Question

To help release moisture front the oil in a compressor's crankcase Heat the compressor. Shake the compressor. Strike the compressor with a soft object such as a rubber mallet All of the above. None of the above. To save time when evacuating a refrigeration system: Use a 2 valve, 3 hose manifold set. Use a 2 valve, 3 hose manifold set with a sight glass. Use a 4 valve, 4 hose manifold set that has a 3/8 inch hose. Use a 4 valve, 4 hose manifold set with a sight glass and glycerin filled gauges. None the above For maximum efficiency when evacuating systems with Schrader valves: Remove and discard the Schrader core. Use a 3/8 hoses at the 1/4 Schrader valves. Install piercing valves and leave them for future use. Use a valve core removing tool to remove and replace the Schrader valve core. None of the above. When evacuating a system, in order to do the best job and save time: Remove Schrader cores during the process. Use as large a hose as possible to the vacuum pump. Make certain the system has no closed valves such as solenoid valves. Run the compressor, briefly, to clear the cylinders from any trap refrigerant. All of the above

Explanation / Answer

23) Answer is a) Because when we heat the compressor the moisture is turned to vapor and evaporates preventing rust and non functioning of the Crank case

24) Answer is a) because more the vaccum the faster the evacuation of the refrigeration system is done. So less Valves and more hose should be better and a sight glass is just an add on to observe the flow of refrigerent

25) Answer is d) Valve core removing tool will facilitate to remove schrader valves and evacuate through unrestricted lines for evacuation to be faster and higher

26) Answer is e) as we know hose should be more or large , schradar removal and running compressor along with good open valves to get a proper evacuation.
