Mounting styles and hole cut-outs for type LM

The fan sleeves for type LM can be fixed in 4 different ways, depending on the hole cut-outs and space circumstances. It has to be used just one hole cut-out possibility to mount the sleeve on a mounting plate or housing wall.

Plug-in mounting style/ hole cut-out no.1

First of all pull the sleeve over the flange of the fan. Then plug-in the four pegs through the drilled holes B of the mounting panel and pull them out on the backside. Therefore the drilled
holes need to be chamfered slightly from the installation-side.

This hole cut-out is preferred, if space circumstances are very tight. The backside however needs to be accessible for being able to pull out the pegs.

Steckmontage

Plug-and-pull mounting style/ hole cut-out no.2

First of all plug in the four pegs through the 45° outbreaks in the mounting panel and then pull them lateral into the holes C2. Now put the fan into the sleeve and pull the corners over
the flange of the fan.

This hole cut-out is preferred, if there is enough space arround the fan for being able to pull the sleeve over the flange. The backside needs not to be accessible.

Steck-Ziehmontage

Plug-and-turn mounting style/ hole cut-out no.3

First of all pull the sleeve over the flange of the fan. Then plug in the four pegs into the larger holes C1 of the mounting panel and turn them into the smaller holes C2.

This hole cut-out is the most popular one. However there must be enough space for installation for being able to turn the fan including the fan sleeve. The backside needs not to be
accessible.

Steck-Drehmontage

Plug-and-push/ pull mounting style/ hole cut-out no.4

First of all pull the sleeve over the flange of the fan. Then plug in the four pegs into the larger holes C1 of the mounting panel and push or pull them into the smaller holes C2.

This hole cut-out is also a very popular one. However there must be enough space for installation for being able to push/ pull the fan including the fan sleeve in one direction. The
backside needs not to be accessible.
