This Course is designed to cover the Safe Isolation of electrically powered or controlled equipment, identifying types of Instrumentation used in Installation and Testing, develop an understanding and interpretation of the essential Regulations applicable to working with electricity.

Topics Include

In addition the Course is constructed to make delegates aware of common Supply Systems and Earthing Arrangements, enabling an understanding of Control and Protection Equipment, Earthing and Bonding Requirements, Terminating and Installation Practices with an emphasis on Electrical Safety. Electrical Concepts, Safe Isolation Methods, Instrumentation, Electrical Regulations, Supply Systems, Earthing and Bonding, Termination Skills, Electrical Safety and Electrical Controls. Together with learning how to recognise and calculate electrical quantities and identify common supply system arrangements, deligates will further boost their skill set with the objectives listed below.

Objectives

Measure Voltage, Current and Resistance values. Identify any possible contraventions of The Electricity at Work Regulations. Safely isolate electrical equipment and circuits. Survey an installation for Electrical Bonding. Install permanent and temporary Continuity Bonding Conductors. Terminate electrical cables and flexible cords to appliances and equipment. Verify the safe and correct operation of Electrical Control Devices. Perform Electrical Safety Checks and Tests on appliances and equipment.

Who should attend?

This Course is designed for the non-electrically trained Installation and Service Personnel who are required to make electrical connections to and test water heaters, central heating boilers and air conditioning and refrigeration equipment. It will also serve as a refresher to those who are already experienced in the installation of electro mechanical plant requiring to meet the latest Regulations. The Course would also serve as useful to those managing Service Personnel with a view to ensuring Safe Working Practices are adhered to.

This Course aims to improve, enhance and update the skills of both lesser and well experienced engineering personnel. The theory and practical aspects of the subjects are covered in detail and, where applicable, exercises are undertaken to develop the necessary skills.

Topics include

Subjects include installation, commissioning, service, repair, fault diagnosis, evacuation, dehydration, refrigerant charging and refrigerant recovery. Emphasis is given to good standards, professionalism and saving time. Where applicable, new regulations and standards are introduced such as European recommendations for refrigeration pipework design to ensure safe handling of CFC’s.

Objectives

At the end of the Course delegates will be able to:
Undertake refrigerant pipework design and apply correct pipework installation practice.
Commission air conditioning and refrigeration systems to a professional standard.
Apply effective equipment servicing and repair techniques.
Undertake system evacuation, dehydration, precision charging and proper refrigerant recovery.

Who should attend?

A detailed Course suited to those who have an understanding of air conditioning and refrigeration theory and equipment, including Installation & Service Engineers, Plant Maintenance Staff, Supervisors, Service Managers, Design and Application Engineers, Sales Engineers, Building Services Engineers and anyone who has responsibility for overseeing or accepting work done on air conditioning or refrigeration systems. This is an excellent refresher Course and is useful as preparatory training for the C.I.T.B. Refrigerant Safe Handling Registration Course.

Leading to ConstructionSkills Certification & Registration (Valid for 5 years). A two-day Course leading to the ConstructionSkills Pipework and Brazing Competency Certification.

Topics include

This Course commences with a theoretical session followed by a short written assignment. It is predominately a practically orientated course covering both Air Conditioning and Refrigeration requirements for safe and competent brazing (copper/copper, copper/brass, copper/steel) techniques. A range of differing copper line sizes will be applied including the use of different materials and brazing alloys, all leading to quality leak-proof joints. New refrigerants and their specific techniques will be discussed, equipping the Engineer/Technician with up to date information and the current legislation requirements.

Objectives

At the end of the Course delegates will be able to:
1 Produce quality brazed joints on differing pipe sizes.
2 Be aware of the industry needs related to jointing methods.
3 Demonstrate competency by showing the CITB certification card.
4 Make others aware of the need for sound brazing techniques.

Who should attend?

Engineers/Technicians presently carrying out installation or assembly work associated with Pipework and Brazing, within the Air Conditioning and Refrigeration industries. Trainees are ideally suited to this Course leading to Competency Certification.

New training courses have been introduced to meet the legal requirement of EC Regulation 842/2006 (commonly known as the F-Gas Regulation) leading to ConstructionSkills Certification & Registration (valid for 5 years) and Voluntary ACRIB Registration.
