C.Flush Discharge/Suction Hose Set and Liquid Lines/Hoses (Off Car) -
FIGURE 3 - HOSE SET FLUSHING
a.
Force liquid R-11 into the discharge/suction hose compressor manifold block openings (do hoses one at a time) until clean R-11 flows
from the other end of the hose, see Figure 3. Also force liquid R-11 into the liquid lines and any other air conditioning hoses until clean
R-11 flows from the other end of the line or hose. Flush off any debris that is on the expansion (orifice) tube. Either the small orifice
nozzle flush gun J-33883-15 or large orifice nozzle flush gun J-33883-50 may be used. Drain into a suitable waste container.
b.
Cap all line and hose ends with air conditioning hose end caps or appropriate plugs. Wait a minimum of 5 minutes before removing caps
and draining the lines and hoses.
c.
Force R-12 vapor into the hose ends (end opposite of the compressor manifold block) to purge the remaining R-11, see Figure 3.
Position the hose muffler such that all R-11 will be purged. Likewise, purge the liquid lines and other hoses and with R-12. Use the large
orifice nozzle flush gun J-33883-50 or equivalent. Continue to blow R-12 vapor until no liquid is observed leaving the compressor
manifold block, line or hose ends.
Where applicable, inspect for debris stuck on the high and low side refrigerant temperature sensors or pressure switches.
