REQUIREMENTS FOR FLAMMABLE REFRIGERANT Transport of devices containing flammable refrigerants: Compliance with transport regulations.
  • Page 7 Service Information: Area inspection. Before starting work on systems containing flammable refrigerants, safety checks are necessary to minimize the risk of ignition. When repairing a cooling system, the following safety guidelines should be observed before working on the system. Work procedure. Work should be carried out following a controlled procedure to minimize the risk of the presence of flammable gas or vapor during work. General work area. All service personnel and others working in the local area should be informed of the nature of the work being performed. Avoid working in confined spaces. The area around the work location should be secured. Ensure that the conditions in the area have been secured by controlling flammable materials. Checking for refrigerant presence. The area should be checked with the appropriate refrigerant detector before and during work so that the person performing the operation is aware of potentially flammable atmospheres. Ensure that the leak detection equipment used is suitable for use with flammable refrigerants, i.e., does not spark, is adequately sealed, or is intrinsically safe. Fire extinguisher. If any „hot work” is foreseen on refrigeration equipment or any associated part, appropriate firefighting equipment should be on hand. In the area where the heating agent is replenished, there should be a powder or CO2 fire extinguisher. No ignition sources. Any person carrying out work on the cooling system that involves exposing any pipe containing or having contained a flammable refrigerant in the past should not use any ignition sources in a way that could lead to a fire or explosion. All possible ignition sources, including smoking, should be kept at a sufficient distance from the installation, repair, disassembly, and disposal during which a flammable refrigerant may be released into the surrounding space. „No Smoking” signs should be posted before starting work. Ventilated area. Ensure that the location is outdoors or adequately ventilated before opening the system or starting any „hot work.” Ventilation should be maintained throughout the period when work is being carried out. The ventilation should safely disperse any released refrigerant and, preferably, exhaust it into the atmosphere. Inspection of cooling equipment. During the exchange of electrical components, they must be appropriate for the purpose and meet the relevant specifications. At all times, manufacturer guidelines for maintenance and service should be followed.
  • Page 8 Cables. Check that cables are not exposed to wear, corrosion, excessive load, vibrations, sharp edges, or other adverse environmental factors. When checking, also consider the effects of aging or continuous vibrations from sources such as compressors or fans. 10. Detection of flammable refrigerants. Under no circumstances should potential ignition sources be used to search for or detect refrigerant leaks. Do not use a halogen torch or another detector using an open flame. 11. Leak detection methods. The following leak detection methods are considered acceptable for systems containing flammable refrigerants. a) Electronic leak detectors should be used to detect flammable refrigerants, but their sensitivity may be insufficient or may require recalibration. b) Leak detection equipment should be calibrated in an area free of refrigerants. c) Make sure the detector is not a potential ignition source and is suitable for the refrigerant used. d) Leak detection equipment should be set to the percentage of the Lower Flammable Limit (LFL) of the refrigerant and should be calibrated to the refrigerant used, and an appropriate percentage of gas (up to 25%) should be confirmed. e) Leak detection fluids are suitable for use with most refrigerants, but detergents containing chlorine should be avoided as chlorine can react with the refrigerant and corrode copper pipes. . 12. Removal and evacuation. When dismantling a cooling system for repair or any other purpose, standard safety procedures should be followed, and the following procedure should be observed: a) Removal of the refrigerant; b) Circuit cleaning using inert gas; c) Evacuation; d) Recleaning the circuit with inert gas; e) Opening the circuit by cutting or soldering. The refrigerant charge should be recovered into appropriate recovery tanks. The system should be „flushed” with clean nitrogen (OFN) to ensure unit safety. This process may require repetition several times. Do not use compressed air or oxygen for this task. Flushing should involve breaking the vacuum in the system using clean nitrogen (OFN) and continuing filling to reach working pressure, then venting to the atmosphere, and finally re-evacuating to vacuum. This process should be repeated until no refrigerant is inside the system. After using the last OFN charge, the system should be vented to atmospheric pressure to allow work to be carried out. This operation is absolutely necessary if soldering work is to be carried out on the pipeline. Make sure the vacuum pump outlet is not near any ignition sources and ventilation is available. 13. Refilling the Heating Agent Procedures. In addition to conventional filling procedures, the following requirements must be adhered to: Ensure that there is no contamination by different refrigerants during the use of the filling equipment. Hoses should be as short as possible to minimize the amount of refrigerant contained in them. Cylinders should be kept in an upright position. Before filling the cooling system with refrigerant, make sure that the cooling system is grounded.
  • Page 9 g) Do not overfill the tank (no more than 80% volume of the liquid refrigerant). h) Do not exceed the tank’s maximum working pressure, even temporarily. i) Once the tank has been filled correctly and the process is complete, ensure the tank and equipment are promptly removed from the worksite, and all isolation valves on the devices are closed. j) Recovered refrigerant cannot be filled into another cooling system unless it has been purified and tested. 15. Labeling. Devices should be marked, indicating they have been taken out of use and emptied of the refrigerant. The label should be dated and signed. Make sure the device is labeled to indicate that it contains a flammable refrigerant. 16. Recovery. When recovering a refrigerant from a system, both for servicing and disposal, it’s recommended to safely remove all refrigerants. When transferring refrigerants to tanks, ensure the correct recovery tanks are used. Ensure an adequate number of tanks to store the total refrigerant quantity in the system. All used tanks should be designated for refrigerant recovery and marked as such (e.g., special refrigerant recovery tanks). Tanks should be equipped with safety valves and suitable closures that are operational. Empty recovery tanks should be cleared of air and, if possible, cooled before starting recovery. The refrigerant recovery equipment should be functional, with a full set of user instructions tailored to that equipment and suitable for recovering flammable refrigerants. Additionally, a calibrated working scale should be available. Hoses should be equipped with leak-tight quick couplings and be in good condition. Before using the recovery device, check its technical condition, ensure it has been maintained properly, and all its electrical components are tightly closed to prevent ignition in case of a refrigerant leak. If in doubt, consult the manufacturer. Recovered refrigerant should be returned to the refrigerant supplier in a suitable recovery tank along with the appropriate waste transfer document. Refrigerants should not be mixed in recovery units, especially in tanks. If compressors or compressor oils are to be removed, ensure they have been adequately cleaned of refrigerant to an acceptable level, ensuring that the flammable refrigerant does not remain in the lubricating oil. A dehydration process should be conducted before sending the compressor back to the supplier. Only electric heating of the compressor body should be used to accelerate this process. Safety precautions should be observed when draining oil from the system. 2.4. OTHER SAFETY ASPECTS As a heat source, the pump uses external air, generating energy to heat your home.

ADDITIONAL ACCESSORIES Each unit requires the user to purchase at least the following optional items for normal use.
  • Page 11 5. PRINCIPLE OF OPERATION 5.1. PRINCIPLE OF OPERATION OF THE HEAT PUMP Low-pressure heated refrigerant vapors from the evaporator are sucked in and compressed to form high-temperature, high-pressure vapors by the compressor. The heated vapor is directed to the condenser to exchange heat with water. The refrigerant condenses (an exothermic process) into a saturated or subcooled cooling liquid with high temperature and high pressure. The hot water assembly absorbs the heat released during the refrigerant's condensation in the water, raising the water's temperature. The cooling liquid is throttled and expanded through the expansion valve, becoming a low-temperature, low-pressure cooling liquid. The liquid refrigerant flows into the...

When applying phase voltage (230V AC) to the "ON" terminal, the valve will maintain its initial position of C-B, meaning that the fluid flow will occur from position C to B. When applying phase voltage (230V AC) to the "OFF" terminal, the valve will switch to position C-A, indicating that the fluid flow will occur from C to A. 8.1.6. CONTROL OF THE AFRISO THREE-WAY VALVE According to the diagram below, C is the input terminal, and the output terminals are A and B. When phase voltage (230V AC) appears at the "L" terminal, the valve maintains its initial position of C-B, meaning that the fluid flow occurs from C to B. When applying phase voltage (230V) to the "L1" terminal, the valve switches to position C-A, indicating that the fluid flow will occur from C to A. When phase voltage (230V AC) is disconnected from the L1 terminal, the valve will return to the C-B position.
  • Page 23 8.2. PREPARATION OF THE SYSTEM FOR STARTUP The initial startup and heating phase must be carried out by a qualified and authorized specialist, such as an Authorized Service Partner. Before the system is started for the first time, it should be filled with treated heating water (according to requirements). The following points should be checked before starting up: Before commencing work, the power supply to the heat pump should be disconnected at the circuit breaker. All hydraulic connections must be installed and leak-free. All valves in the heating circuit must be open. Partially closed valves could adversely affect the proper flow of heating water. All settings of the heat pump controller should be adjusted to the heating installation as per the instructions. The heating water circuit and buffer tank must be fully filled and purged of air. Purging of the heating installation - ensure that all heating circuits are open, purge the system at the highest point, and if needed, top up the water (maintain minimal static pressure). Check the insulation condition and correctness of electrical connections. It's important that they are properly protected and routed to prevent contact with liquid during filling and system operation. After completing the heating process, the set temperature value and actual temperature should show approximate values. If the water in the buffer tank is being heated, there will be a change in the tank's volume. 9. USAGE The installer should inform the user about the functions of the heat pump and provide necessary information for its safe usage. Before starting operation, it is important to read and understand this manual thoroughly, as well as the instructions of other applied devices, and adhere to the guidelines provided. The use of the heat pump should not be entrusted to children or individuals with limited physical, sensory, or intellectual abilities, or to individuals without the required experience and knowledge, unless they are supervised or instructed on how to use the device by a person responsible for their safety. The device should be stored out of the reach of children. ATTENTION Before starting to use the heat pump, it is necessary to inspect the overall technical condition of the unit. Please check if: All pipe connections are tight and not leaking.

  • Page 24: Kinspection And Maintenance

    10. INSPECTION AND MAINTENANCE External parts can be cleaned using a damp cloth and commonly available cleaning agents. Do not use any caustic cleaners or thinners to clean the device. In hospitals and other public utility buildings, adhere to the applicable regulations regarding cleaning and disinfection. If there is a risk of freezing during the shutdown of the heat pump, it is also important to consider that the risk of freezing extends not only to the water in the buffer tank but also to the water in all pipes leading to the radiators. Therefore, it is recommended to drain all fittings and pipes supplying water in the heating circuits. 10.1. MAINTENANCE During the inspection of control and protective devices, adjustments to the setpoint should not be made without justification. Pay special attention to whether various operational parameters of the system are within normal range during operation. Regularly check if the terminals of the electrical wiring are loose; if they are, tighten the terminal screws. Regularly inspect the condition of electrical components and promptly replace any damaged elements. After prolonged operation, calcium oxide or other minerals may deposit on the surface of the copper tubing in the heat exchanger. Deposits on the heat exchange surface will affect the efficiency of heat exchange and lead to increased energy consumption and higher refrigerant pressure. As the pressure drops, the amount of hot water to the unit decreases. The heat exchanger can be cleaned with organic acids such as formic acid, citric acid, and acetic acid. Dust from the fins of the evaporator should be blown off regularly (usually once a month) using compressed air with a pressure greater than 0.6 MPa, brushed with a specially designed metal comb, or flushed with pressurized water. If there is excessive dirt, use a brush with a strong detergent to clean it. After a longer period of inactivity, when starting the device, perform the following preparatory actions: thoroughly inspect and clean the device, clean the water installation, check the water pump, and tighten all pipe connections. Use original manufacturer's parts for repairs, and avoid using similar parts from other companies. 10.2. LEAK DETECTION AND PRESSURE TESTING During leak detection and pressure testing, never fill the cooling system with oxygen, acetylene, or other flammable and toxic gases. Only compressed air, nitrogen, or refrigerants should be used for such tests. 10.3. DISMANTLING THE COMPRESSOR Perform the following steps: Turn off the electrical power at the main device switch.

  • Page 45 16.4. DESCRIPTION OF INTELLIGENT NETWORK FUNCTION Signal Selection Using Two Inputs: FUNCTION DESCRIPTION The same logic is common for both states: the heat pump can operate in both room heating, underfloor heating, and cooling mode, as well as in domestic hot water heating mode. The heat pump will be actively engaged in the domestic hot water heating mode. If the heat pump is in room heating mode, the device will be forced to switch to heating + domestic hot water (DHW) mode, where priority is given to the current domestic hot water (DHW) mode. The heat pump and electric water heating in the DHW tank are turned on, and the compressor operates at a high frequency. When the DHW tank temperature >60°C, the compressor stops working, but the electric water heating in the DHW tank remains on. Then, when the DHW tank temperature >70°C, the electric water heating in the DHW tank will be turned off, and the heat pump switches to room heating mode. When the inlet water temperature >60°C, the compressor and additional electric heating will be turned off. If the heat pump is in underfloor heating mode, the device will be forced to switch to underfloor heating + domestic hot water (DHW) mode. In this mode, priority is given to the domestic hot water (DHW) mode in the DHW tank. The heat pump and electric water heating in the DHW tank are turned on, and the compressor operates at a high frequency. When the DHW tank temperature >60°C, the compressor stops working, but the electric water heating in the DHW tank remains on. When the DHW tank temperature >70°C, the electric water heating in the DHW tank will be turned off, and then it switches to room heating mode. When the buffer water temperature exceeds 60°C, the compressor and additional electric heating for the buffer will be turned off. If the heat pump is in cooling mode, the device will be forced to switch to cooling + domestic hot water (DHW) mode. In this mode, priority is given to the domestic hot water (DHW) mode in the DHW tank. The compressor operates at a high frequency, and electric water heating in the DHW tank is turned on. When the DHW tank temperature >60°C, the compressor stops working, but electric water heating in the DHW tank continues to operate. When the DHW tank temperature >70°C, the electric water heating in the DHW tank is turned off. When the water temperature at the heat pump outlet drops below 10°C, it switches to cooling mode. When the water temperature...
