GENERAL SAFETY
Rotating parts 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 Delhi DPL/DPL-AF
Series Blowers. Failure to comply with instructions could result in personal injury and/or property damage. Retain
instructions for future reference.
