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.

About Your Heat Pump
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.

About the controls on your Zoneline. www.GEAppliances.com
Controls
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 level of comfort.
Press the + pad to raise the temperature.
Press the – pad to lower the temperature.
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.
Fan, Mode & Operation Control
FAN— sets the fan operation for HIGH, LOW
or AUTO speed. When set at AUTO, it
automatically switches between LOW and
HIGH as room temperature changes.
MODE—COOL— For cooling
FAN— For fan-only operation
HEAT— For heating
OPERATION—ON/STOP— Turns the unit on
or off. Power remains connected to the
Zoneline. The Freeze Sentinel feature still
functions if switch 6 is enabled (UP). See
the Freeze Sentinel section.
NOTE: The temperature display will flash to
indicate a possible unit malfunction. See the
Before you call for service section.

Ventilation Control
The ventilation control lever is located at the
lower 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).

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

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 switches 1–6 on the second block
of auxiliary controls. The first three switches are
used to select the cooling limits. The next three
switches are used to control the heating limits.
This feature is not available with the Remote
Thermostat–Class 2.

Heat Boost
When this switch is enabled (UP) and outdoor
temperatures are between 25° F and 46° F, heat
pump only operation is locked out. This setting is
used to provide supplementary heat to the heat
pump operation in conditions where the heat
pump only operation is not sufficient to maintain
a consistent, comfortable room temperature to
the consumer.
Diagnostics Check–For Technician’s Use Only
When this switch is enabled (UP) , the unit will go
through an operations check of all components,
which takes about 3 minutes (176 seconds).
This diagnostic tool is intended for use by
a qualified technician.

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.
