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

This unit involves the skills and knowledge required to select residential air conditioning system equipment, components and accessories.

It includes selecting residential air conditioning equipment, pipe work, air distribution components and controls. It also includes selecting the unitary air conditioning equipment and components, system controls, refrigerant and condensate pipe work based on specifications, industry standards and manufacturer catalogues to determine calculated and deemed-to-comply solutions and documenting all 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.

No other licensing, legislative or certification requirements apply to this unit at the time of publication.
