The installation steps of an electric water heater are as follows:
Determine the height of the location of the installation. The water heater should be installed in a position that has at least 250mm up and down, and at least 700mm on the front and both sides of the water heater for future maintenance. According to the installation size, drill 2 holes of 6mm and 90mm deep horizontally on a solid wall with a percussion drill, then insert the hook expansion bolt into the hole and tighten the hook, and make the hook up, and finally align the hanger above the electric water heater with the expansion bolt hook and hang it firmly.
Water pipe connections. All fittings are threaded with G1 2" (except for the blowdown) and are connected with one-way safety valves, inlet tees and outlet tees, and all connections should be gasketed.
Power connection. The standard three-hole power socket must be selected in line with the requirements of the national standard, and the grounding electrode of the power socket must be reliably grounded, and the grounding body shall not be replaced by tap water pipes, and the zero wire and ground wire in the socket shall not be connected together during installation. It is strictly forbidden to be charged on the ground wire, otherwise an electric shock accident will occur.
Choose the size of the wire. The power of the storage electric water heater is relatively large, and the choice of wires should use a large square copper core wire as the power supply line, and accurately connect the live wire, the neutral wire and the ground wire, and it is best to use a special plug for the storage electric water heater.
Check after installation. After the installation of the water heater, the installation work should be checked, and special attention should be paid to: the pipeline connection and direction should be reasonable, and there should be no water leakage at each connection; The electrical configuration should be safe and correct, and the power plug of the water heater should be closely matched with the socket; The mechanical connection should be strong and reliable; The use function should be well realized, and the control parts should operate normally.
Before installation, check that the wall on which the electric water heater is installed is indeed strong and can withstand 4 times the weight of the electric water heater when it is filled with water. Expansion bolts cannot fit in brick joints. After installing the storage type electric water heater, it is necessary to use electricity and water to try the heating effect, and if there is a leakage spot, repair it immediately.
In addition, the pressure relief valve must be installed, and the pressure relief valve is installed at the water inlet, mainly to ensure that the pressure is discharged in time when the water pressure is too large during the heating process, to ensure the safety of use, to prevent the water from flowing backwards when the water is stopped, to ensure that the machine must be in a state of full water, and to avoid dry boiling. When the electric water heater is installed, it must be filled with water for the first time before it can be turned on for heating, so as to avoid dry boiling.
