Motor unit positioning |
|
|
|
|
| 1) The motor unit can be installed both above and below the window; it is important to keep the correct distance between glass rim and motor axle hole (dimension C) stated when ordering the unit, as all units are custom made. |
 |
|
|
|
| 2) Drill a Ø20.5mm hole for the motor axle perpendicular to the glass surface. If necessary adjust the motor mounting surface with wedge packings. |
 |
|
|
|
| 3) The motor unit can be positioned at any angle around its axle. |

Arm installation |
|
| The drawing 1B below shows the cross section of a standard window and the correct working position of the arm. The other drawings show cross sections of special windows with the following tolerances: |
P max = 25mm G max = 15mm F max = 40mm |
| If dimensions P, G and F exceed the specified values, it is necessary to proceed as follows: | |
 |
|
|
Draw. 2B Window with very large outside frame: - use a hardwood block to compensate P dimension; use a bent arm if P exceeds 40mm. Draw. 3B Window with protruding glass above tolerance: - use a hardwood block to compensate G dimension. Draw. 4B Window with recessed glass above tolerance: - use a bent arm if F exceeds 40mm |
|
| The above dimensions are requested when ordering the arm, dictating whether a bent arm or a prolonged axle are necessary. | |
