Rheem Package equipment is designed from the ground up with
the latest features and benefits required to compete in today’s
market. The clean design stands alone in the industry and is a
testament to the quality, reliability, ease of installation and service-
ability that goes into each unit. Outwardly, the large Rheem Com-
mercial SeriesTM label ( ) identifies the brand to the customer.
The sheet-metal cabinet ( ) uses nothing less than 18-gauge
material for structural components with an underlying coat of
G90. To ensure the leak-proof integrity of these units, the design
utilizes a one-piece top with a 1/8" drip lip ( ), gasket-protected
panels and screws. The Rheem hail guard ( ) is its trademark,
and sets the standard for coil protection in the industry. Every
Rheem package unit uses the toughest finish in the industry,
using electro deposition baked-on enamel tested to withstand a
rigorous 1000-hour salt spray test, per ASTM B117.
Anything built to last must start with the right foundation. In this
case, the foundation is 14-gauge, commercial-grade, full-perime-
ter base rails ( ), which integrate fork slots and rigging holes to
save set-up time on the job site. The base pan is stamped, which
forms a 1-1/8" flange around the supply and return opening and
has eliminated the worry of water entering the conditioned space
( ). The drainpan ( ) is made of material that resists the
growth of harmful bacteria and is sloped for the latest IAQ bene-
fits. The insulation has been placed on the underside of the
basepan, removing areas that would allow for potential moisture
accumulation, which can facilitate growth of harmful bacteria. All
insulation is secured with both adhesive and mechanical fasten-
ers, and all edges are hidden.
During development, each unit was tested to U.L. 1995, ANSI
21.47, ARI 340-370 and other Rheem-required reliability tests.
Rheem adheres to stringent IS0 9002 quality procedures, and
each unit bears the U.L. and ARI certification labels located on
the unit nameplate ( ). Contractors can rest assured that when
a Rheem package unit arrives at the job, it is ready to go with a
factory charge and quality checks. Each unit also proudly dis-
plays the “Made in the USA” designation.
Access to all major compartments is from the front of the unit,
including the filter and electrical compartment, blower compart-
ment, furnace section, and outdoor section. Each panel is per-
manently embossed with the compartment name (control/filter
access, blower access and furnace access).
Electrical and filter compartment access is through a large, tool-
less, hinged-access panel. On the outside of the panel is the unit
nameplate, which contains the model and serial number, electri-
cal data and other important unit information.
The unit charging chart is located on the inside of the electrical
and filter compartment door. Electrical wiring diagrams are found
on the control box cover,
which allows contractors
to move them to more
readable locations. To
the right of the control
box the model and serial
number can be found.
Having this information
on the inside will assure
model identification for
the life of the product.
The production line qual-
ity test assurance label is
also placed in this loca-
tion ( ). The two-inch
throwaway filters ( )
are easily removed on a
tracked system for easy
replacement.

UNIT FEATURES & BENEFITS—RKKB/RKMB/RKNB- SERIES

Inside the control box ( ), each electri-
cal component is clearly identified with
a label that matches the component to
the wire diagram for ease of trouble
shooting. All wiring is numbered on
each end of the termination and color-
coded to match the wiring diagram. The
integrated furnace control, used to con-
trol furnace operation, incorporates a
flashing LED troubleshooting device.
Flash codes are clearly outlined on the
unit wiring diagram. The control trans-
former has a low voltage circuit breaker
that trips if a low voltage electrical short
occurs. There is a blower contactor
and compressor contactor for each
compressor.
For added convenience in the field, a
factory-installed convenience outlet and
disconnect ( ) are available. Low and
High voltage can enter either from the
side or through the base. Low-voltage
connections are made through the low-
voltage terminal strip. For ease of
access, the U.L.-required low voltage
barrier can be temporarily removed for
low-voltage termination and then rein-
stalled. The high-voltage connection is
terminated at the high-voltage terminal
block. The suggested mounting for the
field-installed disconnect is on the exte-
rior side of the electrical control box.
To the right of the electrical and filter
compartment are the externally
mounted gauge ports, which are perma-
nently identified by embossed wording
that clearly identifies the compressor
circuit, high pressure connection and
low pressure connection ( ). With the
gauge ports mounted externally, an
accurate diagnostic of system operation can be performed
quickly and easily.
The blower compartment is to the right of the gauge ports and
can be accessed by removing 5/16" washer-head screws. This
panel is not hinged to assure a water-tight fit with the unit. To
allow easy maintenance of the blower assembly, the entire
assembly easily slides out by removing two 3/8" screws from the
blower retention bracket. The adjustable motor pulley ( ) can
easily be adjusted by loosening the bolts on either side of the
motor mount. Removing the bolts allows for easy removal of the
blower pulley by pushing the blower assembly up to loosen the
belt. Once the belt is removed, the motor sheave can be adjusted
to the desired number of turns, ranging from 0 to 6 turns open.
Where the demands for the job require high static, Rheem has
high-static drives available that deliver nominal airflow up to 2" of
static. By referring to the airflow performance tables listed in the
installation instructions, proper static pressure and CFM require-
ments can be dialed in. The scroll housing ( ) and blower scroll
provide quiet and
efficient airflow.
The blower
sheave is secured
by an “H” bushing
which firmly
secures the pulley
to the blower shaft
for years of trou-
ble-free operation.
The “H” bushing
allows for easy
removal of the
blower pulley from
the shaft, as
opposed to the
use of a set screw, which can score the shaft, creating burrs that
make blower-pulley removal difficult.

UNIT FEATURES & BENEFITS—RKKB/RKMB/RKNB- SERIES

Also inside the blower compart-
ment is the low-ambient control
( ), low-pressure switch ( ),
high-pressure switch ( ) and
freeze stat refrigerant safety
device ( ). The low-ambient
control allows for operation of the
compressor down to 0 degrees
ambient temperature by cycling
the outdoor fans on high pressure.
The high-pressure switch will
shut off the compressors if
pressures exceeds, 450 PSIG
are detected, this may occur if
the outdoor fan motor fails. The
low-pressure switch shuts off
the compressors if low pressure
is detected due to loss of
charge. The freeze stat protects
the compressor if the evapora-
tor coil gets too cold (below
freezing) due to low airflow. Each factory-installed option is
brazed into the appropriate high or low side and wired appropri-
ately. Use of polarized plugs and sharder fittings allow for easy
field installation.
Inside the blower compartment the interlaced evaporator can
also be viewed. The evaporator uses enhanced fin technology for
maximum heat transfer. The cap-tube metering device assures
even distribution of refrigerant throughout the evaporator.
Wiring throughout the unit
is neatly bundled and
routed. Where wire har-
nesses go through the
condenser bulkhead or
blower deck, a molded wire
harness assembly ( )
provides an air-tight and
water-tight seal, and pro-
vides strain relief. Care is
also taken to tuck raw
edges of insulation behind sheet metal to improve indoor air
quality.
The furnace compartment contains the latest furnace technology
on the market. The draft inducers ( ) draw the flame from the
Rheem exclusive in-shot burners ( ) into the aluminized tubular
heat exchanger ( ) for clean, efficient gas heat. Stainless steel
heat exchangers can be factory installed for those applications
that have high fresh-air requirements, or applications in corrosive
environments. Each furnace is equipment with a two-stage gas
valve ( ), which provides two stages of gas heat input. The first
stage operates at 50% of the second stage (full fire). 81% steady
state efficiency is maintained on both first and second stage by
staging the multiple inducers to optimize the combustion airflow
and maintain a near stioceometric burn at each stage.
The direct spark igniter ( ) assures reliable ignition in the most
adverse conditions. This is coupled with remote flame sense ( )
to assure that the flame has carried across the entire length of
the burner assembly. Gas supply can be routed from the side or
up through the base.
Each furnace has the following safety devices to assure consis-
tent and reliable operation after ignition:
• Pressures switches ( ) to assure adequate combustion airflow
before ignition.
• Rollout switches ( ) to assure no obstruction or cracks in the
heat exchanger.
• A limit device that protects the furnace from over-temperature
problems.

UNIT FEATURES & BENEFITS—RKKB/RKMB/RKNB- SERIES

The compressor compartment houses the heartbeat of the unit.
The scroll compressor ( ) is known for its long life, and for
reliable, quiet, and efficient operation. The suction and discharge
lines are designed with shock loops ( ) to absorb the strain and
stress that the starting torque, steady state operation, and shut
down cycle impose on the refrigerant tubing. Each compressor
and circuit is independent for built-in redundancy, and each circuit
is clearly marked throughout the system. Each unit has two
stages of efficient cooling operation, first stage is approximately
50% of second stage.
The condenser fan motor ( ) can easily be accessed and main-
tained by removing the protective fan grille. The polarized plug
connection allows the motor to be changed quickly and elimi-
nates the need to snake wires through the unit.
The outdoor coil uses the latest enhanced fin design ( ) for the
most effective method of heat transfer. The outdoor coil is pro-
tected by louvered panels, which allow unobstructed airflow while
protecting the unit from both Mother Nature and vandalism.
Each unit is
designed for both
downflow or hori-
zontal applications
( ) for job config-
uration flexibility.
The return air
compartment can
also contain an
economizer ( ). Two
models exits, one for downflow
applications, and one for horizontal
applications. Each unit is pre-wired for the
economizer to allow quick plug-in installation. The
economizer is also available as a factory-installed option. Power
Exhaust is easily field-installed. The economizer, which provides
free cooling when outdoor conditions are suitable and also pro-
vides fresh air to meet local requirements, comes standard with
single enthalpy controls. The controls can be upgraded to dual
enthalpy easily in the field. The direct drive actuator combined
with gear drive dampers has eliminated the need for linkage
adjustment in the field. The economizer control has a minimum
position setpoint, an outdoor-air setpoint, a mix-air setpoint, and a
CO2setpoint. Barometric
relief is standard on all
economizers. The power
exhaust is housed in the
barometric relief opening
and is easily slipped in with
a plug-in assembly.
The Rheem roofcurb
( ) is made for
toolless assembly at
the jobsite by sequen-
tially engaging the
corner brackets into the
adjacent curb sides ( ), which makes the
assembly process quick and easy.

UNIT FEATURES & BENEFITS—RKKB/RKMB/RKNB- SERIES

To select an RKKB- Cooling and Heating unit to meet a job
requirement, follow this procedure, with example, using data
supplied in this specification sheet.
1. DETERMINE COOLING AND HEATING REQUIREMENTS
AND SPECIFIC OPERATING CONDITIONS FROM PLANS
AND SPECS.
Example:
Total cooling capacity— 205,000 BTUH [60.1 kW]
Sensible cooling capacity— 155,000 BTUH [45.4 kW]
Heating capacity— 235,000 BTUH [68.9 kW]
*Condenser Entering Air— 95°F [35°C] DB
*Evaporator Mixed Air Entering— 65°F [18°C] WB;
78°F [26°C] DB
*Indoor Air Flow (vertical)— 7200 CFM [3398 L/s]
*External Static Pressure— .70 in. WG
2. SELECT UNIT TO MEET COOLING REQUIREMENTS.
Since total cooling is within the range of a nominal 20 ton
[70.3 kW] unit, enter cooling performance table at 95°F [35°C]
DB condenser inlet air. Interpolate between 63°F [2°C] and
67°F [19°C] to determine total and sensible capacity and
power input for 65°F [18°C] WB evap inlet air at 7400 CFM
[1888 L/s] indoor air flow (table basis):
Total Capacity = 232,700 BTUH [68.2 kW]
Sensible Capacity = 186,500 BTUH [54.66 kW]
Power Input (Compressor and Cond. Fans) = 21,600 watts
Use formula in note ➀to determine sensible capacity at 78°F
[26°C] DB evaporator entering air:
Sensible Capacity = 172,500 BTUH [50.55 kW]
3. CORRECT CAPACITIES OF STEP 2 FOR ACTUAL
AIR FLOW.
Select factors from airflow correction table at 7200 CFM
[3398 L/s] and apply to data obtained in step 2 to obtain
gross capacity:
Total Capacity, 232,700 x .995 = 231,540 BTUH [67.86 kW]
Sensible Capacity, 172,500 x .987 = 170,260 BTUH [49.90 kW]
Power Input 21,600 x .999 = 21,578 Watts
These are Gross Capacities, not corrected for blower motor
heat or power.
4. DETERMINE BLOWER SPEED AND WATTS TO
MEET SYSTEM DESIGN.
Enter Indoor Blower performance table at 7200 CFM
[3398 L/s]. Total ESP (external static pressure) per the spec of
.70 in. includes the system duct and grilles. Add from the table
“Component Air Resistance,” .15 for wet coil, .05 for downflow
air flow, for a total selection static pressure of .900 (.9) inches
of water, and determine:
RPM = 942
WATTS = 4,717
DRIVE = M (standard 7.5 H.P. motor)
5. CALCULATE INDOOR BLOWER BTUH HEAT EFFECT
FROM MOTOR WATTS, STEP 4.
BTUH = 4,717 x 3.412 = 16,094
6. CALCULATE NET COOLING CAPACITIES, EQUAL TO
GROSS CAPACITY, STEP 3, MINUS INDOOR BLOWER
MOTOR HEAT.
Net Total Capacity = 231,540 – 16,094 =
215,446 BTUH [63.14 kW]
Net Sensible Capacity = 170,260 – 16,094 =
154,166 BTUH [45.18 kW]
7. CALCULATE UNIT INPUT AND JOB EER.
Total Power Input = 21,578 (step 3) + 4,717
(step 4) = 26,295 Watts
EER = Net Total BTUH [kW] (step 6) =215,446 = 8.19
Power Input, Watts (above) 26,295
8. SELECT UNIT HEATING CAPACITY.
From Physical Data Table read that gas heating output
(input rating x efficiency) is:
Heating Capacity = 243,000 BTUH [71.2 kW]
*NOTE: These operating conditions are typical of a commercial applica-
tion in a 95°F/79°F [35°C/26°C] design area with indoor design
of 76°F [24°C] DB and 50% RH and 10% ventilation air, with
the unit roof mounted and centered on the zone it conditions
by ducts.
