General Information
Shipping & Storage
Each VAV product and its service literature are shipped in the same package. 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.
When any component of the VAV system and/or field installed accessories must be stored for a
period of time prior to being installed, 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 system or
controls due to negligence during storage. A controlled indoor environment must be used for
storage.
