EVAPORATOR RETURN AIR PLENUM
Evaporator return air plenum is available for
installations where it is required to duct the
return air to the inlet of the evaporator. The
evaporator return air plenum allows the user
to connect round duct (flexible or rigid) to
the return air intake to reduce air noise and
increase the number of options for solving
difficult cooling problems. The plenum
attaches to the front of the unit, replacing
the return air grille.
2DEP-12 for OWC1811QC transitions the re-
turn opening to a 12-inch round duct.
NOTE—When a 2DEP-12 is installed,
it is recommended to set the evaporator
blower speed to high, to avoid evaporator
coil freeze-up
.

OWC1811QC ACCESSORIES
An optional discharge nozzle kit is used to direct the
conditioned air to a specific target area. By
concentrating the airflow, the nozzles increase the air
velocity towards production lines to cool personnel
and/or equipment. In server rooms, the nozzles can be
used to direct the airflow through the rack to remove
the heated air from the equipment.
2NK-2 for model OWC1811QC with (2) 6-inch diameter
nozzles with an approximate compressed length of 22".
The approximate extended length is 32".
The nozzle kit comes pre-assembled with the nozzles
secured to a mounting plate, and include edge guards.
By removing the OWC1811QC discharge grille, the nozzle
kit can then be installed in the grille opening.
