Assembly instructions 8-2
8.1. Installation of the exhaust fan for regeneration of exhaust
air
When plastics are being dried that release harmful gases during the drying process, care must be
taken that the regeneration exhaust air is disposed of in an environmentally sound way. At the
same time the throughput of the regeneration blower must not be altered. It should be noted
when assembling a disposal system (e.g. an exhaust system) that the regeneration exhaust air is
very humid. Thus condensation may form, which must not under any circumstances return to the
dryer.
8.2. Grounding the equipment against electrostatic charging
Considerable electrostatic charging may occur in the equipment during processing of the various
materials. For this reason, all components must be sufficiently grounded, see grounding bolt dryer
(A) and drying hopper (B).
Ensure that all state and local electrical regulations are observed.
