UNIT DAMAGE HAZARD Failure to follow this caution may result in equipment damage or improper operation. Deep Vacuum Method The deep vacuum method requires a vacuum pump capable of pulling a vacuum of 500 microns and a vacuum gage capable of accurately measuring this vacuum depth. The deep vacuum method is the most positive way of assuring a system is free of air and liquid water. (See Fig. 16) 5000 4500 4000 3500 3000 2500 2000 1500 1000 500 Never use the system compressor as a vacuum pump.
