Preliminary Operations; Purging Non-Condensable Gases; Automatic Procedure - FLO-DYNAMICS CCST 388 Manual De Instrucciones

EMPTY BOTTLE ALARM: Beeper and LCD advise when the quantity of refrigerant fluid
contained in the bottle is low.
SERVICE ALARM: Beeper and LCD advise whenever the total recovered refrigerant amounts
to 132 lb (60kg). To deactivate the alarm, replace the filters and the vacuum pump oil. A code
for resetting the service alarm is supplied with the spare filters.
INSUFFICIENT GAS ALARM: Beeper and LCD advise when the charging quantity set
exceeds the amount available.

PRELIMINARY OPERATIONS

Check that the main switch (i) is set to O. Check that all the MACHINE taps are closed.
Connect the MACHINE to the electrical supply and switch on. Check that the vacuum pump oil
level indicator shows at least one-half full. If the level is lower, add oil as explained in the
MAINTENANCE section. Check that in the new oil container (n) there are at least 100 cc of
the oil recommended by the manufacturer of the vehicle A/C system. Check that the oil level in
container (m) is < 200 cc. Check on the MACHINE display that there are at least 4.5 lbs (2 kg)
of refrigerant in the bottle. Should this not be the case, fill the on-board MACHINE bottle from
an external bottle of appropriate refrigerant following the procedure described in the ROUTINE
MAINTENANCE section.

PURGING NON-CONDENSABLE GASES

Before every use, check if there is air in the bottle: select the DATA MENU and read the bottle
pressure. If it is flashing, open the air purge valve (v) (to purge the non-condensable gases)
until the bottle pressure reading stops flashing.

AUTOMATIC PROCEDURE

In the automatic mode, all the operations are performed automatically: recovery and recycling,
oil discharge, vacuum, new oil replacement, and charging. The values for the quantity of gas
recovered, quantity of oil recovered, vacuum time, quantity of oil reintegrated, and quantity of
gas charged into the system are automatically printed at the end of each single operation.
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. Open both valves.
Check that the high and low-pressure taps are closed. Start the vehicle engine and switch on
the air conditioner.
compartment fan at full speed. Switch off the vehicle engine.
The machine is equipped with a 4-line LCD display, maximum 20 characters per line. On the
menus the selected line flashes; in this manual it is enclosed in quotation marks. Select the
automatic procedure; that is, press ENTER when "Automatic Procedure" flashes on the LCD.
