temperatures to have occurred. DO NOT OPERATE THE HEATER WITH THE ALARM
SOUNDING (OR ILLUMINATING).
UNCRATING
Carefully examine the carton(s) for damage. If the carton is damaged,
immediately notify the shipping company. Do not delay in filing a claim. If
the air curtain(s) were shipped on wooden skids, remove protective wood and
banding straps securing the carton(s)
to the skid. Open the carton(s) and remove all protective packaging.
If the unit will be wall mounted, remove and save the locking screws from the
wall plate and detach and set aside the wall mounting plate.
Immediately verify that the electrical rating nameplate located on the cover
matches the electrical power supply available. Retain the shipping carton(s)
until the air curtain(s) are installed and properly operating.
ACCESSORIES : If the air curtain(s) were ordered with optional electrical
accessories, the accessories will be found in the carton containing the air
curtain packed in a red bag (marked “additional parts inside”) or in a
separate carton(s) accompanying the air
curtain(s).
Check all of the cartons/skids for accessories before discarding.
NOTE : Unheated models come with a remote mounted switch.
MOUNTING INSTRUCTIONS (General)
The Pass-Thru 6 air curtain is designed to be an effective barrier against cold drafts in the winter and hot air in the summer, flying insects and airborne contaminants. Series# PE06 is UL certified for Outdoor Mounting and may be mounted inside or outside, whereas Series# PT06 is UL certified for Indoor Mounting only. To achieve optimum protection, the unit should be mounted flush to the wall and as close to the top of the opening as possible. To ensure peak performance, keep air stream free of obstructions.
The air curtain will not perform properly if negative air pressure exists in the building. Under these conditions, a means for make-up air to the building must be provided so that the air pressure on both sides of the opening is in balance. Before mounting the unit, check the supporting structure to verifythat it has sufficient load-carrying capacity to support the weightof the unit(s). The mounting hardware (supplied by others) should be capable of supporting a minimum of three (3) times the weightof the unit. See TABLE 1.
A. When determining the mounting location for the unit(s), make sure that
nothing interferes with the curtain of air developed when the discharge vanes
are directed from 0° to 20° toward the opening. If the air stream strikes any
obstruction (the top edge of the opening, a window opening device, etc.), the
effectiveness of the unit will be greatly reduced. See FIGURE 1.
B. For optimum performance, the bottom of the unit (discharge nozzle) should
be no more than 1” above the top of the opening with the unit mounted flush to
the wall. If the unit must be mounted higher, it must be spaced out from the
wall 3 /8” for every inch the unit is above the opening. Any void between the
air curtain and the wall should be sealed along the full length of the unit.
See FIGURE 2.
C. Do not block (obstruct) the air intake grill. Insufficient airflow can
cause the unit to overheat.
D. Electric heated air curtain(s) shall:
- Have a minimum clearance of at least 1” from the sides and 1″ from the top for electric heated units.
- Have a minimum clearance of at least 6’ between the bottom of the air curtain and the floor.
- Be installed Indoors Only.
E. Proceed to: Section III-WALL MOUNTING or Section IV-SUSPENDED MOUNTING

B. Four (4) factory installed #10-24 threaded inserts are located on the top
of the unit for top suspension mounting. See FIGURE 5.
C. Determine the exact mounting location of the air curtain.
D. Install #10-24 threaded rods, or other suitable hardware at a location
sufficient to support the air curtain. The mounting hardware (supplied by
others) must be capable of supporting a minimum of three times the net weight
of the air curtain.
See WEIGHT CHART, TABLE 1.
E. Attach #10-24 threaded rods, or other suitable hardware to the top mounted
threaded inserts.
F. Proceed to Section V-ELECTRICAL CONNECTIONS
ELECTRICAL CONNECTIONS
All electrical wiring and connections MUST be performed by qualified personnel in accordance with the National Electrical Code ANSI/NFPA No. 70 (latest edition) or, in Canada, the Canadian Electrical Code, Part 1-C.S.A. Standard C22.1 and local codes and regulations. Check the electrical rating nameplate on the top of the air curtain for supply voltage and current requirements.
A. A separate line voltage supply with a suitable branch circuit protection
device should be run directly from the main electrical panel to the air
curtain. A disconnect switch for each branch circuit is a required part of
this installation.
B. All field wiring must be copper with a minimum insulation of 60° C within
approved conduit. If any of the wire supplied with the air curtain must be
replaced, it must be replaced with copper wiring with a minimum insulation of
90° C.
C. On top of the air curtain, remove the wiring compartment cover. See FIGURE
6.
D. Remove the required knockout(s) and connect the power supply to the air
curtain. Connect all supply and control circuit wires according to the wiring
diagram provided. NOTE : For Electrically Heated air curtain(s) provided
with the optional remote thermostat: mount and wire the thermostat according
to instructions and wiring diagram.
NOTE : For Electrically Heated air curtain(s) – Overheating protection is
provided by auto reset thermal cutouts built into the heater coil assembly
(see the wiring diagram, located in wiring tray).
OPERATING INSTRUCTIONS
A. GENERAL OPERATION
-
The air curtain can be directly operated by using the rheostat variable speed switch:
Series# PE06 – Unheated units use a remote mounted rheostat variable speed switch that is shipped loose and is located in the red bag.Series# PT06 – Heated units include a built-in rheostat variable speed switch and a built-in heat on/off switch on the bottom of the air curtain. Units ordered with a remote mounted rheostat variable switch have no heat on/off switch; the heater is operated via the thermostat. -
Unheated units have one rheostat switch that turns the unit on or off and provides fan speed control.
-
Heated units have: 120V – one rheostat switch per motor, 208/240V – one rheostat switch per unit, that turns the unit on or off and provides fan speed control, and another switch that turns on or off the electric heater. Units outfitted with remote rheostats do not have a heat on/off switch.
-
The air curtain may also be automatically operated by a combination of the rheostat switch and a remote door switch and/or thermostat (See the wiring diagram).
B. RHEOSTAT FIELD ADJUSTMENT
- Locate the hole in the nameplate for access to the adjusting screw.
- Insert small Phillips screwdriver in hole and gently turn POT in proper direction to change speed.
- A very small degree of rotation is required to change speed, wait for speed to settle, then change a little more if needed.
- Test full range, turn knob to high speed to check for variation.
- Ambient unit low speed should be about 1050 RPM, Electric heated unit low speed should be about 1250 RPM.
See FIGURE 7.
WARNING : SETTING POT TOO HIGH MAY CAUSE MOTOR TO STALL ON LOW SPEED.
IF SPEED IS TOO LOW ON ELECTRIC HEATED UNITS, YOU CAN CREATE ABNORMAL
POTENTIALLY HAZARDOUS TEMPERATURES CAUSING THE HEATERS TO TRIP OUT THE THERMAL
CUTOUTS INTERMITTENTLY.
C. AIR STREAM SPLIT ADJUSTMENT
-
With the air curtain operating and the window is in its full open position, check to see that nothing is obstructing the air flow at the discharge nozzle vanes.
-
Find the air stream split location. Hold a handkerchief, by its corners, approximately 12” above the counter. Gently move the handkerchief back and forth in the window. Make sure the air is being directed to both the inside and the outside. The split location is indicated where the handkerchief is vertical with minimal or no fluttering.
See FIGURE 8. -
Adjust the discharge nozzle vanes so the split location is approximately 3” outside the opening. This is accomplished by de-energizing the unit, loosening the nozzle vane locking screws and adjusting vanes.
MAINTENANCE AND CLEANING
CAUTION : ELECTRIC SHOCK HAZARD Disconnect power whenever servicing air
curtain unit. More than one disconnect may be required to de-energize air
curtain unit.
Keep your air curtain operating at peak efficiency by cleaning the blower
wheels, motor(s) and intake grille. Buildup of dust on the blower wheels can
cause vibration, noise and excessive wear on the motor bearings. The frequency
of cleaning will depend on the environment in which the unit is operating.
Dirty, dusty or greasy environments could require a cleaning schedule of once
every two months. If the environment is not that dirty, the unit(s) should be
scheduled for cleaning a minimum of once every (6) months.
A. PERFORMING PREVENTATIVE MAINTENANCE
-
Disconnect the power to the unit.
-
Remove the intake screen by removing all Phillips head screws around the edge. See FIGURE 9.
-
Vacuum and scrape (if necessary) to remove the buildup of dirt and debris. The motor(s) are permanently
lubricated and require no additional lubrication.
Reinstall the cover and intake grille. -
Reconnect the power, and turn on after cleaning.
CAUTION : STAND CLEAR OF THE UNIT OR WEAR SAFETY GOGGLES AS LOOSE DEBRIS MAY BE PRESENT AND MAY EXIT THROUGH THE NOZZLE.
SERVICE
CAUTION : ELECTRIC SHOCK HAZARD Disconnect power whenever servicing air
curtain unit. More than one disconnect may be required to de-energize unit.
Any service performed on the Pass-Thru 6 air curtain MUST be done by qualified
personnel.
Berner air curtains require very little servicing. All parts are easily
accessible for periodic inspection and maintenance.
Units should be cleaned at least twice a year. Your particular application
(the amount of dirt and dust in the air) and location of the unit(s) will
determine how often your unit(s) will need to be cleaned and serviced. All
motors have permanently lubricated, sealed, sleeve bearings and require no
maintenance.
A. FAN AND MOTOR REMOVAL
- Disconnect power to the unit.
- Remove the intake screen by removing all Phillips head screws around the edge. See FIGURE 9.
- Unplug motor harness from motor and remove necessary wiring.
- Using a 1 /8” Allen wrench, loosen each set screw attaching fan(s) to motor.
- While holding the motor in place, loosen and remove the motor clips.
- Slide the fans toward the motor so that the ball bearings on the outer fan shaft are exposed.
- Slowly roll the motor out of the motor mount cradle forward and down. The hubs of the fans are flexible enough to allow the motor to move before the fans’outer ball bearings pull out of the unit.
- Reinstall in reverse order of removal.
