■Product must be operated with
the electrical plug supplied with the
product. Do not replace the electrical
plug supplied with the product.
■If the receptacle does not match the plug,
the receptacle must be changed out by
a qualified electrician.
■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.
■All air conditioners contain refrigerants,
which under federal law must be
removed prior to product disposal.

The dip switch controls are located behind
the front case panel, through an opening
on the front of the unit.
To access the dip switches, remove the front
case panel by removing the filter, taking out
the four front screws, the upper two screws from
the top of the panel and the shipping screws on
each side, if present. (Discard the two side shipping
screws, if present).
NOTE: The owner is responsible for setting
the appropriate dip switches and connecting
terminals.

Controls–dip switches.
Freeze Sentinel (Requires room air sensor kit–RAVRMS)
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 fans ON at 41° F and OFF at 46° F.
Constant ON Fan
When this switch is enabled (UP), it allows the fan
to run continuously.
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.

The duct select function allows the indoor
fan to be operated at two variable fan speeds.
When this switch is enabled (UP), the unit
automatically selects either high or middle fan
speed (for longer ductwork applications). When set
in the down position, the unit is automatically
operated in either the middle or low fan speed
(for shorter ductwork applications).

Temperature Limiting (Requires room air sensor kit–RAVRMS)
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 top 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.

Controls—terminal connections.
Controls–Terminal Connections
The terminal connections are located behind
the front case panel through an opening
on the front of the unit.
To access the terminal connections, remove
the front panel by removing the filter, taking out
the four front screws, the upper two screws from
the top of the panel and the shipping screws on
each side, if present. (Discard the two side shipping
screws, if present.)
Insert the building hook-up wires into the bottom
of the terminals and tighten screws securely
to make the desired connections.
Route the wires from the terminal connections
through the unit wire guides and out through
the case wire guide.
NOTE: The owner is responsible for setting
the appropriate dip switches and connecting
terminals.
CAUTION:
Improper CDC wiring may damage the Zoneline
electronics or cause erratic Zoneline operation.
No common busing is permitted. A separate wire
pair must be run from each separate controlling
switch to each individual Zoneline.
Room Air Sensor (Requires room air sensor kit – RAVRMS)
When connected, the room air sensor will allow
utilization of the temperature limiting and freeze
sentinel features.
NOTE: If GE thermostat RAK148D1, RAK148P1
or RAK164D1, RAK164P1 is used with the unit,
the room sensor kit is not needed for temperature
limiting since this feature is incorporated in the
thermostats.

IMPORTANT:
The Zoneline thermostat connections
provide 24V AC only.
If using a digital/electronic wall thermostat,
you must set it to the 24V AC setting. See the
Installation Instructions for the wall thermostat.
CAUTION:
Damage to a wall thermostat or to the
Zoneline electronics can result from improper
connections. Exercise extra attention when
connecting blue and black wires. No line
voltage connections should be made to any circuit
in the thermostat. Isolate all wires in building from
line voltage. 7

Door Sensor (Obtained locally)
The Occupancy Sensor dip switch must be
in the up position to use this feature.
When connected, the door sensor will detect
when the door in the room is opened or closed.
This feature must be used in conjunction with
the motion sensor.
The door and motion sensors work together
to automatically cycle the unit between normal
and energy management operations.
Central Desk Control
When connected, the unit lock-out is released
and it can be turned ON or OFF with a switch
located at the Central Desk Control. A separate
wire pair must be run from each separate
controlling switch to each individual Zoneline.
Motion Sensor (Obtained locally)
The Occupancy Sensor dip switch must be in
the up position to use this feature.
When connected, the wall mounted motion sensor
will detect motion in the room and automatically
cycle the unit between normal operation and

The ventilation control lever is located on the left
side of the Zoneline unit, behind the front case
panel.
To access the ventilation control lever, remove
the front panel by removing the filter, taking out
the four front screws, the upper two screws from
the top of the panel and the shipping screws on
each side, if present. (Discard the two side shipping
screws, if present).
When the lever is in the CLOSE position, only the air
inside the room is circulated and filtered.
When the lever is in the OPEN position, some
outdoor air will be drawn into the room. This
will reduce the heating or cooling efficiency.
To close the vent, push the vent lever handle
down, pull it forward and lock it up in place.
To open the vent, push the vent lever handle
down, push it back and lock it up in place.
Energy Tip: Keep the vent control in the CLOSE
position. The room air will be filtered and circulated.

Other features of your Zoneline.
About Heat Pumps (on some models)
Heat pumps can reduce operating costs by
exchanging heat from the outside air—even
when the outside temperature is below freezing—
and releasing that heat indoors.
To get the best economic benefit from your heat
pump, don’t change the room thermostat setting
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.

Do Not Operate Cool-Only Models in Freezing Outdoor Conditions
Cool-only air conditioners are not designed
for use when freezing outdoor conditions exist.
They must not be used in freezing outdoor
conditions.

Indoor/Outdoor Coils
The exhaust coils on the Zoneline should be
checked regularly. If they are clogged with dirt
or soot, they may be professionally steam cleaned
by your GE service center. You will need to remove
the unit from the case to inspect the coils because
the dirt build-up occurs on the exhaust side.

Care and cleaning. ge.com
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 “gel-like”
substance may be present in the base pan.
Check it periodically and clean, if necessary.
Turn off the Zoneline and disconnect the power supply before cleaning.
Outdoor coils
To maintain optimum performance, change the filter at least every 30 days.
Air Filters
The most important thing you can do to maintain
the Zoneline is to change the filter at least every
30 days. Dirty filters reduce cooling, heating
and air flow.
Changing the filter will: Decrease cost of
operation, save energy, prevent clogged heat
exchanger coils and reduce the risk of premature
component failure.
CAUTION: Do not operate
the Zoneline without the filter in place. If a filter
becomes torn or damaged, it should be replaced
immediately.
Operating without the filter in place or with
a damaged filter will allow dirt and dust to reach
the indoor coil and reduce the cooling, heating,
airflow and efficiency of the unit.
Replacement filters should be purchased
from your local retailer where air conditioner
and furnace accessories are sold.
Filter size required is 20″x 20″x 1″.
Have the coils cleaned regularly.
