Where vendors provide recommendations for site storage and protection these are to be followed and take precedence over the following recommendations.
Where prolonged site storage is involved, which is not under the control of vendors, equipment guarantees are invalidated. However most vendors offer a re-furbishing service after which equipment guarantees are re-instated. Such a service is outside normal Company contracts but clients are recommended to take up this option where applicable at their own expense.
A warm, clean, dry and vibration free environment in a secure under cover storage area is required. Recommended environment conditions are temperature range of 15°C to 30°C and a humidity of between 30 to 40%.
Instruments can be stored in the above environment for up to 4 months in their shipment cases. However, where cases/packing have been opened the plastic coverings are to be retained and resealed in the manner they were shipped.
Where moisture absorbents are included they are to be replace with the new charge on receipt on site and further replaced at regular intervals thereafter.
Adjacent 220 and 110 volt supply made available for energizing equipment as necessary.
Panels to be stored up-right and level, any temporary transportation/strengthening supports to be reinstated and maintained.
