3.0 BEFORE STARTING
Add vacuum pump oil and always check the oil level before use. Low oil level or poor quality oil will
result in premature wear and poor performance.
Install on a flat surface with adequate ventilation; allow 5cm on all sides of the pump.
Connect via a suitable hose to a manifold or suitable circuit.
Connect to a suitable safe power source using earth leakage devices when using extension cords.
CAUTION:
• Do not use with combustible, explosive, poisonous or reactive/corrosive gases.
• Do not allow dust particles to enter the pump.
• Do not allow the pump to run to open air / atmosphere for more than 3 minutes.
• Do not allow the inlet temperature of gases to exceed 80℃. Do not use in environments over 50°C.
• Not suitable for use as a compressor, transfer pump or recovery pump.
• Do not operate without oil.
• Pump surface may be hot.
• Do not block air outlet when pump is in use.
ADDITIONAL INSTRUCTIONS WHEN WORKING ON SYSTEMS WHICH USE
A2L REFRIGERANTS:
Any engineer who carries out an evacuation on a system, which utilises mildly flammable A2L
refrigerants, must be a qualified Refrigeration/Air Conditioning Technician. In addition, they must
have had training in the safe handling of flammable refrigerants, personal protective equipment, leak
prevention, handling of cylinders, charging, leak detection and the proper disposal of refrigerants.
When working with systems which utilise mildly flammable A2L refrigerants, there must be a 3 metre
exclusion zone around the equipment, during the evacuation.
Signs specifying “NO SMOKING” and other hazards should be displayed and light/electrical switches
taped over, within the exclusion zone, to prevent accidental sparks being produced. The person who
is responsible for the building, should be notified of the zone’s existence.
When servicing any equipment, the power must be isolated and switched off completely to the unit.
All equipment used during the evacuation process must be in good order, including hoses,
connectors, the vacuum gauge and the A2L CC Vacuum Pump.
