Copper hydraulic joints are important parts in water heaters. Improper handling will bring certain harm to the personal safety and property of users. Knowing the proper use of wiring terminals in water heaters and taking relevant preventive measures is to avoid hidden dangers of accidents. occur.
1. Lay PVC hard plastic pipe, or lay it outdoors. It shall not be laid in places with high temperature and susceptible to mechanical damage. Feige hydraulic experts emphasized: "If the power cord or terminal block is damaged, in order to avoid danger, do not operate blindly. You must use the manufacturer's special power cord or the terminal block with quality certification, and it must be replaced by professional maintenance personnel.
2. The host is connected by a three-pole plug and a sheathed wire. When crimping the wire according to the NL and grounding symbols marked on the three-pole plug, it must be in one-to-one correspondence with the wires on the crimping terminal of the electric heater to prevent short-circuit accidents caused by crimping.
3. The connection of the hard plastic pipe must be firm and sealed. The Mingfu hard plastic pipe shall be protected by steel pipes in places that are prone to mechanical damage through the floor, and the protection height shall not be less than 0.5m.
4. The core of the wire should not be damaged when the insulation layer of the wire is cut. The wire connected to the electric heater must be tinned or treated as a crimped wire end.
5. After the hard plastic wire pipe is applied to the solar water heater bracket, a waterproof bend must be made, and a section of wiring from the waterproof bend to the junction box of the electric heater must be protected by a corrugated pipe.
6. The wires of the corresponding color should be crimped according to the NL and grounding symbols marked on the terminals of the electric heater.
