaust silencer on
theoutside of the vehicle, Ø5mm hole needs to be drilled
at the bottom of the silencer (see Fig. 10a).
If desired mounting situation requires the exhaust
silencer to be mounted vertically, condensate drain hole
must be drilled, like shown in Fig. 10b, to avoid
condensate build up in exhaust silencer. If that is not
possible, it is recommended to install it sideways (see
Fig.10a).
The outlet of the exhaust pipe must be installed
pointing downwards (Fig. 5), but it should be in such a
position that would prevent clogging or entering of snow
and dirt, and also provide for free drain of any water that
got into it.
Installing on maritime transport, silencer must be
mounted using the bolt and a nut provided, so it would
be in fixated position.
Make longitudinal cuts (about 15mm) (see Fig. 8,
Fig. 9 Fig.11) on ends of the metal hose to ensure better
sealing when connecting the heater pipe to the pipe for
discharge of exhaust gases through the board of the vessel,
but without going beyond the pipe to be covered.
Rubber bushing (sold seperatly) must be used if
exhaust pipe goes through plastic parts, for example,
bumper of a vehicle (see Fig. 11).
The exhaust pipe needs additional insulation at every connection of
the metal hose, for example, using a heat resistant tape or sealant, to
prevent any leaks of exhaust gases at connection points.

Additional heat insulation must be installed at places where the
exhaust pipe goes through the floor or the side wall of the vehicle (Fig.
12) to avoid unnecessary fire hazard.
The end of the metal hose should not contact the rubber seal of the heater. It is advised
to install the discharge of exhaust gases in a way, that does not allow exhaust gases to flow
inside the spaces used by people, like drivers’ cabin or living quarters of maritime transport
(e.g. away from open windows, doors), to avoid the possibility of inhaling dangerous
exhaust gases.
Do not place the output opening of the exhaust pipe in front of the
incoming airflow of the moving vehicle or vessel (see Fig. 5).
3.3.1. Installing exhaust adapter on maritime transport
Exhaust gases are discharged overboard the vessel. Install the discharge of exhaust
gases in a location inaccessible to water (at least 60 cm above the waterline) and to avoid
the possibility of repeated intake of exhaust gases by the air intake pipe.
To install the exhaust pipe adapter (hull fitting), drill a hole in the hull of the vessel at
least 5 mmlarger indiameter than actual outer diameter of thehull fitting. Install the exhaust
pipe into it as per Fig.13 with the pipe looking upwards (to avoid penetration of water).
Install a rubber gasket between the flange of the exhaust pipe and the hull of the vessel to
seal the connection.
To prevent exhaust gas leaks or falling off of the
exhaust pipes, it is advised to use an exhaust cement or
different kind of sealant on every connection of the
exhaust pipe Sailboats should not install the exhaust
adapter on the side of the hull, only at the stern.

3.4 Installation of the fuel system.
Do not operate the heater using biofuel.
Use only diesel fuel standard EN590, depending on the ambient
temperature.
Act as instructed on Fig.14 and Fig.17 to install the fuel system. The fuel pump and
the fuel supply line must be protected from heating.
It is recommended to install a small inline fuel filter before the fuel pump. Make sure
that the filter is completely filled with fuel. Also make sure that you’re using fuel lines of
the same diameter as provided with the heater.
Do not take fuel from fuel filter or it’s casings, because doing so causes a
leak of fuel.
Do not take fuel from the fuel line between the fuel filter and fuel pump of
the vehicle’s engine, the return line of the engine or after the high-pressure
pump of the vehicle.
Heater is not designed to work with such high pressure.
Fuel line system should be as short as possible. Recommended maximum
length of the fuel line is 5m. Distance between fuel tank and fuel pump
should not exceed 1m and distance between fuel pump and the heater
should not exceed 4m (see Fig.14 and Fig.17)
3.4.1 Fuel suction using a fuel suction hose.
Before installing a fuel suction hose in a fuel tank of the vehicle or vessel,
make sure that the fuel level is high enough to ensure operation of the
heater, and low enough to easily remove the fuel tank, if needed.

3 –Fuel line
Fig. 14 - Example of fuel supply to the heater with fuel suction hose

17
Fuel is taken directly from the fuel tank of
the vehicle or vessel or an additional tank. Drill a
hole Ø16mm in the fuel tank to install a fuel
suction hose. When drilling the hole in the fuel
tank, follow safety precautions that should be
observed when working with a transport, which
is filled with fuel or explosive substance.
If needed, cut the immersible tube of the fuel
suction hose shorter before installation. Its
bottom end must be located about 10-15 mm
Fig. 15a –Installation of
the fuel suction hose
Fig. 15b –Installation of
the washer.
above the bottom of the tank, or at the height to provide fuel for engine in the fuel tank at
any time. The cut at the end of the fuel suction hose must be made at a 45° angle to the
axis of the tube. Remove all burrs from the cut after the work is done.
Install the fuel suction hose in the fuel tank as per Fig.15a. Install the special washer of
the fuel suction hose in the tank hole as per Fig.15b. Apply a fuel-proof sealant on the
threaded surface of the fuel suction tank to properly seal the connection between the fuel
suction hose and the fuel tank.
Never install the suction hose on the side of the fuel tank. It must be
installed on the top side of the fuel tank.
3.4.2 Fuel suction from an additional fuel tank
Consider convenience of fuelling, when installing the fuel
tank (Fig.16). Install the fuel tank in such a way that the amount
of fuel and its potential leaks from the inlet, fuel suction nozzle or
connections can be visually controlled.
When filling the fuel tank, be careful not to spill
any of the fuel on the exhaust system, wiring or
other objects, which can be damaged due to their
contact with fuel.
Fuel tank must be installed with its wide side
perpendicular to the direction of the
movement of the vehicle/vessel (see Fig. 16).

3.4.3 –Fuel suction from the fuel tank of the vehicle.
Fuel is taken from a fuel line of the vehicle using a T-piece (see Fig.17). This method
can be used if there is no pressure in the fuel line. If vehicle is equipped with a low-pressure
fuel pump in the fuel tank, then those fuel lines cannot be used, fuel suction hose must be
installed instead. Mind the installation position of the T-piece.
3.4.4 Installation of the fuel pump and the fuel supply line.
The fuel pump is connected to the heater
through its own harness and supplies fuel
depending on the required heat capacity to the
combustion chamber of the heater. The fuel
pump is operated by electrical impulses sent by
the control unit. When running, the fuel pump
makes characteristic metallic clicking noise.
It is recommended to install the fuel
pump close to the fuel tank (distance should
not exceed 1 meter (see Fig.14 and Fig.17)) and below the low level of fuel in the fuel tank,
but not lower than 70cm of the minimal fuel level (see Fig.19, point a)). But the distance
between the fuel pump and the heater cannot be greater than 1,5 meters (see Fig.19, point
b)). Fuel pump should be positioned with a slight angle pointing upwards (see Fig.18)
If for some reason sealing of the fuel pump is compromised, it is advised to install the
fuel pump lower than the heater in order to avoid leaks and overflooding the heater with
fuel due to gravity.
Remember to properly bleed the “silent” TH11 fuel pump. If it’s not
properly bled it will be as loud as standard fuel pump.
To bleed it start the heater and position the fuel pump with its outlet
upwards till there are no air bubbles in the fuel line and only then secure
fuel pump in its recommended position.

19
Attach the fuel pump to the flexible rubber clamp (supplied with the heater), which
reduces the transfer of noise to the frame of vehicle or hull of the vessel. (see Fig. 20)
Act as instructed on Fig.14 and Fig.17 to install the fuel supply lines. Use clamps to
attach fuel supply lines. Do not tighten the clamps too much trying to avoid leaks because
clamps break easily if tightened with too much force.
It is preferable to lay the fuel supply line on a straight line and with a small inclination
upwards in the direction of the heater. The fuel supply line should be fastened at equal
distances to prevent sagging, prevent effects of vibrations and avoid fractures. Do not allow
contact of the fuel pump and the fuel supply line with hot objects. Cut the fuel supply line
only using a sharp knife as per Fig.21. At the locations of cuts, there should be no narrowing
of the flow cross-section of the fuel line, dents or kinks.

3.4.5 Installation of the electrical harness of the fuel pump.
If the length of the wiring harness of the fuel pump needs to be shortened,
it is allowed to remove the unnecessary portion from the middle of the
harness. The connection point must be insulated.
Never connect the fuel pump to continuous DC power supply. It will burn
the coil of the fuel pump.
Installation of the connector of the electrical harness of the fuel pump is shown in Fig.22.
Make sure that the wiring of the fuel pump is installed in desired way before inserting
the pins of the wiring in the plastic casing.
Make sure that the pins are inserted all the way to the end and lock securely in the plastic
casing. When it’s correctly inserted, a small click can be felt. The polarity of the pins does
not matter.
3.5 Installation of wiring of the heater.
Install electric harnesses of the heater according to the diagram of electrical
connections of the heater (see Annex.4).
When installing electrical harnesses exclude the possibility of them being heated.
Install all the wire harnesses and electrical elements in dry and protected places. No
deformation or moving of wires is permissible, when the vehicle or vessel is operated.
IMPORTANT!
Fuses must be removed before installing electrical harnesses.
Battery of the vehicle or an auxiliary battery powers the heater. Control the charge of
the battery on a regular basis. It is recommended to disconnect the heater from the battery
to avoid its discharge during long dockage or storage of the vessel or vehicle. Do not
disconnect the heater from power before the purge cycle ends.
Heater must be connected touninterrupted powersupply at all times. Cutting the power
to the heater will result in loss of settings (clock, operation mode and settings).
If the heater is connected to an existing electrical installation, the wiring should be in
sufficient diameter to prevent voltage drop (main cause of error 15). It is always
recommended to connect the heater directly to the battery of the vehicle/vessel or auxiliary
battery. It is strongly recommended to use new and provided wiring for installation of the
heater.
