Remove and retain the four
mounting screws from the four
corners of the protective front cover,
then slowly lift the front cover,
carefully flip it over, then set it down,
upside down, to rest on the inside of
the enclosure door. Be careful as
there are still many wires connected
between the enclosure and the front
cover and there isn't a lot of slack.
Note that the two upper front cover
mounting screws are located in plain
sight in the top corners of the front
cover, while the two lower front
cover corner mounting screws are
located down in the front "well" of
the unit. Use a long screwdriver to
remove them.

Note how the three air hoses are
connected to the existing discharge
manifold, then carefully disconnect
the hoses from the existing manifold.
Refer to Figure 2. The hose in the
middle of the back or top side of the
manifold runs from the humidity
sensor. The hose on the left side of
the manifold runs to the pressure
transducer. The hose on the front or
bottom of the manifold runs to the air
out fitting. These three hoses will be
connected to the new discharge
manifold in this same arrangement.
