Uncrating; Wall Mounting - Berner ALC08 Series Installation & Maintenance Instructions Manual

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 se-
curing the carton(s) to the skid. Open the carton(s) and remove
all protective packaging. Immediately verify that the electrical
rating nameplate located on the cover matches 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 or in a separate carton(s) accompany-
ing the air curtain(s). Check all of the cartons/skids for accesso-
ries before discarding.
II. MOUNTING INSTRUCTIONS
(General)
INDOOR MOUNTING ONLY - Environmental/Insect/Dust Control
The Architectural Low Profile 8 Air curtain is designed to be an effec-
tive barrier against cold drafts in the winter and hot air in the summer.
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 veri-
fy 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.
IMPORTANT: A minimum of 1" is required above the top of the
air curtain for the installation and removal of the cover housing.
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 0º to 20º toward the door opening.

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 1.
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.
C. Electric heated air curtain(s) shall:
1. Have a minimum clearance of at least 1"
between the sides and top of the air curtain and
any combustible material.
2. Have a minimum clearance of at least 6'
between the bottom of the air curtain and the floor.
3. Be installed Indoors Only.
D. Proceed to either Section III - WALL MOUNTING
or Section IV - SUSPENDED MOUNTING
III. WALL MOUNTING
A. The Architectural Low Profile 8 Air curtain is equipped with
two ¼" threaded inserts on the back of each air curtain (two
per module on air curtains 84" and over). Insert and
tighten the shoulder bolts (provided in bag taped to the
wall plate) into these threaded inserts. A minimum of two
shoulder bolts are required; on air curtains comprised of
modules, use the outer threaded inserts and a minimum of
one of the inner threaded inserts.
