    Dimensions and pipe SYSTEM DIAGRAM F370 consists of a heat pump, water heater, immersion connections heater, fan, circulation pump and control system.F370 is connected to the ventilation system and heating medium circuits. When the exhaust air at room temperature passes through the evaporator, the refrigerant evaporates because of its low boiling point.

    Exhaust air duct (kitchen fan) must not be connected to F370. To prevent cooking odours from being led to the F370, the distance between the kitchen fan and the exhaust air valve must be taken into consideration. The distance must not be less than 1.5 m, but may vary between different installations.
