+ Controls and guide tubes: Compatible with standard (660 type) remote controls and source guide tubes.

+ Inspection requirements: Daily pre-operational inspection for obvious damage to the system.

+ Maintenance requirements: Most national regulations require inspection and maintenance of the system at quarterly intervals. The complete annual servicing ensures the integrity of the system

Shorter frequencies of inspection and maintenance are required when the system is operated under severe operating environments. In some cases, the system should be serviced immediately after certain jobs in severe environmental working conditions.

+ Operating temperature range: -40⁰ to 300⁰F (-40⁰C to 149⁰C).
