NOTES: 1 The above curve data are fitted based on the test parameters of Gree Laboratory(The test conditions are: initial water temperature: 10℃, power supply: 230V ~ 50Hz; in a new unit with clean heat exchangers). So there will be about 5% tolerance and the curves are for reference only. 2 When the electrical heater and heat pump are together started to heating the heating time of GRS-2.3Pd/TD270ANpH-K and GRS-2.3Pd/TD200ANpH-K will be decreased. On the other hand, COP will decrease and power consumption will increase. 6.

Air Source Heat Pump Water Heater 7. INSTALLATION 7.1 Unit Installation Diagram Fig.7.1-1 Unit Installation Diagram WARNING! To ensure water safety, Insulation plastic pipes such as PPR pipes are recommended to be used. The PPR pipe length at the water inlet and outlet is determined as per the formula: L≥70×R2, wherein L indicate the pipe length, and R indicates the inner diameter of the pipe (unit: cm). The pipes should be insulated properly. No metal pipe is allowed. 7.2 Installtion Dimension 7.3 Installation Requirements (1) Ensure that the sound and airflow of the unit will not affect people, animals, or plants, etc. (2) Ensure that the unit has good ventilation. If a canopy is installed to protect the unit, it should be noted that heat dissipation and heat absorption shouldn’t be affected. (3) The unit should be installed in a place with a solid foundation and make sure that the unit is installed upright. The impact of strong wind, typhoon and earthquake or other natural disasters should be fully considered, and the installation should be reinforced. Unit: mm 5
(4) Ensure the reliable connection of the drain pipe of the unit and lead the drain pipe to a proper place for drainage. (5) The unit must be installed in a place with rain and sun shading devices where it can be sheltered from rain. (6) The unit and water system piping and valves should be installed as far as possible in the ambient temperature above 0℃, and preferably installed near the main hot water point. (7) In order to avoid inconvenience or property damage to user due to water leakage caused by improper connection of water pipe or normal water release of safety valve, it is forbidden to install the unit in a place without good drainage. (8) The unit shall be located upright. The installation ground must be flat and spacious, and the foundation shall be solid enough to bear four times of the weight of the unit after the unit being filled with water. It is strictly forbidden to hang the unit or hang it on an external wall. When installing the unit, it’s necessary to use fixing belt to protect the unit. If the unit is installed in areas with strong winds, typhoons, or earthquakes, in addition to using fixing belt for installation, additional reinforcement measures must be taken to prevent the unit from tipping over under external forces, thus causing unnecessary unit damage or personal injury. The fixing belt of the unit only serves as an auxiliary fixation and cannot bear the weight of water tank. (9) The water quality for the air source water heater should comply with the local sanitation standard for the domestic drinking water and refer to the following water quality requirements. Table 7.3-1 Water Quality Requirements pH (25℃) 6.8~8.0 Turbidity (scattering turbidity unit)/NTU <1 Chloride/(mg/L) <50 Iron/(mg/L) <0.3 Sulfate/(mg/L) <50 Silica (SiO2)/(mg/L) <30 Total hardness (calculated in CaCO3)/(mg/L) <70 Nitrate (calculated in N)/(mg/L) <10 Conductivity (25℃)/(μs/cm) <300 Ammonia nitrogen (calculated in N)/(mg/L) <1.0 Total alkalinity (calculated in CaCO3)/(mg/L) <50 Sulfide/(mg/L) Shall not to be 7.4 Wiring The appliance shall be installed in accordance with national wiring regulations, and installation of the unit must be done by qualified personnel. The power supply must comply with the specifications on the nameplate. The carrying capacity of the power supply, wires and sockets should be confirmed before installation. The fixed circuit must be equipped with a residual current device (RCD) and a circuit breaker with sufficient capacity to ensure that all poles are disconnected from the power supply when necessary. The action time of the residual current device (RCD) should be less than 0.1s. The unit must be grounded reliably. The grounding wire should connect with special device of buildings. The unit circuit must be at least 1.5m away from any inflammable surface. Separate fixed device for power supply must be used, and its structure shall match the power supply of water heater, and comply with relevant national and local standards. Do not use socket converters, cable extension cords or wiring boards to accommodate the power cord of water heater, no switch to other power cords to accommodate family power. Connect wires for the water heater separately and do not share the same circuit with other electrical appliances. Please see the electrical schematic diagram for exact details. If the power cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard. It is not allowed to reconnect the damaged power cord. Air Source Heat Pump Water Heater detected WARNING! 6
