Introduction
This manual is designed to provide product, performance
and application information to our customers and their
architects and engineers for use in selection and design of a
zonal comfort control system utilizing GE Zoneline
®
Packaged Terminal Air Conditioners (PTAC) and Packaged
Terminal Heat Pumps (PTHP). GE Zoneline
®
PTACs and
PTHPs are self-contained units designed for through-the-wall
installations in hotels, motels, apartments, hospitals, nursing
homes and add-on rooms.
Zonelines provide individual room or zone control in both
cooling and heating operation. There is a model for
practically every application, ranging in cooling capacities
from 7,100 to 14,700 BTUH and heating capacities from
6,400 to 13,400 BTUH in heat pump operation. See page 54
for resistance heaters available.
The Zoneline offers a two tier lineup; the Deluxe Line - the
2500 Series with electric resistance heat, including the Dry
Air 25 Models with enhanced dehumidification for hot and
humid climates, and the 3500 Series heat pump; the
Premium Line - the 5500 Series heat pump.
Deluxe Line Standard Features:
• Freeze Sentinel
TM
• Indoor Coil Frost Control
• Central Desk Control Interface
• Standard Remote Thermostat Control Capability
• Random Restart
• Electronic Temperature Limiting
• “Smart Fan” Fan Cycle/Continuous Control
• Transfer Fan Interface
• Separate Indoor and Outdoor Fan Motors
• Room Occupancy Sensor Interface
NOTE: The Dry Air 25 models include all features of the
2500 series.
Premium Line Standard Features:
• All the Standard Features of the Deluxe Line
• Exclusive Simultaneous Heat Pump and Resistance
Heat Operation (when needed)
• Exclusive Reverse Cycle Defrost to Increase Heat Pump
savings
• Touch Pad Controls with Digital Temperature Readout
Advantages of the GE Zoneline
®
System:
• Flexible Application
• May be installed flush to finished floor to 3" from the
ceiling
• 7,100 to 14,700 BTUH units in same physical size
• Deluxe 2500 and 3500 Series may be ducted to
condition more than one room
• Compatible with Class 2 Remote Thermostat Control
• Compatible with 2 wire CDC and many Energy
Management systems
• Economical Installation
• No ductwork necessary
• No mechanical equipment rooms or pipes required for
heating/cooling units
• Replacement units fit existing 42" wide by 16" high wall
cases
• Quiet Operation
• Auto Fan operates unit at lowest, quietest fan speed
when possible to reduce the sound from the unit
• Indoor double cut-off scroll: two fan motor 2500 and
3500 Series units
• Indoor cross-flow blower: 2 fan motor 5500 Series units
• Energy-Saving Operation
• Units in unoccupied areas may be turned off
• Designed for efficient cooling operation - EERs from
9.6 to 12.0
• Efficient heat pump units - COPs from 3.1 to 3.5
• Extended heat pump operation without sacrificing
room comfort
• Ease of Maintenance
• Permanently lubricated fan motors
• Upfront lift out filters
• Air Discharge area is easily accessed for cleaning -
Deluxe Series
• Slide out chassis for easy access if service is required
• Heat Pump Operation (Defrost Termination)
After the heat pump models have switched to resistance heat
they will change back to heat pump operation as the
outdoor temperature rises - the 3500 series returns to heat
pump operation at 37°F outdoor coil temperature, and the
5500 series returns to heat pump operation at 32°F outdoor
air temperature.
