In the evacuation mode the air and moisture in the air
conditioning system is removed and exhausted to the
atmosphere. The evacuation mode runs for a predetermined
time selected by the operator.
To initiate evacuation mode, press the 'UP' key twice, followed by the 'START' key. Select the
desired evacuation duration by pressing the 'UP' key to increase or 'DOWN' key to decrease time
duration.
(example value only)
Once the desired time has been selected press the 'START' key and the function will commence.
Note: During evacuation mode hand valves (4) on the console must be open.
The evacuation time can be set from one minute to eight hours.
At any time the evacuation time can be paused or cancelled by pressing the stop button once to
pause, or twice to cancel the function.
The unit has a unique function that if the evacuation function is selected and there is residual
refrigerant in the air conditioning system, greater then 0.5 bar or 9 psi, the unit would detect this
condition, whereby it will beep six times to warn the operator. After this warning the unit will
automatically recover the residual refrigerant once it has recovered the entire refrigerant it will
start the selected evacuation function automatically.
Note: After the evacuation process is completed, close both hand valves on console (4).
By closing the valves the unit is "isolated" from the A/C system to allow for monitoring of
any possible vacuum leak that may exist in the air- conditioning system. This is achieved
by monitoring the suction and discharge gauges.
