Note: For multiple unit installations, recommended spacing between units should be a minimum of 3-inches and a maximum of 6-inches
Unit is allowed to extend beyond doorway width Each unit must have individual power supply
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 and 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

Note that all dimensions are the same on all environmental
series units Model number indicates width of unit

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 To 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 opera-
tion 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 )
WARNING - TO REDUCE THE RISK OF FIRE, ELEC-
TRIC SHOCK, OR INJURY TO PERSONS OBSERVE
THE FOLLOWING:
1 Use this unit only in the manner intended by the man-
ufacturer If you have questions contact the manufac-
turer
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.

Installation
1 Using template provided, determine mounting
location
2 Drill holes and attach mounting hardware (not
included)
IMPORTANT: THE HARDWARE AND THE
SUPPORTING STRUCTURE MUST BE CAPABLE OF
SUPPORTING A MINIMUM 150 LB. LOAD.
NOTE: All installation should be done to meet local
building code
3 Mount cabinet on wall and securely tighten hardware
4 Replace motor/blower assembly in cabinet Secure

refasten knurled nuts
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 cer-
tain that service capacity is sufficient to handle load
imposed by the equipment
2 Install all wiring, protection and grounding in accor-
dance 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 Remove two screws from switch box and remove
cover
4 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 240VAC, 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 A
separated set of supply conductors from a 120VAC,
50/60 Hz supply source shall be routed through 1/2
inch knockout using a suitable knockout connector, for
connection of the fan circuit The fan supply
conductors are to be marked L1, N (see diagram on
inside heater wiring compartment cover and Figure 5)
5 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 RSV-
130-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
Class1 wiring is required
6 Replace heater control box cover
7 Unit is ready for operation
8 Restore power
NOTE: Air curtain has high/low selector switch. See
Operation section for proper setting instructions.
9 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
Figure 5 - Wiring Diagram

Operation
1 After power has been connected to unit, fans will start
in either preset (high/low) speed selection
2 Air velocity is controlled by selection of high or low
speed indicator This feature allows the setting of air
velocity to individual desired performance and energy
efficiency
3 Air direction at outlet can be controlled by adjustable
vanes at the nozzle which compensates for possible
draft conditions
NOTE: Air direction settings shown in Figures 6 & 7.
NOTE: Cold air will try to escape near floor level.
Warm air will try to penetrate curtain near top of
doorway. Air flow can be controlled by direction of
nozzle louvers and by high/low settings.
4 For multiple unit applications (wide openings), mount
units a minimum of 3” apart to allow for proper air
intake and discharge
Maintenance
WARNING: ALL ELECTRIC POWER MUST BE
DISCONNECTED WHEN INSTALLING OR SERVICING
THIS EQUIPMENT. MORE THAN ONE DISCONNECT
SWITCH MAY BE REQUIRED TO REMOVE POWER
FROM THE UNIT.
