## How to Add Freon to a Water Dispenser
Freon is a refrigerant used in many water dispensers to cool the water. Over time, the freon can leak out of the system, causing the water to become warm. If you notice that your water dispenser is not cooling the water properly, it may be necessary to add freon to the system.
### Safety Precautions
Before you begin, it is important to take the following safety precautions:
Wear gloves and safety glasses. Freon is a hazardous chemical that can cause skin and eye irritation.
Work in a well-ventilated area. Freon is a gas that can be harmful if inhaled.
Do not smoke or use open flames near the water dispenser. Freon is a flammable gas that can cause an explosion if it comes into contact with an open flame.
### Tools and Materials
You will need the following tools and materials to add freon to a water dispenser:
Freon refrigerant
Freon charging hose
Freon gauge
Screwdriver
Allen wrench
### Instructions
1. Locate the freon charging port. The freon charging port is usually located on the back or bottom of the water dispenser. It is a small, brass fitting with a Schrader valve.
2. Connect the freon charging hose to the charging port. The freon charging hose is a flexible hose with a male Schrader valve on one end and a female Schrader valve on the other end. Screw the male Schrader valve onto the charging port and then screw the female Schrader valve onto the freon refrigerant can.
3. Open the freon valve. The freon valve is located on the freon refrigerant can. Turn the valve counterclockwise to open it.
4. Slowly open the Schrader valve on the charging hose. The Schrader valve is located on the freon charging hose. Turn the valve counterclockwise to open it.
5. Monitor the freon gauge. The freon gauge is located on the freon charging hose. It will measure the pressure of the freon in the system. The pressure should be between 75 and 100 psi.
6. Add freon to the system. Slowly open the freon valve on the refrigerant can and allow the freon to flow into the system. Watch the freon gauge and stop adding freon when the pressure reaches 75 to 100 psi.
7. Close the freon valves. Once the pressure reaches 75 to 100 psi, close the freon valve on the refrigerant can and then close the Schrader valve on the charging hose.
8. Disconnect the freon charging hose. Unscrew the female Schrader valve from the refrigerant can and then unscrew the male Schrader valve from the charging port.
### Tips
If you are not comfortable adding freon to a water dispenser yourself, you can call a qualified technician to do it for you.
Freon is a hazardous chemical, so it is important to dispose of it properly. Do not pour freon down the drain or into the trash. Instead, contact your local waste management authority for instructions on how to dispose of freon safely.
### Troubleshooting
If you are having trouble adding freon to a water dispenser, here are a few troubleshooting tips:
Make sure that the freon charging hose is connected properly. The male Schrader valve on the charging hose should be screwed onto the charging port on the water dispenser and the female Schrader valve should be screwed onto the freon refrigerant can.
Make sure that the freon valve on the refrigerant can is open. The freon valve should be turned counterclockwise to open it.
Make sure that the Schrader valve on the charging hose is open. The Schrader valve should be turned counterclockwise to open it.
If the freon gauge is not registering any pressure, there may be a leak in the system. Check all of the connections for leaks and tighten any loose fittings.
If you have followed all of these tips and you are still having trouble adding freon to a water dispenser, you may need to call a qualified technician to diagnose and repair the problem.
