1 Safety advises
Please consider the following advice for your own safety.
•Please have maintenance work and repairs exclusively carried out by authorised
personnel.
•Do not grip into the unit and do not put objects inside.
•Maintenance work is to be carried out only when the blower-motor is not running. In
order to avoid injuries, the blower is to be separated from the current circuit.
•Attention! Danger of burning! Please do not get into contact with the heat
exchanger and its connections. Cooling tubes and cooling hoses can be hot and
stand under pressure. Be careful by touching them. This also applies to the
resistance on the blower when working at the opened unit and the construction part
has not completely cooled down.

The heater versions differences are the nominal voltage, the sockets quantity
and diameter and the air outlets.
The version 151-701-0017 can be delivered without heat exchanger as an
ventilation unit with part no. 136-701-0017.
The version 151-701-0023 has an air suction case.
All versions have a housing made of steel sheet.
The heater is delivered by AURORA completely pre-mounted, the installation
into the vehicle is carried out by the customer.
The flat tube heat exchanger with connection diameter 15 mm and the twin
radial blower DRG 370 are integrated into the heater.
The different blower speeds are achieved using a dropping resistor.
The blower is protected against overload by a micro-temperature-fuse MTS
connected to the resistor.
3 Function description
The blower sucks in the air via the opening. The air goes the heat exchanger,
heat up and will be lead into the interior.
You can choose between 1-,2-,and 3-speed level blower versions. The blower
will be operated with a switch, e.g. the AURORA Control-Panel, deliverable as
an option.
Example for a version with three speed level:
switch position 0 blower is out
switch position 1 slowest air outflow (slow speed level))
switch position 2 medium air outflow (middle speed level)
switch position 3 maximum air outflow (highest speed level)
The heat exchanger brought forward the heat to the air that flow through.
The heating power can be operated by opening or closing the water valve with
a control panel (accessoir)
4 Mounting informations
•Serving work may only be carried out by trained and authorised personnel.
The units should be handled and assembled expertly according to the
installation instructions.
•Modifications must be approved and released by AURORA. Otherwise the
guarantee will automatically become invalid.
•You should similarly agree the purpose of the application of the heating unit
with AUROA. This is particularly true where extreme environmental conditions
can arise at the installation location such as e.g. unusual temperatures,
vibrations etc.

Technical Information
no.

status: 14.07.05
•Take note of the installation location in the cab. Install the unit according to
the space available at the most appropriate spot on the mounting points
provided.
•The fixing points must be level to avoid strains in the unit housing.
Consequences
The function of the unit can be impaired if you don’t follow this advice. The unit
housing may even become damaged.
If water gets into the unit its function can also be impaired under certain
circumstances. You should therefore fit the unit at a location which is protected
from water.
Please pay attention to the actual technical supplement to the general terms of
sale and the safety instructions in contact & Info of www.aurora-eos.com.
Take care of the mounting position of the Trolly. The axis of the blower motor
must be in a horizontal position.
Before installation of the device the electrical connection and the water
connection are to be set up.
The warm air hoses are pushed over the heaters sockets. According to the
installation situation it may be necessary to provide additional means of fixing
the warm air hoses using a worm drive hose clip over the sockets.
It is essential to use appropriate worm drive hose clips for connecting the warm
water hoses to the heat exchanger.
The fixing of the heater is made with screws to the mounting links slotted holes
7x10 mm of the housing sheet.
5 Operation
The operation is made with vehicle side operation elements.
AURORA can deliver a Control Panel (accessories) for the operation.

8 Maintenance
The heater is maintenance-free. To assure an optimal function for a long period
we recommend a regularly check of:
- hoses for chaffing and kinks, damage and porosity
- the fixing, leak control and laying of the hoses and fittings.
The hose fixings are to be tightened if necessary.
- the electrical connections on the correct state and firm position
Cooling water circuit:
When refilling the cooling water quality has to be considered. When using
AURORA water valves the warranty expires when defects occur due to
contamination in the water circuit. (see TI 971-190-0003 anticorrosion/antifreeze
solution. Please order in the case of need)

Fault Cause Remedy
Blowers will not work Fuse defective or
loose Is the fuse correctly seated? If
necessary insert correctly. Renew
defective fuses. If a new defect occurs
within a short time this indicates a
possible short-circuit.
Examine blowers for a blockage or
another type of defect and rectify the
cause.
No vehicle power Switch on ignition and/or main battery
switch.
Check battery charge level.
Check battery connections.
Check vehicle operating instructions for
possible advice.
Connecting plug has
become loose
Is the plug connection seated properly
at the rear of the unit? If not assemble it
correctly.
Check connection on blower switch.
Open up the unit and check the
internal electrical connections.
Connecting cable
damaged or torn out
Replace cable. Check for correct
cable routing and connections
according to the drawing.
Electrical connections
reversed
Check connecting wires according to
the drawing and if necessary assemble
correctly.
Blower switch
defective
test switch or change it if necessary
Blockage in fan unit Rectify the cause of the blockage, e.g.
object in impeller. If necessary install
new fan unit. WARNING! Observe safety
instructions.
