Installation The accumulator tank should stand on a solid surface and be leveled with assistance from the setscrews underneath the tank. The tank models that come without setscrews can be leveled with assistance of a shim. This must be done before the tank is connected to the pipes and filled with water. Connections not in use must be plugged appropriately. During water filling, condensed water may emerge on the outside of the tank. This will result in water underneath the tank, on the floor. This will cease when the tank is heated. There must be a floor drain in the same room.
Commissioning
Start by filling the tank, then pressurize it. Continue to fill the radiator system (the enclosed water). The working pressure may not exceed 3 bar (gauge), a safety valve with a releasing pressure of 3 bar must always be installed.
Maintenance Check the safety valve annually by manually opening and closing the valve handle and making sure that water is released. Check annually all connections for eventual leakage (also peripheral installations, i.e. a heat pump, etc).
Electrical Installation
• The electrical installation must be performed by an authorised installer and follow applicable norms and regulations.
• When selecting electrical equipment, it must be selected with approved materials and enclosure class.
