General remarks
If the AHU is delivered in several units, they must be assembled in accordance with these instructions
and properly connected to the duct system. All protective devices must be active.
If ready-to-use AHUs (complete machines) are assembled from non-operational AHUs (partly
completed machines), the person responsible for this assembly must carry out conformity evaluation,
issue a certificate of conformity, and attach the CE marking.
Information about these instructions
These instructions will facilitate safe and efficient use of the AHU.
All persons working on the AHU must thoroughly read and understand these
instructions before starting any kind of work.
Safe working is dependent on adhering to all safety information and instructions.
Further information
The instructions describe all the available options. Whether and which options are available in the AHU
depends on the options selected and the country for which the AHU is intended. The illustrations
serve as an example and may differ.

General risk sources
General hazards
WARNING
Risk of injury due to modifications or use of incorrect spare parts
Serious injuries, death, and material damage can be caused by modifications or
installation of incorrect spare parts.
• Use original spare parts only.
• Do not make any modifications.
WARNING
Danger to life from falling!
If a grate above an air opening is overloaded downwards (>400kg), this will cause
the structure to fail. When a person steps on the grate, the structure may fail,
causing a risk to life by falling through the air opening.
• Do not exceed the maximum load (≤400kg or 2 persons).
WARNING
Danger to life from falling!
Removing the grates in the floor causes a risk to life from falling, as the opening in
the floor is exposed.
• When working on air openings with removed grates, the customer must
provide protection against falling.
• After the work, mount the grates again according to the instructions.
WARNING
Risk to life from falling objects
Risk to life from being struck by falling objects.
• Cordon off the endangered area under the opening to secure persons against
falling objects.
• After the work, mount the grates again according to the instructions.
WARNING
Danger to life from falling!
When stepping on the protection roof, there is a risk to life from falling, as the
protection roof is unsuitable for supporting loads.
• Do not enter the protection roof.

NOTE
Material damage due to localized weight
If more than one person enters the AHU at a time or localized loads are otherwise
applied, pans and floors may be deformed.
• Do not let several persons enter the AHU at the same time.
• If this becomes necessary, take suitable measures to distribute the weight
(e.g., grates, wooden boards, wood beams).

Personnel qualification
The work described in this section may only be performed if the person has the following
qualifications:
Qualified person in accordance with pressure equipment regulation
Qualified electrician
Registered gas installer
Refrigeration specialist
Crane operator
Mechanic
Forklift driver
What to do in case of danger
Fire protection
Solvent-welding agent (Rhenofol solvent-welding agent (THF) –
tetrahydrofuran) and sealing paste (Rhenofol paste)
Solvent-welding agents and sealing paste may contain toxic and environmentally
hazardous substances. Fumes can form an explosive mixture with air. Fumes are
heavier than air and spread at floor level. Ignition is possible over greater distances.
During thermal decomposition, harmful gases and fumes may be generated, and
explosive peroxides may be formed.
• Use self-contained respiratory protection.
• Wear chemical protective suit.
• Cool endangered tanks from a safe distance using water spray.
• Do not use a direct high-pressure water spray for extinguishing.
• For extinguishing, use carbon dioxide (CO2), extinguishing powder, or water
spray. Fight larger fires with water spray or alcohol-resistant foam.
• Do not allow extinguishing water contaminated with pollutants to enter
waterways or waste water system.
• Comply with the safety data sheet of the manufacturer.

What to do in case of leaks
Solvent-welding agent (Rhenofol solvent-welding agent (THF) –
tetrahydrofuran) and sealing paste (Rhenofol paste)
Personal protection
• Avoid contact with skin, eyes, and clothing.
• Ensure good air exchange in the danger zone.
• Take precautionary measures against static discharge.
• Wear personal protective equipment (tight-fitting safety glasses with lateral
guards, self-contained respiratory protection (filter type A-P2); chemical
protective gloves (suitable material: butyl rubber; thickness of the glove material:
>= 0.7 mm) and protective clothing).
• Comply with the safety data sheet of the manufacturer.
Environmental protection
• Do not allow it to enter waterways or waste water system.
• Absorb with liquid-binding material (sand, diatomaceous earth, acid binder,
universal binder).
• Disposal according to official regulations. Do not dispose of the product together
with domestic waste.
• In case of contamination of waterways, soil, or waste water system, inform
relevant authorities.
• Comply with the safety data sheet of the manufacturer.
