FEATURES & BENEFITS
STANDARD PHYSICAL DIMENSIONS
GE Appliances has maintained the same wall sleeve
dimensions since 1961—42" wide x 16" high x 13-3/4"
deep—making replacement of older units easy.
WEATHER RESISTANT SYSTEM SEAL
Per AHRI, the air infiltration rate shall not exceed 19.3 CFM
at the perimeter of the wall sleeve where it normally
projects through the wall.
With superior design and premium materials, a properly
installed Zoneline unit in an undistorted sleeve keeps air
leakage to a minimum (5 CFM).
COMPOSITE BASE PAN
The base pan is made of SMC and comes standard on all
models. Since the base pan is exposed to the elements
and is a water bearing device, this composite (non-metal)
base pan eliminates the concern or problem of rusting
metal base pans.
HEATER SIZES TO MEET ROOM REQUIREMENTS
All units are equipped with a universal heater—
the resistance heat output is determined by power
connection kit.
230/208 Volt Units
15 AMP Circuits—2.4/1.96 KW—RAK315P and RAK315D
20 AMP Circuits—3.4/2.78 KW—RAK320P and RAK320D
30 AMP Circuits—4.8/3.93 KW—RAK330P and RAK330D
265 Volts Units
15 AMP Circuits—2.4 KW—RAK515D
20 AMP Circuits—3.4 KW—RAK520D
30 AMP Circuits—4.8 KW—RAK530D
UNIT CONTROLS
AZ45 and AZ65 Series—touch pad controls with large,
white LED readout with auto dimming feature, eliminates
the need for the control cover.
HIGHLY FEATURED MICROPROCESSOR CONTROLS
Microprocessor controls are programmed to interface with
the temperature sensors to maximize comfort conditions
or the room occupant and provide outstanding
performance features.
Thermistors are used to sense small changes in temperature
to give excellent room control and allow the microprocessor
to monitor and react to changing conditions.
ELECTRIC RESISTANCE HEAT LOCK-OUT
To maximize the savings of the heat pump operation, the
Zoneline
®
heat pumps do not utilize the resistance heater
when the outdoor temperature is above 46°F (and below
85°F) during normal operation. However, the resistance
heat is still used in the quick heat recovery feature.
AUTOMATIC EMERGENCY HEAT
Automatically uses electric resistance heat if the heat
pump output is not sufficient to maintain selected
room temperature.
REVERSE-CYCLE HEAT PUMP DEFROST SYSTEM
• Standard on all Zoneline AZ65 Series heat pumps
• Enables heat pump to operate at lower temperatures
when other systems switch to more expensive electric
resistance heat.
See pages 20–21 for discussion of heat pump operation
and defrost systems.
HIGH-TEMPERATURE HEAT PUMP OPERATION
PROTECTION
• Automatically protects the compressor if heat pump
is operated with high outdoor temperatures.
• Power to the outdoor fan is turned off if the indoor coil
gets too hot during heat pump operation to prevent
damage to the compressor.
QUICK HEAT RECOVERY—HEAT PUMP UNITS
When the unit operation is changed from OFF or COOL
to HEAT, the electric resistance heaters are used to warm
the room to the thermostat set point for the first cycle.
This provides faster room temperature increase for
greater guest comfort.
FAN MOTORS—PERMANENTLY LUBRICATED
• All units have two fan motors for quiet operation
and maximum operating efficiency.
• Motors are permanently lubricated to reduce
maintenance and totally enclosed to keep dirt and
water out of the motor windings.
OUTDOOR FAN
The unit automatically selects the most efficient speed
for the outdoor fan. The operating sound level is lower
when the outdoor fan can operate in low speed, yet
there are situations where it must operate in high
speed. The unit changes the fan speed automatically.
INDOOR FAN SPEED SELECTIONS—HIGH/LOW
Unit may be operated in HIGH HEAT, LOW HEAT,
HIGH COOL or LOW COOL. The unit also provides
the option of selecting either HIGH or LOW speed for
Fan-Only operation.
FAN-CYCLE SWITCH— “SMARTFAN”
• Unique “SmartFan” allows the unit to operate the
indoor fan continuously in cooling operation and in
cycle mode for heating, to provide better guest
comfort. Smart Fan provides air circulation in summer
for its help in cooling and eliminates complaint of
cold-air draft during the heating season.
• Eliminates the need for changing fan-cycle
switch seasonally.
• “SmartFan” settings are controlled via the auxiliary
control setting push button.
