Mercor Light&Vent Smoke Vent MCR Prolight NG-A

There are two methods for adjusting the locks installed in the vent. The locks adjustment order is irrelevant, since they operate independently.

Method 1 – adjusting the lock installation height:

The screws that secure the lock and are responsible for adjustment are shown in Fig. 42 – marked with the number "2". Adjustment may be performed within a range of about 5 mm.

After correcting the height (if necessary), tighten the screws and secure the lock from unintended moving using a counter self-drilling screw – marked as item "1" on Fig. 42.

Method 2 – adjusting the electromagnet anchor position:

After closing the anchor, its entire surface should adhere to the electromagnet. If a situation shown on Fig. 46, occurs that the anchor does not close completely, adjust it so that the surfaces of the electromagnet and the anchor lie parallel towards each other when closed.

If the lock (or both locks) do not function properly, the reason may be their wrong adjustment. In such case, the adjustment activities described above must be performed.;

Warning: This procedure requires trained personnel with PPE!

Is the vent leaf joined with the actuator through a hook locking device?

If not, the vent leaf is directly joined and does not require adjustment.

Is the hook locking device locked on a T-shaped bolt?

If not, lock the hook locking device on a T-shaped bolt.

Is the eye bolt screwed into the piston rod/spindle of the actuator?

If not, screw the eye bolt into the piston rod/spindle of the actuator.

Is the play of the vent leaf reduced?

If not, reduce the play by adjusting the T-bolt and the eye bolt.
