If at the end of Recovery process a sufficient vacuum has been maintained, the unit will stop, the
display (2) will indicate 'done' and the amount of refrigerant recovered will be displayed in (kg or
lb) depending on the operator’s selection.
Press 'STOP' on the console, the unit will display "busy" for 7 seconds. During “busy” time
machine will automatically drain recovered oil (separated from refrigerant) into recovered oil
vessel (7).
Conditions that will halt the recovery mode
1. Refrigerant cylinder (12) full. To protect the storage cylinder (12) being overfilled, the unit will
not allow the operator to recover refrigerant once it has reached 80% of its capacity.
2. Air conditioning system empty. If the A/C system pressure is not above atmospheric
pressure, the recovery function will not be activated.
3. High Pressure. If the operating pressure of the unit exceeds 25 bar (340 psi), the unit will stop
and display 'HigH - PrES'. The following can cause the above:
Cylinder valves not open.
Restricted cylinder hose. Check the ball valves.
Excessive high ambience temperatures.
Excessive air in refrigerant into the cylinder.
Faulty pressure control.
In all the above circumstances, press the 'STOP' key to return to the machines initial mode.
