GENERAL SAFETY
Rotating parts, (pulleys, shafts and belts) on fans should not be exposed. Where these components are not protected by ductwork, cabinets
or covers, appropriate guards should be employed to restrict exposure to rotating parts. Access doors should not be opened with the fan
operating to avoid foreign objects being drawn into the system. On initial start-up, a careful inspection should be carried out to ensure no
foreign material is present which could become airborne in the system.
Read installation and operation instructions carefully before attempting to install, operate or service Canarm/Delhi 300 Series. Failure to
comply with instructions could result in personal injury and/or property damage. Retain instructions for future reference.
