Handling Flammable Refrigerants

Dispose of used oil in an environmentally friendly manner

Fill used oil into pressure resistant vessels

Fill vessels with nitrogen as a protective gas and close them

Mark vessels with the warning sign 'flammable substance' W021 from ISO7010

Check for abnormal vibrations in the whole system, particularly the pipelines and capillary tubes.

Were additional safety measures required due to vibrations?

Ensure no strong vibrations are present to avoid risk of burst pipes and leakages.

Connect the pipes to the pressure equipment without load and stress to prevent mechanical stress.

Check for blocked components and pipes

Ensure sufficient volume above the liquids

Verify use of permitted refrigerants

Measure out precise quantities of refrigerant

Keep the oil temperature above 40°C

Charge the condenser or receiver directly with liquid refrigerant

Ensure blends are taken out of the charging cylinder as a bubble-free liquid

Add refrigerant on the suction side while the compressor is running
