Page 10: Operation
Switch the Unit ON at the mains socket. The unit will start to recover refrigerant. You will hear the HC-3 click as it recovers refrigerant. When the entire liquid refrigerant has been recovered the clicking will stop and the pressure on the unit gauge will begin to fall. When the inlet pressure reaches 0 bar the unit compressor will automatically stop. -

At the same time the unit will discharge into the plant which will raise the pressure. The pressure difference between the plant and the cylinder will result in refrigerant transfer. You will hear the HC-3 click as it recovers refrigerant. -
Page 12: Hints And Tips
Avoid the use of extension cables if possible as this will lower the voltage at the unit and reduce the performance of the unit and can cause overheating. Always transport the unit in an upright position. © 2020 RDA Environmental Engineering Ltd HC-3 Hydrocarbon Refrigerant Recovery Unit Operation Manual Issue 2 UK Version 2020... - Page 13 Use a separate recovery cylinder dedicated for each type of refrigerant and have an extra cylinder for unknown refrigerants and refrigerant recovered from compressor burn-outs. © 2020 RDA Environmental Engineering Ltd HC-3 Hydrocarbon Refrigerant Recovery Unit Operation Manual Issue 2 UK Version 2020...
