Features and
Benefits
The Genius line was built to provide not
only ultimate indoor comfort but also
the comfort of knowing that our self-
contained units are reliable as well as
easy to install and maintain.
Genius is the most flexible vertical self-
contained of the market. Suitable to use
in offices, residences or restaurants.
Available as water cooled, integrated air
cooled (or package unit) or with remote
air coded condenser; the modern design
of the Genius line allows you, for the first
time, to select the color of the unit.
Why Consider Self-Contained
Floor-by-Floor Systems?
Improved Cash Management
•Factory installed options and testing:
Reduces field labor and installation risk
and improves system reliability
•Requires less sophisticated maintenance
than built-up systems
Tenant Satisfaction
•Complete HVAC system on each floor or
area minimizes tenant inconvenience
during routine maintenance.
•Tenants can control system after hours
to increase productivity and minimize
expense
Low First Cost
•Factory packaged controls and piping
reduce field labor, installation time and
cost
•Flexible arrangement to match most
building configurations
Lower Installed Cost
•Single point power connection
•Single point water connection
•Factory commissioned and tested
controls
•Factory installed options
Economical Operation
•Floor-by-floor system results in energy
savings since only air conditioners on
floors requiring cooling need to operate
•Annual system energy consumption
comparable to central chilled water
system but with significant energy
consumption reduction during partial
occupancy and after-hours
Assured Acoustical Performance
•Horizontal discharge plenum provides
smooth airflow, reducing static pressure
losses for optimum acoustical
performance.
•Scroll compressor design smooths gas
flow for quieter operation
Micro Controls
Trane was the first to introduce
Microelectronics to commercial unitary
products and has continued to expand
its application to other products.
The new self-contained with Micro
provides the highest performance,
reliability and best serviceability in the
industry. Trane, a world class
manufacturer can provide this winning
combination for your facility.
The Trane Micro, provided as a factory
installed option, was designed with two
thoughts in mind: reliability and comfort.
The Micro accurately orchestrates all
other system operations whether it is
heating or cooling.
Since it is factory mounted it will provide
smooth, trouble-free start-up.
The microprocessor provides powerful
operation and diagnostic information.
The micro eliminates the need for a field
installed anti short-cycle timer and time
delay relays, which are an integral part
of the micro controller.
The IAQ standard, the microelectronics
and the simplified maintenance
capability were all considered a priority
during the design phase of this self-
contained unit.

Benefits
Air Handling Section
In accordance to the ASHRAE Standard
62-89 for Indoor Air Quality, Trane has
developed an exclusive and innovative
design for the drain pan. This design
insures proper drainage, preventing
conditions of water stagnation that could
result in microbial growth.
All the air handlers feature a factory
installed belt drive and ball bearing
evaporator fan with adjustable shelves.
The unit can be installed indoors; the
condenser air can be ducted to the
outside or installed in a remote location.
For free horizontal application, the
optional discharge plenum with
aluminum grills insures a quiet
operation and maintains the aesthetics
of the units.
In the return section an optional
aluminum grill grants an easy and
elegant installation.
3 Filter Types
To meet Commercial and Industrial
needs you can select the filter media for
the application.
Nylon Electrostatic Filters
Wire Mesh Permanent Filters
Throwaway Filters
Many other options available as special
(Contact your local Trane
Representative).
Scroll Compressor
offers significant efficiency and reliable
benefits. With fewer moving parts than
comparable reciprocating compressors,
there is less internal friction and
therefore greater efficiency. A smooth
compressor cycle, due to the low torque
variation, creates less stress on the
motor for greater reliability and
efficiency.
How the Scroll Compressor Works
General
The compressor has two scrolls. The top
scroll is fixed and the bottom scroll
orbits. Each scroll has walls in a spiral
shape that intermesh.
Inlet — First Orbit
As the bottom scroll orbits, two
refrigerant gas pockets are formed and
enclosed.
Compression — Second orbit
The refrigerant gas is compressed as the
volume is reduced closer to the center of
the scroll.
Discharge — Third Orbit
The gas is compressed further and
discharged through a small port in the
center of the fixed scroll.

Features and
Benefits
Integrated Self-Contained Systems:
Profitable, Simple
Integrated Comfort™System (ICS)
Trane’s Integrated Comfort™system
improves job profit and increases job
control by combining Trane self-
contained units and a Tracker®building
management system. This integrated
system provides total building comfort
and control. The primary motivation for
building owners/managers in making the
purchasing decision of an HVAC controls
system is no longer just saving energy; it
is having the ability to automate their
facilities and the convenience of interface
to control systems.
As an additional benefit the Micro
allows the Genius to be integrated to
the Tracker. This ability allows the
multiple units to be controlled and
diagnosed from a central location, from
across town or even across the country.
Just imagine the HVAC installed in your
facility capable of being scheduled,
monitored and let you know when it is
having problems.
Genius is three times ingenious in many
ways.

Selection
Procedure
The selection of a Genius self-contained
unit can be accomplished in three easy
steps.
1
LOAD: Determine the load requirements
for heating and cooling (include outside
air) using Trane’s load estimate forms,
TRACE®Easy/600 or any standard
method.
2
UNIT TYPE: Self-contained air
conditioners are available in either
water-cooled or remote air-cooled
models to match individual needs.
3
SELECT THE UNIT: The conditions under
which the unit must operate and the
design load will give the final selection.
SELECTION EXAMPLE
Design Conditions
Water-cooled unit
Entering air temperature — 80/67 F
Total gross capacity required —
55,000 BTUH
Entering water temperature — 85 F
Leaving water temperature — 92 F
Airflow — 1,950 CFM at 0.5” duct static
pressure.
Voltage
Unit Selection
Tentatively select a 5-ton unit — Model
SAVE050. Refer to Table PD-6 to obtain
gross total and sensible unit capabilities,
gpm, and leaving water temperature at
nominal conditions:
Total MBh — 60.6
Sensible MBh — 43.5
GPM — 14.5
LWT — 95
The SAVE-050 meets the total and
sensible design requirements.
Since the difference between entering
and leaving water is 7°F multiply the
capacities and water flow by correction
factors on Capacity Correction Factor
Table.
Cooling capacity multiplier 1.01
Sensible capacity multiplier 1.05
Water flow multiplier 1.39
60.6 x 1.01 = 61.21 MBh
43.5 x 1.01 = 43.94 MBh
14.5 x 1.39 = 20.16 GPM
Refer to Table PD-1 to determine
approximate brake horsepower and fan
rpm:
1035 rpm and 0.66 bhp.
Determine net capacities by subtracting
fan motor heat from gross capacities:
2.8 x 0.66 bph = 1.85 MBh
Net total capacity =
61.21 - 1.85 = 59.36 MBh
Net sensible capacity =
43.94 - 1.85 = 42.09 MBh
Supply air temperature DB
Qs= 1.085 x CFM x (Tr-TS)
42,090 = 1.085 x 1950 x (80-TS)
TS= 80 - 42,090
(1.085) (1950)
