2 Important information/Safety regulations Warning! Risk of personal injury! Children are not permitted to play with the product. Warning! As the water temperature in DHP-H Opti Pro and DHP-L Opti Pro becomes extremely hot, a mixer valve must be installed between the cold water and hot water pipes to ensure a lower domestic hot water temperature.Alternatively the maximum hot water temperature must be reduced in the Service menu.
Caution! The hot water tank must be equipped with an approved safety valve. Caution! Heating systems with closed expansion tanks must also be supplied with approved pressure gauges and safety valves. Caution! Cold and hot water pipes and overflow pipes from safety valves must be made of heat resistant and corrosion-resistant material, e.g. copper. The safety valve overflow pipes must have an open connection to the drain and visibly flow into this in a frost-free environment.
Warning! Risk of personal injury! Refrigerant exposed to a naked flame creates a poisonous irritating gas. This gas can be detected by its odour even at concentrations below its permitted levels. Evacuate the area until it has been sufficiently ventilated. 2.1.3 Work on the refrigerant circuit Caution! When repairing the refrigerant circuit, the refrigerant must not be released from the heat pump, it must treated in the appropriate way.
Caution! If the installation is only to be driven by an auxiliary heater during the installation, ensure that the heating system is filled and the brine pump and compressor cannot be started. This is carried out by setting the operating mode to AUX. HEATER.

4 Transport, unpacking and setting-up 4.1 Transporting the heat pump Caution! During transportation or lifting of the entire heat pump, the front panel must always be installed as it locks the other panels construction. Caution! The heat pump must always be transported and stored in a dry area. Secure the heat pump so that it cannot tip over during transportation. When transporting indoors to the installation location it may be necessary to place the heat pump on its back.
Avoid positioning the heat pump in a corner as the surrounding walls may amplify its noise. It is also important to adjust the heat pump using the adjustable feet so that it is horizontal to the base. 4.3.2 Space requirement Caution! The heat pump must not be enclosed as the temperature inside the cabinet becomes extremely high.

5 Piping installation Warning! As the water temperature in DHP-H Opti Pro and DHP-L Opti Pro becomes extremely hot, a mixer valve must be installed between the cold water and hot water pipes to ensure a lower domestic hot water temperature.Alternatively the maximum hot water temperature must be reduced in the Service menu. Warning! Danfoss SP (1-phase) heat pumps have a factory installed safety valve for temperature and pressure, (10 bar 90-95°C), in accordance with the requirements in Great Britain.
5.2 Connection heat transfer fluid 5.2.1 System solution 1 In system solution 1 the heat pump can produce both heating and hot water with the compressor and the integrated auxiliary heater. Production of heating and hot water cannot occur at the same time because the exchange valve for heating/hot water is positioned after the auxiliary heater. The integrated auxiliary heater carries out peak heating charging (antilegionella function) in those operating modes that permit auxiliary heat.

5.2.1.3 Example system solution 1 System solution for DHP-L Opti Pro. Symbol explanation Figure 18.
5.2.2 System solution 2 In system solution 2, the heat pump can produce both heat and hot water and an external auxiliary heater (oil boiler, electric boiler, district heating or similar) supports heat production but not hot water production. The exchange valve for heating/hot water is located ahead of the external auxiliary heater, which allows the production of heating and hot water at the same time.

The brine pipes running outside the house to the collector can be buried, however they must be well insulated.
used for all pipe connections to avoid the transmission of vibrations. Flexible hoses are available to purchase as accessories. The figures below show how appropriate and inappropriate installations look using this type of hose. To avoid noise caused by pipe mounting, a rubber-coated pipe clamp should be used to prevent the transmission of vibrations. However, installation should not be too rigid and the pipe clamp must not be too tight. Figure 34. Do not twist the flexible hoses as they are installed.
6 Electrical Installation DANGER! Electrical voltage! The terminal blocks are live and can be highly dangerous due to the risk of electric shock. All power supplies must be isolated before electrical installation is started. The heat pump is connected internally at the factory, for this reason electrical installation consists mainly of the connection of the power supply.

10.7.2.1 Noise check During transportation and installation there is a certain risk that the heat pump can be damaged, components may move or get bent and this can cause noise. Because of this it is important to check the heat pump when it has been installed and is ready to be commissioned to ensure that everything is in order. The heat pump should be tested in both heating and hot water modes to ensure that there is no abnormal noise.
6. 7. 8. 9. 10.9 Adjust the ROOM value so that the reference room reaches your required indoor temperature of 20-21°C. Remember that other rooms will have different temperatures during trimming, but these are adjusted later. If the ROOM value must be adjusted more than 3°C upwards or downwards the CURVE value must be adjusted instead. See Adjusting CURVE values for more information. If the indoor temperature varies several degrees despite trimming, a specific part of the heat curve may need adjusting.
