2 Factory shake and droptests were used as part of the packagedesign process to help assure that theunit arrives at the job site in topcondition. Rigging tests include lifting a unit intothe air and letting it drop one foot,assuring that the lifting lugs and railshold up under stress. We perform a 100% coil leak test at thefactory. The evaporator and condensercoils are leak tested at 200 psig andpressure tested to 450 psig. All parts are inspected at the point offinal assembly. Sub-standard parts areidentified and rejected immediately. Every unit receives a 100% unit run testbefore leaving the production line tomake sure it lives up to rigorous test designs at our factory not onour customers!Conversionless Units The dedicated design Units (eitherdownflow or horizontal) require nopanel removal or alteration time toconvert in the field a major costsavings during installation.

3 Horizontal Units come complete withduct flanges so the contractor doesn thave to field fabricate them. These ductflanges are a time and cost Airflow U-shaped airflow allows for improvedstatic Tight Top and Cabinet Voyager Units incorporate either a onepiece top or the Trane-Tite-Top (T3).Each part of the top (either two or threepieces) overlaps in such a way thatwater cannot leak into the unit. Theseoverlapped edges are gasketed andsealed to ensure superior waterintegrity. Quick- Access (12 -25 tons) panelsreduce the number of possible waterentry points. For added water integrity, Voyager hasa raised 11/8" lip around the supply andreturn of the downflow Units to preventwater from blowing into the And Reliability Testing The fan and idler arm assemblydesigns have been tested to over300,000 cycles each.

4 Our combinedcycle testing is now over 7,000,000cycles. All of Voyager s designs wererigorously rain tested at the factory toensure water andBenefitsReliaTel Several years ago, Trane was the first tointroduce ReliaTel into the LightCommercial Market. That design, alongwith immeasurable experience, hasprovided the technology for Trane ssecond-generation ReliaTelmicroprocessor : Provides unit control for heating, Cooling , and ventilating by utilizinginput from sensors that measureoutdoor and indoor temperature. Improves quality and reliabilitythrough the use of time-testedmicroprocessor controls and logic. Prevents the unit from short cycling,considerably improving compressorlife. Ensures that the compressor will runfor a specific amount of time, whichallows oil to return for betterlubrication, enhancing the reliability ofthe compressor.

5 Reduces the number of componentsrequired to operate the unit, therebyreducing possibilities for componentfailure. Eliminates the need for field-installedcomponents with its built-in anti-short-cycle timer, time delay relay andminimum on time controls. Thesecontrols are factory tested to assureproper operation. Requires no special tools to run the unitthrough its paces during testing. Simplyplace a jumper between Test 1 and Test2 terminals on the Low Voltage TerminalBoard and the unit will stage through itsoperational steps. The unitautomatically returns control after 60minutes to the zone sensor afterstepping through the test mode a singletime, even if the jumper is left on theunit. As long as the unit has power and theLED is lit, the ReliaTel is light indicates that the ReliaTel isfunctioning properly.

6 Features expanded diagnosticcapabilities when used with Trane sIntegrated Comfort TM Systems. As an energy benefit, softens electrical spikes by staging on fans,compressors and heaters. The Intelligent Fallback or AdaptiveControl is a benefit to the buildingoccupant. If a component goes astray,the unit will continue to operate atpredetermined temperature set points. Intelligent Anticipation is a standardfeature of the ReliaTel. Functioningconstantly, the ReliaTel and zonesensors work together in harmony, toprovide tight comfort andBenefitsStandardized Components Components are placed in the samelocation on all Voyager yourself with one Voyagerand you are familiar with everyVoyager. ReliaTel can fit all Voyager PackagedGas/Electrics, Cooling with ElectricHeat, and heat Pump models.

7 Thisprovides standardization of parts forthe contractors. Less money is tied upin inventory using the ReliaTel. Contractors/owners can stock fewerparts due to standardized componentsthroughout Voyager Side ServiceSingle side service is standard on allVoyager 12 -25 Panels On The 12 -25 TonsRemove three or fewer screws for accessto the standardized internal componentsand wiring. Easy Access Low Voltage Terminal BoardVoyager s Low Voltage Terminal Board isexternal to the electrical control is extremely easy to locate and attachthe thermostat wire. This is another costand time saving installation Voltage ConnectionsThe wiring of the low voltageconnections to the unit and the zonesensors is as simple as 1-1, 2-2, and simplified system makes it easy forthe installer to And Numbered WiringYou save time and money tracing wiresand diagnosing the When Trane s changeover VAV Systemfor light commercial applications iscoupled with Voyager, it provides thelatest in technological advances forcomfort management systems and canallow thermostat control in every zoneserved by Idler ArmWith the Quick-Adjust Idler Arm, the beltand sheaves on all 12 -25 tons can bequickly adjusted without moving themounted fan motor.

Thedual compressor models areoutstanding for humidity control, lightload Cooling conditions and systemback-up Ambient CoolingAll Voyager 12 -25 tons have coolingcapabilities down to 0 F as Exhaust OptionThis option is available on the 12 -25tons downflow Units . It provides exhaustof the return air, when using a downfloweconomizer, to maintain proper buildingpressurization. Great for relieving mostbuilding overpressurization SensingThe CO2 sensor has the ability to monitorspace occupancy levels within thebuilding by measuring the parts permillion of CO2 (Carbon Dioxide) in the the CO2 levels increase, the outside airdamper modulates to meet the CO2space ventilation requirements.

9 The CO2sensor kit is available as a field Override AccessoryWith the Ventilation Override Accessoryinstalled, the unit can be set to transitionto up to 3 different pre-programmedsequences for Smoke Purge,Pressurization, and Exhaust. Thetransition occurs when a binary input onthe RTOM is closed (shorted). This wouldtypically be a hard wired relay outputfrom a smoke detector of fire controlpanel. The ventilation override kit isavailable as a field installed Applications Only three roof curbs for the entireVoyager line simplifies curb selection. Airflow is outstanding. The Voyager canreplace an older machine with oldductwork and, in many cases, improvethe comfort through better airdistribution.
