N Instructions to enable adjustment and maintenance safely
N.1 Protective measures and additional protective measures
Adjustment and maintenance must be done by skilled technicians.
The units are provided with guards to avoid unintended hazards and injury because of rotating parts in the unit. The potential sources of
harm are the fans with fast rotating impellers. Hazards from the impellers are obvious during operation, but when power is cut-off, the
impellers are still potential hazards due to after-run for at least 120 seconds.
The fan guard’s are the inspection doors and the doors are provided with locks.
Other motor-driven parts are dampers with damper motors and rotary heat exchangers. Keep hands away from places with risk of injury.
