Delhi Industries BI Series Operation Instructions And Parts Manual

MODELS: BI-10 THROUGH BI-36, BI-10RM THROUGH BI-36RM
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 BI/BI-RM
Series Blowers. Failure to comply with instructions could result in personal injury and/or property damage. Retain
instructions for future reference.
DELHI BI series blowers are specifically designed as a quiet and efficient blower. The BI series incorporates a
backwardly inclined (BI) blade configuration to generate air moving performance. The BI series are single inlet blowers,
which have a standard CCW rotation and bottom horizontal discharge. The discharge direction may be easily altered to
any one of eight positions without removal of the wheel venturi or housing.
Complete access for motor and drive installations and servicing may be completed by partial removal of the drive
compartment cover assembly. Pre-lubricated ball bearings, motor adjustment hardware and a dynamically balanced
wheel are standard equipment. Operating temperature range is –65 to 220 deg. F.
