If several trailers will be proved, the prover piping should be assembled and cooled within 15 minutes. If this
cannot be done, the piping will need to be blown dry using nitrogen. DO NOT USE SHOP AIR.

WARNING: Condensation will quickly form inside piping left unattended. This will cause ice to form on the
turbine bearings, preventing rotation and rendering the prover inoperable.

When all proving has been completed, CLEAN and DRY prover system. Place all components including
temperature probe and all cables in proper case for storage.
