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.

•Primary Drain – Centerline of drain is
approximately 51⁄4″from left platform edge
and 81⁄2″from back platform edge.
•Secondary Drain – Centerline of drain
is approximately 61⁄2″from left platform edge
and 51⁄4″from back platform edge.
3. Place the platform in the utility closet
with the following clearance between it
and the interior surface of the walls/door/panel:
•4″min. from front of the case –
Unit to be installed through FRONT of case
•5″min. from front of the case –
Unit to be installed through SIDE of case
•3″min. from two sides of the case
4. Align the platform with the opening of
the wall plenum and secure to the floor
using appropriate brackets and bolts.

INSTALL THE DRAIN(S)
An external or an internal drain must be attached
to the primary drain connector. A secondary drain
is supplied if required by state and local codes. Refer
to the local codes for proper installation of the drains.
If the secondary drain is not used, seal its drain port
with a 3/4″MNPT plug.
External Drain
Attach a 90° PVC elbow to the unit’s female 3/4″NPT
drain connector. Use the other end of the elbow to run
a 3/4″Sch. 40 PVC pipe through the knockout holes of
both the wall plenum and the architectural louver to the
outside. Seal the gap between the plenum hole and PVC
tube. See the Installation Instructions in the RAVAL1.
Internal Drain
Attach PVC to the unit’s female 3/4″NPT drain
connector. See the Installation Instructions
in the RAVAL1. Local codes may apply.
2DUCTWORK
Prepare the closet ductwork for later connection
to the case.
The total flow rate (CFM) and external static pressure
(ESP) available can be estimated from the chart below.
Use these charts to select your fan speed setting. The
collar on top of the case accepts standard 10″duct.
Pull all duct tight. Extra duct slack can greatly increase
static pressure.
CAUTION: Flex duct can collapse and
cause airflow restrictions. Do not use flex duct for 90°
bends or unsupported runs of 5 ft. or more.

Installation Instructions
Your airflow should be balanced based on many factors,
such as available ESP, room CFM, and ductwork. Consult
an HVAC engineer for proper applications. External static
pressure (ESP) can be measured with a manometer or
pitot tube. Once this ESP is established, you can
calculate the CFM using the above chart.
CFM Recommendations
9,000 BTU 12,000 BTU 18,000 BTU
275 300 325 350 375 400 450 500 550
•••
• = Recommended Mid Range
Higher CFMs tend to increase Sensible capacity,
enhance room circulation and increase duct noise,
while lower CFMs tend to increase Latent capacity
and reduce noise.
