2.2 Additional Safety Regulations for the Use of the Air-to-Air Heat Exchanger
• Do not reach into the running air-to-air heat exchanger.
• Do not open cover before unit is powered-off.
• Please consider that the fan is running on after the heat exchanger is powered-off.
• Do not open the cover when device is running.
• Safety mechanisms must not be removed or deactivated
For damages caused by improper installation or non-observance of the safety regulations, häwa cannot be made liable.

3. Features

The air-to-air heat exchanger is state-of-the-art technology and complies with the context of its intended use and coherent safety requirements, at the time
when the product is launched on the market. The air-to- air heat exchanger is supplied with an EC Declaration of Conformity (see attachment) and
corresponds to the Machinery Directive 2006 / 42 / EG.

3.1 Intended Use

This air-to-air heat exchanger is designed for heat dissipation from control cabinets to protect temperature-sensitive components. The device must be
operated in accordance with the specifications and notes of this operation manual and the related technical data sheet.
Any improper use or handling may result in damages to the unit, material assets, the environment and even cause personnel injuries.
The cabinet to be cooled must correspond to protection class IP54 or even higher to avoid excessive condensation. If the ambient temperature is lower than
the temperature inside the cabinet, we recommend to install an air-to-air heat exchanger.

3.2 Predictable Misuse or Improper Handling

Any modification of the device and any predictable misuse or improper handling will invalidate the manufacturer's EC Declaration of Conformity and the
Incorporation Regulations Certification awarded to häwa GmbH.
Predictable misuse or improper handling:
• Use in case of non-eliminated error messages / failures
• Use with open cabinet door
• Outdoor use (option: outdoor use is possible for modified versions upon request)
• Use with removed or deactivated safety mechanism
• Use in non-fixed condition
• Improper use of the device

3.3 Residual Risks

Constructively, not all hazards, without limiting the intended functionality of the air-to-air heat exchanger, can be avoided.
The residual risks of the device have been analyzed and assessed by means of a risk assessment.
Possible unavoidable construction risks:
• Injury caused by falling of the air-to-air heat exchanger during unpacking or assembly.
• Scrapes or crushed limbs caused by non-observance of the operating instructions.
Existing residual risks can be avoided by doing the following:
• Careful working
• Observe all notes on the device
• Observe all notes on the packaging
• Observe all notes in this manual
• Follow the general safety regulations and rules

4. Handling and Storage

The devices can be transported and stored in any position. Damages must be reported immediately to the freight forwarder. Non-observance of the
transport and mounting instructions will void any warranty. Air-to-air heat exchangers can be operated in any position.
Please provide the following environmental conditions during transport, storage and operation:
• Dry
• Frost-free
• Dust-protected
• Corrosion-protected
