Filling the Service Unit

Filling service Unit





1. Place refrigerant flask at some height, preferably place upside down (make frame). Open flask valve and allow fluid refrigerant to flow into the filling flask. The fill quantity must not exceed the maximum value (2200 g) on the lowest scale.

2. If the flask pressure is not adequate to fill the cylinder, the pressure building up can be released by opening valves 9 and 6 or 9 and 7.

3. If the cylinder is full, close the flask valve and valve 1. The unit is now ready for operation.

4. When refilling the cylinder, it is not necessary to evacuate again, if refrigerant is already flowing through the fill hose when screwing on to valve 1 (slightly open flask valve beforehand).
