Storage procedure
Upon receipt, check both the high pressure Strainer and the packing case for any transit damage.
Any damage to the strainer should be reported immediately to Narvik-Yarway or their local agent.
Any damage to the packing container should be rectified to prevent the ingress of dust or water,
prior to placing the strainer into storage.
Check the information contained on the identification plate/tagplate and documentation and return
the strainer to its packing with protective covers in place.
For short term storage, up to 6 months duration, no additional preservation measures are
necessary.
Retain the strainer in its original packing in a clean, dry indoor location. If outdoor storage is
unavoidable, then the packing case should be enclosed in a waterproof cover.
For long term storage use only a dry indoor location. Apply a cosmoline type grease to machined
faces.
Retain the strainer in its original packing and inspect at 3 monthly intervals to ensure that no
deterioration has occurred.
Before placing the strainer into service, inspect all components, seals etc., to ensure correct
functioning. Follow the procedure for installation as described before.
