General Information

Shipping & Storage

Each VAV order ships with service literature. When unpacking, make sure that the literature is not

lost or discarded with the packing material. Visually inspect the individual components for obvious

defects or damage. All components are thoroughly inspected before leaving the factory. Any

claims for damage incurred during shipment must be filed with the carrier.

If any component of the VAV system and/or field installed accessories must be stored for a period

of time prior to installation, they must be protected from the elements. The storage location

temperature should be between -40° to 150°F (-40° to 65.6°C) and the relative humidity should be

10% to 90%, non-condensing. The warranty will not cover damage to the VAV or controls due to

negligence during storage. A controlled indoor environment must be used for storage.
