3. VI EVACUATING SYSTEM Introduction Refrigeration reclaiming equipment is required Our goal in system evacuation is to remove all the non condensables possible No evacuation method will remove 100 of the moisture and air from within the refrigeration circuit Because of this guidelines and methods must be developed and adhered to ensuring only harmless amounts of contaminants remain in the system GUIDELINES WARNING DO NOT PRESSURIZE SYSTEM ABOVE 150 PSIG PRIOR TO EVACUATION OR DURING LEAK TEST PROCEDURES Use only a two stage vacuum pump 2 CFM or greater and electronic micron Evacuate from high and low sides of the system No chemical additive or alcohols are to be used to dry up a system Blow down of system with DRY NITROGEN prior to evacuation is acceptable and many times desirable See System Clean Up Evacuate to 200 microns PROCEDURE WARNING DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AT THE MAIN CIRCUIT BOX PLACE A TAG ON THE CIRCUIT BOX INDICATING THE CIRCUIT IS BEING SERVICED WARNING THIS PROCEDURE REQUIRES THE USE OF REFRIGERANTS BE CERTAIN THE WORK AREA IS WELL VENTILATED SAFETY GOGGLES AND GLOVES SHALL BE WORN SINCE REFRIGERANTS MAY CAUSE BURNS TO THE SKIN VI SERVICE PROCEDURES amp ADJUSTMENTS cont d WARNING CERTAIN PROCEDURES IN THIS SECTION REQUIRE ELECTRICAL TEST OR MEASUREMENTS WHILE POWER IS APPLIED TO THE MACHINE EXERCISE EXTREME CAUTION AT ALL TIMES IF TEST PO
