Fitting

WARNING

Danger of injury as the result of structural modifications Changing or removing functional parts may put important safety components out of action. Uncontrolled door travel could occur and persons or objects may be trapped as a result.

▶ Do not alter or remove any functional parts.

▶ Do not attach any additional components. The torsion springs are precisely matched to the door leaf weight. Additional components may overload the springs.

▶ If equipping the door with an operator, pay attention to the instructions provided by the manufacturers of the door and operator. Only use the original connections of the door manufacturer!

WARNING

The danger of injury as the result of structural modifications Changing or removing functional parts may put important safety components out of action. Uncontrolled door travel could occur and persons or objects may be trapped as a result.

Before fitting the door, the door opening and the building floor must be completely finished.
Observe the following during fitting:
Establish a secure connection with the building structure.
Check that the fixing materials supplied are suitable for the given structural conditions.
Do not fasten the door system to support structural members unless you have obtained the prior approval of the structural engineer.
Ensure adequate water run-off in the area of the bottom seal and the frame parts, otherwise there is a danger of corrosion (see Technical Manual).
Ensure sufficient drying and ventilation in the building, otherwise, there is a danger of corrosion.
The door must be effectively protected before carrying out plastering and paintwork, as splashes of mortar, cement, plaster, paint etc. can damage the door surface.
Protect the door from caustic, aggressive substances, e.g. nitrous reactions from stones or mortar, acids, alkali solutions, de-icing salt, aggressive paints or sealants. Failure to do so could lead to corrosion.
To ensure simple and secure fitting, please follow the work steps listed in the illustrated section.

Tensioning the springs

WARNING

The danger of injury due to high torques
Springs are under high torque stress and may discharge high forces if they are not secured during tensioning.

Fix the door leaf to prevent movement before tensioning the springs.

The number of tensioning revolutions specified on the type plate is an approximate value only.
When the springs are tensioned correctly, the moving door leaf has a slight tendency to pull upwards.

Each time the door is serviced, the tension of the springs should be checked and, if necessary, subsequently re-adjusted.
Before putting the door into operation for the first time, inspect the door according to the chapter Inspection and Maintenance!

Operation

Operating the door

WARNING
The danger of injury during door travel
The sectional door closes to the bottom vertically; persons or objects may be trapped.

When in operation, make sure that neither persons, children in particular, nor objects are located within the door’s area of travel.
Always keep the opening area of the door clear.
Do not operate the door in strong winds.
The door must only be operated by suitably instructed persons. If the sectional door is competently fitted and inspected, it can be easily moved and operated.

Manually operated doors

WARNING
Danger of injury due to improper operation
Persons or objects may be trapped if the door is operated improperly.

Only open and close the door using the supplied operating elements; these ensure a controlled, smooth action.
When closing the door, make sure that the latches engage fully and correctly.

Power-driven doors
The automation of a sectional door requires that special safety regulations be observed. Consult your supplier.

Locking and unlocking
The door is not locked when closed with the grip handle. This is done by using the key or locking lever on the lock.

From outside:

Turn the key 360°
To unlock: turn the key left To lock: turn the key right
From inside:
Slide the locking lever on the lock To unlock: slide it upwards
To lock: slide it downwards

Cleaning and Care

ATTENTION

Scratches on the panes due to improper cleaning Rubbing the panes causes scratches.

Dirt and dust particles must first be thoroughly rinsed off with water. If necessary, only wash with water, a pH-neutral household detergent and a soft, clean cloth.

Clear water is sufficient for cleaning and care. Use warm water together with a neutral, non-abrasive cleaning agent (household detergent, pH value 7) if more heavily soiled. To preserve the surface characteristics, regular cleaning must be carried out at least every 3 months (outside of door, seals). The slide area behind the side seals must be kept permanently clean and able to slide.
A variety of environmental influences (e.g. maritime climate, acids, road salt, air pollutants, paint damage) may make additional protective coating necessary (see Surface on page 7).
Annual maintenance of the timber surface with the ADLER Windoor Care Set (contents: ADLER Top-Cleaner and ADLER Top-Care) is recommended

Inspection and Maintenance

Inspections and maintenance

WARNING

Danger of injury due to defective safety components Important safety components may fail or become defective if not sufficiently inspected and maintained.

Danger of injury due to defective safety components Important safety components may fail or become defective if not sufficiently inspected and maintained.
The following inspection and maintenance tasks must be carried out by a specialist in accordance with these instructions, before initial operation and at least once a year.

Inspect all load-bearing components

WARNING

The danger of injury due to high cable tension and high torques
Cables and springs are under high tension and torques. Damaged cables or springs may also cause serious injuries.

Fix the door leaf to prevent uncontrolled movement before exchanging damaged cables or springs.
Be particularly careful when exchanging damaged cables or springs.
Check load carriers (cables, springs, tracks, supports) and safety devices for breakage and damage, replacing any damaged components as necessary.

Spring safety device

Check the effectiveness of the detent pawl and the secure seat of the locking gear (see Fig. 14.3 Spring safety device).

Weight counterbalance

WARNING

The danger of injury due to uncontrolled door drops
If the counterbalance has not been properly adjusted, this may result in an uncontrolled door drop, which could trap persons or objects.

Retention the torsion springs.

High torque
Springs are under high torque stress and may discharge high forces if they are not secured during tensioning.

Fix the door leaf to prevent uncontrolled movement before adjusting the torsion spring shaft.

Check the counterbalance of the door leaf

Manually open the door halfway. The door should be able to hold this position.

If the door moves substantially downwards:

Retention the torsion springs.

Fixing points

Check all the fixing points on the door and the building structure and make sure that all the fastenings are securely seated and, if necessary, retighten.

Rollers and tracks
When the door is closed, the rollers must be easy to turn.

Just rollers if necessary. Observe the operator fitting notes; they contain details on roller adjustment.
Clean tracks, if necessary, do not grease!

Hinges and roller holders

Oil hinges and roller holders.

Locking cylinders

ATTENTION

Damage to the locking cylinders due to unsuitable cleaning products Locking cylinders may not be cleaned with agents containing oil or be oiled.

Only use specialized care products.
Do not use oil or graphite.

Seals

Check for damage, deformations and completeness. If necessary, replace.

Malfunctions and Troubleshooting

WARNING

Danger of injury due to uncontrolled door movement
If the door malfunctions, uncontrolled door movements may trap persons or objects.

In the event of a door failure (sluggish operation or other malfunctions), a specialist must be commissioned immediately for the inspection/repair work.

Once the spring safety device has been activated, the door leaf weight is no longer balanced. Further operation of the door is no longer possible.

Spring safety device

Once the spring safety device has been activated, hold the door leaf using a suitable auxiliary tool, then move the spring shaft with a tensioning spindle so that the capture pawl can be released and secured with the security pin.
afterward, let the door leaf down, release the springs and replace the one that has broken.

Surface

Timber is a natural product. Durability depends on factors such as:

Weathering
Constructive timber protection
Mechanical load
Colour

Maintenance is required for long durability. Annual maintenance is recommended.

Do not use dark glazes in direct sunlight.
Always keep the garage well ventilated.

Purpose of coating

The coating applied at the factory is a water-based, thin-layer wood preservative based on acrylic and alkyd resin dispersion paints. The wood preservative has high blocking resistance and good weather resistance. The degradation caused by weathering is uniform.

Cracks resulting from shrinkage are unavoidable due to weather conditions.

The extent of these shrinkage cracks depends on the air humidity. Shrinkage cracks, colour deviations and dimensional tolerances are not defects in terms of the DIN or TÜV regulations. These properties do not impair the strength, durability and safety of the product.
Protect the timber door against environmental effects with a pigmented, open- pore glaze coating.
If a glaze coating is not applied at the factory, the glaze coating must be applied on-site.

First coating
The first coating must be applied before fitting.
The moisture content of the wood must be < 15%. After every intermediate coat, you must sand the surface once it has finished drying.
Before weathering for the first time, 2 – 3 layers must be painted on the inside and outside.

Do not use any paints that seal the surfaces. Such paints prevent uniform moisture exchange.
An insufficient coating increases the risk of cracks in the timber.

Coating recommendation

High-quality, water-based glazes are suitable for coating exterior components with limited dimensional accuracy.
Test sample surfaces at discrete spots. Observe the application instructions provided by the manufacturer.
Maintenance and follow-up treatment of coating performed at the factory and on-site

In order to maintain the protection, you need to check the surface once a year and touch it up professionally if necessary. Remove any dirt from the surface first.
Work the surface in the direction of the grain with 220/240 grit sandpaper or sanding fleece. Remove the dust thoroughly with a brush or broom.
The subsurface must be dry, clean and must have a good load-bearing capacity. Remove grease, wax, silicone, resin and separating substances. Check whether the surface is suitable for the coating.

Observe the application instructions on the product.
