- Assemblaggio del braccio: Connects the door closer to the door frame or door.
- Adjustment Valves: Two independent valves for controlling closing speed and final latching.
- Mounting Plate/Template: For accurate positioning during installation.
- Viti di fissaggio: For secure attachment.
4. Configurazione e installazione
The CISA Serie 604 door closer is designed for quick installation and can be mounted on both right-hand and left-hand doors, for both pull-side and push-side applications. A mounting template is provided to simplify the process.
4.1. Controlli pre-installazione
- Verify the door weight and width are within the specified limits (max 85 kg, max 1100 mm).
- Determine the mounting position (door or frame) and orientation (pull-side or push-side) based on your door type and desired opening angle.
- Ensure the mounting surface is strong enough to support the door closer.
4.2. Passaggi di montaggio
- Posizionamento: Use the provided mounting template to mark the drilling points on the door or door frame.
- Perforazione: Praticare dei fori pilota nelle posizioni contrassegnate.
- Collegare il corpo principale: Securely fasten the main body of the door closer using the supplied fixing screws.
- Montare il braccio: Attach the arm assembly to the door closer and the door frame/door, following the specific instructions for your chosen mounting type (pull-side or push-side). Ensure all connections are tight.

5. Istruzioni per l'uso e regolazioni
The CISA Serie 604 door closer allows for independent adjustment of two key functions: closing speed and final latching action. These adjustments are crucial for optimal door performance and safety.
5.1. Adjustment Valves
The door closer features two adjustment valves, typically labeled '1' and '2' or similar, as shown in Figure 1. These valves control different phases of the door's closing cycle:
- Valve 1 (Closing Speed): Controls the speed of the door from its fully open position until approximately 15 degrees from closure. Turning the valve clockwise decreases the speed (slower closing), and counter-clockwise increases the speed (faster closing).
- Valve 2 (Final Latching Action / Backcheck): Controls the speed of the door for the final 15 degrees of closure, ensuring the door latches securely without slamming. It can also provide a backcheck function to prevent the door from opening too quickly or forcefully. Turning clockwise decreases the latching speed/increases backcheck, counter-clockwise increases latching speed/decreases backcheck.

Figura 3: This diagram illustrates the two distinct adjustment sectors. The green sector (up to 80 degrees) represents the main closing speed, while the red sector (final 15 degrees) indicates the final latching action, both independently adjustable.
5.2. Making Adjustments
- Use a suitable screwdriver to turn the adjustment valves.
- Make small adjustments (quarter turns) at a time and test the door's closing action after each adjustment.
- Do not overtighten or loosen the valves excessively, as this can damage the hydraulic mechanism.
- Aim for a smooth, controlled closing action that allows the door to latch without excessive force or speed.
6. Manutenzione
The CISA Serie 604 door closer is designed for long-term, maintenance-free operation. However, periodic checks can help ensure its continued performance and extend its lifespan.
- Ispezione annuale: Annually inspect the door closer and its mounting screws for any signs of loosening, wear, or damage.
- Pulizia: Keep the door closer clean from dust and debris. Use a soft, damp panno per la pulizia. Evitare detergenti abrasivi o solventi.
- Lubrificazione: No internal lubrication is required. Do not attempt to lubricate any part of the hydraulic mechanism.
- Assemblaggio del braccio: Check the arm assembly for any bending or damage. Ensure all pivot points move freely without excessive play.
If any significant wear or damage is observed, contact a qualified technician for inspection and repair or replacement.
7. Risoluzione Dei Problemi
This section addresses common issues you might encounter with your CISA Serie 604 door closer.
| Problema | Possibile causa | Soluzione |
|---|---|---|
| La porta sbatte | Closing speed or final latching speed is too fast. | Adjust Valve 1 (closing speed) and/or Valve 2 (final latching) clockwise in small increments until desired speed is achieved. |
| La porta si chiude troppo lentamente | Closing speed is too slow. | Adjust Valve 1 (closing speed) counter-clockwise in small increments. |
| Door does not latch properly | Final latching speed is too slow or insufficient. | Adjust Valve 2 (final latching) counter-clockwise in small increments to increase latching force/speed. |
| Perdita di olio | Guarnizioni o componenti interni danneggiati. | This indicates a serious issue. The unit cannot be repaired by the user. Contact a qualified technician or replace the unit. |
| Door closer makes unusual noises | Loose mounting screws or damaged internal components. | Check and tighten all mounting screws. If noise persists, contact a qualified technician. |
