1. Introducció
The Danfoss KP-15 060-1264 is an automatic reset high-low pressure switch designed for regulating pressure in refrigeration and air conditioning systems. It ensures safe operation by monitoring pressure levels and activating or deactivating components as needed. This manual provides essential information for the proper installation, operation, and maintenance of the device.
2. Instruccions de seguretat
Always observe general safety precautions during installation and servicing. Only qualified personnel should install, service, or repair this equipment. Disconnect power before servicing. Ensure all electrical connections comply with local codes and regulations.
3. Configuració i instal·lació
Proper installation is crucial for the reliable operation of the KP-15 pressure switch.
3.1 Muntatge
Mount the pressure switch in a location free from excessive vibration and moisture. Ensure easy access for wiring and pressure line connections. The switch can be mounted in any position, but vertical mounting with the pressure connections downwards is generally recommended to prevent accumulation of oil or moisture.
3.2 Pressure Line Connection
Connect the pressure lines to the appropriate ports on the switch. Ensure a tight, leak-free connection using suitable fittings and sealants. The KP-15 features two pressure connections for high and low pressure monitoring.
3.3 Cablejat elèctric
Refer to the wiring diagram provided inside the switch cover. Connect the electrical supply and control circuits according to the system requirements. Ensure proper grounding. The switch is rated for 15 Amperes.
3.4 Ajust de pressió
Adjust the cut-in and cut-out pressure settings using the adjustment screws located under the cover. The KP-15 is an automatic reset type, meaning it will automatically reset once the pressure returns to the set limits.

4. Instruccions de funcionament
The Danfoss KP-15 operates in an ON-OFF mode, automatically responding to pressure changes within the system.
4.1 Funcionament automàtic
Once installed and set, the pressure switch will continuously monitor the system pressure. If the pressure exceeds the high-pressure set point or falls below the low-pressure set point, the switch will activate its contacts to control the connected equipment (e.g., compressor, fan).
4.2 Funció de reinici
As an automatic reset switch, the KP-15 will automatically return to its normal operating state once the system pressure returns to within the acceptable range, without requiring manual intervention.
5. Manteniment
Regular maintenance ensures the longevity and reliability of your pressure switch.
- Inspecció visual: Periodically inspect the switch for any signs of physical damage, corrosion, or loose connections.
- Neteja: Mantingueu l'exterior de l'interruptor net i lliure de pols i deixalles. No utilitzeu productes químics agressius.
- Comprovació de la connexió: Ensure all electrical and pressure line connections remain secure and leak-free.
- Prova de funcionalitat: If possible and safe, periodically test the switch's functionality by simulating pressure conditions to verify its cut-in and cut-out points.
6. Solució De Problemes
This section addresses common issues you might encounter with the KP-15 pressure switch.
| Problema | Causa possible | Solució |
|---|---|---|
| Switch not activating at set pressure | Incorrect pressure settings; Clogged pressure line; Faulty switch. | Verify and adjust settings; Check and clear pressure lines; Test switch continuity (if qualified). |
| Switch continuously cycles | Pressure fluctuations in the system; Differential setting too narrow. | Investigate system pressure stability; Adjust differential setting to a wider range. |
| No electrical response | No power supply; Loose wiring; Blown fuse/breaker. | Check power supply; Inspect and secure wiring; Check and replace fuse/reset breaker. |
