2 Product description
2.1 Function and design of this door
The model Re-Coil-Away is a vertically opening door.
2.1.1 Principle
The door assembly consists of left and right side frames and a header assembly. The header
assembly contains the curtain and the drive system already attached. The bottom beam is
already attached to the curtain. Door comes standard with a balance system.
The Re-Coil-Away door rolls the curtain material directly on and off a barrel assembly. The
edges of this curtain are contained within the side frames via a patented windlok system
while the curtain is being rolled or unrolled off the barrel. These side frames guide the curtain
also and provide a seal.
The bottom beam, located on the bottom of the curtain, contains a continuously monitored
pneumatic safety edge. Activation of this device will stop the door and cause the door to
reverse to a fully open position. The door also has a reversing photocell attached to the side
frames of the door.
2.1.2 Door Speeds
The maximum opening speed depends on the size of the door and sprocket size.
Door Size
1-Speed
Up to 12’ x 12’
18” per sec.
12’ x 12’ to
18’ x 18’
15” per sec
Measured at 8 feet high.
2.2 Electric safety features
Before each downward movement an internal test of the photocells and the control unit is
performed (Safety classification 2). If a malfunction has been acknowledged, the drive power
is interrupted (ACS-50 Control Panel) and the door will not operate to close the door.

Product Description
2.2.1 Additional Safety systems
Depending on the kind of application it may be useful to have additional sensors as safety
features. This is especially true for a door with a high volume of human traffic or with low
sized doors with a height under 10 feet (3m).
Albany Door Systems offers a variety of safety systems for high-speed doors. Some
examples could be any of the following: Light beam barriers, motion detectors, induction
loops. For any other electrical requirement contact us at the factory.
2.3 Drives
The Re-Coil-Away is operated with an electrical drive. Drive side is chosen by the end-user.
The drive system has a 1-speed operator. The drive systems come in 3 different operating
voltages: 208 VAC, 460 VAC, and 575 VAC.

5.3 Starting the install
5.3.1 Setting up the side fames
NOTE: Some wall surfaces are not ideal
and may require shimming to keep the side
frames square to each other. This will help
eliminate photocell misalignment problems
and curtain binding issues.
The door is usually centered over the door
opening. Also at this time establish a level
line or mark on each side of the door
opening (must be marked in order to
establish a reference height in case of an
uneven floor). This can be accomplished
using either a water level or an optical
measuring device. Measuring down from
this mark to the floor on each side of the
door opening will tell you if your floor is level
at the points of installation for each of the
side frames.
Door Height Opening
Door Width Opening
Figure 1
(Example: If on side A, you measure from
your level mark to the floor and it 46” and
side B it measures 47”. This measurement
tells you that Side A should be installed first
right on the floor and that Side B will have to
be raised 1” in order to be level with Side
A). See figure 1.
Mounting holes
Once you have established which side
frame to install first. You need to put up this
side frame up and fully plumb and level it,
as seen in figure 2. Centering the door in
the doorway opening will allow for minor
variations in the existing door opening
NOTE: Along the inside of each side
frame there are predrilled holes for
mounting the side frame to the door
opening. (See Appendix)

5.6 Drive Chain Tension
Figure 11 is a finished header assembly that has been installed. Also note the idler barrel
has been bolted back into place back.
Chain tension should be checked after the door is cycled a few times.
Slack side
The M&I drive chain is to be tensioned so the deflection of the slack side (bottom side) of the
chain is equal to 2% of the distance between the shafts. For door over 12’ x 12’ this value is
3/8” (9.5 mm). For doors under 12’ x 12’ this value is
9/32” (7.1 mm).
5.6.1 Operator assembly
The operator is not assembled to the door when it is
shipped. On the drive side of the header assembly, 4
weld studs serve as attachment points for the operator.
When assembling the operator, the slots on the
operator mounting surface should be centered on the
studs Tighten using the provided flat washers and nuts.
Assemble the chain.
5.6.2 Chain Tension Adjustment

5.8 Hand Chain Operator
The operator is equipped with an emergency chain hoist and floor-level disconnect
mechanism to operate the door manually, if necessary. To manually operate the door:
Pull the disconnect chain downwards to the “disengaged” position (See figure 14a). A
positive engaging coupling disengages the initial drive mechanism from electrical operation
and transfers it to manual chain hoist drive. A switch disconnects the electrical controls to
prevent injuries.
Operate the door manually by pulling downward on one side of the chain. Pulling the other
side will cause the door to move in the opposite direction (See figure 14b).
To return to electrical operation, merely pull the disconnect chain to the “engaged” position”
(See figure 14c)

Curtain tends to 'cone' in one direction on the barrel, as the door is rolling up.
What is a wedge?
A wedge is a piece of waste rubber (can be as large as 6" square by as much as 1/2"
thickness), which is strategically placed on the drive barrel between the curtain and the
barrel. It is secured with a self-tapping screw(s).
How to determine where to fasten wedge.
It is normal for a curtain to 'float' slightly from side to side as the door rolls up and down.
Wedging is required only when there is a severe tracking problem such as listed above.
The placement of a wedge can be determined in several ways. For example, if the bottom
bar were tracking to the left as the door is opening, then the wedge would be fastened on the
right end of the barrel. The wedge would then make the curtain roll-up faster on the right
side, thus making the bottom bar track evenly between the guides. Should the door be
tracking to the right, and then obviously the wedge should be fastened to the left end of the
barrel.
It is important to identify whether a door requires a wedge or if it has been installed out-of-
level. For instance, if a door rolls down with the bottom bar continually tracking to one side,
eventually jamming near the floor, yet the curtain does not appear to 'cone', then the door is
most likely out-of-level. To remedy the problem, it may be necessary to raise one of the end
plates (which have slotted holes) to level the door.

6.5 Repairs & Removals
6.5.1 Removal and Re-installation of curtain in guides
1. Utilizing a 3/8” wrench, unbolt the hinged front guide plates of both the left and right
guides. Swing the front guide plates open and place them to the side.
2. In the event that only the upper portion is hinged, raise the curtain and bottom bar until
the bottom bar front angle is just below the open hinged portion. Then, lift the curtain
one end at a time, out of the guides and set it outside the front guide plates.
3. Lower the curtain slowly and make sure that it does not catch on the guides. To re-
install the curtain, follow the above steps in reverse order. Be sure to close and bolt the
front guide plates prior to putting the door back into operation.
6.5.2 Removal and Re-installation of curtain in bottom bar
1. With the curtain and bottom bar supported on a flat surface, loosen the bolts which
secure the bottom bar to the curtain.
2. Slip the curtain out of the bottom bar. To re-install the curtain back into the bottom bar,
follow the above steps in reverse order.
If the bottom bar is equipped with an electric reversing edge, be sure to unplug the connector
when removing the bottom bar. In addition, take extreme care not to damage the electric
reversing edge fabric. A puncture would allow moisture to penetrate it, thus causing
premature failure of the reversing edge.
6.5.3 Repairs to rubber curtain – rips or perforations
In order to work on the ripped or perforated area, the curtain must be taken out of the guides
and lowered to the floor. Then, either work on an area supported by the floor or alternatively,
a solid, level surface provided by a heavy table, for example. Refer to Figure 31 and 32 for
positioning of the curtain prior to repairing it.
1. Using a utility knife, set it to a depth that will penetrate the rubber down to the nylon cord
centre of the curtain and cut a rectangular or square section approximately 2" wider than
the sides of the rip or perforation. Be careful not to cut the nylon cord itself (see Figure
31).
2. Using a screwdriver and pliers and starting at one corner of the cut, peel the surface
from the nylon cord centre within the perimeter of the cut.
3. Using coarse sandpaper or a wire brush, remove loose rubber particles from the nylon
cord centre. However, it is not necessary to have the fabric 100% bare.
4. Flip the curtain over to the other side of the rip or perforation and repeat Step 1 through
Step 3.
5. From the 1/8" thick piece of repair rubber, cut some pieces to inlay into the prepared
areas. Using a grinder with a sanding disc or a wire brush, roughen-up the inlay
surfaces for bonding.

6. Mix the adhesive as per the manufacturer's instructions and apply a liberal coating to the
nylon cord fabric and the rough surfaces of the inlay rubber segments. Allow pieces to
dry to the touch (about 15 to 20 minutes) and apply a second coating. Allow to set until
tacky. Place the inlay segments into position and, using a rubber or rawhide mallet and
a steel buckler, impact the entire area of the patch repeatedly. A high degree of impact
ensures proper adhesion. Clamping is not acceptable. Allow the cement to cure
thoroughly (1-1/2 to 2 hours) before moving the curtain.
7. Finally, raise the curtain to an open position, re-insert it into the guides, close and re-bolt
the guides, and resume normal operation.
