System Empty
- Evacuate the refrigerant system to the lowest degree of vacuum possible (approximately -88 kPa (- 26 in. Hg) or greater vacuum), (Refer to REFRIGERANT SYSTEM EVACUATE) . Determine if the system holds a vacuum for 15 minutes. If vacuum is held, a leak is probably not present. If system will not maintain vacuum level, proceed to step 2.
- Prepare and dispense 0.284 kilograms (10 ounces) of R-134a refrigerant into the evacuated refrigerant system, (Refer to REFRIGERANT SYSTEM CHARGE) and proceed to step 1 under SYSTEM LOW procedure.
