Installation of the DICTAMAT AC 900-21

The door operator can be mounted to the rail either in the open or

closed positon of the door/gate. It is fixed with the wall bracket to

the wall above or beside the rail. The operator weighs up to

40 kg (depending on the version). In addition you also have to

take into consideration the forces which have to be transfered to

the door. It is very important a strong enough fixing is

provided on site.

Fix the wall bracket to the wall (see drawing for drilling pattern).

Fix the U-bracket to the wall bracket. Screw the door operator from

below to the U-bracket. The operator can be positioned due to the

oblong holes in the U-bracket. Align the operator parallel to the

rail and then tighten the two attachment screws (SW17) from

below until the door operator cannot move any more.

Unscrew the cover of the driving wheel and of the belt coming-off

prevention device respectively.

Fix the idler pulley at the opposite side of the rail to the wall

bracket and this to the wall. Align the idler pulley provisionally

with the help of the oblong holes in the bracket and tighten the

screws (SW17).

Height: depends on whether the upper or lower belt/chain shall

be fitted. Measure the distance between the lower edge of the rail

and the belt/chain on the operator. This measure determines the

upper edge of the belt/chain fixing device. Later the fixing device

can exactly be aligned by means of the oblong holes in the

mounting bracket.

Screw the belt/chain fixing device to the door.

Then completely open and close the door once by hand.

Fix one end of the toothed belt/chain to one side of the clamping

plate of the belt/chain fixing device.

Guide the other end of the toothed belt/chain over the idler pulley

(see ill.1) and driving wheel of the DICTATMAT door operator (or

the other way round) to the other side of the belt fixing device.
