The RA16 is our 16 SEER air conditioner and is part of the Ruud
air conditioner product line that extends from 13 to 20 SEER.
This highly featured and reliable air conditioner is designed for
years of reliable, efficient operation when matched with Ruud
indoor aluminum evaporator coils and furnaces or air handler
units with aluminum evaporators.
Our unique composite base ( ) reduces sound emission, elimi-
nates rattles, significantly reduces fasteners, eliminates corro-
sion and has integrated brass compressor attachment inserts
()
. Furthermore it has incorporated into the design, water
management features, means for hand placement () for unit
maneuvering, screw trays () and inserts for lifting off unit
pad. ( )
Service Valves ( ) are rigidly mounted in the composite base
with 3" between suction and discharge valves, 4" clearance
below service valves and a minimum of 5" above the service
valves, creating industry leading installation ease. The minimum
27 square-inches around the service valves allows ample room
to remove service valve schrader prior to brazing, plenty of
clearance for easy brazing of the suction and discharge lines to
service valve outlets, easy access and hookup of low loss refrig-
erant gauges ( ), and access to the service valve caps for
opening. For applications with long-line lengths up to 250 feet
total equivalent length, up to 200 feet condenser above evapora-
tor, or up to 80 feet evaporator above condenser, the long-line
instructions in the installation manual should be followed.
Controls are accessed from the corner of the unit by removing
only two fasteners from the control access cover, revealing the
industry’s largest 15" wide and 14" tall control area () . With all
this room in the control area the high voltage electrical whip ( )
can easily be inserted through the right size opening in the bot-
tom of the control area. Routing it leads directly to contractor
lugs for connection. The low voltage control wires () are easily
connected to units low voltage wiring. If contactor or capacitor
( ) needs to be replaced there is more than adequate space to
make the repair. Furthermore, if high pressure and low pressure
model was not purchased but is desired to be installed in the
field, the service window ( ) can be removed by removing two
screws, to access the high and low side schrader fittings for easy
field installation. The entire corner can be removed providing
ultimate access to install the high and low pressure switch. ()
If in the rare event, greater access is needed to internal compo-
nents, such as the compressor, the entire corner of the unit can
be removed along with the top cover assembly to have unprece-
dented access to interior of the unit () . Extra wire length is
incorporated into each outdoor fan and compressor so top
cover and control panel can be positioned next to the unit. With
minimal effort the plug can be removed from the compressor
and the outdoor fan wires can be removed from the capacitor to
allow even more uncluttered access to the interior of the unit () .
Outdoor coil heights range from as short as 27" to 48", aiding
access to the compressor. Disassembly to this degree and com-
plete reassembly only takes a first time service technician less
than 10 minutes. ( )
All units utilize strong formed louver panels which provide indus-
try leading coil protection. Louver removal for coil cleaning is
accomplished by removing one screw and lifting the panel out of
the composite base pan. () All RA16 units utilize single row
coils ( ) making cleaning easy and complete, restoring the
performance of the air conditioner back to out of the box perfor-
mance levels year after year.
The outdoor fan motor has sleeve bearings and is inherently
protected. The motor is totally enclosed for maximum protection
from weather, dust and corrosion. Access to the outdoor fan is
made by removing four fasteners from the fan grille. The outdoor
fan can be removed from the fan grille by removing 4 fasteners
in the rare case outdoor fan motor fails.
Each cabinet has optimized composite ( ) fan orifice assuring
efficient and quiet airflow.

The entire cabinet has powder post paint ( ) achieving 1000
hour salt spray rating, allowing the cabinet to retain its aesthetics
throughout its life.
Scroll compressors with standard internal pressure relief and
internal thermal overload are used on all capacities assuring
longevity of high efficient and quiet operation for the life of the
product.
Each unit is shipped with filter drier for field installation and will
trap any moisture or dirt that could contaminate the refrigerant
system.
All cabinets have industry leading structural strength due to the
composite base pan () , interlocking corner post ( ), formed
curved louver panels ( ) and drawn top cover ( ) making it
the most durable cabinet on the market today.
Each RA16 capacity has undergone rigorous psychometric test-
ing to assure performance ratings of capacity, SEER
and EER per AHRI Standard 210/240 rating condi-
tions. Also each unit bears the UL mark and each unit
is certified to UL 1995 safety standards.
Each unit has undergone specific strain and modal testing to
assure tubing () is outside the units natural frequency and that
the suction and discharge lines connected to the compressor
withstand any starting, steady state operation or shut down
forces imposed by the compressor.
All units have been sound tested in sound chamber to AHRI 270
rating conditions, and A-weighted Sound Power Level tables
produced, assuring units have acceptable noise qualities (see
page 8). Each unit has been ran in cooling operation at 95°F and
82°F and sound ratings for the RA16 range from as low as 70.7
dBA to 76.6 dBA.
All units have been ship tested to assure units meet stringent
“over the road” shipping conditions.
As manufactured all units in the RA16 family have cooling capa-
bility to 55 °F. Addition of low ambient control will allow the unit
to operate down to 0°F. Factory testing is performed on each
unit. All component parts meet well defined specification and
continually go through receiving inspections. Each component
installed on a unit is scanned, assuring correct component uti-
lization for a given unit capacity and voltage. All condenser coils
are leak tested with pressurization test to 550#’s and once
installed and assembled, each units’ complete refrigerant
system is helium leak tested. All units are fully charged from the
factory for up to 15 feet of piping. All units are factory run tested.
The RA16 has a 10-year conditional compressor and parts war-
ranty (registration required).
