Fundamentals of Inverter Air Conditioners

Course Overview

The course includes an induction session to welcome and orientate the candidate, and familiarize them with the training centre, health and safety requirements and other important policies and procedures. The training consists of a mix of classroom and workshop sessions and various assessments. Upon successful completion, the candidate will gain the knowledge and understanding to work on the installation, service, maintenance, recovery, leak checking, gas charging, new Gas-410a of stationary Inverter air conditioner.

The course is designed to upskill the engineering technicians working within their trade discipline or appreciating another, where knowledge and understanding may be required.

The candidate should have basic knowledge of Non-inverter Air Conditioning Systems.

Upon completing the training course, candidates will be awarded a ‘Certificate of Attendance’ from NTI, attested by the Ministry of Manpower.
