GE PDW9880J manual Deluxe models, Special corrosion-protected units, Internal condensate removal

Deluxe models

2900 series and Dry Air 25 series – heat/cool units 3900 series – heat pump unit

Highly featured microcomputer controls

Central desk control compatible

Ability to turn the unit “on” or "off" from a remote location.

Two fan motors (not visible) Separate motors for indoor and outdoor fans to assure quiet operation.

Reversible louver (not shown)

May be reversed to provide an air discharge angle of 40 or 50 degrees off vertical with the simple removal of six screws.

3-Position vent control (not shown)

Opens vent. Provides up to 75 cfm of outdoor air. The closed position saves energy by recirculating conditioned room air.

Reverse cycle defrost (not shown) Solid-state sensor monitors frost build-up on outdoor coil. When frost is detected, the refrigerant flow is reversed to melt frost build-up. When completed, the refrigerant is reversed to the normal energy-saving heat pump operation for additional heat pump operating hours.

Easy-access filter (not shown)

Two upfront interchangeable filters are part of roomside cabinet for easy access and maintenance.

Remote control compatible

Ability to be controlled by a wall-mounted thermostat with high or low fan speed.

Solid-state thermostat control Provides better room temperature control vs. electromechanical temperature control device.

Freeze Sentinel™ Provides automatic protection against freezing by switching the unit to heat should the temperature of an unoccupied room drop to 41°F.

Heat Sentinel Provides automatic protection against overheating by switching on the unit to cool should the temperature of

an unoccupied room reach 85°F.

Auto frost control

A special sensor monitors the roomside coil to prevent efficiency-robbing accumulation of frost during cooling operation.

GE Dry Air 25 (not shown)

Innovative technology from Heat Pipe Technology, Inc enables the DryAir 25 to remove 25% more moisture from the air than standard GE packaged terminal air conditioners.

Electronic temperature limiting Preset cooling and heating limits with 7 independent cooling and 7 heating limits—saves energy by preventing over-cooling or over-heating of rooms.

“Smartfan”

fan cycle selection Select fan cycle or fan continuous independently for heating and cooling.

Universal power cord Flexibility of heat applications. All Zonelines contain a bank of 3 heaters.

Rotary compressor Fewer moving parts than reciprocating models for quiet, reliable operation and longer life.

Touch pad controls With electronic control temperature display. Gives the user finer control over the temperature.

The Dry Air 25

The Dry Air 25 features innovative technology from Heat Pipe Technology, Inc., an addition which enables this unit to remove 25% more moisture from the air than standard GE Zoneline® models. The Dry Air 25 system, Heat Pipe, is a hermetically sealed heat transfer surface that is saddlebagged around the indoor coil (evaporator) of the Zoneline. This coil arrangement will transfer heat from one coil to another without power consumption. This assembly uses R-22 as the refrigerant and is isolated from the regular Zoneline refrigerant circuit.

As warm humid air is pulled through the pre-cool section of the Heat Pipe, the heat removed from the air is absorbed by the refrigerant, causing the refrigerant to boil. As the pre-cooled air passes through the Zoneline evaporator, the air is further cooled (colder than it would be normally), removing 25% more moisture from the air than standard GE packaged terminal air conditioners.

As the cold air passes through the reheat section of the Heat Pipe, the refrigerant condenses and the liquid flows back to the pre-cool section to be reheated again. The air discharged into the room by this process is much drier, creating a more comfortable room condition.

Special corrosion-protected units

To help extend the life of the Zoneline unit in seacoast areas, some Deluxe Zoneline units may be ordered with a special corrosion protection treatment on outdoor components and use stainless steel hardware. Zoneline units with optional corrosion protection have a ‘C’ in the 10th character of the model number.

Internal condensate removal

Available on the 3900 and 5800 heat pumps, this feature drips the heat pump condensate over the warm indoor coil to help dissipate water from heat pump operation and associated defrost cycles. The installation of an internal or external drain system is recommended if no dripping of condensate to the outdoors is desired. ICR must not be installed in seacoast or corrosive applications.
