Anti-backflow design Anti-backflow on the inlet prevents oil from re-entering the system in the event of a power failure, maintaining system purity.
QS5 Operating Manual 2.0 Specifications Frequency 50 Hz 60 Hz Flow (CFM) 4.5 5.0 Flow (L/min) 127 142 Motor ½ HP Inlet 3/8 in & 1/4 in Oil capacity 12.5 oz / 370 mL Net weight 23.5 lb / 10.6 kg 3.0 Safety Precautions Read this manual and become familiar with the specifications of this machine prior to use. Before operating, be sure the power supply conversion switch is set to the appropriate voltage (110V or 220V) for the power source being used.
QS5 Operating Manual The exhaust gas from the vacuum pump is composed of oil and gases from within the pump. The exhaust gas will be hot and should be well ventilated. Never operate the pump with a blocked or restricted exhaust. The resulting back pressure may blow out the sight glass or otherwise damage the pump. The QS5 has been designed to operate most efficiently on high viscosity vacuum pump oil. Other vacuum pump oil may work, but performance results may not be as stated.
QS5 Operating Manual 5.0 Start-up Procedure THE QS5 IS NOT SHIPPED WITH OIL IN ITS RESERVOIR. DO NOT START PUMP WITHOUT ADDING OIL! USE ONLY HIGH VISCOSITY VACUUM PUMP OIL, SUCH AS INFICON PART NUMBER 071-0730! 1 Place pump on flat surface. Remove oil fill cap. A coin or large flat-head screwdriver may be required. 2 Pour oil slowly to avoid over-filling and spilling. Fill to the line indicated on the oil box. NOTE: Oil level will rise when the pump warms up and reaches its operating temperature.
QS5 Operating Manual IT IS IMPORTANT THAT THE PUMP HAS REACHED ITS NORMAL OPERATIONING TEMPERATURE (50°C-70°C / 122°F-158°F) BEFORE ANY CONDENSABLE VAPORS ARE PUMPED. FAILURE TO DO THIS MAY CONTAMINATE THE OIL AND DAMAGE THE PUMP. 10 The QS5 is now ready to evacuate air conditioning and refrigeration systems. UNDER NO CIRCUMSTANCES SHOULD THE FITTINGS ON THE VACUUM PUMP BE USED FOR REFRIGERANT TRANSFER, AS DAMAGE WILL OCCUR TO THE VALVE. 6.
QS5 Operating Manual 8.0 Maintenance DISCONNECT QS5 FROM POWER SUPPLY BEFORE CARRYING OUT ANY MAINTENANCE. 8.1 Changing the Oil THE OIL MUST BE CHANGED WHEN CONTAMINATED. Evacuation of most used systems results in some contamination of the oil, causing deposits of sludge which contain water and acids. These substances will corrode your pump. Changing the oil removes damaging substances and will enhance the life of the vacuum pump. For optimum performance, change the oil after each use of the QS5.
