5. With the three required people (one person on each end and one person in the

middle), rotate the heat exchanger 90° and up onto the three rectangular
packing inserts.

6. With one person holding the heat exchanger steady on the package inserts,

have another person remove the inner and outer hose access panels. Push
the panels up and out to remove them. See Figure 57. Set the hose access
panels aside.

7. Position two people on each end of the heat exchanger. Have each person

grasp and hold the under side of the heat exchanger with one hand and hold
the top of the heat exchanger with the other hand. Position the third person in
the middle of the heat exchanger and grasp the heat exchanger by the
handles. Have all three people carefully lift up the heat exchanger and walk it
in front of the rear of the rack.
