users of the product after installation. The document covers main rules of installation of the

product on different land vehicles and small maritime transport (e.g. yacht, boat, cutter),

function tests of the product after installation and basic maintenance procedures to ensure

reliable operation of the heater.

Please read this manual before installing and/or operating the AIR heaters. This manual

contains needful information in order to use this product correctly. Disregard of these

instructions can void the warranty of the product, lead to damage of product and/or property

and be a risk to health.

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

engine is operating and there is no battery.

•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.

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

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.
