6.10 Rear Standoff (RSO)
We recommend the use of ¾” x #10 round head self-tapping
sheet metal screws to fasten the accessories to the unit.
Care should be taken to protect the painted finish when
handling the unit and accessories.
1. On a clean, flat, unobstructed floor surface, lay out the
pieces of the standoff relative to the positions they
are to be installed, shown in the Installation/Assembly
Drawings sent with the unit.
2. Clamp the angle brace so it is flush to the top, back edge
of top cover. Fasten the angle brace with four evenly
spaced screws. (This will be used at a later step to fasten
the unit to the wall.)
3. Due to slight variations in the unit widths, it is best to
assemble the RSO on the unit rather than preassembling
the RSO and then fastening it to the unit.
4. Position the vertical classroom unit directly in front of its
final installation position. Allow enough room behind the
unit for the RSO and some room to work. (Once the RSO
is mounted it may become more difficult to relocate the
Air Handler.)
5. Place the Side Panel against the back of the unit in the
orientation shown and square up the corners and edges
and then securely fasten the panel to the unit using
½” x #10 round head self-tapping sheet metal screws.
Place screws through the 1” front mounting flange of the
standoff panel into the back of the unit at approximately
18” apart or in the starting holes provided.
6. Repeat with opposite side panel.
7. Place top cover on top of the installed side panels
with the angle brace toward the wall side (rear) of the
assembly. Square up the corners and edges of both
pieces and securely fasten the top cover to the unit and
to the top edge of each side panel
8. Place bottom cover in position between the installed
side panels along the floor. Square up the corners and
edges of both pieces and securely fasten the side panels
to the bottom cover. Do not mount the RSO to the unit
through the top or bottom cover of the standoff. (If this
unit has packaged air conditioning these may interfere
with the removal of the exhaust fan during future service
maintenance.)
NOTE:
When the vertical classroom unit is fitted
with a rear standoff (RSO) or rear plenum
assembly (RPA) it becomes necessary
to fasten the unit to the wall by using a
supplied 2” x 2” x 34” 18ga. Angle brace,
that must be secured to the top cover of the
RSO assembly as described below.
