PURPOSE OF THE UNIT STANDARD 
Learners in the field of engineering require the skills, values and knowledge reflected in this unit standard.

The learning outcomes in this unit standard also contribute to the exit level outcomes required for the National Certificate in Mechanical Engineering Fitting (NQF level 4) and related qualifications.

Qualifying learners are able to inspect compressors, determine faults, assess requirements for repair and remove, replace and set up compressors. 

LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
This unit standard has been designed as part of a progression. It is one of a series of unit standards for machine and equipment maintenance in the engineering area.

The credits allocated to this unit standard assume that a learner has already learned to:
  • Maintain dynamic seals, bearings, pipes, drives, lubrication systems, fluid and pneumatic systems, heat exchangers and pressure vessels 
    		•

    UNIT STANDARD RANGE 
    The ranges as indicated under the specific outcomes determine the scope and level of this unit standard.

    The learner should be able to work autonomously with minimal supervision and according to worksite and manufacturer specifications and occupational safety, health and environmental legislation.

    Work is generally, but not exclusively, carried out in a team environment.
