To delete electric solenoid valve water from the system, open the side of the switch that controls the motor circuit. Remove the water valve cables out of motor circuit. If these wires are soldered to the tape, you have to unsolder or reduce them. Most slip connections.
Before disconnecting the valve supply of water from water supply system, shut off the water supply Is done with the help of a manually operated valve. If the spare valve is available, temporarily connect to the water supply system without it. Water consumption is controlled manual shutoff valve.
Some pressure-operated water valves difficult to remove from the system because we are connected to the high-pressure side of the condensing unit. Pressure tube for these valves are usually associated with compressor cylinder head. However, some manufacturers connect this tube in the liquid line. Sometimes this tube has a manual shutoff valve. If so, the simple removal of the valve.
If the tube is connected to the cylinder head compressor proposed the following procedure:
Install the sensor manifold.
Turn the suction valve.
Compressor start until the pressure in the crankcase reaches 0 psi.
Note; Be very careful pumping oil, which sometimes occur to 0 psi achieved.
Heat the water valve line and the water valve bellows carefully heat lamp. Do this for three or four minutes imti! both are quite warm to the touch. This operation will move the liquid refrigerant which is condensed into this tube and valve back into the condensing unit. Then, only a small number of high-pressure steam will remain in this tube.
Turn discharge service valve.
This bypasses the high pressure in the reservoir and the water valve the refrigerant line on the low side. Open both combs.
Clean the joints can be opened.
Disconnect the pressure pipe from the water valve. Put on your glasses!
Pressure sensor connector tube holes at once.
Gently heat the water valve again. Often, the amount of liquid refrigerant oil becomes associated with the bellows of the chamber. It produces with the explosive force of a few minutes after the valve is open to atmosphere. Heating will drive it out. Note: Be very careful not to point refrigerant holes toward anyone. There is a danger of the refrigerant. It is best to wrap the refrigerant holes with several layers of heavy towel. Towels will absorb any of the refrigerant being thrown from the mechanism.
Disconnection of water supply.
Disconnect the valve water from the mains. Replace it with a new valve or water connection lines directly. Now the water valve is ready to be disassembled and restored.
Some water valves permit removing the valve body without breaking the refrigerant connections. To disable these valves, shut-off water. Disconnect the valve body of water lines and furs body. Thermostatic valves water or motorized water valves are easily removed. Only the electrical connections must be destroyed and water circuit is closed...
