•
BUILT-IN THERMOSTAT
APPLICATIONS
Auxiliary, supplementary or primary
heat source in factories, stores,
garages, basements, warehouses,
public buildings, service stations,
stockrooms, offices, workshops, toll
booths, closing offices, large or
exposed areas or additions.
FEATURES
HORIZONTAL AND
DOWN FLOW IN ONE UNIT
Heater is shipped with a ceiling mount
bracket that allows the heater to be
used in four indexed positions-straight
out (horizontal), straight down (down
flow), and two intermediate positions,
as well as any position in between. In
addition, louvers adjust up and down for
even greater control of throw direction.
Louvers have stops to prevent complete
closing of the discharge area. Heater
body also has top center hole with weld
nut for mounting the heater and
allowing it to pivot 360°. Wall mounting
bracket also available (see accessories
and controls).
EIGHT WATTAGES, TWO VOLTAGES
The HUH524TA & HUH724ST can be
connected to either 208VAC or 240VAC,
single phase service, and field-adjusted
to adapt the unit to four different
wattages for each voltage; e
BUILT-IN THERMOSTAT
Dial up or down for precise heating
comfort with single-pole built-in
thermostat. Temperature range 45°F to
135°F.
EASY TO INSTALL AND SERVICE
Remove one screw and bottom control
box cover swings down on hinges for
full access to controls and wiring.
Loosen four screws through keyhole
slots at the front of the heater for full
access to: heating element, fan delay
control and high limit cutout. Complete
access to the motor and fan is obtained
through the back by removing the four
screws holding the fan guard.
PLATE FIN ELEMENT
The heater provides uniform discharge
of all heated air with lower internal
operating temperatures and prolonged
element life-all due to the efficient
design of the plate fin element. Steel
fins are copper brazed to low watt
density, steel sheathed tubular heating
element. Fins and elements are
arranged in a uniform grid pattern and
are closely fitted into the air discharge
area to assure that all incoming air is
discharged through the heating
element.
SMOOTH, QUIET OPERATION
Motor is of unit bearing design with high
starting and running torques. Large,
dynamically balanced fan blades
provide maximum air flow, thus, heater
has minimum air turbulence and noise
in operation.
AUTOMATIC FAN CONTROL
All heaters are equipped with an
automatic fan delay control that delays
fan action until the heating element is
warm, and continues fan action until the
heating element has cooled after the
heating cycle. This action prevents
circulation of cold air and avoids
exposing the unit to residual heat, thus
providing higher comfort level and
prolonged component life.
THERMAL CUTOUT
A high limit thermal cutout automatically
shuts off the heater in the event of
overheating and reactivates it when
operating temperatures return to
normal.
