Make sure you wait before performing any work in the heat pump after turning off the power, because the unit contains capacitors which may be charged. Do not start the unit ( Maxi) if there is a possibility of frozen water in the immersion heater. Caution When cooling, it is important to limit the lowest flow line temperature to prevent condensation. Danfoss Heating Solutions VIJSQ102 7
2.2 Refrigerant 2.2.1 Refrigerant Caution Work on the refrigerant circuit must only be carried out by a certified engineer! Although the heat pump cooling system (refrigerant circuit) is filled with a chlorine-free and environmentally-approved refrigerant that will not affect the ozone layer, work on this system may only be carried out by authorized persons. 2.2.2 Fire risk The refrigerant is not combustible or explosive in normal conditions. 2.2.3 Toxicity In normal use and normal conditions the refrigerant has low toxicity. However, although the toxicity of the refrigerant is low, it can cause injury (or be highly dangerous) in abnormal circumstances or where deliberately abused. Warning Risk of personal injury! Spaces in which heavy vapor can collect below the level of the air must be well ventilated. Refrigerant vapor is heavier than air and, in enclosed spaces below the level of a door for example, and in the event of leakage, concentrations can arise with a resultant risk of suffocation due to a lack of oxygen. Warning Risk of personal injury! Refrigerant exposed to a naked flame creates a poisonous irritating gas. This gas can be detected by its odor even at concentrations below its permitted levels. Evacuate the area until it has been sufficiently ventilated. 2.2.4 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. Draining and refilling must only be carried out using new refrigerant (for the amount and type of refrigerant see manufacturer s plate) through the service valves. 8 VIJSQ102 Danfoss Heating Solutions
Caution All warranties from Danfoss are void if, when filling with refrigerant other than not valid specified refrigerant, if there has not been written notification that the new refrigerant is an approved replacement refrigerant together with other remedies. 2.2.5 Scrapping Caution When the heat pump is to be scrapped the refrigerant must be extracted for disposal. Local rules and regulations related to the disposal of refrigerant must be followed. 2.3 Commissioning Caution The installation may only be commissioned if the heating system has been filled and bled. Otherwise the circulation pump can be damaged. Caution If the installation is only to be driven by the immersion heater during the installation, ensure that the heating system is filled and compressor cannot be started.

3.8 Distribution circuits The only use for a mixing valve is in a heating system with an external heat source (an oil burner or equivalent) or where there are more than one heating circuits, for example a mix of radiator and underfloor heating. There are three available mixing valve options: Mixing valve (Activation, see chapter "Activate the external auxiliary heater in Mini") Distribution circuit (DISTR. CIRCUIT) 1 Distribution circuit (DISTR. CIRCUIT) 2 (Requires expansion card) The mixing valve is used between the heat pump, an external auxiliary heater (may be an oil burner or equivalent) and the heating system. The purpose of this valve is to mix cold water into the heated water from the external auxiliary heater (on/off heater) to ensure that the temperature out on the heating system is not too high. The control system in the heat pump controls the mixing of hot and cold water out on the heating system. Distribution circuits 1 and 2 are used where there are more than one heating circuit, for example a mix of radiator and underfloor heating. The purpose of these distribution circuits are to supply a preset temperature to each one of the heating circuits. Activating DISTR. CIRCUIT 1 The following settings are made in the Service Menu. If not already in the Service Menu, enter the Service Menu by pressing and holding left arrow (<) for at least 5 seconds. Use + or to move up and down in the menu.

Press + to activate the optimum function. O will appear to confirm the setting. 16 VIJSQ102 Danfoss Heating Solutions
4 Find min. flow 4.1 Finding the min. flow Finding a sufficient flow in order to activate the flow switch can be done in the following ways: Automatically, using the FID MI. FLOW parameter Manually, setting the START FLOW CIRC. value for the optimum circulation pump Make sure to activate all functions to be affected, before you start the detection sequence! If any functions are activated after the FID MI.FLOW sequence is done, they will have their respective default setting. For Mini, with fixed speed circulation pump, the flow has to be set from MAUAL TEST. Make sure the "F" symbol is present in the display after finishing the test. If not, check the system for air, and that the flow switch is correctly installed. Also consider if the size of the circulation pump is sufficient for the system. 4.1.1 Find min. flow automatically This option is only valid for a heat pump model with the optimum function. If the operation mode is set to cooling, perform the min. flow search on the heating system, not on the water heater. The flow will automatically be adapted to the water heater. To be able to automatically search for a min. flow, the following is required: The installation must be completed and checked. The heating system and water heater must be filled and bled. The configuration of the control system must be completed. The heat pump must be in operation OFF mode with the OFF symbol ( ) shown in the display. Manual test must be deactivated (0). Heating, hot water and/or cooling must be activated in the configuration. The following settings are made in the Service Menu. If not already in the Service Menu, enter the Service Menu by pressing and holding left (<) arrow for at least 5 seconds. Use + or to move up and down in the menu. Danfoss Heating Solutions VIJSQ102 17
Find the min. flow in the menu: SERVICE OPTIMUM FID MI. FLOW Press right arrow (>) to enter the FID MI. FLOW menu. The off symbol ( ) is shown. Press right arrow (>) to activate the FID MI. FLOW menu. Press + to activate the FID MI. FLOW menu. O will appear in the display to confirm the setting. Depending on the configured functions, the result of the flow search may be presented as follows: Operation mode Heating If the function for heating is activated, the result will be one of the following: HEAT FLOW OK HEAT FLOW OT OK If the flow is not OK, measures must be taken to ensure sufficient min. flow, for example, make sure the system is properly bled on air, install an additional circulation pump or other equipment, such as a buffer tank, that will increase the flow enough. Operation mode Hot water If the function for hot water is activated, the result will be one of the following: H.W FLOW OK H.W FLOW OT OK If the flow is not OK, measures must be taken to ensure sufficient min. flow, for example, make sure the system is properly bled on air, install an additional circulation pump or other equipment, such as a buffer tank, that will increase the flow enough. Operation mode Cooling If the function for cooling is activated, the result of the flow search may be as follows: COOLIG FLOW OK1 = Flow is sufficient for defrost. COOLIG FLOW OT OK1 = Flow is not sufficient for defrost. or; COOLIG FLOW OK2 = Flow is sufficient for cooling. COOLIG FLOW OT OK2 = Flow is not sufficient for cooling. If the flow is not OK, measures must be taken to ensure sufficient min. flow, for example, make sure the system is properly bled on air, install an additional circulation pump or other equipment, such as a buffer tank, that will increase the flow enough. It may take a while before the search is completed and the result is displayed. You may continue with other parts of the commissioning that are independent of the search for a min. flow. Press left arrow (<) several times to navigate back to the Service Menu. 18 VIJSQ102 Danfoss Heating Solutions
The min. flow found in this procedure is the actual flow that exists in the current configuration of the system. Seasonal variations with different temperatures may alter the behavior of the system and this may affect the flow as well. For example, automatic radiator valves may open or close depending on the temperature. 4.1.2 Find min. flow manually This setting is a manual alternative to the FID MI. FLOW function which runs automatically when activated. The start flow is maintained for one minute. After one minute, the circulation pump and control system takes over the speed control. Default setting: 7V, range: 3V 10V (30-100%) The following settings are made in the Service Menu. If not already in the Service Menu, enter the Service Menu by pressing and holding left (<) arrow for at least 5 seconds. Use + or to move up and down in the menu. SERVICE OPTIMUM START FLOW CIRC. Press + to set the start circulation pump speed. See note below. Press left arrow several times to exit the SERVICE MEU Start with a high setting, for example 10V. Check that the circulation pump is running by listening, placing a hand on the circulation pump and listen for air in the system. If no flow is registered at 10V, check the system for air and bleed if necessary. See chapter "Filling and bleeding". Also check that all heat system valves are open. If flow is detected, normally within 60 seconds, decrease the setting by 10% (1V) until the flow is so low that the F in the default display disappears. (You must exit the SERVICE MEU and enter the default display for each decrease in speed) ote the last reading for the F in the display and increase that value by 10%. This value is to be used as a setting in START FLOW CIRC. Danfoss Heating Solutions VIJSQ102 19
