Features And Benefits - Trane HUV Installation Operation & Maintenance

Configuration
The classroom unit ventilator is
available in both a
• horizontal (ceiling mount)
• vertical (floor mount)
configuration. The units range
from 750 cfm to 2000 cfm for the
horizontal configuration, and from
750 cfm to 1500 cfm for the vertical
configuration.
Cabinet
The units are constructed of 14-
and 16-gauge zinc coated steel. All
steel surfaces are cleaned, phos-
phatized, rinsed and dried before
application of final finish paint.
The paint is applied by an electro-
static powder spray system, mini-
mum thickness of 1.5 mil which
results in an appliance grade fin-
ish.
Front Panels
The front panels are retained by
Allen wrench operated tamper-
proof camlocks which open with a
180-degree rotation. The vertical
front panel is constructed of either
14 or 16 gauge material dependent
upon model option selected. See
Figure 1 for front panel with
camlock access.
End Pockets
The roomy 13 1/2-inch wide x 30-
inch high x 15 1/4-inch depth end
pockets provide easy field installa-
tion of valves, piping, and con-
trols. The units have a large pipe
access opening in both end pock-
ets and large knockouts for piping
and electrical connections. All
electrical connections are made in
the left-hand end pocket, with ex-
ception of units equipped with the
electric heating coil option. See
Figure 2 for end pocket sizing.

Features and
Benefits
Drain Pan
The drain pan is positively sloped
in all planes to assure proper
drainage and help eliminate the
risk of microbial growth. To help
ensure indoor air quality, the drain
pan is insulated on the bottom to
help prevent condensate forma-
tion. The drain pan can be easily
removed for cleaning purposes.
The drain pan is field reversible by
loosening 2-front screws and tilt-
ing.
A drain plug is located on each end
of the drain pan for the vertical
configuration. The plug is drilled-
out during assembly per model
number selection See Figure 2
for drain pan.
Fanboard
The fanboard assembly is acousti-
cally designed in a single, rigid as-
sembly that includes the fans, fan
housing, bearings, fan shaft and
motor. The fan motor is mounted
on the fanboard. The fanboard is
made from 14 gauge galvanized
steel to resist corrosion and in-
crease strength. The fanboard is
removed by extracting 2-screws.
115V Motor
The motor is a single speed per-
manent split capacitor with ther-
mal overload protection. A
multiple tap auto-transformer is
wired to the motor to provide dif-
ferent speed settings. The motor
speed is not affected by damper
positions. Standard motors are
rated up to 0.25 ESP. High static
motors are rated from 0.25 ESP to
0.45 ESP.
Motor bearings are permanently
lubricated. Isolation of the motor is
provided internally at the union
shaft. See Figure 3 for motor
disconnect.
