Installation, relative system connections, commissioning and verification of correct operation must be carried out correctly by professionally
qualified and trained personnel in full compliance with current national, regional, provincial and municipality regulations in the country
where the appliance is installed.
Size the system correctly to avoid long pause times that would cause significant problems like the ones mentioned in the section regarding
