Installation Attention during installation Installation During heating, water may drip from the drain hose of the pressure relief hole due to expansion and the hole must be left open to the atmosphere. Check safety valve once a month as follows: move the small handle of the safety valve, if there is water flowing out, the safety valve is normal; if there is no water flow, please contact local after-sales service station. The pressure relief hole is to be operated regularly to remove lime deposits and to verify that it is not blocked. Attention during installation Please fasten the drain hose to the pressure relief hole of the safety valve by twisting (see to Figure 4). Connect the other end of drain hose to the sewer to avoid polluting the room by splashing. When the power is switched on, and the water heater starts operating, there may be some water discharged from the pressure relief hole of the safety valve. It is due to the water expansion under heating, and is a normal phenomenon. The pressure relief pipe shall communicate with the air directly. Do not block it. The drain hose connecting to the safety valve shall be kept downward sloping in installation and in a frost-free environment. Be sure to check and confirm that the tank is filled with water, there is no leakage at each joint and the power supply complies with the stipulation before switching on the power. Connect to drain hose (Figure 4) Safety precautions: 1. Do not confuse the water inlet and outlet pipes. The water bearing the water heater shall be strong enough to endure a weight twice as much as that of a water heater filled with water. Do not secure it by means of adhesive or similar products because the fixation by such methods is unreliable. 2. To avoid danger caused by accidental resetting of the heating breaker, the power for the heat cannot be supplied by timer and other external switch devices or connected to circuit with frequent switching for facility use. 3. If any part is damaged, please contact the local maintenance agent and have it replaced with our spare parts. 4. Tap water inlet pressure shall be no less than 0.05MPa and the maximum pressure shall not exceed 0.75MPa. 68 Safety Precautions Safety Precautions 230V 50Hz Check if the ammeter and the diameter of the wires are in accordance with the rated current of the water heater.
