Purpose and Rationale of the Qualification
Purpose:
This qualification enables a competent learner at NQF Level 2, under supervision, to demonstrate a basic ability to install, service, repair and operate mechanical equipment that is used in the air conditioning, refrigeration and ventilation industry.
The technical skills required for this purpose are scarce and there is a growing demand for technicians skilled in the mechanical, electrical and thermal sciences. These qualifications are ideally suited to school- leavers (male and female) who have an interest in the engineering sciences and have practical skills. This series of qualifications also equips the learner with entrepreneurial skills which would lead to self employment in the SMME field (Most businesses in the field of air conditioning, refrigeration, and ventilation are in fact SMME`s).
This qualification specifically suits learners who have an interest in science and mathematics as well as manual dexterity (ability to use tools) and a consciousness of personal and environmental safety.
Learners credited with this Qualification will be able to:
- Identify and handle refrigerants.
- Identify and use basic tools.
- Identify and work with component parts for air-conditioning, refrigeration and ventilation equipment.
- Understandthebasicoperationofair-conditioning,refrigerationandventilationsystems.
- Work safely and responsibly in the plant environment.
This is the first qualification in a series of qualifications which will lead to a learner acquiring all the skills required to work in the industry in the repair, maintenance, installation, manufacture and ultimately design of the mechanical/electrical systems which provide temperature control for environmental or process needs. By qualifying at this level, a learner will achieve the status of an Assistant Mechanic. The broader framework of qualifications (2008) is demonstrated by the following hierarchy of qualifications:
- Assistant Mechanic-Level 2 (Technical competence – Has a basic understanding of equipment and is able to carry out technical work under supervision).
- Mechanic – Level3,- (Technical competence-Has a knowledge of equipment and systems and is able to carry out technical work without supervision).
- Artisan-Level 4, – (Technical competence – Has an advanced knowledge of systems and equipment and is able to work without supervision and to supervise a team).
Learning Assumed to be in Place and Recognition of Prior Learning
This qualification assumes that the candidate has already achieved a General Education and Training Certificate at NQF Level 1 or ABET Level 4 or Grade 9 school level.
