5291596-YTG-E-11172 Johnson Controls Unitary Products• Full Perimeter Base Rails - The easily removable base railsprovide a solid foundation for the entire unit and protects theunit during shipment. The rails provide fork lift access fromall sides, and rigging holes are also provided so that an over-head crane can be used to place the units on a roof. Onapplications where the unit is placed on a pad, the base willkeep the unit off the pad to deter corrosion. On applicationswhere height is limited, the base rails may be removed byremoving 2 screws in each corner.• More Attractive Appearance - A single-piece top covercontaining a top-discharge outdoor fan arrangement requiresless square footage on installation and provides a wider vari-ety of installations. The one-piece design adds greater waterintegrity. Rounded corners with water drip edges add to theattractive appearance.• Top Discharge - The top-discharge outdoor fan does notdisrupt neighboring areas or dry out vegetation surroundingthe unit. The warm air from the top mounted fan is blown upand away from the structure and any landscaping. Thisallows compact location on multi-unit applications.• Outdoor Coil Grille - All models utilize a stamped slotteddesign which provides superior impact protection againstsmall objects during transit and after installation.• Low Operating Sound Level - The upward air flow carriesthe normal operating noise up and away from the living area.The rigid top panel effectively isolates noise. Isolatormounted compressor and the rippled fins of the outdoor coilmuffle the normal fan motor and compressor operatingsounds. The uniquely formed base pan also aids in soundattenuation with its structural design. This design strategi-cally places embossments in the pan for optimum strengthand rigidity.• Fan System - All models operate over a wide range ofdesign conditions with an enhanced ECM indoor fan motor.These units easily match all types of applications and pro-vide greater on-site flexibility to match comfort requirements.The cooling speed is factory-set and can be field-adjusted toa second speed. The heating speed is factory set to maintainmid point rise at the units heating input, but can be fieldadjusted. This allows maximum comfort conditions.• Simple Control Circuit - A low voltage gas heat printed cir-cuit board contains a status/diagnostic indicator light. Fieldthermostat wiring connects to color coded leads using twiston wire connections. Cooling controls use contactor andrelays for simple application and troubleshooting. Mate-n-lock plug connectors are used. The electrical control box isnot located in the compressor compartment. The controls aremounted to allow the separate access panel to be removedfor trouble shooting and maintenance without affecting thenormal system operating pressures. All wiring internal to theunit is color/number coded.• Protected Compressor - The compressor is internally pro-tected against high pressure and temperature. This isaccomplished by the simultaneous operation of scroll bypassand a temperature sensor which protect the compressor ifundesirable operating conditions occur.• Pressure Switches - A high pressure switch is standard inall units. It is an automatic reset switch. When dischargepressure reaches 650 psi, the compressor de-energizes untilpressure reaches 450 psi.• Exclusive Coil Design - Grooved copper tubes andenhanced aluminum fin construction improves heat transferfor maximum efficiency and durability for long-lasting durabil-ity and efficient operation. Indoor coils use tin-coated coppertubing with aluminum fins for effective heat transfer.• Heat Exchangers - Gas heat exchangers use corrosion-resistant, stainless-steel tubular construction to provide long-life, trouble-free operation. Gas heat exchangers are offeredwith lifetime warranties as standard with registration.• Post Purge Induced Draft Combustion - Exhausts com-bustion products from the heat exchanger upon completionof the heating cycle to prolong the heat exchanger life.• Spark To Burner Ignition - No pilot assembly required,which provides more consistent ignition in gas heating mode.This ignition is highly reliable, durable and eliminates nui-sance lockouts.• Multi Port In-shot Burners - No field adjustment is requiredto mix the air and gas for natural gas or propane use. Theseburners are constructed of high-grade corrosion-resistant,aluminized steel.• Low Maintenance - Long life, permanently lubricated out-door and evaporator fan motor bearings need no annualmaintenance, adding greater reliability to the unit. Slide-outblower assembly can be easily removed for cleaning.• Easy Service Access - Individual access panels coveringthe electrical and gas controls makes servicing easy. Remov-ing this panel will allow easy removal of the blower assemblyfor maintenance and ease of troubleshooting.• Replacement Parts - The installer requires no special train-ing to replace any of the components of these units and thenumber of new components have been reduced to minimizethe inventory of unique parts.• Loss of Charge Switch - All models include a loss of chargeswitch to provide safe shutdown of compressor.• Filter Frame Kit - All 3 phase units include a filter frame kitwhich is shipped inside the unit from production. Field instal-lation is required.• Filters - All 3 phase units include an applicable number of 1"washable filters, which are shipped inside the unit from pro-duction. Field installation is required. Three filters arerequired for the B base units.
