How to detect evaporator leak pressure? To verify if a leak exists, before removing the evaporator, a vacuum test can be performed. Using appropriate flush adapters on the evaporator fittings, pull a vacuum of 28” to 30” Hg. The evaporator should hold vacuum for 30 minutes. If there is a loss of vacuum, verify that the adapters and gauges are not the cause.
How do you check for pressure leaks? Another method of leak testing is pressurizing with gas. The gas leakage can be detected with a gas detection sensor or to look for bubbles by submerging the pressurized object in water.
How does make decide when to rebuild? GNU Make decides whether to rebuild a ‘target’ file based on the modification times of ‘dependency’ files of the target. In some cases those dependencies’ modification times can change without the contents of the files changing, thus forcing an unnecessary rebuild.
What is $@ in Makefile? $@ is the name of the target being generated, and $< the first prerequisite (usually a source file). You can find a list of all these special variables in the GNU Make manual.
