(max. 2.5 Nm). When doing so, hold the rotor in
place by the outer edge using your hand. Finally,
check the mechanical freewheeling of the rotor by
rotating it by hand.
The rotor is equipped with rare earth mag-
nets.Duetothestrongmagneticfields,chipsand
particles may adhere to the inside of the rotor.
Chips and magnetic particles can be collected
from the rotor disc with a commercially available
holding magnet. Clean the rotor disc to remove
any adhering particles and chips before reassem-
bling the rotor.
Sealing air supply
A sealing air supply is required to fulfill the
Rotoclear seal guarantee and is provided as stan-
dard for the adhesive and screw-mounting meth-
ods.
Under moderate conditions the unit can also be
operated without a sealing air supply (e.g. if retro-
fittedorconverted).
Installation with sealing air (Rotoclear
seal guarantee)
The sealing air is fed into the system through the
sealing air line (Fig. 8-G) via the plug-in connec-
tion (Fig. 8-H) on the electric-pneumatic adapter
and supplied to the unit through the protective
hose. The sealing air prevents the ingress of cool-
ing lubricants, oils or other liquid media. Sealing air
must always be connected to maintain the Roto-
clear seal guarantee. The air pressure must be
individuallyadjustedduetothedifferentpossible
sizes of supply lines.
For safe operation of the unit, a back pres-
sure of 2-5 mbar (200-500 Pa) is required at the
connectionbox.

It is also important to ensure that the gap is not
worn (e.g. by dirt). As a result, the specified seal-
ingairrequirementmaynolongerbesufficientfor
an absolutely tight device. Worn parts must be
replaced immediately to ensure proper function-
ing.
