Programmable constant temperature and humidity test box operation precautions
　　 A In order to avoid machine failure in the ASLI programmable constant temperature and humidity test chamber, please provide power within the rated voltage range.
A To prevent electric shock or malfunction and malfunction, do not turn on the power until the installation and wiring are completed.
　　 A This product is not explosion-proof. Please do not use a constant temperature and humidity machine in a bad environment with combustible or explosive gas.
　　 Please do not try to open the test box door when working in A instrument. Open it at high temperature may cause scalding to the operator. Opening at low temperature may cause frostbite to the staff, and may cause the evaporator to freeze and affect the cooling effect. If you have to open it, please do some protective work.
A It is forbidden to dismantle, process, reform, or repair the constant temperature and humidity machine without authorization, otherwise there is a danger of abnormal operation, electric shock or fire.
 　 A Periodically check the terminal screws and holders. Do not use them loosely.
　  A During the operation of the instrument, the power input terminal cover must be installed on the terminal board to prevent electric shock.
 　 A meter AI Si è” reminder: In operation, before modifying the settings, signal output, start, stop and other operations, should fully consider the safety, the wrong operation will cause damage to the working equipment or failure.
　  A Use a dry cloth to wipe the meter. Do not use alcohol, gasoline, or other organic solvents. Do not splash water on the meter. If the meter is immersed in water, stop using it immediately. Otherwise, there is a danger of electric leakage, electric shock, or fire.
     A The internal parts of the instrument have a certain life span. To use the instrument continuously and safely, perform regular maintenance and maintenance. When disposing of this product, dispose of it according to industrial waste.
　　 The ventilation holes of the A body must be kept clear to prevent malfunctions, abnormal movements, reduced life, and fire. Â
　　 A If the machine is damaged or deformed when it is unpacked, do not use it.
　   A. When installing the machine, be careful not to allow dust, threads, iron chips, or other objects to enter. Otherwise, incorrect operation or malfunction may occur.
　　 A wiring must be correct and must be grounded. Ungrounded may cause electric shock, malfunction, abnormal display, or measurement error.
 　  A. Before turning on the power, check whether the power supply is stable.

A storage tank water heater is water-heating container that uses a large tank to store hot water until it is needed. This type of water heater is typically powered heating steam or gas, and is used to provide hot water for a variety of uses, including showers, dishwashing, and laundry, or other hot water requests alike. The tank is typically insulated to help maintain the water temperature and reduce energy costs. Storage tank water heaters are a popular choice for many households because they are relatively inexpensive and can provide hot water for multiple uses.
Typical heat exchanger structure is heating spiral coil inside of a steel shell. Water will be heated while passing through inside the coil, and received the energy or heat from hot steam or gas.
The main disadvantage of a storage tank water heater is that they are less energy efficient than tankless water heaters. This is because they continuously heat and reheat the same water, which can waste energy. Additionally, storage tank water heaters require more space than tankless water heaters, as they are larger in size.
In that sense, recent years are seeing storage tank water heat exchanger giving way to other efficient products, such as Shell And Tube Heat Exchanger, Plate And Frame Heat Exchanger, and so on.
