General instructions

DF 88 offers additional protection from unauthorised intruders in your rooms. The lock is suitable for dormer windows made of wood, metal and PVC where lock body and locking case have to be fitted at an angle of 90° to each other (fig. 1). Some dormer windows are built like a normal window. In this case, FTS 88 can be used.

Caution! Some dormer window types have a locked cleaning setting at 180°. After fitting DF 88, it may happen that this locked setting is no longer possible.
Recommendation: Fit DF 88 as low as possible to achieve a maximum turning angle.
Optimum protection can be achieved by proceeding according to these installation and operation instructions. To prevent the risk of overtightening, the fastening screws should by screwed in using a suitable tool and tightened by hand. Only use ABUS fastening material.
The manufacturer does not assume any liability for possible injuries or damages caused during installation and/or by incorrect handling!
One entrance possibility of the whole object must be accessible with a key from the outside.

Possible use for DF 88

DF 88 is suitable for dormer windows which open to the outside and which are hinged at the top or in the middle.
DF 88 is always mounted to the inside, with the locking case on the window casement and the lock case on the frame.
From an inner frame width of approx. 50 cm, two DF 88 should be fitted, on the right or left, on the side or bottom.

When only one lock is fitted, it should be positioned on the right side of the window.

Before installation, please check the setting of the window. If necessary, readjust the fittings so that the window opens and closes perfectly.
Also check whether your window complies with the minimum dimensions shown in fig. 1.
The depths of the drilled holes and screw lengths must be adjusted to the local conditions.
Avoid the drill or screws from coming out at the back! Possibly work with drill stopper or shorten the existing screws.
When drilling, do not damage any moving parts, seals or glass panes.
