Description

Vacuum-rated to 20 microns, our Valve Core  Removal Tools (VCRTs) are essential tools in every HVACR technician’s tool kit. Removing a valve core helps speed up charging & recovery operations. Valve cores are also a common leak point of a system.

The integrated sight glass allows you to positively verify you have captured and removed the valve core before fully removing the captured assembly from the VCRT body – saving you time, headaches, and refrigerant loss. The comfort spinner on the end of the capture rod assembly makes it simple to apply pressure while still turning the knob to remove or install the valve core.

Rated for high-pressure refrigerants including R410a.
A2L is compliant as the base materials don’t degrade from exposure to related gases and lubricants.

How to Use

Valve Core Removal

1. HAND-TIGHTEN the system fitting to the system access port of the unit and pull the capture rod out from the VCRT body.

2. Push in the capture rod and slowly rotate the knob while applying pressure to the comfort spinner until you feel the capture rod fully engage the valve core.

3. Maintain pressure on the comfort spinner, rotate the knob counterclockwise until the valve core is completely loose

   • WARNING : Ensure the system fitting doesn’t turn. If loosened, there is a risk of refrigerant leaking out.

   • NOTE : Once the valve core is loose, the system refrigerate pressure will cause the capture rod assembly to push outward from the body.

4. Slowly pull the capture rod out to extract the valve core through the body until it is removed. If extracting successfully, you will be able to see the valve core through the sight glass as you pull out the capture rod.

5. Close the inline valve.

6. Unscrew the rod fitting counterclockwise to remove it from the tool. Hang it onto the system to keep it protected & off the ground.

Service & Install New Valve Core

1. The inline port now has maximum flow. If needed, connect a service hose and open the line valve to perform the service. Use the side port to attach vacuum or pressure gauges.

   • NOTE : If connecting a hose to the side port,  ensure the valve core is removed prior to attaching. Do not evacuate through hoses with low-loss fittings. Use the shortest vacuum hoses with the largest diameter available.

2. Once completed, close the valve & remove any unneeded service hoses and gauges.

3. With a new valve core attached, carefully reinsert the rod into the body & thread the rod fitting onto the inline port clockwise until
   HAND-TIGHT.

4. Open the inline valve and gently push in the rod until you reach the system access port. Rotate clockwise until the new valve core is tightened and threaded in securely.

5. Pull out the capture rod and close the valve.

6. With a pressure gauge attached, confirm it’s at the required level & remove the gauge.

7. Slowly remove the VCRT from the system access port by hand loosening it counterclockwise and then check for leaks. If you notice leaks, retighten the VCRT, and tighten the valve core with the capture rod.

   • PRO TIP : To help maintain a vacuum-tight seal, a light coating of vacuum grease or vacuum pump oil may be applied to the system access port and the inline & side ports of the tool.

Class A2L/A2/A3 Refrigerant

Safety Notice

Systems using class A2L (mildly flammable), class A2 (flammable), or class A3 (highly flammable) refrigerants can be tested safely ONLY by qualified personnel explicitly trained in the use and handling of those refrigerants. This manual is in no way a replacement for proper training.

Swapping Out System Fittings

Continue below to replace the 1/4″ Fitting or switch to the 5/16″ option (Model RVC5) which is typically used for mini-split servicing

1. Remove and pull out the capture rod assembly from the VCRT body.
2. Hold the body tight and using an adjustable or 18mm wrench, twist the nut of the service port fitting counterclockwise to loosen and remove.
3. Ensure the o-ring is secure on the fitting and in good condition. Replace if it is scratched or damaged. Failure to use a good o-ring may result in leaking.
4. Using proper alignment, HAND-TIGHTEN  the new system fitting clockwise to the body, and use the wrench to lock it into place.

Maintenance

• Regularly inspect and maintain your VCRT to ensure its functionality & cleanliness. Store them in a safe and secure location, out of the reach of children.
• CLEANING : Clean the exterior with a damp cloth. Do not use detergents or solvents.
• NOTE : If you suspect a leak in the tool, perform an isolation test to be sure and contact us for repair options.
• Failure to follow these instructions could result in injury, damage to the unit, or death.
• Always exercise caution and follow proper safety procedures when working with this tool.
• ISOLATION TEST : You will need the following:
• (1) Vacuum Pump, (1) High-Accuracy Vaccum Gauge, (1) Vacuum Hose & (1) Empty Recovery Cylinder.
• NOTE : If testing a 5/16” VCRT, you will need a tank with 5/16” ports or an appropriate adapter.
• NOTE : All components (other than the test tool) must be known-good, clean, dry and have no leaks. This isolation test should not be rushed.
• Experience and a high-accuracy vacuum gauge will allow for shorter evaluation times.

1. Close the valves on a known-good and dry recovery cylinder.
2. Attach the VCRT to the vapor port of the cylinder.
3. Attach the vacuum gauge to the side port.
4. Attach the vacuum hose to the inline port of the VCRT. Connect the other end to the vacuum pump.
5. Open the vapor port valve of the cylinder.
6. To start the test, turn on the vacuum pump.
7. Allow the vacuum gauge to pull down to 200 microns.
8. Close the inline valve halfway on the VCRT. Allow the vacuum gauge to pull back down to 200 microns. Fully open the inline valve on the VCRT and wait 10-15 seconds. Close the valve halfway again and check that the vacuum pressure does not rise. If the vacuum pressure rises, repeat opening and partially  closing the valve until the pressure does not rise. Fully close the inline valve on the VCRT. Turn off the vacuum pump and remove the vacuum hose.
9. Allow the setup to rest for 15-20 minutes. The gauge should not rise beyond 500 microns. If so, the VCRT is properly holding a vacuum.
   • NOTE : When comparing a proper rise to a leak, a proper vacuum will have a slight rise that equalizes over time. This is opposed to a leaky tool that steadily rises back to the atmosphere.
