tion) and secured against unauthorised re-operation!
Only operate the air heaters once they have been completely assembled and provided with appropriate reach-in protec-
tion.
All claims for damages or warranties become void when the installation does not comply with our stipulations or when
the fault/damage is causally related to inappropriate alterations, processing or other treatment. The user must prove that
the fault is not due to inappropriate installation.
The general maintenance instructions in the operating and installation instructions for the AL-KO air heaters must always
be adhered to.
The implementation and design of the air heater corresponds to the standards listed in the declaration of conformity and
declaration of incorporation to minimise the risk potential posed by the air heater. The potential risk can only be mini-
mised when these additional, applicable standards for the installation-ready system are adhered to by the system builder.
It must be ensured that all authorised persons have read and understood all of the operating and installation instructions
and adhere to them!
All plant, company and work instructions of the user apply in addition to these operating instructions to prevent hazards
within the company.

mate and normal atmosphere.
The air heaters may only be operated in an environmental temperature range between -20 °C and +40 °C and a humidity
range between 50% and 85% relative humidity without condensation.
Installation of the air heaters at a location more than 800 m above sea level may lead to a drop in performance and has
to be investigated on a case-by-case basis.
Different areas of application should be discussed with the manufacturing plant.
2.2 Possible inappropriate uses
AL-KO air heaters may only be operated within the range specied in the technical data provided by AL-KO. Any other or
further use that deviates from the description in Point "2.1" Appropriate use" is deemed inappropriate use. The manufac-

3. Product description
AL-KO air heaters of the COMFORT series consist of a stable, self-supporting steel sheet housing which is sendzimir-
galvanised and has additional powder coating. Individually adjustable ns are arranged on all four sides. A maintenance-
free axial fan ensures low-noise operation. The drives of the AL-KO air heaters are external rotor motors. They have a
permanently lubricated deep-groove ball bearing and the fan forms a single unit with the rotor. A heat exchanger for air
heating will be installed in the housing next to the fan. This is implemented as a nned heat exchanger (made of Cu / Al).
The air heaters can be extended with various electrical accessories.

5.2 Heat exchanger connection
Take care not to mix up the feed and reux pipe during the pipe installation.
The feed line must be connected at the bottom and the reux line at the top of the devices to ensure optimal
warm water distribution within the nned heat exchanger.
Caution!
Hold the connectors in place with a suitable tool (e.g. pipe wrench) when connecting the heat exchanger to
prevent damage.
Attach pipes and connectors to ensure free access to the heat exchangers for maintenance purposes.
When temperatures below the freezing point occur, the heat exchanger must either be emptied and blown out
with compressed air or a standard anti-freeze with corrosion protection must be lled in to prevent damage due
to frost or corrosion!
CU/AL heat exchanger:
Maximum operating pressure: 16 bar.
Maximum ow temperature: 120 °C.
Feed and reux pipes must be connected according to the professional regulations.
May only be operated with water that has no corrosive properties (e.g. no high-purity water) and that contains nei-
ther oxygen or carbon dioxide!
Valves and actuators must be professionally mounted (provided by customer).
Carefully bleed the heat exchanger.
The bleeding and draining facilities for the heat exchanger must be provided by the customer.
The complete piping must be checked for leaks!
5.3 Electrical connection
Warning!
The electrical connection may only be performed by a registered electrician and with consideration of the DIN
and VDE regulations and the directives of the local energy supply company.
The electrical connection of the AL-KO air heater must be performed according to the connection plans. Only use
the device-specic circuit diagram to connect the device.
The air heaters must be grounded.
It must be possible to switch off all poles of the supply line with a maintenance switch.
Fluctuations or deviations from the mains voltage may not exceed the tolerances specied in the technical data, as
malfunction can otherwise not be excluded.
All electrical motors of the fans have a thermal contact as standard equipment. It must be integrated into the con-
troller.
