Press the VACUUM key. Automatic will show on the
display. VACUUM will appear on the display and after
a slight delay, the vacuum pump will star t. The
display will show the amount of time programmed
and begin a countdown to zero.
When the programmed time has elapsed, an
automatic hold occurs. Check the low pressure
gauge to see that the A/C system maintains a 28 to
29-1/2 inches of mercury (Hg).
NOTE: The low pressure gauge must not increase
faster than one inch of mercury (Hg) in 15 minutes. If
the system will not hold vacuum, a leak exists that
must be corrected before recharging can begin. See
leak test information in this section.
STEP 43
IMPORTANT: Do not inject the PAG oil until the
system will hold a proper vacuum.
OEM1415 has an injection system to return new SP-
20 PAG oil equal to the amount recovered at the end
of the evacuation process.
To add the new oil, adjust the O-ring around the oil
return bottle to the required oil charge level.
NOTE: If 2.4 oz (71 ml) was recovered in the oil
reservoir, 2.4 oz (71 ml) of new SP-20 PAG must be
returned.
Open the oil injection valve to add the oil into the
system. Close the valve when the oil level reaches
the O-ring.
IMPORTANT: Do not let oil level fall below the dip
tube in the return bottle or air will be introduced into
the refrigerant circuit.
