Split and multi split system design and specification (LG RAC and Universal range)

MULTI V_Outdoor unit Line up

This course includes all non VRF LG air conditioners. It covers the information required to specify LG air conditioners for a particular site. It is intended for sales engineers, consultants and others who are involved in preparing specifications and quotations. It also includes an overview of the control systems available for this range.

VRF system design and specifications

The course is for consultants, sales engineers, and others who need to specify and quote LG VRF systems. It covers all aspects of the design including pipe layout and sizing, electrical layout, and the components required to make up a system.

VRF installation and service

LG Air Conditioners System

This course covers the installation, commissioning and servicing of LG VRF systems including how they work and fault finding. It is intended mainly for experienced installation engineers. This course is 80 % practical based.

Split and multi split system installation and service (LG RAC and Universal range)
This course covers the installation and service of LG air conditioners, including how they work and fault finding. It is intended mainly for experienced air conditioning engineers. This course is 80% practical based.

Central controls

LG offers a range of central controls to provide control and monitoring of a large number of indoor units from a central location. The course concentrates on the installation and setting up of the AC smart (full control, monitoring and scheduling) and the Simple Central Controller (mainly on/off control). The course is 100% practical based.
As from April 9th, 2007 for CFCs and July 4th, 2007 for HFCs, it will be a compulsory requirement for any person who handles refrigerants or breaks into any refrigeration or air conditioning system, to have a safe handling of refrigerant qualification as an absolute minimum. Lg will be asking all trainees to confirm that they have this qualification before attending any of our installation or service training courses. If they dont have this we will be recommending to them that they should obtain this qualification as a matter of urgency. We reserve the right to refuse training to any engineers without this qualification.

Capacities are net capacities 3. Due to our policy of innovation some specifications may be changed without notification 4. When the calculated refrigerant charge is over 95kg, multiple outdoor system must be divided into smaller independent systems. So, each system contains less than 95kg refrigerant charge.
