water Dispenser to power as a driving force, if leakage occurred fountains, bad insulation, are extremely dangerous. First of all, when consumers buy products to look for the brand and electrical safety certification through the Commission of China among the many brands, models dispenser products can be summed up in nothing more than hot, hot ice, three types of hot ice, ice and sub-semiconductor heat engine and compressor cooling water dispenser refrigeration of two drinking fountains. Decided to buy the types of drinking fountains, mainly from drinking water and cooling rate of the number to consider. On the cooling speed, in the same period of time under refrigeration, refrigeration compressor with water much faster than the semiconductor cooling water dispenser, water supply and more than the latter. Therefore, the refrigeration compressor suitable for drinking water fountains in a large number of occasions, such as group, institutions, conference rooms, office space, offices, bars, karaoke halls OK. The small number of units, hotel rooms and the general families, to buy semiconductor refrigeration enough drinking fountains.

Feature selection

Consider buying from the functional use of water dispenser, which is important. If you do not like to use cold water dispenser modulation, and day-to-day is used only for tea and instant coffee, buy a hot water dispenser on the can, both functional and economic, if more young people, together with the South is located in tropical areas, the summer of heavy utilization,且又like cold, and should be the purchase of hot and cold water dispenser. In addition, there are three warm with ice machine, can be choose.

Appearance

Spray dispenser surface should be smooth, uniform color, deep sound, there should be no cracks, scratches, defects such as foaming, the seams connecting symmetry.

Test water

After determining the appearance, the next step is after the water test, methods and steps are as follows:

First check the water dispenser cap, if there is no smart-seater that does not have the water system to prevent secondary pollution, such fountains should not buy. Into a solid block to smart, demolition should be smooth. Block and the Smart Guides to strong thread binding; if loose, can not be tightened on Block I. threaded column and clever combination of bad, for future use, guide column or break off the roots easily. Bottled water into the tank (usually water 2-3 times), the do not press the tap, tap water should not be the phenomenon (the normal water seal); observation bucket water level, if water levels are falling sharply, and that there is water leakage machine (rubber to take over first extrusion to produce leakage), not to buy; press the tap by hand (1.5-2 seconds after cooling, after heating of about 2-2.5 seconds), tap water should be out of the water flow on the normal function of drinking water. If there is no water or water slowly, and that water blockage or abnormality of this machine.

Check the electrical performance

Water, access to power, rather than pressing the refrigeration, heating power switch several times, switching contacts should be good, then the corresponding indicator light shows that the normal drinking fountains circuit. Press the refrigeration switch, with his hands near the back air, and exhaust flu did not hear any noise in the weak noise, fan is operating normally. Electricity after two hours, press the cooling water, cold water outflow due. Such as semiconductor refrigeration, to enable the water temperature 5-15 ℃, refrigeration compressor to enable the water temperature 4-12 ℃. Press the heating switch, heating 15-20 seconds, the water temperature should reach 92-96 ℃. During the heating indicator light will automatically Qiliang, extinguished. Drinking fountains with disinfectant function, press the disinfect button and the time after disinfection should be able to automatically turn off power indicator goes out. Check the power cord insulation layer should be no damage, the use of sufficient capacity and a dedicated power cord plug.

After-sales service

May request in advance to buy the warranty card, read carefully, if there is no warranty card, it is best not to buy. In addition, it is best to buy local manufacturers warranty fountains sector. Some manufacturers (vendors) also provides cleaning and disinfection services, consumers should be considered.
