Glossary of Related Terms
Allen Wrench
5/32" tool used with hex fasteners on unit ventilator front access
panels and top access doors.
AE Unit Ventilator
The AE self-contained unit ventilator provides comfort cooling and
heating to the classroom, using an outside coil to reject the heat from
cooling. In the heat pump mode, the unit uses heat from the outdoor
air to heat the building interior. The unit also brings in fresh outdoor
air.

Condenser Coil
A coil for removing heat from refrigerant gas for the purpose of
causing the refrigerant gas to condense to a liquid.
“D” Seal
The horizontal gasket or seal on the wall sleeve cross channel that
positively contacts the unit outdoor section to help prevent air and
water leaks from entering the room.
Evaporator Coil
A coil in which a refrigerant gas is evaporated for the purpose of
extracting heat from the surrounding medium resulting in cooling of
the air passing over the coil.
Full Projection
The self-contained unit ventilator wall sleeve anchors to the interior
wall surface with no recess into the wall opening, requiring an
11-3/8" finish collar. The unit/wall sleeve combination projects a full
28 inches from the room wall.
Full Recess
The self-contained unit ventilator wall sleeve is fully recessed into
the wall opening, not requiring a finish collar, and the unit projects
into the room 16-5/8".
Grille
The grille is a decorative cover to the louver. The grille openings line
up with the louver openings to maximize the air flow.
Lintel
A horizontal beam across the top of a door, window, louver or wall
sleeve opening that supports the weight of the structure above it.

Louver
The louver is to bring in adequate amounts of outdoor air for the
outdoor fan section and ventilation air to the classroom while
providing a path for heated air in the outdoor section and to minimize
water entering.
MicroTech II™
Direct Digital Control system providing comfort and unit protection,
with Protocol Selectability™, allowing easy integration into existing
Building Automation Systems (BAS) using open, standard protocols.
N2 Open Standard Data Communication
A network communication protocol for building automation and
control networks.
Partial Recess
The self-contained unit ventilator wall sleeve is partially recessed
into the wall opening, requiring either a 3" or 5-1/4" finish collar.
Reciprocating Compressor
A compressor which raises pressure from a low to high pressure gas
by means of reciprocating pistons.
Remote Sensor
A remote wall mounted device that senses room air temperatures and
communicates with the unit ventilator.
Scroll Compressor
A scroll compressor uses an oscillating motion to raise the refrigerant
from a low pressure to a higher pressure.
Splitters
Horizontal Air Splitters function as partitions between the outdoor
discharge section, outdoor supply air section and the outside room air
section. They are required to provide proper air paths and prevent air
recirculation when there is a space between the wall sleeve and the
louver.
Wall Sleeve
The Wall Sleeve is used to secure the unit, provide a watertight and
airtight seal between the building and the unit. In addition, it brings
in electrical and control wiring (if required) and allows fast installa-
tion of the unit.
