Refrigerant: Service and Repair
Refrigerant Leak Repair
If the system has lost all charge due to a leak:
1. Evacuate the system. (See procedure.)
2. Charge the system with approximately one pound (16 oz) of refrigerant.
3. Check for leaks.
4. Discharge the system.
5. Repair leaks.
CAUTION: Replacement filter-drier units must be sealed while in storage. The drier used in these units will saturate water quickly upon exposure
to the atmosphere. When installing a drier, have all tools and supplies ready for quick assembly to avoid keeping the system open any longer than
necessary.
6. Replace receiver drier.
7. Evacuate and charge system.
LOW CHARGE
If the system has not lost all of its refrigerant charge; locate and repair all leaks. If it is necessary to increase the system pressure to find the leak (because
of an especially low charge) add refrigerant. If it is possible to repair the leak without discharging the refrigerant system, use the procedure for correcting
low refrigerant level.
HANDLING TUBING AND FITTINGS
Kinks in the refrigerant tubing or sharp bends in the refrigerant hose lines will greatly reduce the capacity of the entire system. High pressures are
produced in the system when it is operating. Extreme care must be exercised to make sure that all connections are pressure tight. Dirt and moisture can
enter the system when it is opened for repair or replacement of lines or components. The following precautions must be observed. The system must be
completely discharged before opening any fitting of connection in the refrigeration system. Open fittings with caution even after the system has been
discharged. If any pressure is noticed as a fitting is loosened, allow trapped pressure 10 bleed off very slowly.
Never attempt to rebend formed lines to fit. Use the correct line for the installation you are servicing. A good rule for the flexible hose lines is keep the
radius of all bends at least 10 times the diameter of the hose.
Sharper bends will reduce the flow of refrigerant. The flexible hose lines should be routed so that they are at least 80 mm (3.1 inches) from the exhaust
manifold. It is good practice to inspect all flexible hose lines at least once a year to make sure they are in good condition and properly routed. Unified
plumbing connections with O-rings, these O-rings are not reusable.
