This new IOR Technical Committee guidance note outlines the legal requirements of the Pressure Equipment (Safety) Regulations - PE(S)R and Pressure Equipment Directive (PED) for installers of RACHP systems.
In the RACHP sector components are supplied by a manufacturer for site installation by a specialist third party contractor who might not realise that they have the responsibilities of the manufacturer of the assembly under PE(S)R.
With the move to R32 and other A2L refrigerants, classified as PE(S)R group 1 fluid (“dangerous”), this moves many systems from SEP (sound engineering practice) or hazard category 1 into hazard category 2 or higher. Systems which are category 2 or higher must comply with the PE(S)R and must be assessed by an approved Conformity Assessment Body or under an assessment scheme which has been certified by a Conformity Assessment Body.
