Air
curtains provide environmental separation at
openings by reducing the infiltration of unconditioned
air, fumes, dust, and humidity. At exterior openings,
they can resist winds up to 8 MPH (13 KPH) and are
generally mounted inside the building. During cold
seasons warm air that has risen towards ceiling is re-
circulated; they can also be used at interior openings
such as doors to coolers or clean rooms. |
|
Optimum
protection is provided when units are
mounted flush to the wall and as close to top of
door opening as possible. To ensure peak per-
formance keep air stream free of obstructions.
Air curtains may not be fully effective where negative
air pressure exists on one side of door. |
|
|
|
Series
CLC08 model air curtains have 1/5 HP motors.
They can be wall mounted or suspended from the
ceiling. |

MOUNTING INSTRUCTIONS (General) |
|
|
Before
mounting the unit, check the supporting structure
to verify that it has sufficient load-carrying capacity to
support the weight of the unit(s). The mounting hardware
(supplied by others) should be capable of supporting a
minimum of three (3) times the weight of the unit.
See TABLE 1. |
The
Certified Low Profile 7/Commercial Low Profile 8
air curtain is designed to be an ef.fective barrier against
cold drafts in the winter and hot air in the summer, flying
insects and airborne contaminants. To achieve optimum
protection, the unit should be mounted on the inside of
the building, flush to the wall and as close to the top of
the door opening as possible. To ensure peak per-
formance, keep air stream free of obstructions. |
|
|
|
|
|
|
|
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 door
opening. If the air stream strikes any obstruction
(the top edge of the doorway, a door opening
device, etc.), the ef.fectiveness of the unit will be
greatly reduced. See FIGURE 1. |
|
|
|
|
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. |
|
|
|
 |
|
|
|
|
|
|
|
|
B.
For optimum performance, the bottom of the unit |
|
|
|
(discharge nozzle)
should be no more than 1” above
the top of the door 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 door opening. Any void
between the air curtain and the wall should be
sealed along the full length of the unit.
See FIGURE 2. |

WALL MOUNTING |
|
| A.
Determine the location on the wall above the opening |
|
|
where
the air curtain will be mounted. This location
should center the unit over the opening and provide
suitable mounting support. It is recommended to use
at least four locations that correspond to the outer
corners of the wall mounting plate.
See FIGURE 3. |
|
|
|
|
|
|
|

plate anchors (by others). |
|
|
A.
When the unit is top mounted, the wall mounting |
|
|
plate
is designed to store on the back of unit for
future use. |
|
|
|
|
C.
Drill holes in the wall mounting plate to correspond
to the locations on the wall. |
|
|
|
|
|
|
B.
Four (4) factory installed #10-24 threaded inserts |
|
|
|
|
|
|
|
are
located on the top of the unit for top suspension
mounting. See FIGURE 5. |
D.
Anchor the wall mounting plate over the door
opening with the mounting tabs pointing upwards. |
|
|
|
|
|
|

|
|
|
|
|
C.
Determine the exact mounting location of the air
curtain. |
| E.
Raise the unit over the door (air nozzle facing |
|
|
down)
and onto the mounting plate. Tilt the unit
upward, matching the holes in the frame with the
tabs on the mounting plate.
See FIGURE 4. |
|
|
|
|
|
|
|
D.
The top of the unit is provided with an electrical |
|
|
|
knockout
for power connection. Remove the wiring
tray compartment cover. Remove the knockout and
attach necessary electrical hardware. Save the wiring
diagram found inside of wiring tray. |
|
|
|
|
| F.

ELECTRICAL CONNECTIONS |
|
All
electrical wiring and connections MUST be per-
formed 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. |
|
|
|
|
|
|
| A.
Check the electrical rating nameplate on the top |
|
|
|
|
 |
|
of the air curtain
for supply voltage and current
requirements. 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.
Remove the wiring tray cover; on air curtains that |
|
|
are comprised
of modules, remove the wiring tray
cover that is located closest to the electrical rating
nameplate (if it has not already been done).
See FIGURE 6. |
|
|
|
|
| D.
The top of the air curtain has two knockouts on |
|
|
each
side of the air curtain, allowing for a left hand
or right hand power connection. Remove the
required knockout if it has not already been done
and connect the power supply to the air curtain.
Connect all supply and control circuit wires
according to the wiring diagram provided. |

can be directly operated by using |
|
|
|
|
the
rocker switches located on the bottom of the
unit. The air curtain may also be automatically
operated by a combination of the rocker switches
and a remote door switch and/or thermostat
(See the wiring diagram). |
| VI.
MECHANICAL CONNECTIONS |
|
|
| A.
ELECTRICALLY HEATED MODELS |
|
|
|
The
heater circuit may be controlled by a combination
of a remote thermostat and the fan/off/fan & heat
rocker switch. Overheating protection is provided
by auto reset thermal cutouts built into the heater coil
assembly (see the wiring diagram, located in
wiring tray). |
|
|
|
|
|
|
|
|
2.
Rocker switch positions are labeled on the air
curtain cabinet. |
|
|
|
|
|
|
3.
Unheated units have one rocker switch that turns
the unit on or off. The other rocker switch selects
fan speed. |
|
|
|
|
|
|
|
|
|
|
|
4.
Heated units have one rocker switch that |
|
|
|
|
determines whether
the unit is off, energizes only
the fans, or energizes both the fans and the
method of heat. The other rocker switch selects
fan speed. |
 |
|
|
|
|
|
B.
AIR STREAM SPLIT ADJUSTMENT |
|
|
1.
With the air curtain operating and the door in its |
|
|
|
full open position,
check to see that nothing is
obstructing the air flow at the discharge nozzle
vanes. |
|
|
|
|
|
|
2.
Find the air stream split location. Hold a handker- |
|
|
|
chief, by its
corners, approximately 12” above
the floor. Gently move the handkerchief back
and forth in the doorway. Make sure the air is
being directed to both the inside and the outside.
The split location is indicated where the handker-
chief is vertical with minimal or no fluttering.
See FIGURE 8. |
|
|
|
|
|
|
3.
Adjust the discharge nozzle vanes so the split |
|
|
|
location is approximately
3” outside the doorway.
This is accomplished by first de-energizing the unit.
Remove the cover housing, loosen the nozzle vane
locking screws and adjust 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 vi-
bration, 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. To access the interior of the unit: |
|
|
|
|
|
| A.
Disconnect the power to the unit. |
|
|
|
|
|

Our
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. |

enough to allow the motor to move before the fans’
outer ball bearings pull out of the unit. |
