MODEL NO. 670 AND 690 ROLL- FOLD®DIVIDER CURTAIN
OPERATIONAL INSTRUCTIONS
The 670 and 690 Divider Curtain is powered by an electric winch, which develops tremendous
forces. This equipment is to be operated only by qualified personnel to avoid structural damage or
possible injury to the operator and other individuals in the gymnasium.
Caution should be exerted at all times for safety reasons, keeping the following guidelines in mind:
x ONLY authorized, TRAINED personnel are to operate the 670 and 690 Divider Curtain.
Authorized personnel is defined as an individual (or individuals) who is at least 21 years of age,
has witnessed the proper operation of the unit, and is sanctioned by the facility as being
responsible for the operation of the divider curtain.
x The key switch or Powr-Touch® pad, which controls the divider curtain, must be flush mounted
on the wall, located in full view of the operator, and not directly beneath the equipment.
x Always make sure the area below the divider curtain and in the path of travel is clear of all
individuals when raising and lowering the unit.
x The divider curtain may be raised or lowered by placing the “UP” OR “DOWN” key into the key
switch, and turning as indicated on the switch cover plate. Refer to the separate Powr-Touch®
manual for the key pad type operation.
x The key that operates the unit should be retained at all times by a designated authorized person,
or kept in a lock box. Make sure that the key is never left in the key switch unattended!
x It is critical the operator visually monitor the area around the curtain through the entire raising
and lowering travel cycles, making certain no one is at or near the curtain travel. Pay particular
attention to the unit as it nears a limit switch cut-off juncture. If the limits are not stopping the
curtain at the “DOWN” position with minimal cable slack, or allowing the curtain to raise higher
than the top of the curtain fabric, contact your Porter representative immediately.
Again the safest equipment can be damaged when used by the untrained. It is imperative the
procedures set forth in this manual are strictly observed.
Note: The key switch must be labeled with the following operational instructions, as shown. If your
key switch is not labeled properly, contact your Porter dealer immediately.
WARNING
ENTRAPMENT OR EQUIPMENT FAILURE.

MODEL NO. 670 AND 690 MAINTENANCE CHECK LIST
Porter recommends a maintenance inspection take place at least once a year by a Porter Certified
Inspector, using the attached check list. Porter recommends the same check list be used as a
guide for additional inspections by facility personnel or operators every 6 months. Any abnormal
movement or sound during operation is cause for an immediate and thorough inspection. The annual
inspection by a Porter Certified Inspector is required to maintain the extended limited warranty.
1. GENERAL
Before inspecting, be certain to follow all OSHA guidelines concerning the use of scaffolds and
lifts. The proximity of the scaffold or lift to the curtain must be of adequate distance to provide
working clearance, so as not to have the curtain contact the lift during operational checks.
Make certain the Porter key switch, Powr-Touch®pad, or control system are not substituted and
is located within full view (but not beneath) the divider curtain. Check the walls in close proximity
to the curtain for any type of protrusion that may interfere with the raising or lowering of the unit
(i.e., new scoreboard, chinning bars, etc.).
2. ELECTRIC WINCH
Although virtually maintenance-free, the electric winch should also be periodically inspected for
proper operation of the limit switch assembly and key switch. Refer to the key switch/limit switch
instructions that come with the winch for adjustment procedure.
Inspect the connection to the superstructure, ensuring all hardware is tight. The hardware at the
building connection is also to be inspected for tightness. Ensure the lineshaft hardware is securely
attached to the winch with no sign of line-shaft “key-holing”
If Porter belt drive system is present, ensure belt it tight and that both pulleys are secure. Ensure
set screws and keys are tight.
If Porter 720 direct drive system is present, ensure gearing is free of obstruction and shows no
abnormal sign of wear.
Ensure Winch and line shaft systems are clear of power chords.
3. LINE SHAFT
Inspect the line shaft for proper rotation on the two (2) roller bearing wheels at each roller bracket
location. If the line shaft is not seated symmetrically on the two roller bearings, adjust the
turnbuckles accordingly.
Inspect the entire line shaft length for concentricity during rotation. If any part of the line shaft
rotates with a cam effect (wobble), replace that length of line shaft. Make certain the cause of
deflected shaft is identified and remedied, such as a roller support assembly being greater then 3’-
0” from a cable drum.
Inspect all hardware at line shaft splices and the winch output shafts, tightening as necessary.

10
4. LINE SHAFT SUPPORTS
All support fittings, shaft and pipe splices, support rods, etc. should be inspected for fatigue
cracks, loose bolts or set screws, and corrosion, on an annual basis. Replace defective parts as
required.
5. ROLLER BRACKET SUPPORTS AND TOP CURTAIN CONNECTIONS
Inspect all turnbuckles and “S” hook connections, making certain the hardware is all “closed”.
Alignment of the roller assembly is to be inspected for a smooth rotation of the line shaft.
6. HOISTING CABLES
Inspect all 1/8” galvanized hoisting cables for kinking or fraying, replacing as necessary.
7. CABLE DRUMS
Make certain all cable drums are secured with two (2) 5/16” x 7/16” lg. rivets or self drilling screw,
and not just a set screw. All cable must be within the side drum plates. If any cable is winding
outside the drum on the line shaft, this is an indication of an incorrect up or down limit switch
adjustment. Refer to the limit switch section of this manual for adjustment procedure. Adjust so
that the cable has minimum build up on itself through the travel of the curtain by adjusting the
location.
8. TOP AND BOTTOM CURTAIN POCKET CONCEALED PIPES
Inspect both the top and bottom pockets, ensuring the concealed pipe is not separating. At the
bottom hem, the pipe is to be secured to the fabric at each cable line with a 5/16” bolt through the
curtain, the bottom pipe, and secured with a cap nut (see Figure O). If padded bottom tube is
present, confirm padding does not need replaced.
9. SUPERSTRUCTURE
Visually inspect all super structure and connections for any sign of abnormal deflection or
structural cracks. Check all hardware to confirm it is present and secure.
10. FABRIC
Inspect the curtain for any tears or holes in the fabric. Additional fabric can be obtained through
Porter Athletic, to be used for patching. Industrial vinyl cement will easily bond the vinyl patch to
the curtain. Also, check the fabric for signs of tearing or loosening at the seams. Check grommets
at all pullup lines. The fabric may be cleaned with a mild solution of soap cleaner and water, or
Power Foam sold by Rigmar Industries of Elk Grove Village, Illinois (1-800-323-0779).
11. UNIVERSAL JOINTS (690 CURTAIN ONLY)
Check that each universal joint is properly free to allow for proper transferring of the rotation of the
line shaft. Lubricate if necessary. Ensure all hardware is secure.

INSTALLATION INVENTORY AND INSPECTION
Inventory parts listed on the packing list to ensure parts required are accounted for. Inspect all
components for possible shipping damage. Report any shortages to Porter’s Customer Service
Department immediately. On visible freight damage, sign as damaged, and file a freight damage
claim with the carrier immediately. Failure to report shortages or hidden freight damage directly to
Porter’s Customer Service Department within three working days will place the financial burden for
the missing or replacement parts with the installer or general contractor.
PREPARATION OF ASSEMBLY AREA
Moving the curtain after assembly is both difficult and awkward. For that reason, the assembly of the
curtain should take place below or near the curtain overhead support location. The floor should be
protected with a suitable material, covering the entire length of the curtain in the assembly area to
prevent damage to the floor or curtain. In addition, the floor and the covering must be free of any
debris generated from assembly procedures prior to fabric installation.
TOOLS / EQUIPMENT REQUIRED
To Be Provided by the Installer:
x Scaffold or Lift
x Hand tools, electric drill, drop cord, vise grip pliers, etc.

690 LAYOUT INSTRUCTIONS
NOTE: FOR RADIUS CURTAINS ONLY
The layout of the 690 curtain is one of the hardest and most important steps during the install of the
curtain.
Start by locating the center radius and reference points. Porter tries to locate everything from this
point, so check its location using striping and other references.
If possible, take a string to the radius point and measure on the string the exact radius. With one
person holding the string at the center point, another can mark out the curtain profile. The cable
pickup points correspond with grommets in the fabric, so it is important to locate these first. Mark the
cable pickup points along the line.
Next, determine the winch locations and mark that on the floor. Locate the line shaft supports. These
should be close to the radius but may not be exactly on. Check to make sure the provided line shaft
lengths will allow these support fittings. The more you are able to make the line shaft curve the
better the operation. The line shaft supports can be moved slightly to make this work but the cable
pick up points should stay above the grommets.

15
INSTALLATION OF WINCH AND LINE SHAFT
1. Unpack and check all parts and verify quantities with packing list. Verify the location of the curtain
with the architectural prints. If the winch location needs to be relocated from the installation prints,
the line shaft lengths may not work. Contact the factory immediately for additional splices or line
shaft lengths. If the curtain is to be located on a court centerline, be sure to consult with the
architect's "court striping plan." Notify the owner, project superintendent or architect if conflicting
situations arise. Do not proceed with installation until all conditions are clarified and settled.
Failure to do so may result in relocating the curtain at the installer’s expense! This step is
critical!
2. Locate centerline of curtain on gymnasium floor. Study curtain installation drawings and all details
of roller bracket assemblies, drum cable assemblies and winch mounting assembly before
proceeding with installation. Make certain the curtain will clear all potential obstacles (HVAC,
backstops in the up AND down position, etc.).

INSTALLATION OF WINCH AND LINE SHAFT
3. With the winch sitting on the floor, and the floor area protected, slide the 2-3/8” O.D. line shaft
completely into the winch coupler(s). The installation prints will call out the proper sequence
lengths of the line shaft. Support the opposite end of the line shaft before drilling. Utilizing the two
existing holes in the winch coupler as guides,
drill one 17/32” diameter hole through both
walls of the line shaft. Secure the line shaft to
the coupler by inserting one 1/2” x 3-3/4” lg.
grade 5 cap screw provided, before drilling the
second hole (See Details “B” or "C"). This will
keep the line shaft in place and provide proper
alignment for the second hole. Now drill the
second hole, utilizing the additional hole in the
line shaft coupler. Insert a second 1/2” cap
screw to ensure a proper fit. Now remove the
two 1/2” cap screws, and remove the line shaft
section from the winch assembly.
4. On the opposite end of
the line shaft in which
the two 17/32” diameter
holes were drilled,
scribe a line 6” from the
end (opposite of the
holes). Now slide the
line shaft coupler on to
the shaft, and drill a
5/16” diameter hole at
the pilot hole, through one wall of the shaft. Secure the coupler to the shaft with a 5/16” x 7/16” lg.
drive rivet. (See Detail “D”) This will now allow you to drill a 17/32” diameter hole through the line
shaft at the pilot hole for this size, without the shaft turning. Insert the 1/2” x 3-1/2” lg. grade 5 cap

INSTALLATION OF WINCH AND LINE SHAFT
6. Locate the winch support adapter, and mount as detailed on the project-specific installation prints.
7. Now secure the winch to the winch support adapter, and attach with the four (4) 3/8” x 1-1/2” grade
5 cap screws, lockwashers, and grade "C" convex lock nuts. The winch coupler (output shaft) now
determines the elevation for the line shaft. Sight down the length of the curtain area to determine if
there is any interference with the shaft location. If interference exists, contact the factory. A
longer winch adapter and drop brackets may be required.
8. Now mount the first and second roller support attachments to the support structure as detailed and
dimensioned on the installation print. The brackets are provided with vertical adjustments to level
the line shaft. See Details on pages 14 or 28 for typical line shaft support attachments. See
installation drawings for job-specific details.
9. Referring to the installation drawing, determine how many drums must be slid onto each section of
line shaft before proceeding. Just before securing the line shafts to the winch and to the coupler, it
will be necessary to slide the proper amount of drums onto each section.
10. Slide the pre-drilled line shaft assembly from step no. 3 into the winch coupler output shaft (15),
and support the opposite end from the roller bracket. Is the drum slid onto the shaft? Secure the
shaft to the winch coupler, utilizing two (2) 1/2” x 3-3/4" lg. grade 5 cap screws, and secure with
1/2” grade "C" convex locknuts, tightened to a minimum 20 ft/lb setting (See Detail “D”).
11. After the first line shaft section is in place, secure the next section (from Step No. 5) to it. Slide the
next section into the line shaft coupler until it bottoms out on the previous section. Drill for and
install the 5/16” x 7/16” lg. drive rivet. Then drill for and install the 1/2” x 3-1/2” lg. grade 5 cap
screw, and secure with a 1/2” grade "C" convex locknut, to a minimum 20 ft/lb setting. Repeat for
all remaining line shaft sections. (See Detail “D”).
12. Make certain the line shaft is level. This is critical to the proper operation of the unit. Adjust as
necessary at each roller support attachment. DO NOT PROCEED UNTIL THE LINESHAFT IS
LEVEL!

LINE SHAFT SUPPORT
1. Ideally, the roller support brackets are to be 1'-0" offset from the take-up cable lines (again, refer to
the installation print). If an obstruction occurs at the dimensioned support location, the offset
maybe increased, but never more then 3'-0" from the take-up cable line. Refer to Detail "F" for a
typical roller support attachment.
2. Attach the turnbuckles and roller support brackets as shown. Be certain to crimp the turnbuckle
hooks closed. Attach the 5/16" "S" hooks to each end of the 3/16" chain, and hook on to the roller
support bracket. The chain will secure the top pipe in the curtain hem to the structure.

ASSEMBLY AND ADJUSTMENT OF CABLE DRUMS
Center the cable drum assemblies (as installed in step 9) on the shaft per the dimensions given on the
installation print. Check the centerline of each cable drum to ensure the location is correct. The cable
drum location can be marked on the floor with tape, and transferred up to the line shaft by a plumb
bob or laser. The cable drums are not to be secured with rivets to the line shaft until the curtain fabric
is in position. Spin the drums so that all the cable holes in the side plates are facing directly toward
the floor (this will help with the adjustment of the drums). Once this is done secure the drums in place
temporarily with the set screw located on the drum (See Detail “G”).

PREPARING THE FABRIC FOR INSTALLATION
1. Clean the floor area (with broom and dust mop) and unfold curtain fabric. If working over an
unfinished floor, lay out a tarp to keep the fabric from picking up dust and dirt.
2. When laying out the curtain, have the grommets in the bottom pocket facing up. Position the
bottom of the curtain close to the centerline of the drive shaft so that the initial folding leaves the
top on top.
3. Once the support chain locations are properly
transferred to the fabric, the next step would
be to cut out semi-circles with a utility knife in
the top pocket. Be certain to protect the
finished floor before commencing. A roll of
tape or 3 1/2" pipe cap can be used as a
template to provide a neat cut (See Detail
"H"). The material at the top pocket can also
be slit after the fabric is hoisted in the air to
secure the chain support around the top
1 5/16" tube.
4. Sleeve the 1 5/16" O.D. tubing in the top pocket of the curtain, taking care that the sleeves are
fully engaged. Note that the tubing will be longer then the curtain fabric. Each splice must be
secured with a minimum of four (4) 3/16" x .45 Lg. rivets. (See Detail "I"). (Installers may want to
wrap splices with duct tape so that heads of rivets do not cut or hang up on the mesh when sliding
the top tube through the top pocket.)
5. Taking care to protect the finished floor, slit
the bottom pocket below each grommet line,
2" up from the bottom, through both vinyl walls
(See Detail "J"). Sleeve the 1 5/16" O.D.
tubing in the bottom pocket, ensuring the
weighted tubing with a hole drilled at one end
is at each end of the curtain. Again, each
splice must be secured with a minimum of four
(4) 3/16" x .45 Lg. rivets. Install a plastic cap
at each end, making certain the cap is fully
engaged on the tubing. Using a utility knife,
slit the cap at the hole location, creating an
access for the 3/8" x 2 1/2" Lg. (3 1/4" Lg. for
curtains with a padded tube) round socket
head cap screw. Insert the cap screw through the curtain grommet,
tubing and through the opposite curtain grommet,
and secure with a 3/8" lock type acorn nut (See Detail "K").
6. Once the bottom
tube is secure you
must then route the
cable through the
vertical grommet lines,
it may be advantageous
to insert a 3/8" hollow
tube through the grommet
lines, with the fabric folded in
an accordion manner, but is
not necessary (See Detail "M").
