Unit also meets ASTM E331-86 (Hurricane Test) which
specifies no water can enter through the unit during 15
minute exposure to rainfall at the rate of eight inches per
hour with 63 mile per hour wind velocity.
• Ventilation Control
Hidden controls help prevent unauthorized selection of outdoor
air ventilation - Saves energy
Zoneline chassis are capable of introducing up to 70 CFM of
fresh air into a room. This feature allows maintenance
personnel to “freshen” a room and reduce odors caused by
stale indoor air.
The vent door control is located on the left side of the
chassis behind the room cabinet and out of sight of the
room occupant. Hiding the vent control from the room
occupant ensures that it cannot be changed from the
condition desired by the building management. This is
important because an open vent door introduces
unconditioned air into the room. The additional heat load
causes the unit to operate longer and that translates into
higher operating costs! In warm humid climates the
introduction of outdoor air
may allow excessive
moisture (water vapor) to
enter the room. If the room
air reaches a humidity level
above the “Dew Point” of
the cold discharge air, the
moisture in the room air
will condense into visible
droplets. This condition is
often referred to as “the
unit is producing “Fog, or Fogging.”
• Easy Access Air Filters
Two up-front filters are removable from top of unit without
removing room cabinet
A clean filter is essential for good air conditioner
performance and longer life.  A dirty filter reduces air flow
which results in higher energy consumption. GE has made
filter cleaning an easy task! Some packaged terminal air
conditioners or heat pumps which require removal of the
room cabinet or a “blind positioning” of the filter under the
unit, the up-front filters on the GE Zoneline are conveniently
accessed by simply pulling them up from the top of the room
cabinet. This feature reduces maintenance time and helps
keep the units operating in peak condition. Because the
filters are so easy to
remove, it also
increases the
likelihood that
cleaning will occur
on schedule.
Chassis Features and Benefits
• Automatic Frost Control
Permits unit to be operated in cooling mode with low outdoor
temperatures
Occasionally, cool outdoor temperatures and high indoor
humidity conditions will cause frost to form on an air
conditioner’s indoor coil. When this occurs, the excessive
frost restricts air flow and decreases cooling performance.
GE Zoneline’s Automatic Frost Control detects when frost is
forming and shuts off the compressor to prevent component
damage. The
unit restarts
automatically
when the frost
has melted. This
feature enables a
room occupant to
select cooling in
spite of low outdoor
temperatures.
• Weather Protected Electrical Components
Extends life of electrical components
Outdoor conditions may shorten the life expectancy of
electrical components such as capacitors and relays. To the
extent possible, all electrical components are located on the
indoor side of the weather barrier (the sheet metal
component separating the indoor side and the outdoor side
of the unit) to protect them from the outdoor elements.
• Corrosion Treatment (Optional)
Helps extend the life of the unit in corrosive environments
An air conditioner installed close to a seacoast or highly
corrosive industrial environment, where acids or salts are in
the atmosphere, will not have the life expectancy of a unit
installed elsewhere. To help extend the life of a Zoneline
installed in these areas, steps are taken to make the unit less
susceptible to corrosion. For example, selection of non-
corroding materials, a process of protecting metal parts by
galvanizing and an electro-deposited paint system, all help
retard corrosion. In addition, the aluminum fins on the
outdoor coil are specially treated to extend their
operating life. (Standard on Dry Air 25 Models)
All GE Zonelines can be ordered corrosion treated except
3200 Series Heat Pump units with Internal Condensate
Removal (ICR) System, 265V 2KW Heater Models, 5200
Series Heat Pumps or 2200 & 3200 Series 5KW Heater
Models. Never install a unit with ICR in a seacoast or
corrosive environment. Units installed in corrosive
environments should be examined and cleaned regularly.
• Weather-Resistant “Superseal”
Minimizes air and water infiltration through the unit
When the GE Zoneline is properly installed in an
undistorted GE Zoneline wall case, the air infiltration
through a unit without ICR is a maximum of seven cubic
feet per minute with a 25 mile per hour wind velocity. Units
with ICR have a maximum of ten cubic feet per minute with
the same conditions. The air infiltration test is conducted in
accordance with ASTM E283-91. The ARI specification for
air infiltration for a unit the physical size of the Zoneline is
19 cubic feet per minute.
