  • Page 4: Recommendations

    1 - RECOMMENDATIONS - The cover of this device must never be used for carrying or handling and is not designed for this purpose. - Rinse piping before connecting the device to the domestic hydraulic system. - This device only functions when filled with water. Never activate the device unless the tank is completely full and properly primed.

    2 - INSTALLATION 2.1 Dimensions 2.2 - Placement 2.2.1 - Air Intake To be considered when choosing the final placement: • D.W.H.P must not be installed outdoor • D.W.H.P must be installed in a room outdoor from frost. Also, the temperature of the air taken in must range between -5°C and 35°C.

  • Page 6: Installation With Air Duct

    2.3 - Installation with air duct In cases of connection with ducts, it is necessary to set the ventilation speed 2 (see section “PAR.06 – Ventilation speed”) Outdoor air Heated or unheated room 0,5 m mini 2 m mini 2.4 - Air duct sizing The connection of D.W.H.P must be done using insulated air ducts of a nominal diameter of 160mm.
  • Page 7 In consequence, the connection of the device to the copper piping of the domestic hot water should ALWAYS be carried out via a cast iron fitting, or steel, or with the help of dielectric connections (not included) which will help to avoid any iron/copper galvanic bridge. •...
