ESI - Efficient Silent Inline Fan

Description
PennBarry fans consist of a fan housing, impeller, shaft, bearings and motor mounting plate (where required). All impellers are
statically and dynamically balanced. Fans suitable for restaurant exhaust appliances (YZHW) are accordingly labeled. These units
require installation according to NFPA -96 standards, local codes and general practices.
Receiving and Inspection
PennBarry fans are carefully inspected before leaving the factory. When the unit is received, inspect the packaging for any signs of
tampering. Inspect the unit for any damage that may have occurred during transit and check for loose, missing or damaged parts.
Mishandled units can void the warranty provisions. If units are damaged in transit, it is the responsibility of the receiver to make all
claims against the carrier. PennBarry is not responsible for damages incurred during shipment.
Avoid severe jarring and/or dropping. Handle units with care to prevent damage to components or finishes. If the unit is scratched due
to mishandling, the protective coating may be damaged. Incorrect lifting may damage the fan and void the warranty.
