Range Statement

This section specifies work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Bold italicised wording, if used in the performance criteria, is detailed below.

Diagnostic information must include procedures relating to:	isolating faults, including internal and external leakage dismantling, inspecting and evaluating pumping system components testing pumping system for pressure, suction and discharge.
Safety requirements must include:	work health and safety (WHS) and occupational health and safety (OHS) requirements, including procedures for: starting and operating pumping systems working with exhaust fume hazards working with 240 volt equipment.
Post-repair testing must include:	running pumping system and checking operation against manufacturer specifications, workplace procedures, and safety and environmental requirements making final adjustments and re-testing as required.
