Step 6 — Adjust Factory-Installed Options
APOLLO CONTROL — The optional Apollo control is used
to actively monitor all modes of operation as well as indoor
(evaporator) fan status, filter status, and indoor-air quality. The
Apollo control is designed to work with Carrier TEMP and
VVT® (Variable Volume and Temperature) systems.
The thermostat must be wired to the Apollo control before
starting the unit. Refer to the Apollo control installation in-
structions for information on installing the thermostat. See
Fig. 12 for Apollo location.
DISCONNECT SWITCH — The optional disconnect switch
is non-fused. The switch has the capability of being locked in
place for safety purposes.
OPTIONAL DURABLADE ECONOMIZER — The option-
al economizer hood assembly is packaged and shipped in the
filter section. Damper blades and control boards are installed at
the factory and the economizer is shipped in the vertical dis-
charge position.
NOTE: Horizontal discharge block-off plate is shipped with
the air hood package. If unit is to be used for vertical discharge
application, discard this plate.
Assembly
1. Determine if ventilation air is required in building. If so,
determine the minimum amount to be supplied by each
unit and record quantity of ventilation air needed for use
in Step 8.
2. Remove filter access panel by raising panel and swinging
panel outward. Panel is now disengaged from track and
can be removed. No tools are required to remove filter ac-
cess panel. Remove outdoor-air opening panel. Save pan-
els and screws. See Fig. 13. Remove optional outdoor-air
damper hood package from filter section.
3. Assemble outdoor-air hood top and side plates as shown
in Fig. 14. Install seal strips on hoop top and sides. Put
aside screen retainer and retainer screw for later assem-
bly. Do not attach hood to unit at this time.
4. On size 012 units, install vertical discharge block-off
plate over duct openings. See Fig. 15.
5. Economizer is factory-installed in unit and secured with
screws. See Fig. 16.
NOTE: Be sure rear economizer flange is engaged under tabs
in vertical return-air opening.
6. To convert to horizontal discharge application:
a.
Rotate the economizer 90 degrees until the econo-
mizer motor faces the outdoor section (see
Fig. 17).
b.
Remove shipping screw and tape from barometric
damper.
c.
Rotate the barometric relief damper hinge
90 degrees. Barometric relief damper must open
vertically.
