Description  
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.

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.  
 
Installation  
1. Using template provided, determine mounting loca-  
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.  
tion.  
2. Drill holes and attach mounting hardware (not includ-  
ed).  
IMPORTANT: THE HARDWARE AND THE SUPPORT-  
ING STRUCTURE MUST BE CAPABLE OF SUPPORT-  
ING 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  
two wing nuts on blower base. Reconnect motor  
electric cord plug assembly & heater plug.  
5. Replace intake grille with louvers facing down and  
refasten knurled nuts.  
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.  
Class 1 wiring is required.  
FIELD POWER WIRING  
WARNING: ALL AIR CURTAINS SHOULD BE  
INSTALLED BY QUALIFIED PERSONNEL.  
5. Replace heater control box cover.  
6. Unit is ready for operation.  
7. Restore power.  
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.  
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.  
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.

Operation  
1. After power has been connected to unit, fans will start  
NOTE: Air direction settings shown in Figures 6 & 7.  
in either preset (high/low) speed selection.  
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.  
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.  
4. For multiple unit applications (wide openings), mount  
units a minimum of 3” apart to allow for proper air  
intake and discharge.  
3. Air direction at outlet can be controlled by adjustable  
vanes at the nozzle which compensates for possible  
draft conditions.
