(Unit shown with optional hail guard)
Ruud 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 serviceability that goes into each unit. Outwardly, the large Ruud
label ( 1 ) identifies the brand to the customer. The sheet-metal
cabinet ( 2 ) 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 ( 3 ), gasket-protected panels and
screws. The optional Ruud hail guard ( 4 ) is its trademark, and
sets the standard for coil protection in the industry. Every Ruud
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, fullperimeter base rails ( 5 ), 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 cover and has eliminated the worry of water entering the
conditioned space ( 6 ). The drainpan ( 7 ) is made of material
that resists the growth of harmful bacteria and is sloped for the
latest IAQ benefits. The drainpan slides out for easy cleaning.
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 fasteners, and all edges are hidden.

During development, each unit was tested to U.L. 1995, AHRI
340-370 and other Ruud-required reliability tests. Ruud adheres
to stringent IS0 9002 quality procedures, and each unit bears the
U.L. and AHRI certification labels located on the unit nameplate
( 8 ). Contractors can rest assured that when a Ruud package
unit arrives at the job, it is ready to go with a factory charge and
quality checks. Each unit also proudly displays 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 compartment, heating section, and outdoor section. Each panel is permanently embossed with the compartment name (control/filter
access, blower access and furnace access).
Control/filter blower and electric heat compartment access are
through large, hinged-access panels secured with 1/4 turn fasteners. On the outside of the panel is the unit nameplate, which
contains the model and serial number, electrical 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 quality
test assurance label is also
placed in this location ( 9 ).
The two-inch throwaway filters ( 10 ) are easily removed
11
on a tracked system for easy
replacement.

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 pulley 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, Ruud 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 requirements can be dialed in. The scroll housing ( 15 ) 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 trouble-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.
Inside the control box ( 11 ), each
electrical 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 control transformer has a low voltage circuit
breaker that trips if a low voltage
electrical short occurs.
For added convenience in the field,
a factory-installed convenience outlet ( 12 ) is 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 on the
cooling control board. The high-voltage connection is terminated at the
terminal block inside electric heat
compartment. The suggested
mounting for the field-installed
disconnect is on the exterior side
of the electrical control box.
11
The externally mounted gauge
12
ports, which are permanently identified by embossed wording that
clearly identifies the high pressure connection and the low pressure connection, extend through the compressor access panel
( 13 ). With the gauge ports mounted externally, an accurate diagnostic of system operation can be performed quickly and easily.
The blower compartment access
door is hinged and secured with 1/4
13
turn fasteners to allow easy maintenance of the blower assembly, the
entire assembly slides out by removing the 3/8" screws from the blower
retention bracket. The adjustable

The optional freeze stat refrigerant
safety device ( 16 ) is attached to
the suction line in the blower section. The freeze stat protects the
compressor if evaporator coil gets
16
too cold (below freezing) due to
low airflow or low evaporator load.
The high and low pressure
switches ( 17 ) and the optional low
ambient control are mounted on
the gauge port lines inside the
compressor access panel. The
high pressure switch will shut off
the compressor if pressure
exceeds 610 PSIG. The low
pressure switch is used for
18
loss of charge protection.
The low ambient control
allows for cooling operation
down to 0 degrees ambient
by cycling the outdoor fans.
17
Enhanced feature demand
defrost control has high and
low pressure control inputs
with unique pressure switch
logic built into the microprocessor to provide compressor and system protection without
nuisance lock-outs. LED’s on the defrost control provide diagnostic information for service personnel. ( 18 )
Inside the blower compartment the
evaporator can also be viewed. The
evaporator uses enhanced fin technology for maximum heat transfer. The
thermal expansion valve and venturi
distributor assure even distribution of
refrigerant throughout the evaporator.
Wiring throughout the unit is neatly
19
bundled and routed. Where wire harnesses go through the condenser bulkhead or blower deck, a molded wire
harness assembly ( 19 ) provides an air-tight and water-tight seal,
and provides strain relief. Care is also taken to tuck raw edges of
insulation behind sheet metal to improve indoor air quality.

The heating compartment contains the latest electric furnace
technology on the market. The 100% efficient electric furnace
can be factory-installed or easily field-installed. Built with easeof-installation in mind, the electric furnace is completely wired
for slide-in, plug-and-play installation in the field. With choices
of 15 to 40 kilowatt offerings, the contractor is assured to get
the correct amount of heating output to meet the designed
heating load.
Power hook-up in the field is easy with single-point wiring to
a terminal block ( 20 ) and a polarized plug for the low-voltage
connection ( 21 ). The electric furnace comes with fuses for the
unit ( 22 ) and for the electric furnace ( 23 ), and is UL certified ( 24 ).
The electric heating elements are of a wound-wire construction
( 25 ) and isolated with ceramic bushings. The limit switch ( 26 )
protects the design from over-temperature conditions. Each
electric furnace has the capability to be converted from singlestage operation to two-stage operation by removing a jumper
on the low-voltage terminal strip.

The compressor compartment houses the heartbeat of
the unit. The scroll compressor ( 27 ) is known for its long
life, and for reliable, quiet, and
efficient operation. The suction and discharge lines ( 28 )
are designed to absorb the
strain and stress that the
starting torque, steady state
operation, and shut down
cycle imposed on the refrigerant tubing.

A liquid line bi-flow filter drier
( 29 ) is conveniently located
near the TXV in the outdoor
section. The condenser fan
motors ( 29 ) can easily be
accessed and maintained through the unit top. The polarized
plug connection allows the motor to be changed quickly and
eliminates the need to snake wires through the unit.
The outdoor coil uses the latest enhanced fin design ( 30 ) for the
most effective method of heat transfer. Optional louvered panels
offer hail protection to outdoor coils without obstructing airflow.
Each unit is designed
for both downflow or
horizontal applications
( 31 ) for job configuration flexibility. The
32
return air compart31
ment can also contain
an economizer ( 32 ).
Two economizer models
exit, 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. The
economizer, which provides free cooling when outdoor conditions are suitable and also provides 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 CO2 setpoint.
Barometric relief is standard on all economizers.
Power Exhaust ( 33 ) is
easily field-installed. The
power exhaust is
32
housed in the
barometric relief
opening and is easily slipped in with a
33
plug-in assembly.
The Ruud roofcurb ( 34 ) is made for toolless assembly at the
jobsite by sequentially engaging the corner brackets into the
adjacent curb sides ( 35 ), which makes the
assembly process quick and easy.

Selection Procedure
RJNL-B Series
SELECTION PROCEDURE
To select an RJNL-B Heat Pump 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:
Voltage—
230 V – 3 Phase – 60 Hz
Total cooling capacity—
106,000 BTUH [31.0 kW]
*Sensible cooling capacity—
82,000 BTUH [24.0 kW]
*Heating capacity—
130,000 BTUH [38.1 kW]
*Condenser Entering Air—
95°F [35°C] DB
*Evaporator Mixed Air Entering—65°F [18.3°C] WB;
78°F [25.6°C] DB
*Indoor Air Flow (vertical)—
3600 CFM [1699 L/s]
*External Static Pressure—
.40 in. WG [.10 kPa]
2. SELECT UNIT TO MEET COOLING REQUIREMENTS.
Since total cooling is within the range of a nominal 10 ton
[35.1 kW] unit, enter cooling performance table at 95°F
[35.0°C] DB condenser inlet air. Interpolate between 63°F
[17.2 °C] and 67°F [19.4°C] WB to determine total and sensible
capacity and power input for 65°F [18.3 °C] WB evaporator
inlet air at 4000 CFM [1888 L/s] indoor air flow (table basis):
Total Cooling Capacity = 121,950 BTUH [35.71 kW]
Sensible Cooling Capacity = 102,750 BTUH [30.09 kW]
Power Input (Compressor and Cond. Fans) = 9,400 watts
Use formula in note ➀ to determine sensible capacity at 78°F
[25.6 °C] DB evaporator entering air:
102,750 + (1.10 x 3,600 x (1 – 0.05) x (78 – 80))
Sensible Cooling Capacity = 95,226 BTUH [27.88 kW]
3. CORRECT CAPACITIES OF STEP 2 FOR
ACTUAL AIR FLOW.
Select factors from airflow correction table at 3600 CFM
[1699 L/s] and apply to data obtained in step 2 to obtain
gross capacity:
Total Capacity, 121,950 x .99 = 120,731 BTUH [35.35 kW]
Sensible Capacity = 95,226 x 0.97 = 92,369 BTUH [27.05 kW]
Power Input 9,400 x .99 = 9,306 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 3600 CFM [1699
L/s]. Total ESP (external static pressure) per the spec of 0.40
in. WG [.10 kPa] includes the system duct and grilles. Add
from the table “Component Air Resistance”, 0.08 in. WG
[.02 kPa] for wet coil, 0 in. WG [.00 kPa] for downflow air flow,
for a total selection static pressure of 0.48 (0.5) in. WG
[.12 kPa], and determine:
RPM = 755
WATTS = 1,488
DRIVE = L (standard 2 H.P. motor)
10 Rely on Ruud.™
5. CALCULATE INDOOR BLOWER BTUH HEAT EFFECT
FROM MOTOR WATTS, STEP 4.
1,488 x 3.412 = 5,077 BTUH [1.49 kW]
6. CALCULATE NET COOLING CAPACITIES, EQUAL TO
GROSS CAPACITY, STEP 3, MINUS INDOOR BLOWER
MOTOR HEAT.
Net Total Capacity = 120,731 – 5,077 =
115,654 BTUH [33.86 kW]
Net Sensible Capacity = 92,369 – 5,077 =
87,292 BTUH [25.56 kW]
7. CALCULATE UNIT INPUT AND JOB EER.
Total Power Input = 9,306 (step 3) + 1,488
(step 4) = 10,794 Watts
EER =
Net Total BTUH [kW] (step 6) 115,654
=
= 10.71
Power Input, Watts (above)
10,794
8. SELECT UNIT HEATING CAPACITY.
From Heater Kit Table select kW to meet heating capacity
requirement; multiply kW x 3412 to convert to BTUH
Use 40 kW Heater Kit
Heater Kit Model: RXJJ-CC40C
Heater Kit Capacity: 131,021 BTUH [38.4 kW]
Add indoor blower heat effect (step 5) to Heater Kit Capacity to
get total heating capacity:
131,021 + 5,077 = 136,098 BTUH [39.9 kW]
9. CHOOSE MODEL
RJNL-B120CL040
*NOTE: These operating conditions are typical of a commercial application in a 95°F/79°F [35°C/26°C] design area with indoor design
