Maintenance and Leak Testing

Introduction

In order to obtain full efficiency and reliability, correct maintenance procedures are essential. In addition, it is now becoming mandatory to carry out regular leak tests on refrigeration plants.

The Maintenance course, combined with City & Guilds Category 4 Leak Testing provides maintenance staff with an insight into the principles of refrigeration, the correct operation of the system to optimise running costs and the skills and knowledge to carry out routine leak tests on refrigeration plant. the City and Guilds 2079 Category 4 Leak Testing assessment will be taken at the end of the course.

Objective

To attain a basic understanding of the principles of refrigeration and diagnosis of common faults and acquire the knowledge and practical skills necessary to achieve an F Gas Category 4 qualification in Leak Testing (City and Guilds 2079 category 4)

Methodology

For the Maintenance section, the topics will be covered with a mixture of practical observation and practical work by the candidate using fully operational systems. Theoretical work will be assisted by the use of good quality visual aids and discussion sessions.

For the leak testing, theory will be covered by means of a presentation and discussion session. Practical work will be carried out on real working systems. A full set of course notes will also be provided.

The assessment is a mixture of theory and practical. Theoretical knowledge is tested by means of an on-line, multiple choice question paper. Practical aptitude is tested by means of a practical assignment.
