Fan unit ELS EC..
The ELS EC fan is a device with protection class II without a protective conductor.
If a residual current circuit breaker is used, there is no restriction on type selection from the perspective of the ELS EC fan.
The selection depends on other operating equipment with a protective conductor, which are provided for in the same
installation.
6.1

Installation of fan unit

Remove the delivery unit from the packaging directly before installation to prevent any possible damage and conta-
mination during shipping and on the construction site. If the flush/surface mounted casing is distorted or dented by
improper installation or should the fan unit fall to the ground or be damaged in another way, installation must be avoided
since faultless functionality is no longer guaranteed. The installation and commissioning of the fan unit must only take
place after the completion of all other trade work and after the final cleaning to prevent damage and contamination of
the fan unit.
