2.8 Connection of water-cooled condenser

To lead away any excess heat from the unit, a water-cooled condenser may be fitted allowing transfer of the excess
heat to the pool water instead of the room air.
CDP 75, 125 and 165 with water-cooled condenser are supplied with cupper coupling pipes (Ø15 mm). The
coupling pipes can be coupled together with PEX pipes by means of clamping ring fittings in cases where copper
pipes are not required.
The condenser is normally activated by a temperature controlled pool water pump, which starts up automatically
above a specified room temperature and pumps pool water through the condenser.
The inflow is connected with the connector marked "IN" and the outflow with the connector marked "OUT".
The technical specifications for the water-cooled condenser are shown in the table on page 45.

2.9 Connection of defrosting sensor

If the CDP 75/125/165 are used in the temperature range between 15 and 20°C the evaporator coil should be
protected by a sensor. The defrosting sensor is fixed in points 15 and 16 on the PCB terminal. DIP Switches 3 and
6 are set on ON and the sensor is placed in the sensor pocket of the evaporator coil.
The defrosting sensor is available as options on request.

3. Connection of power supply

Power is connected to the unit in accordance with the name plate. Please refer to the wiring diagrams on pages 48.

4. Operation

4.1 LP/HP pressostat and thermal relay for compressor protection

The CDP 75, CDP 125 and CDP 165 are fitted with a reset button of the HP pressostat on the inspection side.
The CDP 125(3x400V) and CDP 165(3x230V/3x400V) are additionally fitted with a reset button for the thermal
relays. This protects the compressor.
The compressors in CDP 75(1x230V) and CDP 125(1x230V) are protected by a Klixon and not by a thermal relay.
NOTE! All electrical connections must be made in
accordance with local power supply
company regulations.
