CONCEALED MANUAL VENT CONTROL
An open ventilation door on GE Appliances Zoneline
®
packaged terminal air conditioners and heat pumps allows
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, located along the left side of the
unit under the front cover, is used to open and close the
vent door.
NOTE: Two shipping screws must be removed from the
vent door before use.
The manual vent door has infinite adjustability with the slide
rod and wing nut to meet everyone’s needs. Simply tighten
the wing nut at the desired opening level. Positive vent door
closure and tightening of the wing nut prevents accidental
opening and unwanted air infiltration.
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.
For each CFM of air to enter the room, an equal amount
of air must be removed through exhaust fans in the
bathroom or rooftops. Greater amounts of air will be
introduced (from chart shown above) depending on the
size of the exhaust fan.
Zoneline vent openings are not intended to be the source
of make-up air for building ventilation systems since
the vent is not continuously conditioned or powered by
separate fans.

CORROSION PROTECTION (OPTIONAL)
AZ45 and AZ65 Series units may be ordered with
special protection to better withstand damage from
salt air and salt water in seacoast or other corrosive
areas.
Corrosion protection is standard on the
Dry Air and 265V models.
Makeup Air module units and heat pump units
with ICR are not available with corrosion protection
and should not be installed in seacoast or other
corrosive environments.
Units installed in corrosive areas should use the RAB77B
wall sleeve and be examined/cleaned more frequently
than normal installations.
INTERNAL CONDENSATE REMOVAL (ICR)
See page 36 for a discussion of the internal AZ65
Series heat pumps.
DRY AIR 25
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 AZ45 Series with the Dry Air 25 heat
pipe application removes 20–35% (varies by model)
more moisture than the standard AZ45 Series unit.
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.
See page 10 for more detailed information.
