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.

Operating Instructions Care and Cleaning Troubleshooting Tips Consumer Support

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.

2. Make drain hole cutout(s):

• Primary Drain – Centerline of drain is

approximately 5

⁄4″ from left platform edge

and 8

⁄2″ from back platform edge.

• Secondary Drain – Centerline of drain

is approximately 6

⁄2″ from left platform edge

and 5

⁄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.

DUCTWORK

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.
