The following two steps (6 and 7) require extreme caution to ensure the black pressure sensor
(U3) is not damaged.
6. Remove the adjustable nozzle by gently pulling it upward until it comes out of
the left side retaining clips. When the left side is out, pull the nozzle to the left
to completely remove it from its cradle. (See Figure 5.7.)
7. Carefully disconnect the 1/8" OD black tubing coming from the back of the
unit to the limiting orifice. (See Figure 5.8.)
