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.
