ESSENTIAL PRE-OPERATING PROCEDURES
Before operating your SKYE machine for the first time, the following procedures must be
performed.
Your new machine and storage tank are already in a vacuum.
SET UP PROCEDURE
1. Open the storage tank vapor port (marked vapor) then locate and remove the gauge set prop
rod from the storage tank cavity.
2. Remove the yellow cover from the machine and install the gauge set prop rod using the two
holes on the right side frame channel then reinstall the yellow cover.
3. Connect the yellow (center) gauge set hose to the VAPOR INLET PORT on the back of the
machine and hang the gauge set on the prop rod.
4. Connect the machine to power and press the green ON switch button. The button will
illuminate.
5. On units equipped with a tank scale platform, press the platform down with the edge of your
foot. The green ON button light will go out.
6. Continue to hold the platform down and press the green ON button. The RED tank full light
will illuminate. Steps 5 & 6 confirm the tank full microswitch is operating properly.
7. On units equipped with a tank float, disconnect the float lead from the tank then press the
green ON button. The RED tank full light will illuminate confirming correct float operation.
YOUR MACHINE IS NOW READY FOR USE
Note: The machine must be precharged with refrigerant to, at least, 14 PSI before the
compressor will start. This can be accomplished by connecting to the vehicle AC system
to be serviced.
TO RECOVER VAPOR REFRIGERANT
▲ IMPORTANT: Before recovering refrigerant with the SKYE machine, the vehicle AC
system must be off.
NOTE: If the system contains more than 5 lbs. of refrigerant, use the liquid recovery
procedure described in the next section.
1. Connect the unit to power and open the storage tank vapor valve.
2. Connect the RED and BLUE service hoses to the AC system.
3. Press the green ON button and slowly open the BLUE (low pressure) gauge hand valve. The
compressor will start.
4. When the pressure on the BLUE (low pressure) gauge drops to 40 PSI, open the RED (high
pressure) gauge hand valve.
5. When the pressure in the AC system drops to approximately 10” VACUUM the compressor
will stop. This does not mean all the refrigerant in the system has been recovered as there
may be refrigerant trapped in the oil or an accumulator/drier that will slowly evaporate. The
compressor will restart automatically and recover this refrigerant. When the gauges remain
at 0 PSI or below for at least 2 minutes recovery is complete. Close the gauge set valves
and press the red OFF button.
