WARNING
Risk of fatal injury due to electric shock caused by water damage
The device meets protection degree IP 20 according to EN 60529: 2014 and is not protected against
water ingress. Vacuum pumps operated on the floor lead to leakage current in penetrating and sur-
rounding water. There is a danger to life from electric shock when making contact with live water.
► In case of water damage, disconnect the complete power supply from the area affected.
► Provide an on-site electrical fuse protection (e.g. RCD) in hazardous areas.
► When selecting the installation location, observe potential damage from water.

Procedure
► Place the vacuum pump on a flat, horizontal surface.
► Always keep the connections and manual control elements freely accessible.
► Keep the specifications on the motor rating plate visible and freely accessible.
► With stationary installation, if necessary, secure the vacuum pump on the standing area with all 4
fixing holes (M8).
► When installing the pump in a closed housing, ensure adequate air circulation.
5.2 Connecting vacuum side
WARNING
Explosion hazard if particles enter the vacuum connection
During commissioning, there is a risk of foreign particles entering the vacuum chamber, forming a
source of ignition, and potentially resulting in an explosion in combination with explosive gases.
► Use a suitable protective strainer at the vacuum connection.
► Do not remove the strainer until you are sure that no solid particles can enter the vacuum pump.
Preventing throttling losses
Using short vacuum lines with a large nominal diameter prevents throttling losses.
Condensate separator
Pfeiffer Vacuum recommends the installation of a condensate separator in case vapors are
formed from moisture during evacuation.
