It can be necessary to position the capillary tube before the equipment is insulated.”
Add the following subclause:
“11.101 Protection of hot and cold water services
Back-siphonage from the equipment to the potable water services shall be prevented by means
meeting the relevant requirements of EN 61770.
NOTE Attention is drawn to the existence of national and local regulations.
If the means are to be provided by the RESPONSIBLE BODY, this shall be stated in the manufacturer’s
installation instructions.
Conformity is checked by inspection and by examination of the manufacturer’s instructions.”

Annex A
(normative)
Safety requirements for components and piping
A.1 Overview
The sealed system components can be considered pressure vessels in accordance with the Pressure
Equipment Directive (PED) 2014/68/EU according to the classification in Table CC.1 and Table CC.2.
If the components or piping are classified as a Category II or higher pressure vessel according to the
PED, then the requirements of Table CC.3 shall apply including the use of a Notified Body to the PED.
