4 Loosen the top bleeder valve by turning it counterclockwise.
NOTICE Do not loosen the bottom bleeder valve. Ensure it is tightened.
; Tip Do not completely unscrew the valve. If you do, it will come off.
5 Wait until fluid seeps out.
Fluid should seep from the open valve within 30 seconds. If no fluid
appears, ensure the corresponding cubitainer is not empty or detached from
the cart. If the cubitainer contains fluid and the fluid lines are attached and
primed, the filter might be airlocked. See Removing an Air Lock on
page 72.
6 Close the valve by turning it clockwise.
Repeat the procedure for other fluid filters to be replaced.
