Training & Support We offer free training and technical support to professional installers and distribution partners in both Ireland and the UK. Before using our equipment we insist all professional installers complete a product induction course and are certified to install HKC products. Training can be carried out at our state of the art training centre in Dublin or on-site. We offer a free technical support telephone service to answer questions from professional installers in the field. Our hours of operation are office hours Monday to Thursday 8:30 to 5pm (3:30pm on Friday). We don’t operate a voice prompt or menu option telephone system – an operator will always answer.
