As the outdoor unit may be exposed to sub-zero temperatures, care must be taken to prevent freezing of the system. All internal hydronic parts are insulated to reduce heat loss. Insulation must also be added to the field piping. ● The software contains special functions using the heat pump to protect the entire system against freezing. When the temperature of the water flow in the system drops to a certain value, the unit will heat the water, either using the heat pump, the electric heating tap, or the backup heater.

- Page 78 FAILURE CAUSE MALFUNCTION OR ERROR CODE PROTECTION AND CORRECTIVE ACTION The condenser refrigerant The outside ambient temperature is too high(higher than 30°C, the outlet temperature is too high in unit still operate heat mode. close the heat mode when the ambient heating mode for more than 10 temperature is higher than 30°C.
- Page 79 FAILURE CAUSE MALFUNCTION OR ERROR CODE PROTECTION AND CORRECTIVE ACTION 1. The same reason to P1. 2. System is lack of refrigerant volume. Charge the refrigerant in right volume. High discharge temperature protection. 3. TW_out temp sensor is loosen Reconnect it. 4.
- Page 80 FAILURE CAUSE MALFUNCTION OR ERROR CODE PROTECTION AND CORRECTIVE ACTION 1. Heat exchanger cover is not removed. Remove it. 2. Heat exchanger is dirty or something is block on the surface. High temperature protection Clean the heat exchanger or remove the obstruction. of refrigerant outlet temp of condenser.

Page 82: Replacement Of Safety Valve (Only For 12~16Kw Units)
REPLACEMENT OF SAFETY VALVE (Only for 12~16kW units) Visual inspection is needed after that period, maintenance people should check the appearance of the valve body and the operating environment. If the valve body is not obvious corrosion, cracks, dirt, damage, then the valve can be used continually. Otherwise, please contact your supplier for spare part. - Page 83 7) Ventilated area Ensure that the area is in the open or it is adequately ventilated before breaking into the system or conducting any hot work. A degree of ventilation shall continue during the period that the work is carried out. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the atmosphere.
- Page 84 14) Leak detection methods The following leak detection methods are deemed acceptable for systems containing flammable refrigerants. Electronic leak detectors shall be used to detect flammable refrigerants, but the sensitivity may not be adequate, or may need re-calibration. (-Detection equipment shall be calibrated in a refrigerant-free area.) Ensure that the detector is not a potential source of ignition and is suitable for the refrigerant. Leak detection equipment shall be set at a percentage of the LFL of the refrigerant and shall be calibrated to the refrigerant employed and the appropriate percentage of gas (25% maximum) is confirmed.
- Page 85 18) Labelling Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated and signed. Ensure that there are labels on the equipment stating the equipment contains flammable refrigerant. 19) Recovery When removing refrigerant from a system, either for service or decommissioning, it is recommended good practice that all refrigerants are removed safely.
