    3. INSTALLATION 3.5.8 Water cooled condenser The heat pump in a DanX 2/3 HP may be fitted with a water-cooled condenser for transfer of surplus heat, which is not used for heating the supply air for the pool or sanitary water. The entry for the water pipes is at the bottom of the unit, where the condenser is placed.

    3.6.3 Electrical heating coil The power supply to the electrical heating coil will not be delivered by the DanX 1/2/3, but must come separately from the building site. The 2-10V control signal (INT/GND/CTR) must be connected to the electrical panel, where the valve actuator is normally installed and the alarm contact (1/2) where the frost thermostat is connected.
