IMPORTANT SAFETY INFORMATION.

READ ALL INSTRUCTIONS BEFORE USING.

A WARNING!

Riskof electric shock. Can cause injury or death. For your safety, the information in this manual
must be followed to minimize the risk of fire, electric shock or personal injury.

SAFETYPRECAUTIONS

[]

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.

[]

Replace immediately all electric service
cords that have become frayed or
otherwise damaged. A damaged power
supply cord must be replaced with
a new power supply cord obtained
from the manufacturer and not repaired.

Do not use a cord that shows cracks
or abrasion damage along its length

or at either the plug or connector end.

[]

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.
If you are getting rid of an old product

with refrigerants, check with the

company handling disposal about

what to do.

[]These R410A Air Conditioner Systems

require contractors and technicians to
use tools, equipment and safety standards
approved for use with this refrigerant.
DO NOT use equipment certified for R22
refrigerant only.

Central Desk Control

When connected, the unit lock-out is released
and it can be turned ONor OFFwith a switch

located at the Central DeskControl.A separate
wire pair must be run from each separate

controlling switch to each individual Zoneline. A
24VACcircuit powers the CDCsystem. Noexternal
power isrequired.

Remote Thermostat

Theunit will be controlled by u remote
thermostat.

IMPORTANT:

TheZoneline thermostat connections
provide 24V AConly.

If using a digital/electronic wall thermostat,

you must set it to the 24VACsetting. Seethe

Installation Instructions for the wall thermostat.

NOTICE:

Damage to a wall thermostat or to the
Zonelineelectronics can result from improper

connections. Exerciseextra 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.

When the leverisin the CLOSEposition,only the air

insidethe room iscirculated and filtered.
When the leverisin the OPENposition,some

outdoor air will be drawn into the room. This
will reduce the heating or cooling efficiency.

About Heet Pumps (onsome 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.

Toget the best economic benefit from your heat
pump, don't change the room thermostat setting

very often. Raisingthe heat setting 2-3 degrees
will cause the Zoneline to use its electric heating

elements in order to reachthe new temperature
setting quickly.

Do Not Operate the Air Conditioner (cool mode) in Freezing Outdoor Conditions

Air conditioners are not designed for usewhen
freezing outdoor conditions exist.Theymust not be

used in freezing outdoor conditions.

There isa 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 cyclesoff.

Theelectric heating elements use much

more electricity than heat pumps and cost
more to operate.

Care and cleaning. GEAppliances.com

Turn off the Zoneline and disconnect the power supply before cleaning.

Indoor/Outdoor Coils

Theexhaust coils on the Zonelineshould be
checked regularly. If they are clogged with dirt

or soot, they may be professionally steam cleaned
byyour GEservicecenter.Youwill need to remove

the unit from the case to inspectthe coils because
the dirt build-up occurs on the exhaust side.

-- Outdoor coils

Have the coils cleaned regularly.

Drain

Cleanthe drain system regularly to prevent
clogging.

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).

Air Filters

To maintain optimum performance, change the filter at least every 50 days.

Themost important thing you can do to maintain
the Zonelineisto change the filter at least every

30 days. Dirty filters reduce cooling, heating
and air flow.

Changing the filter will'.Decreasecost of
operation, saveenergy, prevent clogged heat

exchanger coils and reduce the risk of premature
component failure.

Insome areas of the United States,a "gel-like"

substance may be present in the base pan.
Checkit periodically and clean, if necessary.

Toremove
and replace

the filter:

NOTICE: Do notoperate

the Zoneline without the filter in place. Ifa filter
becomes torn or damaged, it should be replaced

immediately.

Operating without the filter inplace 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.
