Hose/Line HVAC: Service and Repair
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 refrigerant oil will absorb moisture readily out of the air. This
moisture will convert into acids within a closed system.
CAUTION:
-
The system must be completely empty before opening any fitting or connection in the refrigeration system. Open fittings with caution even after
the system has been emptied. If any pressure is noticed as a fitting is loosened, retighten fitting and evacuate the system again.
-
A good rule for the flexible hose lines is to 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 they are at least 3 inches (80 mm) from the exhaust manifold. Inspect all flexible
hose lines to make sure they are in good condition and properly routed.
-
The use of correct wrenches when making connections is very important. Improper wrenches or improper use of wrenches can damage the fittings.
The internal parts of the A/C system will remain stable as long as moisture-free refrigerant and refrigerant oil is used. Abnormal amounts of dirt,
moisture or air can upset the chemical stability. This may cause operational troubles or even serious damage if present in more than very small
quantities.
-
When opening a refrigeration system, have everything you will need to repair the system ready. This will minimize the amount of time the system
must be opened. Cap or plug all lines and fittings as soon as they are opened. This will help prevent the entrance of dirt and moisture. All new
lines and components should be capped or sealed until they are ready to be used.
-
All tools, including the refrigerant dispensing manifold, the manifold gauge set, and test hoses should be kept clean and dry.
