Joining Door Sections with Cam Locks

CAUTION: All parts have been pre-assembled at the factory. No Drilling shouldbe required. Be careful to not overdrive anyfasteners.

Doors over 120� inches in width must be fieldassembled as follows:

1. Begin by laying the sections of the door face downon a clean and level surface. Block as needed sothe door sections are aligned. See Figure 4.

2. Apply silicone caulk to both long edges, then slidethe door sections together. Cam lock the sectionswith a 3/8� hex wrench (supplied). Turn clockwiseuntil the lock is engaged with the Hinging pin.See Figure 5.

3. Note that interior and exterior surfaces of the doorsections along the joint should be flush andsmooth. Install cam hole covers.

4. Remove the Adjuster Rod and Jam Nuts. Installthe 10 gauge Metal Plate at the top and the bot-tom of the door. Anchor the strips with #14 x 1-1/2�Phillips flat head screws that have been provided.Reinstall the Adjuster Rod. See Figure 6.

Hanging Door Section on Track Hanger Channel1. Install the Track Hanger Channel on top of the

door. Fasten it to the door with the Square Wash-ers, flat washers, Jam Nuts, nylon Lock Nuts, and3/4� Adjuster Rods. Make sure the Adjuster Rodcomes through the nylon Lock Nut on the SquareWasher no more than 1/16�. Adjust the TrackHanger Channel temporarily to 3-3/4� from the topof the door to the bottom of the Channel. Finaladjustment is made after the Door is hanging onthe Door Track. See Figure 7.

2. Place the door section next to the door openingand lean it against the steel Door Track. Be carefulto not damage the Sweep Gasket at the bottom ofthe door section.

3. Lift the door and place the Track Rollers on theRound Welded Rod of the Door Track.

4. Install the Anti-Jump Bolt or Anti-Jump Roller tokeep the door on the track. Adjust to a gap of 1/8�.See Figure 8.

Adjusting the Door Height1. For a single slide door, set the door in the closed

position and adjust the door height so the SweepGasket lightly touches the floor and the door linesup with the side frames. See Figure 9. To adjustthe height, loosen both the top and bottom JamNuts and raise or lower the door with the weldednut on the Adjuster Rod. See Figure 7.

2. For a bi-parting door, set the doors in the closed position and adjust the door height so the Sweep Gasketlightly touches the floor. Use the Adjuster Rod to align the two door sections for a proper seal where thedoors come together. Begin by adjusting the door height to produce a slight gap (approximately 1�) at thetop of the doors, when the bottom of the doors are just touching. This should allow the doors to seal com-pletely from top to bottom, when fully closed. Readjust as necessary to achieve a uniform seal. See Figure9. To adjust the height, loosen both the top and bottom Jam Nuts and raise or lower the door with theAdjuster Rod. Tighten the Jam Nuts to lock the door in position. See Figure 7.

Stay Roller Installation1. The purpose of the Stay Roller is to keep the

bottom of the door against the gaskets in theclosed position and to keep the door from kickingout at the bottom when moving.

2. For shipping purposes, the Stay Roller assembliesare secured on a piece of wood located on thefront side of the Door Header. Remove them andthe eight capscrews and lockwashers for installa-tion. See Figure 10.

3. Be sure each Stay Roller Lock Nut is centered inthe adjustment slot. Note the distance from thewall for your door size and type. See Figure 11.With the door(s) fully closed, position the center ofthe Trailing Edge Stay Roller 3/4� in from the endof the Door Snubber Wedge. For Single SlideDoors, center the Leading Edge Stay Roller on theflat spot on the Door Snubber. This will also posi-tion the left side of the bracket flush with the dooropening. See Figure 11.

4. Use four 3/8� x 2-3/4� concrete wedge anchors tofasten each Stay Roller to the floor. See Figure 12.

Pull Cord InstallationThere are many types of devices used to control door operator. The most common are pull cord switches orstations, three button stations (i.e. open, close, stop) and radio–control. All three may be used separately, incombination, or all together. Our descriptions will deal with separate devices only. However, to use more thanone type of device, you need only follow the direction for each type of device used. The control circuit is24 VAC. Consult local electrical codes before proceeding with permanent installation.

Pull Cord SwitchAir Baffle

CoolingCoil

431521

Locate the Switches1. Do not mount the pull cord switch in the air flow of

the coils. If the pull cord switch must be mountedin front of the coils, provide an air baffle (by others)to prevent icing of the switch. (Icing of the switch inthe open position will cause the door to runconstantly.) The air baffle must be of adequatesize to protect the pull cord itself, but not obstructfunction of the coils. Air flow will move the cordand activate the switch. Consult the cold storagecontractor. See Figure 20.

Pull Cord Installation (Continued)

2. Mount the pull cord switch to the ceiling using theswitch mount holes or the mounting plate provided.Wire the switch with standard conduit and water-tight fittings. Locate the switch at least 24� from theconduit penetration through the ceiling or wall.See Figure 21.

WARNING: Drilling of the pull cord switchwill void any and all Warranties of thecomplete door.

3. Locate the pull cord switch away from the door andout of the way of lift trucks and loads. It is mostcommon to locate one pull cord at the interior andone at the exterior of the door opening.

4. Fasten the switch securely to the wall or ceilingand attach the pull cord to the switch arm. Allowthe pull cord to hang straight; do not use guiderings or screw eyes to reposition the cord. Suchitems can hinder operation of the cord or switch.

Install the Wiring5. Install conduit and wire (according to code) from

the pull switch to the Door Header Junction Box.See Figure 22.

6. Remove the covers from the pull cord switchesand junction box.

7. Connect one of the pull switch wires to the Redwire in the junction box. Connect the other wire tothe Brown wire in the junction box. See Figure 23.

8. Connect the second pull cord switch in a similarmanner. Replace the covers on the pull cordswitches and junction box.

Set the Door Close travel limit (Cont.)

1. Jog the door to approximately 1� less than the fullyclosed position. The Door Close limit will be sethere because the Operator will drift the Doorapproximately 1� farther closed upon the first useof the Pull Cord. With the door in this position, theClose Limit lamp (Blue) will be on solid.

2. Before the Close Limit pushbutton lamp goes out(5 seconds), push the Close Limit button. This willset the Door Close travel limit. The Blue lamp willflash for 5 seconds, indicating the Door Closetravel limit is set. See Figure 26.

Test the Door travel limitsWhen both door travel limits have been set, open andclose the door to test the operation.

1. Test run the door by pulling on the Pull Cord,Remote Control, or other operating device.

2. Note the position the door stops in both directions,and readjust the travel limits as necessary.

Adjust the Door Sensing EdgeLocate the plastic Sensitivity Adjusting Screw on theface of the Door Junction Box. Do Not remove thejunction box cover plate. Turn the Screw out todecrease sensitivity or in to increase sensitivity.See Figure 27.

Optimum sensitivity can be achieved using a simpletwo step process.

1. With the power on and the Door open, note theYellow lamp on the Control box. See Figure 26.

• If the Yellow lamp is flashing, turn the AdjustingScrew out until it just stops flashing, plus 1⁄8 turn.

• If the Yellow lamp is off, turn the AdjustingScrew in until it starts flashing.Then, turn theScrew out until the Yellow lamp just stopsflashing, plus 1⁄8 turn. At this point, the Greenlamp may turn on or flash – this is not a problem.

2. Test the sensitivity. Start the Door closing with theJog Close pushbutton. Touch the Sensing Edgewith a tool, to reverse the Door direction and verifythe proper sensitivity. See Figure 28.

This completes the adjustment. If the Door travellimits have already been set, test them and adjust asnecessary.
