Elements and Performance Criteria

1. Ensure sprinkler irrigation system is prepared for operation
   • Staff are trained in carrying out pre-start checks and routine servicing
   • The irrigation controller is programmed and/or adjusted to meet the required schedule
   • Procedures are established for adjusting valves and checking filters and emitters
2. Develop and implement start-up and shutdown procedures for a sprinkler irrigation system
   • Start-up procedures for a sprinkler irrigation system are developed according to system specifications and technical manuals
   • Shut down sequence and isolation procedures are developed according to system specifications and technical manuals
   • Safety/security lock off devices and signage is installed according to enterprise policy and procedures
3. Carry out trouble shooting for faults and blockages
   • Access to faulty components and blockages is arranged
   • Faulty components are removed from the system, according to system specifications and technical manuals, and repaired or disposed of in an environmentally responsible way
   • Replaceable components are selected from manufacturer catalogues and procured using enterprise procedures
   • Replacement components are installed to meet system specifications according to technical manuals
4. Measure performance of a sprinkler irrigation system

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package
Overview of assessment
Critical aspects for assessment and evidence required to demonstrate competency in this Unit	The evidence required to demonstrate competency in this Unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following develop procedures for system operation troubleshoot faults and blockages measure performance of the system benchmark energy and water efficiency of the system
Context of and specific resources for assessment	Competency requires the application of work practices under work conditions Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances

Range Statement

The range statement relates to the Unit of Competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Sprinkler irrigation systems may include:

sprinkler irrigation systems describe systems that use spray or rotor type sprinklers to distribute irrigation water at higher volume including pop-up sprinklers, fixed, and movable sprinklers (e.g. K Line and Ezy Shift).
