Features and  
Benefits  
Easy-Adjust Idler Arm  
With the Easy-Adjust Idler Arm, the belt  
and sheaves can be quickly adjusted  
without moving the mounted fan motor.  
The result is a major savings in time and  
money.  
Patented Condenser Coil  
Precedent boasts a patented 1+1+1  
Hybrid coil, permanently gapped for  
easy cleaning.  
Unit Cabinet  
The compact cabinet with rounded  
corners takes up less room and is less  
costly to ship. The beveled and ribbed  
top is not only aesthetically pleasing, it is  
designed to prevent water from pooling  
Colored And Numbered Wiring  
You save time and money tracing wires  
and diagnosing the unit.  
Single Point Power  
A single electrical connection powers the  
unit.  
Convertible Units  
• The units ship in a downflow  
configuration. They can be easily  
converted to horizontal by simply  
moving two panels.  
• Units come complete with horizontal  
duct flanges so the contractor doesn’t  
have to field fabricate them. These duct  
flanges are a time and cost saver.  
Sloped Drain Pans  
Every Precedent unit has a non-  
corrossive, removable, double-sloped  
drain pan that’s easy to clean and  
reversible to allow installation of drain  
trap on either side of the unit.  
Compressors  
Precedent™ contains the best compressor  
technology available to achieve the  
highest possible performance. Our  
compressor line includes Trane-built  
Climatuff™ reciprocating and scrolls.  
Through the Base Condensate  
Every unit includes provisions for  
through the base condensate drain  
connections. This allows the drain to be  
connected through the roof curb instead  
of a roof penetration.  
Easy Access Panels  
Easy access panels reduce the number of  
possible water entry points. Remove two  
screws for access to the standardized  
internal components and wiring.  
Foil-Faced Insulation  
All panels in the Evaporator section of  
the unit have cleanable foil-faced  
insulation. All edges are either captured  
or sealed to ensure no fibers get into the  
airstream.  
Low Ambient Cooling  
Unit Base  
All Precedent units have cooling  
capabilities down to -18°C (0°F) as  
standard.  
For added water integrity, Precedent has  
a raised 29 mm 1(1/8") lip around the  
unit’s downflow supply and return to  
prevent water from blowing into the  
ductwork.

Features and  
Benefits  
Standardized Components  
Flexible Applications  
• Components are placed in the same  
location on all Precedent™ units.  
Familiarize yourself with one Precedent  
and you are familiar with every  
Precedent.  
• Only two roof curbs for the 5-10 ton  
Precedent line… simplifies curb  
selection.  
• Airflow is outstanding. The Precedent  
can replace an older machine with old  
ductwork and, in many cases, improve  
comfort through better air distribution.

supply fan motors meet a wide airflow  
range.  
• Precedent offers ultimate flexibility.  
Options and components are not pre-  
packaged at the factory. Units are built  
to order in our standard “ shortest in  
the industry” ship cycle time.  
Easy Access Low Voltage Terminal  
Board  
Precedent’s Low Voltage Terminal Board  
is external to the electrical control  
cabinet. It is extremely easy to locate and  
attach the thermostat wire. This is  
another cost and time saving installation  
feature.  
Low Voltage Connections  
The wiring of the low voltage  
connections to the unit and the zone  
sensors is as simple as 1-1, 2-2, and 3-3.

Features and  
Benefits  
• Eliminates the need for field-installed  
components with its built-in anti-  
short-cycle timer, time delay relay  
and minimum ‘’on’’ time controls.  
These controls are factory tested to  
assure proper operation.  
• Requires no special tools to run the  
Precedent unit through its paces  
during testing. Simply place a  
jumper between Test 1 and Test 2  
terminals on the Low Voltage  
Micro Controls  
Terminal Board and the unit will walk  
through its operational steps. The  
unit automatically returns control to  
the zone sensor after stepping  
through the test mode a single time,  
even if the jumper is left on the unit.  
Several years ago,Trane was the first to  
introduce microprocessor controls into  
the Light Commercial Market. That  
design, along with immeasurable  
experience, has provided the technology  
forTrane’s second-generation ReliaTel™  
microprocessor controls.

Quality And Reliability Testing  
• We perform a 100% coil leak test at the  
factory.The evaporator and condenser  
coils are leak tested at 1,375 kPa (200  
psig) and pressure tested to 3,100 kPa  
(450 psig).  
• All Precedent™ designs were rigorously  
rain tested at the factory to ensure  
water integrity.  
• Actual shipping tests were performed  
to determine packaging requirements.  
Units were test shipped around the  
country to determine the best  
packaging.  
• All parts are inspected at the point of  
final assembly. Sub-standard parts are  
identified and rejected immediately.  
• Every unit receives a 100% unit run test  
before leaving the production line to  
make sure it lives up to rigorous Trane  
requirements.  
• Factory shake and drop tests were  
used as part of the package design  
process to help assure that the unit  
arrives at the job site in top condition.  
We test designs at our factory not on  
our customers!  
• Rigging tests include lifting a unit into  
the air and letting it drop one foot,  
assuring that the lifting lugs and rails  
hold up under stress.

Application  
Considerations  
Application of this product should be  
within the cataloged airflow and cooling  
considerations.  
Condensate Trap  
The evaporator is a draw-thru  
configuration. A trap must be field  
provided prior to start-up on the cooling  
cycle.  
Low Ambient Cooling  
Precedent™ features, as standard, low  
ambient cooling down to -18°C (0°F).  
Contact your localTrane Representative  
for more assistance with low ambient  
cooling applications.  
Clearance Requirements  
The recommended clearances identified  
with unit dimensions should be  
maintained to assure adequate service,  
maximum capacity and peak operating  
efficiency. Actual clearances which  
appear inadequate should be reviewed  
with the localTrane sales personnel.  
Barometric Relief  
This product line offers an optional  
barometric relief damper for use in  
conjunction with economizer option.  
This option consists of gravity dampers  
which open with increased pressure. As  
the building air pressure increases, the  
pressure in the unit return air section  
also increases, opening the dampers  
and relieving the conditioned space.  
Unit Pitch  
These units have reversible sloped  
condensate drain pans. Units must be  
installed level, any unit slope must be  
toward side of unit where condensate  
drain is connected.  
NOTE: THE EFFECTIVENESS OF  
BAROMETRIC RELIEF DAMPER  
DURING ECONOMIZING OPERATION  
IS SYSTEM RELATED.  
PRESSURE DROP OF THE RETURN AIR  
SYSTEM SHOULD BE CONSIDERED TO  
CONTROL BUILDING PRESSURIZA-  
TION.

Cooling Capacity  
Table PD-1 shows that a WSC060AD has  
a gross cooling capacity of 18.1 kW and  
14.7 kW sensible capacity at 35 degree C  
ambient and 3,400 m3/hr with 27 DB/19  
WB air entering the evaporator.  
Heating Capacity  
Step 1  
Step 1  
Calculate the building heating load using  
the Trane calculation form or other  
standard accepted method.  
Calculate the building’s total and  
sensible cooling loads at design  
conditions. Use the Trane calculation  
form or any other standard accepted  
method.  
To find the net cooling capacities, fan  
motor heat must be subtracted.  
Determine the total unit static pressure:

Step 3  
1.144 x (Fan kW) + 0.132  
= 1.144 x 0.75 + 0.132 = 1.0 kW  
Because 8.3 kW is less than the  
building’s required heating capacity at  
winter design conditions, a  
supplementary heater must be selected.  
16 kW – 8.3 kW = 7.7 kW

2,000 cfm and 0.78 inches,Table PD-9a  
shows 1.00 bhp.  
Airflow: 2,000 cfm  
Use the portion ofTable PD-5a for the

Sensible Cooling Load: 33 MBh  
Fan Motor Heat (MBh) =  
Step 3  
2.915 x (Fan bhp) + 0.451  
= 2.915 x 1.00 + 0.451 = 3.37 MBh  
Because 29.1 MBh is less than the  
building’s required heating capacity at  
winter design conditions, a  
supplementary heater must be selected.  
50 MBh – 29.1 MBh = 29.9 MBh
