Disconnect from a network amplifier or other device that is connected to a sound system. Look on the speaker's rear panel two terminals: black and red. Please note that one of them is connected the conductor with the mark - remember what it is. Slide the levers and pull out the terminal wires.
To clean the speakers on the outside use a piece of lint-free cloth slightly moistened with a soap solution. Avoid getting water inside the speaker system. You can also use alcohol (not on all surfaces - some of it spoils), but in any case not acetone, gasoline, hydrogen peroxide, etc., Also can not be used instead of tissue paper - there are traces of its constituent fibers. After cleaning allow the surface to dry completely.
To open the column and clean it from the inside, first remove the grille. Sometimes she just pull, sometimes you need to Unscrew a few screws. Dust the inner surface of the grid with the help of the fan, do the same with the space located under the grille. The cleaner, even if it is a low-power, use with great caution - it may cause damage to the diffusers, dynamic head, protective cloth. If the diffusers are missing dust caps (today is very rare), blow through the gaps between the magnets and armatures coils rubber bulb.
Now locate the screws that hold the column cover. They can be front, under the bars and back. Remove them, remove the cover, preventing damage to conductors, blow out the speaker system with a fan inside, then close. To avoid getting dust into the lungs, do not lean over the treatment site, or use a respirator.
Assemble the loudspeaker in reverse order, then pull the terminals and connect them to the wires in the correct polarity. Release the terminals and they are fixed. Check the operation of the column.
Do not expose the audio system with a one-column or no column, as well as short circuits.
Advice 2 : How to clean limescale from the gas column
In those apartments where there is no Central supply of hot water without a geyser is indispensable. Gas geyser can save consumers from many problems in life. However, in order to function uninterrupted column, you should periodically clean it from scale.
You will need
- - rubber bulb;
- a syringe;
- - vinegar;
- vacuum cleaner.
Learn that, according to the experts, to clean the gas column must be at least once a year. Also to judge the necessity of cleaning a column, you can by the fact that she periodically boils and the stream of water coming from the pipe was much thinner. Indeed, in clean, at first glance, the water there are many different elements that contribute to the appearance of scale.
To clean the column from the resulting scale, it is necessary to disassemble the unit. First, untwist the pipe for the water outlet and inlet, then remove your column from its hinges and turn it upside down. Take a common rubber bulb or syringe and pour inside about half a liter of vinegar. After that, the column needs to stand for several hours.
Install the unit in place, but connect only the pipes through which water is supplied. Under the column install any capacity, for example, a large bowl. Turn on the water, which will wash away all the scum and impurities from the column. After from the column will flow cleaner water, connect all the other pipes.
It happens that the blockage is not in the column, and a gas burner. If there is too much soot, then be sure to clean the burner, otherwise the soot can clog the radiator. Turn off the gas, remove the cover on the column and using a vacuum, collect all the accumulated dirt and grime. Then make sure the burner lights up and does not require any additional purification.
You may not want to risk it and cleaned the blade, alone, afraid to ruin the Assembly. In this case, call the house of the master of professional gas services, housing Department or from a private firm. You can carefully observe his actions and remember their order to next time to try to clean it all yourself.
Advice 3 : How to flush a radiator of the gas column
The reason for the contamination of the radiator gas column is the formation of scale. As a result, the hot water valve decreases the pressure and reduces its temperature. Flush the radiator, using the means at hand.
You will need
- - garden sprayer;
- - hose PVC;
- two of the clamp;
- the descaling agent (for example, "Silit");
Turn off the gas. Close the valve on the incoming water pipe. Unscrew it so that the water remained closed, and the entrance to the column was loose. Better to do it together. One person unscrews the valve, and the second substitutes for the entrance of the column bucket, as the pipe water is going to come.
Flush the radiator the gas column in this way. Plug the spout of the faucet in the kitchen or in the bathroom stopper and turn the cold water tap. The water goes through the column in the opposite direction, washing out the radiator.
Drain the water into the bucket. Wait for it to go from column without mechanical impurities particle, and then proceed to descale the radiator.
Take a garden sprayer and Unscrew the cap on it. Cut from the cap tip with side holes. Slip into the resulting hole in the PCV hose and clamp it with the clamp.
Connect the other end of the hose to the pipe that is within the column. Secure with clamp. Pour into the sprayer container of water and descaling agent in the amount indicated in the instructions with the tool.
Screw the cap to the container. Close the hot water tap. Upload in the column about a third of the capacity of the sprayer. The rest of the money pumped approximately five receptions at intervals of a few minutes. Release the pressure in the pipe prior to each injection, opening the hot water tap.
The scum is removed when the hiss from the action of chemical substances in the coil of the radiator will stop. Connect the speaker to the water. Open the spigot and drain the water until until it is clean.
In order to prevent the formation of scale in the radiator heater manufacturers recommend to get the water the right temperature, without mixing hot and cold water with a mixer, and setting the desired temperature using the selector. If it is missing, in this case, after turning off the speakers drain the hot water from the radiator by opening the valve.
To the gas column during operation was not formed and the soot, once in two months, remove the veneer of the column and a thin brush to thoroughly clean the inside from dust.
