6IntroductionThis manual is designed to provide product, performanceand application information to our customers and theirarchitects and engineers for use in selection and designof a zonal comfort control system utilizing GE Zoneline ®Packaged Terminal Air Conditioners (PTAC) and PackagedTerminal Heat Pumps (PTHP). GE Zoneline PTACs and PTHPsare self-contained units designed for through-the-wallinstallations in hotels, motels, apartments, hospitals,nursing homes, add-on rooms and many other installations.Zoneline units provide individual room or zone control in bothcooling and heating operation. There is a model for practicallyevery application, ranging in cooling capacity from 7,200 to14,800 BTUH and heating capacity from 6,400 to 14,000 BTUHin heat pump operation. See pages 42 and 54 for resistanceheaters available.Zoneline offers a two-tier lineup: The Deluxe Line consists ofthe 4100 Series with electric resistance heat, the 4100 SeriesDry Air 25 Models with enhanced dehumidification for hotand humid climates and the 6100 Series heat pump. The6100 Series heat pump features reverse cycle defrost andsimultaneous supplemental resistance heat, when needed,to maintain room comfort. Both offer tactile touch controlswith digital display and optional corrosion protection.Deluxe Line Standard Features:• Two-fan-motor system with Indoor Cross-FlowBlower for quieter operation• Digital Controls—LED Temperature Display—Easy Temperature Selection—Tactile Touch Pad• Universal Heaters• Heat Sentinel• “L” Coil Design Condenser• 3-Position Vent Door• Freeze Sentinel™• Indoor Coil Frost Control• Central Desk Control Interface• Remote Thermostat Control Interface• Random Restart• Electronic Temperature Limiting• “Smart Fan” Fan Cycle/Continuous Control• Transfer Fan Interface• Reverse Cycle Defrost and SimultaneousSupplemental Resistance Heat on Heat Pumps• Quick Heat RecoveryDeluxe Line Optional Features:• Corrosion Protection• Internal Condensate Removal (on 6100 SeriesHeat Pump without Corrosion Protection)NOTE: Dry Air 25 models include all the standard features of the4100 Series plus standard corrosion protection.Advantages of the GE Zoneline System:• Flexible Application—May be installed from flush to finished floor to3" from the ceiling—7,200 to 14,800 BTUH units in same physical size—Deluxe 4100 and 6100 Series may be ducted tocondition more than one room—Compatible with Class 2 remote thermostat control—Compatible with 2-wire CDC or many EnergyManagement Systems• Economical Installation—No ductwork necessary—No mechanical equipment rooms or pipes requiredfor heating/cooling units—Replacement units fit existing 42"-wide by 16"-highwall cases• Quiet Operation—Indoor cross-flow blower• Energy-Saving Operation—Units in unoccupied areas may be turned off—Designed for efficient cooling operation — EERs from10.6 to 13.2—Efficient heat pump units — COPs from 3.3 to 4.0—Extended heat pump operation without sacrificingroom comfort• Ease of Maintenance—Permanently lubricated fan motors—Upfront lift-out interchangeable filters—Slide-out chassis for easy access for cleaning or ifservice is required• Reverse Cycle Heat Pump OperationThe 6100 Series heat pumps utilize the unique GE PTACheat pump operation to ensure a comfortable room.The logic used by the units is the same logic used bycentral system heat pumps to provide greater savings.
