Condensate Disposal Systems; Reversing Valve - GE Zoneline 6100 Series Technical Service Manual

Reversing Valve

The reversing valve operates on 230/208 VAC or
265 VAC, and is used to switch the direction of
refrigerant fl ow. The reversing valve controls the
direction of the refrigerant fl ow.
When the reversing valve solenoid is energized,
it will move the reversing valve, and the unit will
operate as an air conditioner. When the solenoid is
de-energized, the reversing valve will move in the
opposite direction, and the unit will function as a
heat pump.
To check the reversing valve solenoid, disconnect
the reversing valve wire harness on the driver board
at location CN105. Check for a resistance of less
than 1 Ω on the disconnected wires.

Condensate Disposal Systems

Slinger Ring Systems
Packaged terminal units employ various means
of dispersing the condensate water against the
outdoor coil. One of the most popular and most
effective means is the use of a slinger ring. A
slinger ring is a ring around the circumference of
the outdoor fan. The design of the unit positions
the slinger ring very close to the bottom of the
base pan, so water in the base pan is lifted by the
rotating ring. Water picked up by the slinger ring will
be dispersed into the airstream and deposited on
the hot outdoor coil where it evaporates.
All Zoneline Series packaged terminal air
conditioners and packaged terminal heat pumps
utilize a slinger ring for cooling condensate disposal.
Drain Kit
Although the Zoneline units are designed to
dissipate most of the condensate generated
during normal cooling operation, there may be
times when abnormal operating conditions cause
more condensate than the unit can dissipate.
If condensate dripping from the wall case is
objectionable, an external drain system, such
as Part # RAD10, should be installed. See the
Installation Instructions for the drain kit.
ICR Pump
During heat pump operation, the ICR system utilizes
a small pump to lift the water from the base pan
and pump it into a collector tray positioned above
the indoor coil.
The water drains from the collector tray and drips
onto the warm indoor coil where it is evaporated
into the room atmosphere. If an excess amount of
water is pumped to the indoor side, it is routed back
to the outdoor portion of the base pan.
The ICR system has proven to be an effective means
of minimizing the amount of heat pump condensate
dripping from the unit. However, if the restrictions
of a particular installation will allow absolutely no
dripping of condensate water from the wall case,
the installation of an external drain system is
recommended.
