UEERA0081 Select refrigerant piping, accessories and associated controls

Modification History

Release 1. This is the first release of this unit of competency in the UEE Electrotechnology Training Package.

Application

This unit involves the skills and knowledge required to select refrigerant piping, accessories and associated controls. It includes selecting refrigerant piping, accessories and controls for refrigeration and air conditioning installation to comply with regulations, industry standards and specifications. It also includes developing refrigerant pipe work arrangements; selecting pipe work and fittings, refrigerant flow controls and accessories, and mechanical and electrical control devices based on specifications, industry standards and manufacturer catalogues to determine calculated and deemed-to-comply solutions and documenting selection information. The skills and knowledge described in this unit may, in some jurisdictions, require a licence or permit to practice in the workplace subject to regulations for undertaking refrigeration and air conditioning work. Practice in the workplace and during training is also subject to work health and safety (WHS)/occupational health and safety (OHS) regulations.
