External Piping to the Drive

External Piping Cleaning

Rockwell Automation liquid-cooled drive piping and heat exchangers are flushed
and cleaned at the factory and piping is capped to prevent contamination. Leave
the drive pipe caps installed until final assembly.

Use stainless steel capped piping and valves to maintain cleanliness before
welding or assembly. Parts must be stored in a clean, dry area.

All external piping must be cleaned and flushed before installation to ensure
proper coolant system and drive pump operation.
