First hold the end of the glass tube near the insulating barrel with your hands, then slowly twist it. If it spins, crouch on the other end of the glass tube, which is the close end of the glass tube. ground and slowly hold it with both hands. Twist and push up while rotating. Be careful not to break the bottom end of the glass tube, that is, the small tip of the insulating tube at the end near the ground. twist and push up until the small tip can be lifted out of the space in the shelf. If you can lift it, pay attention to the small point and hold it with your hands. It rotates while pulling down, then you can remove it. a tube. Repeat the steps above during installation.
The solar water heater is a heating device that converts solar energy into thermal energy, heating water from low temperature to high temperature to meet the useilization of hot water by people in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters based on their structural shapes. Evacuated tube solar water heaters are mainly used, accounting for 95% of the domestic market share. Household evacuated tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into thermal energy mainly relies on vacuum heat collecting tubes which use the principle of hot water floating. and cold water flows to cause microcirculation in the water. Get the hot water you need.

1. When arranging pipes andvalve installation, you should first take a look at the gas interface and water inlet and outlet interface at the installation. directly place and install the cold water valve and hot water valves are generally hot on the left and cold on the right when installing, be careful not to close the main water inlet valve and the water inlet valve air intake to your house only in this way. can you avoid the phenomenon of “water flooding the golden mountain”.
2. Unpack the water heater packaging. Regardless of which channel you purchased the water heater from, you need to unpack it first to see if the accessories inside are complete. Of course, if you don't know much. about this, it is best to ask a professional Inspection staff, in addition, you can also rely on the manufacturer's accessories instructions. Generally, there is an expansion coil, a cosmoke screen, an elbow and a shower head. However, the configurations of different manufacturers may be different, so it is best to ask clearly.
3. Installation of the smoke evacuation pipe. This step consists of installing the smoke evacuation pipe. You should pay attention to it, otherwise it will pose a security threat for future use. Generally, the smoke extraction port is designed by the developer and the location is reserved. If there is none, then you must make an inclined opening yourself, high towards the inside and low towards the outside. In order to facilitate the adjustment of the water heater after hanging it on the wall, you must first install the flue pipe. You also need to pay attention to the metal material between the exhaust pipe and the wall, due to the temperature of the exhaust. The pipe is high when the water heater is used, and the plastic cover will be burned andwill even lead to other hidden dangers.
4. Installing the gas valve. This step requires connecting the air inlet hose to the gas meter. Be sure to close the main air inlet valve before installation. Generally speaking, house gas should be supplied to both the stove and the water heater, therefore a three-way valve should be connected to the gas outlet of the gas meter. Since the Angle valves are difficult to use, it is recommended to use ball valves. Particular attention should be paid to the installation of rubber seals when connecting pipes to prevent air leakage.
5. Preparing to drill the water heater before installing it on the wall. Measure the installation position of the water heater according to the position of the flue pipe and make a recording on the wall. drill to drill the hole and press the plastic expansion tube andthe screws. Install the gas water heater on the wall and connect the pipes. Hang the hot water device on the wall and seal the flue pipe with aluminum foil. Then connect the water inlet pipe, water outlet pipe and gas pipe. prevent air and water leaks.
6. Test and inspect. After installation, check whether it can be used normally. The way to check for air leaks is to apply soapy water to the connection.
