8.0 TRANSPORT / STORAGE

Severe shock and vibration should be avoided during transport. Store it in a clean and dry environment.
Regulator is ready for operation upon delivery. The protective port plugs should not be removed until
immediately before connecting plumbing the regulator. To avoid damaging regulator or/and pilot motor, do
not lift or carry by the handle.

It is recommended to transport it with the lifting equipment suitable for the weight to be moved. Do not hook-up
lifting equipment to accessory such as handle, or pressure bores. When using a suspension belt it must be
placed around the regulator body, providing edge protection and ensuring weight distribution.

existing sealing surface on the connections from damage. Do not damage the corrosion protective layer.
