10) This relates to the competency standard unit as a whole providing the range of contexts and conditions to which the Performance Criteria apply. It allows for different work environments and situations that will affect performance. Inspection should be planned with the appropriate parties to determine access, conditions and work requirements. Equipment may include air conditioning (refrigerated and evaporative), water coolers, packaged air conditioners, refrigerators, split system air conditioners, cool rooms, constant temperature baths, refrigerant air driers, central air conditioning cooling systems and industrial process freezers. Materials may include solvents, insulation tape, contact cleaners, heat shrink, vacuum pumps, gas recovery units and gas bottles. Components may include fuses/circuit breakers, overloads, indicator lamps, plugs, residual current devices, earth leakage circuit breakers, light emitting/power diodes, ultra-sonic level/proximity flow rate sensors, magnetic level switches and plate heater exchange/liquid receiver/liquid injection/TX valve controllers and uninterrupted power supplies. Test and measurement instruments may include manifold gauges, thermometers, insulation testers, voltmeters, ammeters and refrigerant detectors. Fault finding and diagnostic techniques may include linear approach, half split rule, sensory detection and insulation/continuity tests. Tests and operational checks may include correct air circulation, drainage, vibration, correct temperature, noise, pressure checks and leak detection. Work may be performed with equipment on line. Work completion details may include plant and maintenance records, job cards, check sheets and on device labelling updates. Work site environment may be affected by nearby plant or processes, e.g. heat, noise, dust, oil, water and chemical. Isolations can refer to electrical/mechanical or other associated processes. Generic terms are used throughout this Training Package for vocational standard shall be regarded as part of the Range Statement in which competency is demonstrated. The definition of these and other terms are given in Section 2.1 Preliminary Information and Glossaries. |
