4 Matters needing attention for installation·Components introduction „ Matters needing attention for installation z The electric water heater should be installed indoors where the ambient temperature is above 0℃; pipelines should be arranged together. It is not suitable for the hot water outlets far away from the water terminals. If the distance is over 8m, heat preservation treatment should be carried out on the pipeline to reduce heat loss. z The electric water heater should be installed in places where it is easy for use and maintain and there are buried pipes. In case of water leakage in the water tank or water pipes, no damage will be caused to the nearby or lower story facilities. Besides, don't install the water heater in places where water sprays directly and it is easily frozen. z Due to its high power, before installation of the water heater, carefully inspect whether the electric instruments, the wire diameter of power supply and fuse meet with the requirements of the rated current and voltage of the water heater. z Intake and outflow pipes must not be connected inversely (hot on the left and cold on the right). z To ensure safety, air switch which measures up to the standard of the state should be used in the water heater, and be grounded reliably. As the required current is very high, the power supply of the incoming line should be connected directly to the air switch. Do not use the power plug. z Check whether the live wire and the zero line are connected inversely with an electroprobe. Power-on the water heater for heating until it is confirmed that the water tanks are fully filled with water, there is no water leakage in the various joints and the power supply meets the requirements. z Safety warning: in order to prevent the occurrence of accidents, accessories such as hosepipes and shower nozzles provided by our company must be installed and must not be replaced or substituted; if the pipe fittings are damaged, inform our company's repair & maintenance department to repair them and replace them with accessories provided by our company.
