Refueling air conditioners involved in service. But some owners would like to master this procedure on their own. First you need to get all the necessary tools.
Tools and equipment for refueling air conditioners
The following equipment is required for operation:
- refrigerant bottle;
- electronic scales for freon;
- pressure gauge with fittings and shut-off valve;
- vacuum pump for refueling air conditioners;
- screwdrivers;
- adjustable wrench;
- inspection mirror;
- puncture for a disposable balloon;
- valve adapter under the nipple;
- shut-off valve for refrigerant cylinder;
- cylinder for refueling;
- hoses for refueling air conditioners with union nuts;
- thermometer.
Cylinders for refueling air conditioners
When buying a cylinder for filling the air conditioner, special attention should be paid to the type of refrigerant.
It is indicated in the instructions. Cylinders for filling air conditioners contain from 10 kg of refrigerant and more. But for one refueling it is quite enough to purchase a small disposable bottle of 300 - 400 grams.
To use a disposable cylinder, you will have to buy a separate piercing for the cylinder. It is very inexpensive.
A shut-off valve is attached to refillable cylinders.
Air conditioning refueling pump
The vacuum pump for filling the air conditioner is used at the stage of preparing the piping to start the refrigerant. The pump cleans the system of residual freon, moisture and mechanical debris.
For working with domestic air conditioners, a vacuum pump with a capacity of up to 50 liters per minute will be quite enough. The weight of such a pump for refueling air conditioners is about 10 kilograms.
Pressure gauges for refueling air conditioners
It is most convenient to use a manometer for refueling the air conditioner built into the manometer manifold. Ready-made collectors of various companies are sold in many specialized centers. To save money, you can purchase a separate pressure gauge, and a manifold separately to it. Thus, the optimal options for work are selected.
Scales for refueling air conditioners
For refueling air conditioners, only electronic scales are used. They are very convenient to carry, as they are built into a small plastic case. The maximum load of the balance for refueling air conditioners is 100 kg. But more is not required.
Air conditioning hoses
To refuel a domestic and semi-industrial air conditioner, you need to purchase two hoses. They are made by special technology, as they must withstand high pressure. On both sides, the hoses end with external nuts. The standard length is 0.9 meters. Hoses for refueling air conditioners can be purchased complete with a manometric manifold or separately.
