DESCRIPTION
CoFold is the ultimate in exterior folding systems and opens up a wealth of new design possibilities. The CoFold System has been designed to maximise the flexibility of a room’s living space, removing barriers and enabling the user to have an indoor/outdoor experience by fully opening up exterior walls. The system which operates with effortless ease combines the benefits of folding doors with the ability to keep out the weather with no corrosion worries. This modern, contemporary feature will increase available living space whilst allowing natural light to envelop the room. System Capacity Maximum leaf height - 3300mm Maximum leaf weight - 100kg Maximum leaf width - 1000mm Leaf thickness - 35-68mm* * For thicker or thinner doors please contact Coastal Technical Team For doors between 35-47mm use an alternative flush bolt Applications Residential and commercial timber exterior folding applications Specially suited to coastal environments made from 316 stainless steel. End folding timber doors folding to one or both sides Standard folding configuration features doors folding outward. Inward folding doors can be used where the doors are not directly exposed to the weather. Premium security features Recognised weather resistance The folding unit is not hinged to post, but is pivoted in the track and floor. All door leaves are of equal width. A swing leaf can be included by incorporating an odd number of leaves. For full weather protection, doors, frame and track should incorporate the seals provided in the CoFold range. Cill and frame construction should be in accordance with the CoFold fixing instructions. Intermediate hangers and hinges are non rebated. www.coastal-group.com

Preparing the opening
Ensure the opening is square and all load bearing areas are suitable for the weight of the system.Take particular care to ensure there issufficient strength in the structure above the opening to take the concentrated weight of the doors, when in the open stacked position.The Cofold system provides +/- 3mm of horizontal and vertical adjustment. Use a plumb line to ensure that the centre line of the trackand the centre line of the channel are offset by 19mm.

Preparing the door leaves
Door leaf width calculation1. Decide how many door leaves you want in the opening.2. Add together all the 3mm clearances required between door leaves and the jambs (there will be one more than the number of door
leaves).This is the total clearance figure.3. Measure the finished opening width (W) and deduct from this the total clearance figure.4. Divide this new figure (finished opening width minus total clearance) by the number of doors to produce the actual door width. (N.B.
all doors with the CoFold system are the same width).
For example: For a 4 door leaf system with a finished opening width of 2345mm the door leaf width would be 2345mm minus (5x3mm)divided by 4 (number of door leaves) = 582.5mm.
Door leaf height calculationLeaf height = finished opening height (see diagram 7) minus 66mm.

Door SealsPrepare the door leaves to accept theAQ63B seal.
Meeting DoorsUse the SF8 set for 2+2 rebated timber doorconfigurations. For all other configurations useSF2L (left hand) or SF2R (right hand) endhanger sets. For kit handing refer to diagram 6.

INSTALLATION
1. Ensure that you have all the required parts. Unpack thecomponents and identify the parts. Lay the parts on theground in the same configuration as they will be wheninstalled. It is recommended that a light smear of generalpurpose grease is applied to all bolts prior to assembly.
2. Cut the track to the required length and pre-drill forfixings in accordance with diagram 17. Please note that theextra fixings are required where the doors stack together.
3. Cut the channel to the required length and fit in thesill. Drill drainage holes (see diagram 1).
4. Remove all the wheel assemblies and pivot block fromthe hanger and pivot bolts, and disassemble top pivotblock assembly.
5. Slide the wheel assemblies and track pivot block intothe track in the correct order, orientation, and positionand fix the track in position. Reassemble top pivot blockassembly (see diagram 18).
6. Remove the bottom pivot assembly and guide rollerassembly (see diagram 19). Disassemble the bottom pivotassembly.
7. For installation, assemble leaves in pairs via the hinges.To improve the ease of installation pre-drill pilot holes forall hinge parts. Fit kits SF1, SF7,SF4 and SF9 (optional) tofirst pair of leaves.Please ensure all 5 screws are fixed per end hinge.
8. Screw the bottom anchor of the bottom pivot assemblyto the base of the channel 11mm from the jamb. Pleasenote, the screw nearest the end of the bottom anchor isclosest to the jamb (see diagram 20). Reassemble the pivotassembly leaving the clamping screws loose (see diagram 24).
9. Suspend pairs of leaves by engaging top pivot andhanger bolts using 5mm allen key supplied (see top ofdiagram 19).
10. Attach the bottom pivot and guide assembly to theirrespective hinges, adjust the bottom pivot side platesposition so that it engages with the hinge bolt.Tightenpivot and guide strap bolts (see diagram 21).
11. Lift the next pair of leaves into position and supporttheir weight by screwing the hanger strap bolt into thehanger wheel assembly and fixing the second and thirdleaves together.
12. Continue this procedure until all leaves are fitted.

Height Adjustment (± 3mm)
1. Close leaves and adjust the door height to achieve anequal gap between the top of the leaves and the track (a9mm gap is recommended). (see diagram 22).
2. Once the adjustment is complete use the allen key totighten the locking hanger grub screw until secure.
Lateral Adjustment
1. With the unit still in the closed position, slide the setof leaves towards the jamb to obtain the desired gapbetween the jamb and the pivot door.A gap of 3mm isrecommended using the adjustment cam. Once inposition tighten the clamp screws. (see diagram 24).
2. Fold the leaves and adjust the bottom side plate usingthe allen key provided so that the gap between the doorand the jamb is the same over the full length of the door.
3. Tighten the two clamping screws to lock the side plateto the bottom anchor.
4. Once the pivot door is in the correct position insertand tighten the locking pivot grub screw from the insideposition. (as shown in diagram 23)
CARE AND MAINTENANCE
To provide years of trouble free operation, it isrecommended that the track is kept free from dirt anddebris. Periodically replace the general purpose grease onall bolts.To prolong the appearance of the exposed hingeparts, it is recommended they are periodically washedwith soap and water. Maintenance is required on allcomponents including stainless steel to validatemanufacturers warranty. For further maintenance detailsplease refer to our website.

1. The Cofold SF9 intermediate pivot set shown in Diagram 1, should be fitted to the pivot door approximately mid way between the SF1 top and bottom pivot assemblies. The SF9 hinge must be positioned on the same centre line as the SF1 top and bottom pivot hinge bodies.
2. Route the door and drill the pilot holes as shown on Diagram 2. Fit the hinge body using the five screws provided.
3. Prepare the frame for the opening by drilling a Ø12mm hole (as shown in Diagram 3), ensuring that the centre point of the hole is 20mm lower than the bottom of the hinge body as shown on Diagram 4. Rebate the frame support plate, if required.
4. Screw the frame support plate on to the opening frame preparation, as shown in Diagram 3.
5. Fit the pivot door into position using the SF1 pivot set.
6. Fit the SF9 cover sleeve on to the SF9 hinge body and drop the hinge strap bolt into position, as shown in Diagram 4.
7. Screw the threaded link arm fully into the frame support plate. The centre of the threaded hole in the link arm should be positioned to receive the strap bolt. Screw the strap bolt in to the link arm until there is a 2mm gap between the head of the strap bolt and the hinge body, as shown in Diagram 4.
8. Adjust the SF9 pivot set to ensure the clearance between the pivot door and the frame is uniform (Diagram 5).
Note: These fitting instructions should be used in conjunction with the Cofold Fitting Instructions
