Features and Benefits Weather Tight Top and Cabinet Actual shipping tests were performed to Conversionless Units Voyager Units incorporate either a one determine packaging requirements. The dedicated design Units (either piece top or the Trane -Tite-Top (T3). Units were test shipped around the downflow or horizontal) require no Each part of the top (either two or three country to determine the best packaging. panel removal or alteration time to pieces) overlaps in such a way that Factory shake and drop tests were used convert in the field a major cost water cannot leak into the unit . These as part of the package design process to savings during installation. overlapped edges are gasketed and help assure that the unit arrives at the sealed to ensure superior water job site in top condition. Horizontal Units come complete with duct flanges so the contractor integrity. Rigging tests include lifting a unit into doesn't have to field fabricate them.

3 Quick- Access (12 -25 tons) panels the air and letting it drop one foot, These duct flanges are a time and reduce the number of possible water assuring that the lifting lugs and rails cost saver. entry points. hold up under stress. For added water integrity, Voyager has We perform a 100% coil leak test at the U-shaped Airflow a raised 1 /8" lip around the supply and 1 factory. The evaporator and condenser U-shaped airflow allows for return of the downflow Units to prevent coils are leak tested at 200 psig and improved static capabilities. water from blowing into the ductwork. pressure tested to 450 psig. All parts are inspected at the point of Quality And Reliability Testing final assembly. Sub-standard parts are The fan and idler arm assembly identified and rejected immediately. designs have been tested to over Every unit receives a 100% unit run test 300,000 cycles each. Our combined before leaving the production line to cycle testing is now over 7,000,000 make sure it lives up to rigorous Trane cycles.

4 Requirements. All of Voyager's designs were We test designs at our factory not on our rigorously rain tested at the factory to ensure water integrity. customers! 4 RT-PRC001-EN. 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 are factory tested to assure proper operation. Requires no special tools to run the unit through its paces during testing. Simply place a jumper betweenTest 1 andTest 2 terminals on the Low VoltageTerminal Board and the unit will stage through its operational unit ReliaTel automatically returns control after 60. minutes to the zone sensor after Several years ago, Trane was the first to stepping through the test mode a single introduce ReliaTel into the Light time, even if the jumper is left on the Commercial design, along unit . with immeasurable experience, has provided the technology forTrane's As long as the unit has power and the second-generation ReliaTel LED is lit, the ReliaTel is microprocessor controls.

5 Light indicates that the ReliaTel is functioning properly. ReliaTel: Features expanded diagnostic Provides unit control for heating, capabilities when used withTrane's cooling, and ventilating by utilizing input Integrated Comfort TM Systems. from sensors that measure outdoor As an energy benefit, softens electrical and indoor temperature. 'spikes'' by staging on fans, compressors and heaters. Improves quality and reliability through the use of time-tested microprocessor The Intelligent Fallback or Adaptive controls and logic. Control is a benefit to the building occupant. If a component goes astray, Prevents the unit from short cycling, the unit will continue to operate at considerably improving compressor predetermined temperature set points. life. Intelligent Anticipation is a standard Ensures that the compressor will run for feature of the ReliaTel. Functioning a specific amount of time, which allows constantly, the ReliaTel and zone oil to return for better lubrication, sensors work together in harmony, to enhancing the reliability of the provide tight comfort control.

6 Compressor. Reduces the number of components required to operate the unit , thereby reducing possibilities for component failure. RT-PRC001-EN 5. Features and Benefits Drum and Tube Heat Exchanger The heat exchanger is manufactured using aluminized steel with stainless steel components for maximum durability. The requirement for cycle testing of heat exchangers is 10,000. cycles by ANSI This is the standard required by both UL and AGA. for cycle test requirements. Trane requires the design to be tested to 2 . times this current standard. The drum and tube design has been tested and passed over 150,000 cycles, which is over 15 times the current ANSI cycling requirements. The negative pressure gas valve will not allow gas flow unless the combustion blower is operating. This is one of our unique safety features. The forced combustion blower supplies pre-mixed fuel through a single stainless steel burner screen into a sealed drum where ignition takes place.

7 It is more reliable to operate and maintain than a multiple burner system. The hot surface ignitor is a gas ignition device which doubles as a safety device utilizing a continuous test to prove the flame. The design is cycle tested at the factory for quality and reliability. Our Gas/Electric rooftops exceed all California seasonal efficiency requirements and perform even better than the California NOx emission requirements. Forced Combustion Blower Negative Pressure Gas Valve Hot Surface Ignitor Drum and Tube Heat Exchanger 6 RT-PRC001-EN. Features and Benefits Easy Access Low Voltage Terminal Board Voyager's Low Voltage Terminal Board is external to the electrical control cabinet. It is extremely easy to locate and attach the thermostat is another cost and time saving installation feature. Standardized Components Components are placed in the same Low Voltage Connections location on all Voyager Units . Familiarize yourself with one Voyager The wiring of the low voltage connections and you are familiar with every to the unit and the zone sensors is as Voyager.

8 Simple as 1-1, 2-2, and simplified system makes it easy for the installer to ReliaTel can fit all Voyager Packaged wire. Gas/Electrics, Cooling with electric Heat, Quick-Adjust Idler Arm and Heat Pump provides Colored And Numbered Wiring standardization of parts for the You save time and money tracing wires With the Quick-Adjust Idler Arm, the belt contractors. Less money is tied up in and diagnosing the unit . and sheaves on all 12 -25 tons can be inventory using the ReliaTel. quickly adjusted without moving the VariTrac mounted fan motor.
