Wiring diagram
• The device must be connected by a qualified expert in accordance with the connection diagram.
• The mains connection must have a sufficient wire cross-section.
• It must be ensured that the connection lines do not come into contact with the heating element tube and are
not exposed to the hot air jet.
S1:
A suitable device for full disconnection from the mains with a
contact distance of 3 mm
must be provided
in the mains connection.

Attention: Always operate device with air supply !
• In order to protect the device and heating element, the specified minimum air volume must never be fallen
below and the maximum temperature (hottest point measured 3 mm before the
heating element tube (6)
)
must never be exceeded. If the minimum air volume is fallen below, the heat output must be interrupted im-
mediately.
• Observe direction of air flow.
• Do not exceed the specified maximum inlet air temperature !
• Leister blowers must be used as an air supply (observe direction of rotation and compression preheating).
• Use a Leister stainless steel filter on the blower air intake if the air contains dust. In the case of critical dusts (e.g.
electrically conductive, damp or metal dusts), special filters must be used to avoid short-circuits in the device.
