Easy conversion from vertical to
horizontal discharge
to make retro-
fit and add-on jobs easier. To convert
from vertical to horizontal discharge,
simply interchange 2 panels. The same
basic unit can be used for a variety of
applications and can be quickly modi-
fied at the jobsite. All units are factory
shipped in the vertical discharge con-
figuration for fit-up to standard roof
curbs. (One accessory curb fits sizes
004-007; another accessory curb fits
sizes 008-012.) The contractor can
order and install the roof curbs early
in the construction stage, before deci-
sions on exact size requirements have
been made.
Prepainted galvanized steel cabi-
net with baked enamel finish
is
capable of withstanding Federal Test
Method Standard No. 141 (Method
6061) 500-hour salt spray test. Paint
finish is non-chalking type. All internal
cabinet panels are primed, allowing the
entire unit to have a longer life and a
more attractive appearance.
Single continuous top panel
elimi-
nates any possibility of leaking at the
seams or gaskets, which tend to deteri-
orate over time and shift during rigging
procedures.
Heavy gage roll-formed base rails
with forklift and rigging holes
are
integral to the unit and provide easier
maneuvering and installation. Forklift
slots are on 3 sides of the unit. Stretch-
wrap packaging protects the unit dur-
ing shipment and storage.
Exclusive tool-less removal for
the filter access panel
allows the
replacement of filters without the need
for any tools.
Two-inch return-air filters
are the
standard throwaway type, easily
accessed and replaced through the fil-
ter access panel located directly above
the air intake hood.
Thru-the-bottom electrical con-
nection capability
allows power and
control wiring to be routed through the
unit basepan, thereby minimizing roof
penetrations.
Color-coded electrical wiring
per-
mits easy tracing and diagnostics.
Advanced hermetic compressors
mounted on vibration isolators
for
additional sound integrity and structur-
al support.
Enhanced copper tube, alumi-
num plate fin coils
are thoroughly
leak and pressure tested at the factory.
Outdoor coils have louvered, aluminum
lanced fins to provide maximum heat
transfer for optimum efficiency and
easy cleaning.
Refrigerant metering system
pre-
cisely controls refrigerant flow, pre-
venting slugging and floodback, while
maintaining optimum unit perfor-
mance.
Corrosion-resistant sloped con-
densate pan
reduces possibility of
biological growth and is in conform-
ance of ASHRAE (American Society
of Heating, Refrigeration, and Air
Conditioning Engineers) Standard 62
to meet many Indoor-Air Quality (IAQ)
specifications. The condensate drain
pan offers both bottom and end drain
capability to minimize roof penetra-
tions. The bottom drain can be used in
conjunction with the thru-the-bottom
connections. An external trap must be
field supplied.
Commercial duty motors with
permanently lubricated bearings
provide additional dependability.
Standard low ambient cooling
operation to 25 F;
optional head
pressure control kit available for out-
door ambient conditions to –20 F.
Factory run test printout included
with each unit,
providing certifica-
tion of the unit’s status at the time of
manufacture. Printout includes test
pressures, amperages, dates, and
inspectors. Every unit is thoroughly run
tested at the factory in each operating
mode and evacuated prior to final
charging. Every coil is then leak-tested
with helium. Automated run testing
allows accurate, undisputed tests and
measurements which are second to
none in the industry.
Ease of serviceability
on all refriger-
ant access ports allow for quick and
accurate measurements to take place.
Single-side utility connections provide
easy access to perform necessary
service. Indoor motors are accessible
through a single access door to facili-
tate servicing and adjustments after
installation. Compressors are easily
accessible for troubleshooting and
system analysis.
Carrier Apollo controls add
reliability, efficiency, and
simplification
The Apollo communicating controls
are factory-installed into the rooftop
unit control box, and come equipped
with built-in diagnostic capabilities.
Light-emitting diodes (LEDs) simplify
troubleshooting by indicating thermo-
stat commands for both stages of
heating and cooling, evaporator fan
operation, and economizer operation.
The Apollo communicating controls
are designed to work specifically with
the Carrier TEMP and VVT® (variable
volume and temperature) thermostats.
The Apollo controls allow the use of an
IAQ sensor. The Apollo controls,
combined with Carrier thermostats,
incorporate a 5-minute recycle delay
timer between modes of operation to
prevent short cycling.
