Thank you for purchasing the MV Airo 2 Air heater.
This instrucon book describes the structures,
working principles, installaon and operaon of the
MV Airo 2. For correct use of the heater, please read
this instrucon book carefully before installaon and
use. The instrucon book should be saved in a
convenient place for reference later.
Introducon
Comply with the operaon manual for installaon
and use, to ensure prolonged and reliable operaon.
The main equipment of the MV Airo 2 air heater
(hereinaer referred to as ‘the heater’) is a small fuel
furnace controlled by a single-chip micro-processor.
Its furnace body (the heat exchanger) is located in the
hood shaped case, which serves as an independent
air passage. Cold air is drawn into the air passage by
the fan and blown out when it becomes hot.
The heat can be supplied by the heater to the driver’s
cab and passenger’s compartment independently
from the engine. The schemac diagram is shown in
Fig I.
The heater is fully automacally controlled. It
features a compact structure, easy installaon, low
running costs, easy maintenance and is safe and
reliable.

Case Assembly
Figure IV
Page 4 of 21
The heat exchanger is made of die-cast aluminium, with
radiang fins around the rear. The combuson chamber
fits inside the inner cavity of the heat exchanger. The
burner assembly and glow pin, fit into the end of the
combuson chamber. Fuel comes to the burner
assembly through the fuel pipe and is ignited by the glow
pin. The flame is passed up the combuson chamber and
returns between the inner walls of the heat exchanger
and discharged through the exhaust outlet vent to the
outside of the vehicle or boat.
The air supporng combuson of the furnace,
comes from the combuson air inlet port and
is sent down the combuson pipe by the
combuson supporng air blades of the fan
motor.

For the ease of servicing, fault finding and air flow it’s recommended that the main body is placed in an area with
easy access. Figure VI shows the minimum distances required.
Installaon of the Main Heater Body
Choose a flat installaon surface, any undulaons could cause the case to twist
and will not ensure an even mount. Make sure there are no foreign bodies
between the boom of the heater and the installaon surface itself. This will
ensure a good seal between the two. File down any drill holes to again ensure an
even mounng surface. Tighten the M6 bolts provided to a torque seng of
6Nm+1Nm.
Figure VII shows the posion of the installaon holes. If the installaon area is
less than 1.5mm thick a mounng plate will be required (Figure VIII).

Aer installaon, make sure there is no fricon
between the fan and other nearby parts to ensure
smooth operaon and make sure the heater label is
clearly visible for ease of maintenance in the future.
Avoid re-entering of the supplied hot air into the inlet
port (as shown in Figure X). If no inlet pipe is
required, make sure the grill is installed at the inlet
port instead (Figure IV no. 17).
The direcon of the heater for installaon is shown in
figure IX. Ensure you do not exceed the inclinaon
angle or normal operaon will be affected.
Make sure that the hot air outlet does not exit onto
any parts affected by heat and that it isn’t directed
toward the flow of anything that can cause a
blockage, near splashing water or near the vehicles
exhaust.

Addional Ducng (Oponal)
The combuson air inlet pipe sucks in fresh air from
outside of the vehicle and the exhaust discharges
fumes outside of the vehicle. Measures must be
taken to avoid the fumes from re-entering the
vehicle.
The pipes should exit at the boom of the vehicle,
ensuring that the openings are far enough away from
any splashing water or dirt that can clog them. Figure
XIII shows the right and wrong way to install the
pipework.

A & B – Correct C & D - Wrong
Only use the inlet pipe and exhaust provided with the
kit for installaon. The exhaust pipe is made of
corrugated stainless steel while the combuson pipe
is aluminium covered in paper and plasc. Do not
confuse the two. Use the supplied clamps to fix them
securely to the combuson air inlet and the exhaust
outlet on the heater. The protecve end cap on the
outlet of the combuson air pipe and exhaust pipe
should be kept in good condion. Do not damage or
remove them.
Both the combuson air pipe and exhaust pipe should
come downward from the heater and face opposite to
the vehicle’s direcon of travel. If the pipe cannot
avoid a curve, make sure the radius is no smaller than
50mm and the sum of all curves does not exceed
270˚. Figure XIII shows the right and wrong way to
install the combuson air intake. Note that it is the
same for the exhaust too.

When the heater is operang, the exhaust will get
hot, so make sure it is installed away from any parts
that could get damaged by high temperatures. The
exhaust vent should also point downward to the road
surface with an angle of 90˚±10˚ This is best achieved
by fixing a clamp 150mm from the pipe end.
Any exposed exhaust should be covered with a heat
shield to prevent scalding.

Where possible the fuel line is ideally placed uphill to
the fuel pump to ensure ideal bleeding of the fuel
line.
Always fit the fuel pump on the an-vibraon mount
securely onto the vehicle. Ensure the outlet of the
fuel pump lts upward. The correct angle is shown in
Figure XVII.

Figure XVIII shows the correct way to connect fuel
lines to prevent the build-up of air bubbles. Ensuring
they are flush and minimising bends.
When the fuel is being sucked from the vehicle tank,
or an independent tank, a sucon pipe is required.
Make sure all the openings are appropriate for the
installaon and a ght seal is maintained for the base
of the sucon pipe.
The boom of the sucon pipe should be about
30-40mm from the boom of the fuel tank so as to
avoid sucking impuries or sediment from the
boom of the fuel tank.

Figure XVII shows the ideal way to mount the fuel
pump
The fuel pump’s outlet should lt upward at an angle
between 15˚-35˚(as shown above).
Only use the fuel line provided, ensure the pipe is
placed away from any possible debris and avoid any
sagging in the line. Make sure the fuel line does not
flow downward toward the fuel pump. This will
prevent correct fuel flow and produce air bubbles in
the line.

Fuel Standpipe
A fuel standpipe (or sucon pipe) will need to be
installed in the vehicle’s fuel tank or an
independent fuel tank depending on what the
installaon calls for. Sealant is not required to fit
the standpipes.
The boom of the fuel standpipe should be
30-40mm from the boom of the fuel tank to allow
enough sucon of fuel and at the same me not
allow impuries and sediment to be drawn up the
standpipe.
Depending on the standpipe provide in the kit you
will need to install the standpipe in one of two
ways.
Figure XIX
Standpipe 1: (Part No: AHZ-034)
Usually supplied in Marine kits and
supplied bent, this standpipe is
installed like so:
Drill a hole in the top of the
vehicle’s fuel tank Φ22 ± 0.2mm in
size. Ensure it is smooth and clean
of burrs

Fit the standpipe by lng it into
posion into the newly drilled hole

Place the rubber and metal
washers back on top followed by
the nut and ghten it securely on
top

Cut the standpipe down to size if
necessary

Remove the top nut and washers
and bend the standpipe straight

Stand pipe 2: (Part No: AHZ-035)
Figure XV
Supplied mainly in vehicle kits, this
standpipe is installed like so:
If possible; remove the sender unit
from the vehicle’s fuel tank, this
will make it easier to aach the nut
securely back onto the standpipe

Replace the nut on the standpipe
to secure it safely to the sender

Replace the sender unit into the
fuel tank.

Remove the nut from the
standpipe and feed it through the
hole ensuring the rubber ‘o’ ring
remains on the standpipe ‘head’
side

Drill a Φ
± 0.2mm hole into the
sender unit

NOTE
Any exposed wire outside the vehicle should be
protected so as not to be ripped by any road
debris or similar.
The previous page shows the wiring diagram for the
heater. The wires of the main heater have been
made into bundles. They can be laid according to
the posions of various components and should be
fixed to the proper locaons. The distance between
two fixing points should not exceed 300mm.
Connect the main wiring harness to the heater by
gently removing the juncon box cover. Connect
the 12-wire connector of the main wiring harness
to the controller socket (X7). The main harness can
exit the heater to the le or to the right. Then
replace the cover ensuring a good seal is kept all
the way round. A fuse will already be inserted into
the fuse holder (20A for 12V heaters and 15A for
24V versions).
Connect the 2.5mm²red wire and the
2.5mm²brown wire in the wire harness to the
spring terminals and then to the posive and
negave of the vehicles baery.
Straighten the fuel pump leads (two 0.6mm²black
wires) and put them through the opening on the
wall of the air inlet pipe. They can then be
connected via the spring plug straight to the fuel
pump or using the fuel pump extension loom if
more length is required.
Use a single screw to fix the mer control or
rheostat control in place. They are best installed so
that they can be seen and operated easily to
idenfy working condions and for easy access. The
black and clear plugs connect to the corresponding
plugs on the loom (below). The remaining three-pin
socket on the mer or rheostat control plugs into
the remote-control receiver if one is installed. An
adaptor cable may be necessary.

the lines and that all electric terminals fit securely
together.
To ensure a long life of the heater it is advised that
you run it for at least 10 minutes every month, to
prevent malfuncon of mechanical parts.
Aer 10 years the heat exchanger, overheat sensor
and exhaust should be replaced by a professional.
If any welding is being aempted on the vehicle,
please remove the posive power supply wire and
earth it to protect the controller from any damage.
Check the air inlet and outlet for any
polluon or foreign maers
Clean the externals of the heater
Check for corrosion or loose connecons of
the circuits
Check the combuson air inlet and exhaust
pipe for damage and clogs
Check the fuel line for leaks
