WARNING
To prevent injury to personnel, stand clear of ball receiver when applying air pressure. Hose
may jump when ball arrives at ball receiver.
NOTE
If displacement ball gets stuck in hose, straighten kinks in hose. It may be necessary to increase
air pressure. Do not exceed 150 psi.
(12) Pressurize air supply hose (14) to 80 to 90 psi. Displacement ball (11) will be forced through
hose (2), displacing any residual water. A sound will be heard when displacement ball reaches
ball receiver.
(13) Shut off air supply when displacement ball (11) enters caged reducer (17).
(14) Remove quick disconnect coupling clamp (18) and separate caged reducer (17) from reducer
(16). Remove displacement ball (11) from caged reducer.
(15) Remove coupling clamp (1) and separate reducer (16) from end of hose (2).
Evacuation. Refer to figure 2-36.
(16) Connect cap (2) to hose (3) with coupling clamp (1).
(17) Connect ejector (5) to ball inlet (6).
(18) Connect air supply hose (4) to ejector (5).
(19) Pressurize air supply hose (4) to ejector (5).
(20) Shut off air supply to ejector (5) when hose (3) has collapsed.
(21) Disconnect air supply hose (4) from ejector (5).
(22) Disconnect ejector (5) from ball inlet (6).
(23) Remove coupling clamp (1) and disconnect cap (2) from hose (3).
(24) Remove coupling clamp (4, figure 2-35) and separate nipple (10) and attached parts from hose
(2).
(25) Repeat steps (3) through (23) for hose (5), except work from upline end of hose to downline end
to prevent having to move air compressor.
(26) Repeat steps (3) through (24) for all remaining downline hoses while removing coupling clamps
(7) and swivels (8) from hoses (9) where required.
(27) Pack evacuation kit components in storage chest.
