The GE Zoneline
®
2900 and 3900 series are approved for
ducted installation using the GE Duct Adapter model RAK6052
and the GE Duct Extension RAK601. A field-fabricated duct
extension with the same interior measurements as the RAK601
may be used with the RAK6052 duct adapter. GE does not
recommend ducting in more than one direction.
The use of a duct adapter other than the RAK6052 is not
approved by GE and may cause problems such as inadequate
airflow to the secondary room or the unit shutting off on one
of the overload devices.
Failure to allow for adequate air return from the secondary
room is often the cause of less than satisfactory performance
of a ducted installation.
Replacement Installations
GE offers duct adapters to allow for easy replacements of
previous design chassis in ducted installations where a GE
duct adapter was used in the original installation. A duct
adapter is available that will align with the duct extension
when GE-built components were used in the original installation.
The duct extension used from the early 1960s until late 1987
was 8-3/8" high by 6-1/2" wide. If the chassis to be replaced is
the flat-top discharge (design until late 1987) the duct adapter
model RAK7012 will align with the existing duct extension.
This means the duct extension will not have to be changed.
However, to keep the cost of the replacement to a minimum
there are components that will need to be taken off the
existing installation and used on the RAK7012 duct adapter.
The wall case mounting brackets, screws, discharge grille,
damper, and end cap will need to be retained.
If the chassis is a slope-front discharge and the duct
dimensions are 8-3/8" high by 6-1/2" wide then the
chassis has already been replaced and the purchase
of a new duct adapter is not required. The only piece that
needs to be replaced in this installation is the transition
piece, model RAK7022, which fits between the chassis and
the duct adapter.
If the chassis being replaced has a model number that
begins with AZ22, AZ25, AZ28, AZ32, AZ35 or AZ38, the new
2900 or 3900 Series unit can be installed using the same
duct components.
If the existing chassis is a slope-front discharge and the duct
dimensions are 7-3/32" high by 6-1/2" wide only the RAK7022
transition piece is required to install a 2900 or 3900 Series
unit in the ducted installation.
There were a number of Zoneline units installed in ducted
installations that did not use a GE duct adapter. The easiest
way to determine if the existing duct adapter is a GE duct
adapter is to compare the duct adapter dimensions to the
dimensions above. If the dimensions are different than the
dimensions above or it the duct adapter is not made of sheet
metal, it is not a GE duct adapter. In such installations GE
recommends the removal of the old duct adapter and duct
extension and the installation of a RAK6052 duct adapter
and a RAK601 duct extension. Zoneline units installed in
installations not using GE duct adapters and an extension
with the same cross-section dimensions as the duct adapter
may not be covered by the warranty.
