Features and Benefits
Up-Front Air Filters

up-front filters, easy
to remove and reinstall,
may be cleaned without
opening or removing
the room front.
Clean filters by brushing,
vacuuming or back-
flushing under faucet
or shower head.
Concealed Manual
Vent Control
Open ventilation doors on
GE Zoneline® Packaged
Terminal Air Conditioners
and Heat Pumps allow
outside air to enter the room through a screen-covered
opening in the weather barrier that separates the indoor
and outdoor sections of the unit.
A concealed lever is located along the left side of the unit
under the front cover is used to open and close the vent door.
The 3-position manual vent door control may be closed,
partially open or fully open. Positive vent door closure
prevents accidental opening and unwanted air infiltration.

CFM ratings at 230 and 265 volts.
For each CFM of air to enter the room, an equal amount of
air must be removed through exhaust fans in the bathroom
or roof tops. Greater amounts of air will be introduced (from
chart shown above) depending on the size of the exhaust fan.
Outside ambient air entering the room through this screened
vent opening is not conditioned. This unconditioned air
becomes mixed with the conditioned air that is circulated by
the indoor fan. This air mixture generates an additional heat
load/heat loss that causes the unit to run longer and may
translate into higher operating costs.
Zoneline vent openings are not intended to be the source
of make-up air for building ventilation systems due to the
additional heating or cooling loads generated.
Corrosion Protection (Optional)
4100 and 6100 Series units may be ordered with special
protection to better withstand damage from salt air and
salt water in seacoast areas.
Corrosion protection is standard on the Dry Air 25 models.
Heat pump units with ICR are not available with corrosion
protection and should not be installed in seacoast or
corrosive environments.
Units installed in corrosive areas should use the RAB77 wall
sleeve and be examined/cleaned more frequently than
normal installations.
Internal Condensate Removal (ICR)
See page 34 for a discussion of the Internal Condensate
Removal system available on 6100 Series heat pumps.
Enhanced Dehumidification
Moisture removal is an important function of an air
conditioner. People are more comfortable at higher
temperatures when the humidity level is relatively low.
Air conditioners operate with less energy consumption
when the room temperatures are set higher.
The GE Zoneline 4100 Series with the Dry Air 25 heat pipe
application removes 25% more moisture than the base
4100 Series unit.
The GE Zoneline Dry Air 25 chassis is the only PTAC available
with the application of the patented Dinh
®
Dehumidifier
Heat Pipe under license from Heat Pipe Technology, Inc.
Customers who are using the Dry Air 25 report a fresher-
smelling room as a result of the lower humidity levels, as
well as lower operating costs.
Locking Door Kit
RAK8023 — A door with a lock that replaces the standard
control cover door to prevent unauthorized changing of
control setting is offered as an accessory.
