NOTE
Vacuum specifications listed are for sea level conditions.
Subtract 3.4 kPa (34 mbar) (1 in Hg) from 98 kPa (980
mbar) (29 in Hg) for each 300 m (1000 ft) elevation above
sea level.
6. Evacuate system until low-pressure gauge registers
specified vacuum.
If specified vacuum cannot be obtained in 15
minutes, a leak may be present. Locate and repair
leak. (See “R134a REFRIGERANT LEAK TEST” on
page 15-5.)
