2 Section 1 Delivery/Storing On Site/Handling l SpeedZip is factory or on-site manufactured. l Straight SpeedZip bundles are a maximum 1 tonne, 2 No. sheets nestled and then and placed face to face, banded with steel bands around timber frames where appropriate. l Curved SpeedZip is bundled with all sheets the same way up, on trestles and the correct way up for hoisting direct to the roof. l Packs may be separated by wood fibre dunnage load separators. l Packing sheets are marked as packing sheets. l Some paint finishes have protective strippable film. l If storing sheets for any length of time, keep clear of the ground and stack sheets to slight fall to shed rainwater. l Cover with waterproof sheeting and support at 2m intervals. If water has accumulated on the sheets, ensure it is removed before hoisting. l Note: Stucco aluminium will discolour (oxidise) if exposed to strong alkalis i.e. cement, mortar, lime etc, or if left exposed in the pack for long. 1

l Ensure frame will carry any point loading applied. l Load roof over main supports. l Roof sheet bundles are 1 tonne max. WalkLiner 1020/32 packs are 1.5 tonne max.

3 l Ensure frame will carry any point loading applied. l Load roof over main supports. l Roof sheet bundles are 1 tonne max. WalkLiner 1020/32 packs are 1.5 tonne max. l Ensure that all the under ribs are facing in the direction of lay. This will prevent unnecessary handling and turning around on the roof. The direction of lay should always be into the prevailing wind where possible. Note: Capillary groove in top of rib 2

l Packs under 7.5m can be lifted with care using a site fork lift. l Packs 7.5m to 13.6m can be lifted using 2 No. web slings with the sling angle > 45, subject to the crane company s advice.

4 l Packs under 7.5m can be lifted with care using a site fork lift. l Packs 7.5m to 13.6m can be lifted using 2 No. web slings with the sling angle > 45, subject to the crane company s advice. l Lifting beams are available to hire for bundles over 13.6m long. l Beams are provided subject to costs and terms contained within the quote. l Where possible return the beams and slings with the delivery lorry. 3

5 Section 2 Installation 1. Establish a straight line at the verge, 90 degrees to the eaves line. 2. Install the first line of halter brackets to this line. Always use 2 No. stainless steel fixings provided per halter, but note that the gable hook is also secured with one of these screws. 3. Use the gauging template to set out SpeedZip halter brackets. Halter brackets have an integral EPDM pad under the base. Use the correct gauging template for the profile, check for creep in gauging. The gauging should be:- 408mm +1/-2mm. 4. Install the ridge support zed under the halter brackets at the ridge only. Isolate galvanised steel from aluminium with self adhesive tape. GGauging Template 4

6 5. Install the self adhesive eaves filler strip. 6. Install the first sheet, ensuring that the under rib clicks into the halters. 7. Use the hand tongs to squeeze the over rib for 300mm at each end of the sheet before mechanically zipping up the whole sheet. This must be done. Protect painted finishes from tongs by using cloth or similar. 5

7 8. Then zip up the over rib using the zipping tool. Use the dead man switch. 9. Install the fixed point fixing at the specified position. A sheet must have one and only one fixed point. Use 4.8x12m aluminium rivets or specified fixed point fixing. 10. Install the next sheet. Ensure that the over rib sits tight on the under rib and zip-up the seam. Always zip-up as you go, and use hand tongs for the first and last 300mm. Avoid walking on the SpeedZip sheets as much as possible. When working on a detail (e.g. ridge), work off secure boarding. Protect roof access positions. Only install as much insulation as can be covered in one SpeedZip installation session, keeping the insulation dry. Walk on ribs if possible to minimise risk of damage to pans. 11. To unzip a profile use the unzipping attachment at the front of the zipper. Note that once unzipped, the seam may not re-seam fully. In this instance, and where ever seaming is not sufficient, use omega cover strips. Omega cover strip 6

8 12. Omega cover strips - for use with rooflights or as (11) above, use an omega zipping tool plus omega tongs. 13. At ridge, turn up pan of sheet to vertical, install filler and ridge dam. Fix ridge dam to seam of SpeedZip using 4.8mm diameter rivets. Fix ridge to ridge dam at 200mm nominal centres. 14. At eaves, install angle strip under eaves. Secure with 2 No. aluminium rivets per pan. At pitches <10, form eaves turndown. Note: Isolate aluminium flashings from galvanised steel spacer. Ensure that insulation fills cavity, under slight compression 7

9 SpeedZip tool care The tools are provided under hire and included in the tool box are: l SpeedZip zipper l Deadman switch and lead l Hand tongs l Turn up / turn down tool The tools provided have been factory serviced, checked and set. It is the customers duty to keep the tools in good condition and to return them in good condition, in the tool box, promptly when no longer needed. Damage requiring repair will be charged for. Zipper The zipper tooling (the wheels under the machine) should be nylon for painted roof sheet and stainless steel for stucco aluminium. l Tooling should be regularly inspected and kept clean and burr free. l Remove any accumulated debris or nicks using emery cloth and white spirit, as appropriate. l The integrity of wiring should be visually checked. l Tools can be set by the two 19mm side bolts to give a sheet rib head diameter of about 20-22mm. l If tooling is changed over, use a 19mm socket plus extension, retaining all washers. Special tooling is available for zipping omega strips. Hand Tongs l Keep hand tongs clean. l Always use a cloth or other material in tongs to protect painted sheets. l Always use tongs to squeeze ribs at each end before setting the zipper over the rib. Turn up/ Turn down tool Keep clean and clear of debris. 8
