PROTECT YOURSELF AND OTHERS BY OBSERVING ALL SAFETY INFORMATION. FAILURE TO COMPLY WITH INSTRUCTIONS
COULD RESULT IN PERSONAL INJURY AND/OR PROPERTY DAMAGE!
RETAIN INSTRUCTIONS FOR FUTURE REFERENCE.
Air curtains produce a wall of continuously flowing air
that acts as a thermal barrier against outside air and
provides protection against insects, dust, odor, fumes
and other contaminant’s. Maintains interior conditioned
temperature by preventing heated or cooled air from
escaping through open doorways.
Heated air curtains are engineered to treat incoming
cold air at customers’ entrance areas. Used over front
door entrances, heated air curtains supplement existing
heat to prevent infiltration of colder outside air. Heated
units are not recommended for areas subject to high
winds.

5. Carefully disconnect motor electric cord and heater
plug assembly and remove two wing nuts on blower
base. (See Figure 4.)
Figure 4 - Removing Motor/Blower Assembly
NOTE: Unit is shipped with styrofoam motor support
block which must be discarded at this time.
6. T o remove motor/blower assembly, lift from rear of
motor housing to prevent damage and mis-alignment
to shaft and blower wheels.
NOTE: After unpacking unit, inspect carefully for any
damage that may have occurred during transit.
Check for loose, missing or damaged parts.
6. All wiring should be done by a qualified electrician,
using copper wire only and in accordance with the
National Electrical Code (NEC), all applicable code
and ordinances, and all sections of this manual. Any
variance voids the warranty and may create unsafe
conditions.
7. Special attention must be given to any grounding
information pertaining to this product. To prevent the
risk of electrocution, the unit must be securely
and adequately grounded. This should be
accomplished by connecting a
grounded conductor between the service
panel and the grounding lug or green leadwire
provided in the wiring compartment. To ensure a
proper ground, the grounding means must be tested
by a qualified electrician.
8. Do not insert fingers or foreign objects into the air
curtain. Do not block or tamper with it in any manner
while it is in operation. Do not touch it while in operation or just after it has been turned off, as some parts
may be hot enough to cause injury.
9. This product must NOT be used in potentially danger-
ous locations such as flammable, explosive chemical
laden, or wet atmospheres.
10.Do not attach ductwork to this product or attempt to
use it as a make-up air heater. Such use voids the
warranty and may create unsafe conditions.
WARNING: TO REDUCE THE RISK OF FIRE OR
ELECTRIC SHOCK, DO NOT USE THIS AIR CURTAIN
WITH ANY SOLID STATE SPEED CONTROL DEVICE.
1. With packaged unit on the floor, carton arrows should
point upward.
2. Carefully remove staples from top of carton and fold
back sides.
3. Carefully remove cabinet from carton by lifting out
unit using finger holes in styrofoam side inset and
place on work surface.
CAUTION:Do not attempt to lift this air curtain by its
louver or damage may result.
4. Unscrew six (6) knurled nuts and remove air intake
grille. (See Figure 3.)
Figure 3 - Removing Air Intake Grille
WARNING - TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS OBSERVE
THE FOLLOWING:
1. Use this unit only in the manner intended by the manufacturer. If you have questions contact the manufacturer.
2. Before servicing or cleaning unit, switch power off at
service panel and lock service panel to prevent power
from being switched on accidentally .
3. Installation work and electrical wiring must be done by
qualified persons in accordance with all applicable
codes and standards, including fire rated construction.
4. When cutting or drilling into wall or ceiling, do not
damage electrical wiring or other hidden utilities.
5. Make certain that the power source conforms to the
electrical requirements of the unit. Disconnect power
before installing or servicing. If the power disconnect
is out of sight, lock it in the open position and tag it to
prevent unexpected application of power. Failure to do
so could result in fatal electrical shock.
WARNING: DO NOT DEPEND UPON A THERMOSTAT
OR OTHER SWITCH AS THE SOLE MEANS OF
DISCONNECTING POWER WHEN INSTALLING OR
SERVICING THE UNIT. ALWAYS DISCONNECT
POWER AT THE MAIN CIRCUIT BREAKER AS
DESCRIBED ABOVE. FAILURE TO DO SO COULD
RESULT IN FATAL ELECTRIC SHOCK.

FIELD POWER WIRING
WARNING: ALL AIR CURTAINS SHOULD BE
INSTALLED BY QUALIFIED PERSONNEL.
1. Before wiring be sure that available power supply,
voltage, phase and frequency corresponds to that
specified on heater rating plate. In addition, make
certain that service capacity is sufficient to handle load
imposed by the equipment.
2. Install all wiring, protection and grounding in accordance with the National Electrical Code (NEC) and
all local requirements.
WARNING: THIS FAN HAS AN INTERNAL SELF
RESETTING THERMAL OVERLOAD PROTECTOR.
ALWAYS DISCONNECT FROM POWER SUPPLY
BEFORE SERVICING.
3. Run proper size copper power supply conductors from
the field power supply disconnects, (supplied by
others) with insulation rated minimum 75°C (167.0°F).
One set of conductors from 208VAC, 50/60Hz supply
source shall be routed through the 3/4 inch conduit
knockout, using a suitable knockout connected to the
contactor contact terminals marked L1, L2, L3.
4. The heater control box must have an unbroken
electrical ground to minimize personal injury if an
electrical fault should occur.
FIELD CONTROL
WIRING
Electric heater is equipped with a step-down transformer
for 24V control circuit. Thermostat model number RSV130-R-54 must be used to energize heater with the fan
motor. Connect thermostat wiring from thermostat to
control leads in heated air curtain control box by means
of conduit or equivalent. A 1/2 inch knockout is provided.
Class 1 wiring is required.
5. Replace heater control box cover.
6. Unit is ready for operation.
7. Restore power.
NOTE: Air curtain has high/low selector switch. See
Operation section for proper setting instructions.
8. Upon completion of all installation, inspect unit for
excessive vibration during operation. If excessive
vibration is noticeable, disconnect power supply.
Inspect mounting installation and refer to
Troubleshooting Chart for probable cause.
