The architectural design of a building may dictate the
use of special or oversized louvers for aesthetic reasons.
Louvers other than standard Zoneline
®
exterior grilles
may be used on the Zoneline unit, however, these special
louvers, or any special exterior architectural treatments
of the building facade that may restrict the free
circulation of condenser airflow, should be referred to
GE Appliances Application Engineering for evaluation
and approval. The following guidelines should be
followed in selecting a louver:
1. The louver must have a minimum of 65% free area.
ASHRAE defines "free area" as the minimum area of
the opening in an air inlet or outlet through which air
can pass. Percent (%) free area equals the X dimension
divided by the Y dimension.
2. The louver should be attached to the wall sleeve in a
manner that will prevent recirculation of condenser
discharge air into the air inlet. If the louver is not
attached directly to the wall sleeve, a field-supplied
splitter or gasket is required between the chassis and
the louver to prevent recirculation.
It is important that the above criteria be followed since
a louver that is too restrictive or allows recirculation will
reduce the unit’s capacity and efficiency, increase the
electrical current draw, cause intermittent operation
All AZ45 and AZ65 Series Zoneline units are equipped
with universal heaters allowing chassis installation
flexibility. The Zoneline units are connected to the
building power supply by a unique power connection
kit. By utilizing a separate universal power connection
kit, each unit is capable of providing various outputs of
electric resistance heat to more closely meet the heating
requirements of the particular room, thereby increasing
the installation flexibility of the particular chassis. This
power connection kit is the only means of supplying
power to the Zoneline chassis.
The appropriate kit is determined by the voltage, the
means of electrical connection, either line-cord
connected or permanently connected, and the desired
resistance heat output that may be supported by the
branch circuit.
230/208 VOLT
LINE CORD
CONNECTED UNITS
Line Cord Kits consist
of a self-aligning
four-pin molded
connector that
plugs into a mating
connector on the
Zoneline chassis
and insulated line
cord with an
electrical plug
on the end.
FOUR PIN CONNECTOR
AND 20 AMP PERSONALITY PLUG
The configuration of the electrical plug conforms to Nation
Electrical Code (NEC) standards for the circuit amperage,
and the configuration of the extra personality plug
determines the heater wattage and current requirements
when it is plugged into the Zoneline chassis. If the four pin
connector does not have a personality plug (or the plug is
not connected) the unit identifies it as a 15 amp circuit.
The power connection kit is selected by the amperage of
the circuit where it will be installed. Each line cord kit has
an integral Leakage Current Detection Interrupter (LCDI)
or Arc Fault Current Interrupter (AFCI) device as required
by the NEC and Underwriters Laboratory (UL) for line-cord
connected air conditioners manufactured on or after August
1, 2004. The line-cord power connection kits are shown in
the table below.
due to the compressor overload protector shutting the
compressor off, and cause failure of the compressor
overload protector and shorten compressor life. Using
the unit with a grille that is too restrictive or allows
recirculation may constitute improper installation and
will void the unit's warranty.
A scale drawing of the louver section should be sent
to GE Appliances Application Engineering. To assure
the proper performance of the Zoneline unit and comply
with Underwriters Laboratories
®
requirements, it may be
necessary to send a sample louver section (at least 16" x
42") to an independent lab to be tested with the
Zoneline unit.
