FEATURES & BENEFITS
TWO-SPEED INDOOR FAN MOTOR
FOR SELECTABLE HIGH AND LOW SPEEDS
Since the Zoneline Vertical chassis discharge air may be
routed through duct work for air distribution into one or
more rooms, the units are equipped with a two-speed fan
that provides greater air movement to compensate for
the additional duct length. GE Appliances recommends
an HVAC engineer be consulted to determine the best
fan speed for the application.
Higher CFMs tend to increase the operating sound level,
both from fan noise and from the air noise in the duct.
Higher CFMs also reduce the dehumidification rate of
the unit, while lower CFMs provide quieter operation
and better dehumidification. However, if the CFMs are
not high enough to adequately move the air through
the duct system, the unit will not be able to provide
a comfortable room.
If the Zoneline Vertical chassis is connected to a wall
thermostat without the ability to provide two fan speeds,
the fan speed will be determined by connecting the wire
controlling the fan to the low speed fan terminal or the
high speed fan terminal on the unit.
CORROSION PROTECTION
TREATMENT—STANDARD
All Z oneline Vertical chassis are protected
against damage from seacoast area
corrosion. Components that are in contact
with the salt air have special coatings or
are made of non-corroding materials to
help withstand the corrosive effects of the
environment. This protection includes the use
of totally enclosed outdoor fan motors with painted casings
and a special coating on the outdoor coil to extend the life
of the unit in a coastal environment. The base pan is made
of durable non-corrosive plastic.
SLINGER RING CONDENSATE REMOVAL
Condensate water removed from the indoor air is
dispersed into the air stream by the outdoor fan slinger
ring and deposited on the hot outdoor coil. The water
helps cool the refrigerant in the outdoor coil and
increases the efficiency of the air conditioner, while
reducing the condensate draining from the unit.
INDOOR COIL FROST CONTROL
Under certain operating conditions, frost can form on
the indoor coil of an air conditioner, reducing air flow
and cooling. In order to prevent frost from forming, the
Zoneline Vertical chassis has an automatic frost control
on the indoor coil. When frost begins to form on the
coil, the compressor stops while the indoor fan continues
to run, until the coil temperature increases and the
frost dissipates.
At that time, the compressor resumes operation and
cooling continues. The indoor fan remains running
during the time the compressor is off to help warm
the coil with room-temperature air.
AUTOMATIC COMPRESSOR RANDOM RESTART
In the event of a power interruption, all compressors
attempting to restart immediately when power is
restored can result in a power surge that can cause
another power failure. The microprocessor in the
Zoneline Vertical chassishas a random restart logic
system that prevents all compressors from restarting
at the same instant.
COMPRESSOR RESTART DELAY
Zoneline Vertical units are designed to provide
a minimum of three minutes of compressor off time
to allow refrigerant pressures to equalize before
attempting to restart. Attempting to restart against
a high head pressure shortens compressor and
overload protector life.
The units are also designed to provide a minimum
of three minutes of compressor run time to prevent
short cycling from disturbing the room occupant.
FREEZE SENTINEL
• Detects low room temperature and turns heater on
to help protect against damage caused by freezing
room temperatures.
• The electric heater turns on at 41
o
F and warms the
room up to 46
o
F and shuts off.
• Freeze Sentinel may by turned off via the
auxiliary control.
HEAT SENTINEL
The property owner may choose to activate the
Heat Sentinel feature on the Zoneline unit. If the Heat
Sentinel is activated and room temperature reaches 85
o
F (even when the unit is in the “OFF” mode), the unit will
automatically start the air conditioning operation and
will shut off when the room temperature reaches 80
o
F.
This will help dehumidify the air and lower high
temperatures so the guest will not be entering an
extremely hot room.
