IMPORTANT SAFETY INFORMATION.
READ ALL INSTRUCTIONS BEFORE USING.
WARNING!
For your safety, the information in this manual must be followed to minimize the risk of fire or
explosion, electric shock, or to prevent property damage, personal injury, or loss of life.
■This Zoneline must be properly
installed in accordance with the
Installation Instructions before it is
used. See the Installation Instructions
in the back of this manual.
■Immediately repair or replace all
electric service cords that have become
frayed or otherwise damaged.
■Unplug or disconnect the Zoneline at
the fuse box or circuit breaker before
making any repairs.
NOTE: We strongly recommend that any
servicing be performed by a qualified
individual.

Controls
Mode Control
HIGH COOL and AUTO COOL provide
cooling with different fan speeds.
HIGH HEAT and AUTO HEAT provide
heating with different fan speeds.
LOW FAN or HIGH FAN provides air
circulation and filtering without cooling
or heating.
NOTE: If you move the switch from a cool or heat
setting to STOP or to a fan setting, the unit has an
automatic 3-minute delay before allowing the
compressor to restart in the cool or heat mode.
Temp Control
The temp control is used to maintain the
room temperature. The compressor will
cycle on and off to keep the room at the
same comfort level. When you turn the
knob to COOLER (blue) the indoor air
will become cooler. Turn the knob to
WARMER (red) and the indoor air will
become warmer.
3500 Series only
When the outdoor temperature is lower
than 25°F, heat is provided by the electric
heater in the air conditioner instead of by
the heat pump.

About the controls on your Zoneline. www.GEAppliances.com
About Your Heat Pump (3500 Series only)
Heat pumps can save money by removing heat
from the outside air—even when the outside
temperature is below freezing— and releasing
that heat indoors.
To get the best performance from your heat
pump, don’t change the room thermostat very
often. Raising the heat setting 2–3 degrees will
cause the Zoneline to use its electric heating
elements in order to reach the new temperature
setting quickly.
There is a three minute minimum compressor
run time at any setting to prevent short cycling.
The indoor fan motor starts before the
compressor and stops after the compressor
cycles off.
The electric heating elements use much
more electricity than heat pumps and cost
more to operate.

Customer Service Troubleshooting Tips Care and Cleaning Operating Instructions Safety Instructions
Ventilation Control
The ventilation control lever is located at the
upper left side of the Zoneline unit, behind the
room cabinet.
NOTE: The vent door shipping hardware must be
removed before using the vent control lever.
See the Installation Instructions in this manual.
When set at CLOSE, only the air inside the
room is circulated and filtered.
When set at OPEN, some outdoor air will be
drawn into the room. This will reduce the
heating or cooling efficiency.
Energy Tip: Keep the vent control at CLOSE.
The room air will be filtered and circulated.
Air Direction
To adjust the air direction, remove the room
cabinet. Remove the 7 louver screws that hold
the louver insert in place. Flip the louver insert
180°, replace the screws and the room cabinet.
Remove the room cabinet and flip the louver
insert to change the air direction.

Other features your Zoneline may have.
To Remove the Room Cabinet
Additional controls are located behind the
room cabinet.
To remove: Pull out at the bottom to release it
from the tabs (1). Then lift up (2).
To replace: Place the tabs over the top rail (1).
Push inward at the bottom until it snaps into
place (2).

All Electric Heat
This electric heat option functions only on the
3500 Series models. When this switch is enabled
(UP) , heat pump operation is locked out, causing
the unit to provide only electric resistance heat.
Cooling–Smart Fan
When this switch is enabled (UP) , it allows the
indoor fan to cycle on/off with the compressor.
When this switch is disabled (DOWN) , it allows
the indoor fan to run continuously.
Heating–Smart Fan
When this switch is enabled (UP) , it allows the
indoor fan to run continuously. When this
switch is disabled
(DOWN) , it allows the indoor
fan to cycle on/off with the heat pump or
heater operation.

Auxiliary controls on your Zoneline.
Remote Thermostat–Class 2
When this switch is enabled (UP) , it allows the
unit to operate off of a Class 2 Remote Control
Wall Thermostat. The unit controls are disabled.
Load Shedding (CDC)
This feature is active only if the unit is in
CDC mode. When this switch is enabled (UP) ,
the indoor fan can be turned ON or OFF with
the unit controls.
Freeze Sentinel
When this switch is enabled (UP) , it turns OFF
the freeze sentinel protection feature. With the
switch disabled (DOWN) , the freeze sentinel is
activated which automatically provides heat
without user interface. This helps to prevent
plumbing damage by turning the heater and
indoor fan ON at 41° F and OFF at 46°F.
Constant ON Fan
When this switch is enabled (UP) , it allows the
indoor fan to run continuously, at high speed,
even if the unit is in the STOP position.
Occupancy Sensor
When this switch is enabled (UP) , it allows the
unit to utilize an infrared motion sensor and
a door switch for occupancy detection. This
feature allows an energy management system
to be installed and operated in conjunction
with the unit.

Temperature Limiting
Temperature limiting can reduce energy costs
by limiting the lowest temperature that can be
set for cooling and the highest temperature that
can be set for heating. Temperature limiting is
controlled by the second six auxiliary switches.
The first three switches are used to select the
cooling limits and the remaining three switches
are used to control the heating limits. This
feature is not available with the Remote
Thermostat–Class 2.

Auxiliary controls on your Zoneline.
Auxiliary Controls–Terminal Connections
The auxiliary controls are located behind the
room cabinet beneath the control panel.
Remove the room cabinet. See the
To Remove the Room Cabinet section.
Remove the screw from the control panel
corner.
Remove the control panel and knobs by
grasping the control panel on both sides and
pulling forward. The knobs will pull off with
the control panel.
After all desired settings have been made,
replace the control panel, knobs and room
cabinet by reversing steps 1–3. NOTE: The
knob stem is Dshaped. Install the flat of the
shaft to the flat of the knob.
The owner is responsible for making all
connections and setting the appropriate
dip switches.
Insert the building hook-up wires into the
bottom of the terminal and tighten screw
securely to make the desired connections.
CAUTION:
Improper wiring may damage the Zoneline
electronics. No common busing is permitted.
Damage or erratic operation may result.
A separate wire pair must be run from each
separate controlling switch to each individual
Zoneline.

Care and cleaning.
Base Pan
In some installations, dirt or other debris may be
blown into the unit from the outside and settle in
the base pan (the bottom of the unit).
In some areas of the United States a “jell-like”
substance may be seen in the base pan.
Check it periodically and clean, if necessary.
Outdoor Coils
The coils on the outdoor side of the Zoneline
should be checked regularly. If they are clogged
with dirt or soot, they may be professionally
steam cleaned, a service available through your
GE service outlet. You will need to remove the
unit to inspect the coils because the dirt
build-up occurs on the inside.
Clean the outside coils regularly.
Room Cabinet and Case
Turn the Zoneline off and disconnect the
power supply.
To clean, use water and a mild detergent.
Do not use bleach or abrasives. Some commercial
cleaners may damage the plastic parts.
