When installing on the door frame from the closing side, in order to avoid unintentional loosening of the screw securing the rod to the closer body and, as a result, damage to the rod itself, it is imperative to use a groover (included in the delivery set) and, recommended, a thread lock.

When installed on doors located outside the premises, the closer must be under a canopy to avoid moisture ingress (the closer's rod is steel).

When adjusting the speed valves (available on all models), the tensioners, as well as the opening brake and closing deceleration valves (on models where they are available), carefully monitor the degree of unscrewing (counterclockwise). The valve should not be unscrewed more than the plane of the tensioner body.
Otherwise, fluid (oil) may leak from the tensioner during operation and, as a result, air in the tensioner. This cannot be considered a warranty case.
