No. 70).
E. When cutting or drilling into wall or ceiling, do not damage electrical
wiring and other hidden utilities.
F. To reduce the risk of fire, do not store or use gasoline or other flammable
vapors and liquids in the vicinity of the air curtain.
G. This air curtain is hot when in use. To avoid burns, do not let bare
skin touch hot surfaces. Keep combustible materials, such
as furniture, pillows, bedding, papers, clothes,
etc. and curtains at least 1 inch from the top, back, front, sides and at
least
6 feet from the discharge of the air curtain.
H. Extreme caution is necessary when any air curtain is used by or near
children or invalids, and whenever the heater is left
operating unattended.
I. Do not operate any air curtain after it malfunctions. Disconnect power
at the service panel and have the air curtain inspected
by a reputable electrician before reusing.
J. To disconnect the air curtain, turn controls to “off”, and
turn off power to the air curtain circuit at main disconnect panel.
K. Do not insert or allow foreign objects to enter any ventilation or discharge

the heater off and inspect for any objects on or adjacent to the heater
that may have
blocked the airflow or otherwise caused high
temperatures to have occurred.
DO NOT OPERATE THE HEATER WITH THE ALARM SOUNDING (OR ILLUMINATING). |
|
|
|
|
|
I.
UNCRATING |
|
 |
|
Carefully examine
the carton(s) for damage. If the
carton is damaged, immediately notify the shipping
company. Do not delay in filing 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. |
|
|
|
|
|
Immediately verify

The Commercial
High Performance 10 & the Sanitation
Certified High Performance 7 Air Curtains are designed
to be an effective barrier against cold drafts in the winter
and hot air in the summer, flying insects and airborne
contaminants. |
|
|
|
|
|
To achieve optimum
protection, the air curtain 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 performance, keep the 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 makeup air to the building must be provided
so that the air pressure on both sides of the opening is in
balance. |
|
|
|
|
|
Before
mounting the air curtain, check the supporting
structure to verify that it has sufficient load-carrying
capacity to support the weight of the air curtain(s).
The mounting hardware (supplied by others) should
be capable of supporting a minimum of three (3)
times the weight of the air curtain.
See Table 1 or Table 2. |

|
|
|
A.
When determining the mounting location for the air |
|
|
|
|
curtain(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 open-
ing. If the air stream strikes any obstruction (the
top edge of the doorway, a door opening device,
etc.), the effectiveness of the air curtain will be
greatly reduced. See Figure 2. |
|
|
B.
For optimum performance, the bottom of the air |
|
|
|
curtain (discharge nozzle) should be no more than
1” above the top of the door opening with the air
curtain(s) mounted flush to the wall. If the air
curtain must be mounted higher, it must be
spaced out from the wall 3/8” for every inch
the air curtain is above the door opening. See
Figure 3. For optimum protection, any void
between the air curtain and the wall should be
sealed along the full length of the air curtain. |

CAUTION:
ELECTRIC SHOCK HAZARD
Disconnect power whenever servicing unit.
More than one disconnect may be required
to de-energize unit. |
|
|
|
|
|
|
|
|
Keep
your air curtain operating at peak efficiency by
cleaning the blower wheels, motor(s) and intake grill.
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 where 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. |

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 |
|
|
3.
Vacuum and scrape (if necessary) to remove |
|
|
|
|
|
the build-up of
dirt and debris. The motor(s)
are permanently lubricated and require no
additional lubrication. Re-install the cover
and intake grill. |
|
|
|
|
