Installation instructions

• Do not commission a damaged fan. Repair work may only be undertaken by trained specialists.
• Note the air flow and rotational direction according to the arrows on the sticker → Unit overview.
• For the connection to the duct, use a flexible coupling that matches the nominal fan size.
• Mount the fan securely. Use screws of a suitable diameter at all intended fixing points and tighten to the correct torque. Mounting material that is sufficiently dimensioned and suitable for the surface is to be provided by the customer.
• Use sufficiently dimensioned vibration dampers. More information is available on request.

The impeller is balanced in accordance with ISO 14694 and ISO 1940-1. The vibration level of fans is checked ex factory in accordance with ISO 14694. The vibration level must be checked again at the installation site in accordance with ISO 14694 (vibration values according to fan category and prescribed limit values).

• Before installation, check the application category of the fans and the vibration limits for on-site tests, in particular for the start-up, alarm and stop operating statuses. Run a vibration check and check the vibration values after commissioning (ISO 14694, BV-3, Veff. max. 4.5 mm/sec.). If required, install components for avoiding vibration.
• Install the command equipment needed for starting, stopping, emergency stops or resetting after an emergency stop. Undertake installations in accordance with the planning documents and relevant regulations (EN 60204-1, EN 14118, EN 14119, EN 14120).
• An earth connection is mandatory for DAR fans used in outdoor areas. Route an earth conductor to the installation site for the earth connection (IEC 60364-5-54).
• Install a function monitor with alarm function to warn persons in case of malfunctions/unit failure and to avoid damage to property.
