Assisted Procedure; Recovery And Recycling - FLO-DYNAMICS CCST 388 Manuel D'utilisation

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 quick-connect coupling. Then, with the A/C
system running, open the high and low pressure taps to allow the A/C system to draw the
refrigerant contained in the hoses.
machine taps and the low side coupling. Then
machine from the vehicle A/C system and switch off the engine. Turn the main switch (i) to
OFF (0).
NOTE: The automatic procedure may be run even if the A/C system is empty. In this case the
machine will begin with the vacuum phase. When working with A/C systems with a single
high-pressure coupling, set the charging quantity 3 - 4 oz (100g) in excess of the required
quantity, since in this case it will be impossible to recover the residual refrigerant from the
hoses.

ASSISTED PROCEDURE

In the assisted procedure mode, all the operations can be performed individually. The values
for the quantity of gas recovered, oil recovered, vacuum time, oil added, and gas charged into
the system are automatically printed at the end of each operation.

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 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.
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, in pounds (lbs) or, grams (g). Upon completion of recovery, the machine will stop
and discharge while automatically displaying the used oil extracted from the A/C system during
the recovery phase. The oil discharge operation lasts 4 to 12 minutes and depending of
ambient temperature. If any residual refrigerant in the A/C system should increase in pressure
during this phase, the machine will automatically begin recovering the refrigerant. Upon
completion of discharge, the machine will check the presence of air into the bottle, and if it's
necessary to purge the non condensable gases, the alarm will sounds continuously and the
display will shows:
The CCST388 will automatically purge non-condensable gases (NCGS) if excess
NCGS are detected at the end of recovery. Allow the unit to complete this
