Abstract
A method, system and device provides for the conversion of a mini-split AC unit to a mini-split AC unit with quick connect pre-charged ends. Quick connect fittings are placed onto the AC unit lines after the nitrogen pre-charge is released from the liquid line. A fitting tool/device having one or more fittings and valves is attached to the liquid line. A vacuum pump attached to the fitting tool/device vacuums the evaporator until its micron level falls and stays below 500 microns. Then, a refrigerant line attached to the fitting tool/device adds approximately 1 ounce of refrigerant to the evaporator.
Claims20
A device comprising:
- a body portion having a fluid passageway therethrough;
- a first fitting at a first end of the body portion, wherein the first fitting is adapted to connect to a quick connect AC line;
- a second fitting at a second end of the body portion, wherein the second fitting is adapted to connect to a vacuum hose.
A system for converting an AC unit into a quick connect AC unit, the system comprising:
- an AC unit having an evaporator and AC lines;
- quick connectors for attaching to the AC lines;
- a fitting tool/device for attaching to one of the quick connector, wherein the fitting tool/device has at least three fittings;
- a vacuum pump and hose for attaching to the fitting tool/device;
- a refrigerant supply and supply line for attaching to the fitting tool/device;
- and
- a micron gauge for attaching to the fitting tool/device.
A method for converting an AC unit having an evaporator and two AC lines into a quick connect AC unit, comprising the steps of:
- releasing nitrogen from the evaporator;
- attaching a quick connect fitting onto each of the two AC lines;
- attaching a fitting tool/device having at least three fittings onto one of the quick connect fittings via a first of the at least three fittings;
- attaching a vacuum pump line to a second of the at least three fittings on the fitting tool/device;
- attaching a micron gauge to a third of the at least three fittings on the fitting tool/device;
- vacuuming the evaporator until the micro gauge reads and stays below 500 microns.
