side open), and switch on the A/C system. The unit is equipped with a bottle heater to limit this
occurrence. When the charging operation is complete, the machine will display:
Close the high and low-pressure taps. Start the vehicle engine and the A/C system and allow
both to run for at least 3 minutes. At this point the system will be at steady state and it will be
possible to check the high and low pressure values on the relative pressure gauges.
Disconnect or close ONLY the high-pressure
A/C system still running, open the high and low pressure taps to enable the A/C system to
acquire the refrigerant contained in the hoses.

from the vehicle A/C system and switch off the engine. Turn the main switch (i) to OFF (0).
NOTE: – Should the automatic procedure be selected when the A/C system is empty, the
machine will begin with the vacuum phase. When working with A/C systems with a single

after charging.

ASSISTED PROCEDURE

RECOVERY AND RECYCLING

Connect the hoses to the A/C system with the quick-connect couplings, bearing in mind that
BLUE must be connected to the low-pressure side and RED to high pressure. If the A/C
system is equipped with a single quick-connect coupling for high or low pressure, connect only
the relative coupling and hose. Check that the high- and low-pressure taps are closed. Start
the vehicle engine and the air conditioner and allow both to run for 5 to 10 minutes with the
passenger compartment fan at full speed. Switch off the vehicle engine. Select the assisted
procedure by pressing ENTER when "Assisted Procedure" flashes on the LCD.
recovery and recycling by pressing ENTER when "Recovery/Recycling" flashes on the LCD.
Open the high and low pressure taps on the machine and press the START key to begin the
refrigerant recovery/recycling
"Recovery/Recycling". During this phase, the machine displays the quantity of refrigerant
recovered). Upon completion of recovery, the machine will stop and automatically discharge
the used oil extracted from the A/C system during the recovery phase. The oil discharge
operation lasts 4 to 12 minutes and depending on the ambient temperature. If the A/C system
pressure increases during this phase, the machine will automatically begin recovering the
refrigerant. Upon completion of discharge, the machine will check the presence of air in the
bottle, and if it's necessary to purge the non condensable gases, the alarm will sound
continuously and the display will show:
The CCST288 will automatically purge non-condensable gases (NCGS) if excess NCGS are
detected at the end of recovery. Allow the unit to complete this procedure to reduce the risk of
comebacks that can be caused by charging excess NCGS into an A/C
