A Safety & Installation

IMPORTANT! Please read all these installation instructions before starting to install your loft ladder.
The ladder should be high enough to allow you to climb up into the loft without exceeding the maximum permitted safe working height. The ladder must bear a load corresponding to the weight of the fitter plus the weight of the loft ladder.
Do not use the ladder as an access passage during building or renovation work. Do not use the ladder if the ceiling height exceeds the maximum ceiling height stated in the installation instructions or on the product label.
For safety’s sake, always face the ladder when climbing up and down and grip at least one string of the ladder. The ladder must be used only by one person at a time.
Do not use the ladder if it is faulty or damaged. The springs are very taut. Take care when adjusting springs. Only adjust the spring mechanism when the ladder is folded (i.e. the springs are under least tension). Great care should be taken when removing springs. If the ladder is delivered unassembled, read the assembly instructions carefully before assembling and installing the ladder.
The ladder is tested to 150 kg (maximum load). A load in excess of 150 kg may cause damage to the ladder and constitutes a risk of personal injury.
NB! Lubricate all moving metal parts with oil immediately after assembly. Parts must subsequently be lubricated at least once a year.

01 Fitters, tools and materials:
We recommend that 2 fitters install the loft ladder together. One fitter must be strong enough to lift the loft ladder to the ceiling (as the loft ladder weighs up to 28 kg (EAN: 3663602522508 ) / 28.7 kg (EAN: 3663602548140), depending on model).

02 Installation instructions:

To ensure that the product is assembled and fitted correctly, these instructions should be followed carefully. If you have any difficulties, contact an expert for installation advice.

WARNING: DO NOT DISMANTLE the loft ladder once it has been assembled.

NB! For models in which the ladder is fixed to the trapdoor. If, during installation, you wish to detach the ladder to reduce the weight of the loft ladder, loosen the screws between the metal bracket and the ladder itself. Do not loosen the screws on the trapdoor as these can easily be over tightened when reassembled. An over tightened screw may lose its grip on the timber and, in serious cases, fall out.

Positioning the loft ladder:
Wear gloves when removing insulation material. Check that the area selected for positioning the ladder is unencumbered by electrical wiring, water pipes, heating/cooling pipes, etc. If necessary, get a qualified craftsman to remove such encumbrances. Make sure that there is sufficient clearance (distance A) for the ladder to rest on the floor. Make sure that there is sufficient space for the ladder to fold out to its full length (B) (see figure 1). For two- section models, make sure that there is sufficient swing space. For specific measurements and adjustment options, see the assembly instructions supplied with the product.

03 To make opening in ceiling:
We recommend that you wear goggles and mask for protection from falling dust and other particles from the loft. Remove all items of furniture from the work area. Cover the floor. Frame and cut the opening through plaster/other ceiling material (see table 1). This allows space for spacer blocks and ensures that

A Safety & Installation

the loft ladder is fitted perpendicularly. If the loft ladder cannot be fitted in the normal way, i.e. parallel with the ceiling joists, contact a qualified craftsman for advice. Figures 2, 3 and 4 show how to frame the ceiling opening. If you fit the loft ladder parallel to the existing ceiling joints, only single ceiling joists and single transverse joists are required. If you fit the loft ladder at right angles to the joists, you will need to make double transverse joists of the same size as the existing ceiling joists.

WARNING: If the ceiling joists are made in a material other than timber, e.g. steel, contact a qualified craftsman. Never saw through a load-bearing joist without advice from a qualified craftsman. Take great care when sawing ceiling joists. For safety’s sake, if there is no loft flooring, lay planks across the ceiling joists to allow safe passage in the loft during installation.

04 Fitting temporary supports:

To keep the loft ladder in place in the ceiling opening during installation, you are advised to fit temporary supports. If the trapdoor will be clad, the loft ladder must be fitted as many mm higher in the opening as the thickness of the cladding. Cladding material must not weigh more than 6 kg per m². Cladding material must not be more than 12 mm thick. We recommend that the cladding is affixed using construction adhesive.

Figure 5

WARNING: It is important that cladding is fitted firmly and correctly. When affixing cladding, the ladder must NOT be loaded.

05 Attaching the loft ladder:

One fitter goes up into the loft room, taking all the tools he needs. The other fitter remains below.

Lift the ladder up into the loft. Before lowering the loft ladder into the opening from above, attach 2 supporting planks under the ceiling opening. The loft ladder rests on these supports (see figure 5). Fold the ladder so that the frame can be attached to the ceiling opening. Make sure that the loft ladder is level and perpendicular. Attach loft ladder with adequate screws, allow at least half the total screw length to penetrate the support joists, specified within Assembly Step `05′ on page 5 (3 on long side and 2 at each end). Don’t forget to attach blocks on the back of the fixing points (see figure 6). When the loft ladder is firmly attached, remove supports.

WARNING: DO NOT use the loft ladder before it is firmly attached to the opening and adjusted to the correct ceiling height.

Vapour barrier: When the loft ladder is firmly attached to the deck, the vapour barrier must be attached in the correct way. The space between the loft ladder and the joist construction must be well insulated to avoid thermal bridges.

06 Adjusting to correct ceiling height:

Refer to step 9, 10 and 11 from assembly instructions for detail on adjusting the length of the ladder.

WARNING: DO NOT SHORTEN THE LADDER TOO MUCH. If the ladder is too short, it may unexpectedly fold up during use, thus risking serious personal injury. To check that the ladder is the correct length, unfold it to its full length. All sections of the ladder must be aligned perfectly with no gaps, and both strings must rest flat on the floor (see figure 8).

Figure 7 Figure 8

DO NOT use the ladder if all sections of the ladder are not aligned. If the ladder is too long, shorten the strings once more. If the ladder is too short, order a new lower section from your dealer. Do NOT allow the ladder to rest on a box, blocks, platform or similar. Such constructions are unsafe and unstable, and do not provide appropriate permanent support for the ladder.

07 How to use the ladder:

Figure 9A Figure 9B Figure 9C

The following drawings show how to use the loft ladder safely (see figure 9).

NOTE: If your building construction differs from installation guide above, consult an expert.
WARNING: Never modify the product. The manufacturer accepts no liability whatsoever for personal injury or damage caused to the building or parts thereof by a product, whose construction has been modified.
