• The drip can be piped to the drain by installing a tundish just below the safety valve.
• The drain installed below the safety valve outlet must be piped down vertically and placed
in an environment that is free from the onset of freezing conditions.
• To avoid water dripping from the safety valve, an expansion tank should be installed on the
inlet pipe of the heater with the capacity of at least 5% of the heater volume.
• To ensure proper operation of the safety valve, periodical inspections must be carried out
to remove limescale and make sure the safety valve is not blocked.
• To check the valve, open the outlet of the safety valve by turning the handle or unscrewing
the nut of the valve (depending on the type of the valve).
• The valve is operating properly if the water comes out of the nozzle when the outlet is
open.

pressure relief valve
Before connecting it to the power supply, the Aquapoint must
be filled with water
•
When filling the heater for the first time, the tap for the hot water on the mixing tap must be
opened.
