Advice 1: How to restore membrane

The membrane (Gore-Tex) has a porous structure. Used for making outdoor clothing and sports equipment. Not blown by the wind and not get wet. Gore-Tex need to recover after operation in extreme conditions: long exposure to the sun, constant humidity and rain, the abrasion of the rough surface. If your products are not lost density, you observe the operating instructions, then restore the membrane .
How to restore membrane
You will need
  • Stain remover and spray for membrane fabrics.
Instruction
1
Working with Gore-tex should be carefully because the tissue structure loses its properties in case of improper application of cleaning products. To restore you only need a clean cloth, so that dirt is not clogged in the pores of the membrane. Use the tools bought in specialized stores, sports and tourist equipment.
2
Clean the tissue from external contaminants with a soft brush. If the clothes are heavily soiled, you need to add bleach in the dispenser for powder. If you have purchased a spray stain remover spray it on stains before you load clothes. Put the clothes in the washing machine, pour in the dispenser for powder in the proportions indicated on the back of the bottle. Set the mode to "impregnation". If this mode is not available, make the temperature not more than 30-35 degrees and spin up to 600 rpm. If such functions in your washing machine is no need to wash by hand to avoid damaging the fabric.
3
After washing, remove the clothes and leave it to drain and dry, pre-straightened to avoid kinks in the fabric.
4
After complete drying of the fabric, evenly spray on her impregnation. Depending on manufacturer you may need to apply several layers. This will preserve the main properties of Gore-Tex material. This step is the most important in the restoration, so carefully apply where the tissue has become less elastic or have lost the texture.
Note
There are a number of potent chemicals in the composition of the impregnation and stain removers, so you should carefully read the instructions to avoid allergic reactions.
Useful advice
Try not to crumple the product of membrane fabric, not to hurt its structure. Even if You have no opportunity to clear and wash the product, but it is necessary to exploit it, treat it water-repellent. This will prevent tissue destruction and loss of its properties. Then take the first wash and treat the product.

Advice 2: How to replace the diaphragm in the accumulator

An integral removable part of the accumulators in the Autonomous water stations (SAV) are membrane separating the pressure in a water and air chamber. Because membranes undergo temperature extremes, as well as a significant strength of tension and compression, it is necessary to periodically replace them.
How to replace the diaphragm in the accumulator
Instruction
1
Disconnect the accumulator from the system by unscrewing the nut and removing the hose. Bleed the gas pressure in the air chamber, after the air through the nipple. Unscrewing the bolts, remove the flange of the membrane, located in the region of the tube to presedintie.
2
Holder membrane by unscrewing the nut located in the upper part of the housing of the accumulator. Remove the membrane through the hole in the bottom of the hull. Remove inner housing surface traces of dirt and corrosion, clean with water and dry to make the installation of the new membrane.
3
Insert the membrane holder into the hole located in its upper part. Screwing the bolt into the holder and inserting the membrane into the housing, enter the holder into the hole located in the bottom of the case. Nut lock holder and refit the flange to the membrane on its body. After the installation of preliminary air pressure, check the accumulator for leaks and connect it to the system.
4
Check the diaphragm and its flange on the integrity, faced with a situation where SAV is running, but not supplying water. Bonding of the membrane at the break is only a temporary measure, are not able to significantly increase its service life. Another cause of a failure, the CAB may be a loose connection between the flange fitting and the housing of the accumulator.If the station was operated without water, the membrane is, most likely, were pressed by pressure to the flange and has become an obstacle to the flow of water in the suction line of SAV. In this case, you must remove and spread the membrane, and then set it in place, after checking for integrity.
Note
Do not use for protection against corrosion the inside of the housing of the accumulator oily substance.
Useful advice
If you are not able to replace the membrane, wash it with a solution of baking soda, to remove plaque additives. Spend such a cleaning 1-2 times per year, depending on the intensity of use of SAV and the amount of additives in the water.

Advice 3: How to repair speaker

If the speaker is out of order, this does not mean that we need to throw it away and buy a new one instead. You can try to fix it. There are several main causes of breakdowns of the speakers and some basic methods of their repair.
How to repair speaker
Instruction
1
Identify the cause of the failure of the speakerand to be able to restore it. The main causes of failure can be a blockage, a break of the diffuser, a breakthrough of the membrane, the separation of the contacts of the coil from the cone speakerbut the failure of the magnet (lead magnet), combustion coil. In some cases you will be able to fix the dynamics of their own, in some of the best to take it to a service center for warranty repair (if possible) or buy a new one.
2
Pay attention to the sound of a speaker. If there are any noises, noises or hum, may be a cause of failure lies in faulty diffuser. Remove the mounting screws, remove speaker from housing speaker.
3
Remove it carefully so as not to damage the pins that go from it to the protective circuit with a frequency filter. To make it easier to restore the speaker, unsolder it from these contacts.
4
Inspect the diffuser for the presence of breaks, holes, etc. Also note on the membrane, but rather on its integrity. If breakthrough there is, take a piece of cloth of medium density. It is important that it was plastic. Take the glue viscous consistency (super-glue will not work). Seal a breakthrough.
5
Inspect the docking speakerand the coil. Take a cotton swab, dip it in alcohol and remove all dirt on the back speakerand because it can also have a negative impact on his work. Check the integrity of contacts coming from a cone speakerand to the coil.
6
If they are broken, solder them to the remains of the contacts and / or extend and secure again directly to the diffuser. To do this, use a thin sewing needle and fine thread. After flash contacts, glue them with glue viscous consistency.
7
Check for a speaker. Turn it on low volume, gradually increasing it. If upon reaching a certain volume, it stops playing, or starts to wheeze in a diffuser and the membrane, then, most likely, fell off the winding reel. Rewinding it yourself is very difficult because of the huge number of turns that have to wind manually. Think, perhaps, it makes sense in this situation to just buy a new speaker.
