Question about Heating & Cooling
If you are not a service technician you probably won't have the tools you will need to accomplish the move. Here is what it takes, step bye step. 1. Pull the fuses or turn off the electrical breaker in the house. 2. Hook up a gauge manifold to the Condensing unit ports for the liquid and suction lines. 3. Hook up a Refrigerant recovery machine to the manifold. 4. Recover the refrigerant into recovery tanks down to a trace, no vacuum. 5. Disconnect the electrical whip and control wiring from the condenser. 6. Close off the service valves on the liquid and suction lines at the condenser. 7. Slowly unscrew the copper line connections to the condensing unit to relieve any pressure that may exist from Refrigerant boiling out of the oil in the compressor and quickly cap them. 8. Move the unit to your new, firm and level location. 9. Remove the old electrical disconnect and whip and move it to the condenser. 10. Buy a new line set of the proper length or extend the old one with Refrigeration copper and couplings preserving the condenser couplings. 11. Replace the liquid line drier and reconnect the copper lines to the condensing unit. Replace the "O" Rings if needed to insure a good seal. 12. Hook up a vacuum pump to your gauge manifold. 13. Open the isolation valves on the condenser. Depending on the oil type in the system, evacuate to 250 Microns. 13. Charge system with 50 pounds of Nitrogen and a little Refrigerant for a trace test. 14. Watch your gauges for a drop in pressure indicating a leak. 15. Check all fittings and any splices with a good Halogen gas detector. 16. Evacuate the system again to the point of vaporization of the oil in the compressor being careful not to boil it off. 17. Close off all ports on your manifold and install a small drier to your Refrigerant line. 18. Re-install the recovered Refrigerant, running it through the small drier on your manifold. 19. Re-check for leaks. 20. Install the electrical whip on the contacter and the control wires on the contacter coil. 21.Start the AC and check the running amps against the name plate Full Load Amps (FLA) or Regular Load Amps (RLA) and check the Refrigerant charge against the units chart. Either in your owners manual or glued to the electrical access cover.
Method 2 = Instead of recovering the refrigerant, you can pump it into the condensing unit. With your gauge manifold tied in, close the liquid line isolation valve. Run the compressor till the compound gauge reads 1 pound and close the suction line isolation valve. Doing it this way will eliminate the need for the recovery machine and heavy tanks. All else remains the same.
Special tools needed = Compound gauge (meaning it reads both pressure and vacuum). High pressure gauge, gauge manifold and at least 3 hoses, a vacuum pump, leak detector (or soap bubbles) and an amp probe. Please rate this response. Thanks for asking!
