E-RDE16-41 Duct Enclosure for
REMD16-41 and REMD16M-41
Economizer Limited Application
GCS16H Series Units Only
GCS16H may be converted to downflow operation by add
ing an RDE16-41 downturn transition and RMF16-41 roof
mounting frame as shown in figure 56. A manual outdoor
air damper is factory provided with the RDE16. The damp
er is located in the access panel covering the economizer
opening. The damper provides a field set amount of out
door air exchange (0 to 25%) at all times.
REMD16-41 (or REMD16M-41) economizer may be used
with GCS16H units in a limited downflow only application.
However, neither economizer can be directly mounted to
GCS16H. The RDE16-41 duct enclosure must be used to
provide the proper opening for economizer. Duct enclo
sure RDE16-41 mounts to the GCS16H horizontal air
openings and the economizer slides in the RDE16-41
economizer opening (see figure 57 for installation).
The GCS16H is not factory equipped with the necessary
wiring needed to connect an REMD16-41 or
REMD16M-41. To compensate for the lack of unit har
ness, an economizer harness is provided in the
RDE16-41. The economizer connects to the RDE16-41
harness using jackplugs. The RDE16-41 uses pigtails to
hard-wire the economizer harness to the unit. Field wire
routing is shown in figure 58. Field wiring is shown in figure
59.
