STEP 75
Open the air valve 1/2 to 3/4 turn.
IMPORTANT: Do not exceed this rate of air delivery.
This rate delivers one gallon per minute of flush
solvent which is ideal for the orifice openings in the
circuit being flushed.
Turn the flushing valve to the FLUSH position and
flush the circuit until the solvent appears clear at the
return hose to the solvent waste container.
STEP 76
Close the flushing and air valves. Reverse hose
connections for forward flushing. Connect the hose
from the flush tank to the discharge line; connect the
hose to the return bucket to the suction line. Open
flushing and air valves and repeat flushing until the
solvent is clear.
STEP 77
Turn the flushing valve to the AIR position. Allow air
to flow through the circuit until no noticeable mist is
discharged.
NOTE: Air pressure is the only means to remove the
flushing solvent from the A/C system, and no solvent
must remain in the system when it is evacuated and
recharged.
