Note
1. Peel off the pipe cover carefully. The cover will be needed again when
putting the units together.
2. When loading the unit on an elevator, place the separated sections up-
right as shown below. (Place the right side up.) Place a piece of wood at
the bottom of the bottom section for support to keep it level.

To put the top and bottom sections of the unit together, follow the procedures above
in the reverse order.
• Check to make sure that the frame is perpendicular to the horizontal plane
before putting the panels together.
• When the frames will not fit back into place, loosen bolt 2 as shown in
[Fig.10.0.1], place the frames, and tighten bolt 2.
• Be sure to securely tighten all screws and bolts. (tightening torque: 74N·m)
• Using [Fig.10.0.5] and Table 1 as a reference, connect all connectors correctly.
Use a cable tie and bundle the wires as they were before.
• Keep torch flame away from the insulation material on the drain pan and from
other flammable materials when performing brazing work. Use the shielding
board that is supplied.
• If the front panels are not even when they are attached to the unit and are
closed, adjust the panels to make them even (applicable to Model 500 only).
• Perform a test run and check for abnormal sound, rattling, and water leaks.

Caution:
• Use a hand-lift truck to transport the units; they are heavy even when the
top and button sections are separated.
- Carrying the units by hand is dangerous and may result in personal injury if
the units fall or topple over.
• Exercise caution not to get your fingers caught when separating or as-
sembling the top and bottom sections of the unit.
