Installation instructions

Do not commission a damaged blower. Repair work may only be undertaken by trained specialists.
Route the duct/ventilation duct to the installation site. If there is an existing duct system, cut the duct at the installation site.
Ensure that the power cable is permanently routed to the installation site.
Mount the blower 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.
To avoid sound bridges to the building structure, observe the distances to other façade components. If necessary, use isolating elements.
If there is a free inlet, fit a suitable protective grille (e.g. SGAI, SGAI ES, SGEI, SGEI ES) to the inlet and outlet of the centrifugal blower. Use the existing drilling positions on the housing for fastening. Mounting material is to be provided by the customer.

The impeller is balanced in accordance with ISO 14694 and ISO 1940-1. The vibration level of blowers 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 category and prescribed limit values).

Before installation, check the application category of the blowers 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).
Install a function monitor with alarm function to warn persons in case of malfunctions/unit failure and to avoid damage to property.
