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.
