Configuració i instal·lació
Proper installation is crucial for the security and functionality of your EVVA Euro Double Cylinder. It is recommended that installation be performed by a qualified locksmith or experienced individual.
- Preparació: Ensure the door is prepared with a standard Euro profile cylinder cutout. Measure the existing cylinder to confirm the 41/41 NP (82mm total length) is the correct size for your door thickness.
- Remove Old Cylinder (if applicable): Unscrew the retaining screw located on the door edge, typically below the latch. Insert a key into the existing cylinder and turn it slightly (about 15-20 degrees) to align the cam with the cylinder body, allowing it to slide out.
- Inseriu un cilindre nou: Insert one of the supplied keys into the new EVVA cylinder. Turn the key slightly to align the cam with the cylinder body. Slide the new cylinder into the door's mortise lock until it is flush with the door face.
- Cilindre segur: Re-insert and tighten the retaining screw on the door edge. Do not overtighten.
- Prova de funcionament: With the door open, insert a key from both sides and turn it to ensure smooth operation of the lock mechanism. Check that the key can be fully inserted and removed without obstruction.
Instruccions de funcionament
The EVVA Euro Double Cylinder operates with a key from both the interior and exterior sides of the door.
- Bloqueig: Insert the key fully into the keyway. Turn the key clockwise (or counter-clockwise, depending on the lock mechanism) until the bolt is fully extended and the door is secured. Remove the key.
- Desbloqueig: Insert the key fully into the keyway. Turn the key counter-clockwise (or clockwise) until the bolt is fully retracted and the door is unlocked. Remove the key.
- Duplicació de claus: This cylinder range allows for unrestricted key duplication. Keys can be duplicated by a qualified locksmith using standard key cutting equipment.
Manteniment
Regular maintenance ensures the longevity and smooth operation of your lock cylinder.
- Lubricació: Periodically (e.g., once a year), apply a small amount of graphite-based lubricant or a specialized lock lubricant into the keyway. Avoid using oil-based lubricants as they can attract dust and debris, leading to clogging.
- Neteja: Keep the keyway free from dust and debris. Use a soft, dry cloth to wipe the exterior of the cylinder. Do not use abrasive cleaners or solvents.
- Atenció clau: Avoid bending or damaging the keys. Store spare keys in a secure location.
