Features and Benefits Easy Access Panels Remove two screws for access to the standardized internal components and wiring. 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 of cleaning.
Features and Benefits Standardized Components • Components are placed in the same location on all Precedent™ units. Familiarize yourself with one Precedent and you are familiar with every Precedent. Flexible Applications • Only two roof curbs for the 5-10 ton Precedent line. . .simplifies curb selection. • ReliaTel microprocessor controls to meet either the simple or the more complex application. • Airflow is outstanding.
Features and Benefits • Eliminates the need for field-installed components with its built-in antishort-cycle timer, time delay relay and minimum ‘’on’’ time controls. These controls are factory tested to assure proper operation. Micro Controls 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 for Trane’s secondgeneration ReliaTel™ microprocessor controls.
Features and Benefits Factory-installed Options Hinged Access Doors These doors permit easy access to the filter, fan/heat, and compressor/control sections. They reduce the potential roof damage from screws or sharp access door corners. Economizer Equipped with either dry bulb, reference or comparative enthalpy sensing, this feature provides free cooling as the outdoor temperature and/or humidity decreases. Economizers, correctly installed, offer a valuable energy savings.
Features and Benefits Quality And Reliability Testing • 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. • 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.
Application Considerations Application of this product should be within the cataloged airflow and cooling considerations. Low Ambient Cooling The Precedent™ line features, with ReliaTel™ microprocessor controls, low ambient cooling down to 18°C (0°F). Contact your local Trane Representative for more assistance with low ambient cooling applications. Barometric Relief This product line offers an optional barometric relief damper. for use in conjunction with economizer option.
Selection Procedure - SI Units Cooling Capacity Step 1 Calculate the building’s total and sensible cooling loads at design conditions. Use the Trane calculation methods or any other standard accepted method. Factors used in unit selection: A Total Cooling Load: 16.7 kW B Sensible Cooling Load: 11.7 kW Step 3 In order to select the correct unit which meets the building’s requirements, the fan motor heat must be deducted from the gross cooling capacity.
Selection Procedure - IP Units Cooling Capacity Step 1 Calculate the building’s total and sensible cooling loads at design conditions. Use the Trane calculation methods or any other standard accepted method. Factors used in unit selection: A Total Cooling Load: 59 MBh B Sensible Cooling Load: 40 MBh Step 3 In order to select the correct unit which meets the building’s requirements, the fan motor heat must be deducted from the gross cooling capacity.

All units shall be factory assembled, internally wired, fully charged with R-22, and 100 percent run tested to check cooling operation, fan and blower rotation, and control sequence before leaving the factory. Wiring internal to the unit shall be colored and numbered for simplified identification.
Mechanical Specifications Accessories/Options Electric Heaters — Field-installed electric heat modules shall be available for installation within basic unit. Electric heater elements shall be constructed of heavy-duty nickel chromium elements internally delta connected for 200 volt, wye connected for 380-415 volt. Staging shall be achieved through the unitary control processor (UCP). Each heater package shall have automatically reset high limit control operating through heating element contactors.
Mechanical Specifications High Pressure Cutout — Standard on all units. Hinged Access Doors — Sheet metal hinges are available factory-installed on the Filter/Evaporator, Supply Fan/Heat, and the Compressor/Control Access Doors. Black Epoxy Coated Condenser Coil — The coil provides corrosion protection to condenser coils for seacoast application. The protection is a factory-applied thermoset vinyl coating, bonded to normal aluminum fin stock.
