References to menu options in the heat pump’s control system are in upper case, e.g.: INFORMATION ->OPERAT.
  • Page 6 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. This valve is located in the water tank and may not be used for any purpose other than connecting the outlet pipe.
  • Page 7 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.
  • Page 8 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...
  • Page 9 Commissioning Caution! The installation may only be commissioned if the heating system and brine system have been filled and bled. Otherwise the circulation pumps can be damaged. 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.

  • Page 30 Necessary service space for outdoor unit. 4.12 Recommended location of outdoor unit, DHP-A, DHP-AL When positioning the outdoor unit, note the following: Caution! When the outdoor unit is defrosting, water will drip straight down under the unit. The area around the outdoor unit must therefore be properly drained in order to take the water (approximately 2 litres per defrost).
  • Page 31 Drilling holes for brine pipes Caution! Ensure that the holes for the insert pipes are positioned so that there is room for the other installations. Caution! The brine pipes shall have separate lead-ins. If the wall lead-ins are below the highest ground water level watertight lead-ins must be used.
  • Page 32 Separating the heat pump Note! Does not apply to DHP-L, DHP-L Opti, DHP-AL, DHP-AL Opti. If there is a shortage of space when transporting the heat pump to the installation location it may be necessary to separate the heat pump unit and the water heater. The following instruction describes how a heat pump is separated to transport the separate parts more easily.

  • Page 52 Noise information 8.6.1 Flexible hoses Caution! The press sleeves may never be used as a counterhold when tightening connections. All pipes should be routed in such a way that vibrations cannot be transmitted from the heat pump through the piping and out into the building. This also applies to the expansion pipe. We recommend that flexible hoses are used for all pipe connections to avoid the transmission of vibrations.
  • Page 53 • Ensure that all pipes are elastically suspended, with mountings as illustrated or similar. This is so that the rubber (or similar material) compresses 1 to 2 mm under vibration. It is not recommended to suspend the pipes from too many points, as the force at each mounting is then not sufficient. Figure 54.
  • Page 54 Filling the water heater and heating system Fill the water heater with cold water by opening the filler valve that is on the valve pipe. Bleed by opening one of the hot water taps. Then fill the water heater coil and the heating system with water through the filling valve to a pressure of approx.
  • Page 55 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.

  • Page 61 Brine installation 10.1 Heat sources 10.1.1 Bedrock heat To use rock as the heat source one or more boreholes is/are drilled and the brine hose is lowered into it/them. The hole is filled with water and a fitting with a weight is fastened to the hose before it is lowered. Figure 59.
  • Page 62 10.1.2 Lake heat When lake water is used as the heat source one or more brine coils is/are submerged in the water . The coils must be anchored to the bottom with weights or a net to prevent them floating. Figure 60.
  • Page 63 When ground water is used as a heat source the heat pump installation must be equipped with a flow sensor (available as an accessory) that stops the heat pump if the flow in the brine line is too low, which can create a risk of freezing in the ground water exchanger.
  • Page 64 Air heat The DHP-A andDHP-AL heat pumps are equipped with an outdoor unit that uses outdoor air as a heat source. DHP- AL can make use of the energy in the air outdoors down to temperatures of -20 degrees. To obtain the correct airflow through the outdoor section it is equipped with a fan.

  • Page 95 Important parameters 15.1 Heat production - calculating The indoor temperature is adjusted by changing the heat pump’s heat curve, which is the control system’s tool for calculating what the supply temperature should be for water that is sent out in the heating system. The heat curve calculates the supply temperature depending on the outdoor temperature.
  • Page 96 Position Description Set value (standard 40°C). In the event of outdoor temperatures below 0°C, a higher setpoint value is calculated and in the event of outdoor temperatures greater than 0°C, a lower setpoint value is calculated. -2 0 Figure 80. Increasing or reducing the CURVE changes the slope of the curve.
  • Page 97 • When changing the CURVE value, the angle of the curve on the system's heat curve changes. -2 0 Figure 81. Changing the ROOM value changes the heat curve upwards or downwards. Position Description Supply temperature (°C) Maximum supply temperature Outdoor temperature (°C) The relationship of the supply temperature to the outdoor temperature will not be affected.
  • Page 98 15.7 INTEGRAL The heat demand in the house depends on the season and weather conditions and is not constant. The heat demand can be expressed as temperature difference over time and can be calculated giving an integral value as a result (heat demand).
  • Page 99 Symbol explanation INTEGRAL A3 External auxiliary heater The calculation of the integral value stops during heat stop. The calculation of the integral value stops when heat stop has stopped. In this example INTEGRAL A3 < INTEGRAL A2. This means that the external addition will be activated earlier than the internal addition.
  • Page 100 The two parameters that are mainly changed are DEFR CURVE 0 and DEFR CURVE -20. The numbers behind the DEFR CURVE display what outdoor temperature the setting is for, that is to say at 0°C for DEFR CURVE 0 and -20°C for DEFR CURVE -20.
  • Page 101 Adjustable value for DEFR CURVE -20 is 1°C to 8°C lower than OUTDOOR STOP These three settings together create the defrosting curve and all three values have an effect on when defrosting will start, even if it is mainly DEFR CURVE 0 and DEFR CURVE -20 that is changed.

  • Page 102 Start up Note! Read the safety instructions! Caution! The installation may only be commissioned if the heating system, water heater and brine system have been filled and bled. Otherwise the circulation pumps can be damaged. Caution! Any alarms that may occur in connection with the installation must be fault-traced. Caution! If the installation is only to provide heat by an auxiliary heater during the installation, ensure that the heating system is filled and bled and the compressor cannot be started.

  • Page 106 Noise is produced from the outdoor unit when the fan is in operation, check during that manual operation that there is no disturbance in your own home as well as to any neighbours. A noise kit is available for purchase for the outdoor unit for DHP-A 10 and 12 if it is necessary to reduce the noise. 17.2.2 Select operating mode Set the heat pump to the desired operating mode in the menu INFORMATION ->...
  • Page 107 17.3 Installing the front cover Caution! Take care not to damage the front cover or display cables! Hook on the lower edge of the front cover. Carefully press the front cover’s upper edge towards the heat pump. Turn the catch in the top panel 90 degrees clockwise. 17.4 After start up Note! Remember that it takes time for the heat pump to heat a cold house.
