Page 5: About The Instructions
About the instructions Introduction The installation instructions start by describing heat pump data. The installation instructions later give instructions in a logical order covering unpacking, installation procedure, and checking the installation. References to chapters and sections within the instructions are in italics, e.g.: About the instructions. References to menu options in the heat pump’s control system are in upper case, e.g.: INFORMATION ->OPERAT. -
Page 6: Important Information
Important information Caution! The heat pump must be located in a frost-free environment! Caution! The power supply must be disconnected during service and before changing parts in the appliance. Caution! The installation may only be commissioned if the heating system is filled and bled. Otherwise the circulation pump can be damaged. -
Page 7: Noise And Vibrations
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. Warning! Risk of personal injury! Anyone with symptoms of poisoning from the vapour must immediately move or be moved into the fresh air. - Page 8 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 1. Do not twist the flexible hoses as they are installed. At threaded connections, use a counterhold spanner Figure 2.
- Page 9 • 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 5.
- Page 10 Electrical current! DANGER! The terminal blocks are live and can be highly dangerous due to the risk of electric shock. The power supply must be isolated before electrical installation is started. The heat pump is internally connected at the factory. 8 –...

Page 15: Drilling Holes For Brine Pipes
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 16: Unpacking And Installation
Unpacking and installation The heat pump is packed in boxes and wrapped in cardboard and delivered on a wood pallet. Check that the delivery is complete and undamaged. Caution! When moving the heat pump, do not use the protruding pipe connections to lift the heat pump. The packaging should not be used to lift the heat pump either. - Page 17 Symbol explanation Screws Front panel Figure 12. Remove the front cover Installation instructions VMIFJ102 – 15...

Piping installation Caution! To prevent leaks ensure that there are no stresses in the connecting lines! Note! Ensure that the pipe installation is carried out in accordance with the dimensions and connection diagrams. Note! Pipe installation must be carried out by an authorized installer. Caution! It is important that the heating system is bled after installation. -

Electrical Installation Electrical connection Caution! Electrical installation may only be carried out by an authorized electrician and must follow applicable local and national regulations. Caution! The electrical installation must be carried out using permanently routed cables. It must be possible to isolate the power supply using an all-pole circuit breaker with a minimum contact gap of 3 mm. -
Page 21: Connecting Sensor For Outside Temperature
Connecting sensor for outside temperature Position the outdoor sensor on the north or north west facing side of the house, away from direct sunlight. The outdoor sensor should not be placed on reflective panel walls. The sensor must be positioned at least 1 m from openings in the walls that emit hot air. - Page 22 Table 4.

Page 23: Test Operation
Test operation 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. -

Menu information Menu description regards software with version 1.3. The heat pump has an integrated control system which automatically calculates the heat demand in the house to ensure that the correct amount of heat is produced and emitted where necessary. There are many different values (parameters), which are required in order to do the calculation of the heat demand. -

The heat curve can be changed by adjusting the CURVE value. The CURVE value indicates the supply temperature of the water that is wanted to the heating system at an outdoor temperature of 0°C.
- Page 40 11.2.3 ROOM If you wish to increase or reduce the indoor temperature, change the ROOM value. The difference between changing the ROOM value and the CURVE value is as follows: • When changing the ROOM value, the angle of the curve on the system's heat curve does not change, instead the entire heat curve is moved by 3°C for every degree change of the ROOM value.
- Page 41 11.2.6 TEMPERATURES The heat pump can display a graph showing the history of the various sensors’ temperatures and you can see how they have changed over 60 measurement points in time. The time interval between the measurement points can be adjusted between one minute and one hour, factory setting is one minute.
