FEATURES AND BENEFITS
Standard Physical Dimensions
GE has maintained the same dimensions since 1961 —
42" wide x 16" high x 13-3/4" deep — making
replacement of older units easy.
Weather-Protected Electrical Components
Vital electrical components are protected from the weather
by locating them on the indoor side of the weather barrier.
Weather-Resistant “Superseal”
Properly installed unit in undistorted case keeps air leakage
to a minimum.
7 CFM air infiltration with 25 MPH wind on ICR
units — even less on units without ICR
Industry specification is 19 CFM of air infiltration
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 — Line-Cord Connected Units —
2.4/2.32 KW with RAK3153A — 15-amp circuit
3.3/3.20 KW with RAK3203A — 20-amp circuit
4.7/4.53 KW with RAK3303A — 30-amp circuit
230/208-volt - Sub-Base Connected Units —
2.4/2.32 KW with RAK204D15P — 15-amp circuit
3.3/3.20 KW with RAK204D20P — 20-amp circuit
4.7/4.53 KW with RAK204D30P — 30-amp circuit
265-volt —
2.4 KW with RAK5172 — 15-amp circuit
3.4 KW with RAK5202 — 20-amp circuit
4.8 KW with RAK5302 — 30-amp circuit
Unit Controls
4100 and 6100 Series — touch pad controls with digital
readout of temperature set point
Highly Featured Microprocessor Controls
Microprocessor controls are programmed to interface with
the temperature sensors to maximize comfort conditions
for the room occupant and provide outstanding 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 during normal
operation. The resistance heat is 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 6100 Series heat pumps
Enables heat pump to operate at lower temperatures
when other systems switch to more expensive electric
resistance heat.
See pages 18 and 19 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 STOP or COOL to
HEAT, the electric resistance heaters are used to warm the
room to the thermostat set point. 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 or LOW HEAT or
HIGH COOL or LOW COOL.
