2.4.4 E
XHAUST SYSTEM
One exhaust gauge of 165 mm (6.5”) is provided. This should be connected with the customer’s
exhaust system (not supplied by Vitronics Soltec).
• Inflammable and/or explosive gas might develop in the machine because of the evaporation of
the solvent in the flux.
• An exhaust system that functions well, will bring the gases below the explosion concentra-
tions.
• It is therefore necessary to have a sufficient exhaust in the machine.
• The exhaust system also has to be checked continuously on its well functioning.
• The machine is prepared to interfere in the E-stop circuit of the machine with a potential free
contact of the exhaust system. This contact has to be normally open, and therefore closed
when the exhaust functions well (fail safe).
NEVER USE THE MACHINE WITHOUT THE EXHAUST SYSTEM .
