4. ഇൻസ്റ്റലേഷൻ

Follow these steps for proper installation of the DB 10 Pressure Switch:

1. മൗണ്ടിംഗ് ലൊക്കേഷൻ തിരഞ്ഞെടുക്കുക: Select a location for the pressure switch that is easily accessible and close to the ductwork or system it will monitor. The switch should be mounted vertically with the pressure port facing upwards or horizontally.
2. സ്വിച്ച് മൌണ്ട് ചെയ്യുക: Use the provided mounting hardware to securely attach the pressure switch to a stable surface.
3. Prepare Duct Connection: Drill a small hole (typically 1/4 inch) into the ductwork where pressure changes are most significant. For applications like dryer booster fans, it is often recommended to drill the hole just before an elbow or a backdraft damper to ensure sufficient pressure buildup for reliable activation.
4. ട്യൂബുകൾ ബന്ധിപ്പിക്കുക: Insert one end of the NPT tubing into the pressure port on the switch. Secure the other end of the tubing into the drilled hole in the ductwork using the provided grommet to create an airtight seal. Ensure the tubing is not kinked or obstructed.
5. ഇലക്ട്രിക്കൽ വയറിംഗ്: The DB 10 switch is designed for 115-120 Volt AC supply. It features a Normally Closed (NC) contact type. Connect the electrical wires using the provided wire nuts according to the wiring diagram specific to your application. Ensure all connections are tight and insulated. Consult a qualified electrician if you are unsure about the wiring process.
6. കണക്ഷനുകൾ പരിശോധിക്കുക: Double-check all mechanical and electrical connections before restoring power.

5. ഓപ്പറേഷൻ

The Fantech DB 10 Pressure Switch operates automatically based on pressure differentials. When the system it monitors (e.g., a dryer or ventilation fan) begins operation, it creates a pressure change within the ductwork. Once this pressure change reaches the switch's activation threshold, the switch will close its contacts, thereby activating the connected device (e.g., a booster fan). The integral delay function ensures that the switch does not react to momentary pressure fluctuations, providing stable and consistent operation. When the system stops, the pressure drops, and after a short delay, the switch will open its contacts, deactivating the connected device.

6. പരിപാലനം

The DB 10 Pressure Switch is designed for minimal maintenance. However, periodic checks can ensure its longevity and reliable performance:

• ട്യൂബിംഗ് പരിശോധിക്കുക: Periodically check the NPT tubing for any kinks, cracks, or blockages that could affect pressure sensing. Ensure it remains securely connected to both the switch and the duct.
• ഇലക്ട്രിക്കൽ കണക്ഷനുകൾ പരിശോധിക്കുക: Ensure all wire nuts and electrical connections remain tight and free from corrosion.
• വൃത്തിയുള്ള പുറം: Keep the exterior of the switch clean and free from dust or debris. Do not use harsh chemicals.
• പ്രവർത്തനം സ്ഥിരീകരിക്കുക: Occasionally verify that the switch activates and deactivates as expected with the operation of the connected system.

7. പ്രശ്‌നപരിഹാരം

If you encounter issues with your DB 10 Pressure Switch, consider the following:

• ഉപകരണം സജീവമാകുന്നില്ല:
  • Ensure the power supply to the switch is active.
  • Check the NPT tubing for blockages, kinks, or leaks.
  • Verify that sufficient pressure is being generated in the ductwork. The pressure sensing hole should ideally be located where pressure builds up, such as before an elbow or damper.
  • Inspect electrical connections for looseness or damage.
• Device Not Deactivating:
  • Ensure the pressure in the ductwork has returned to normal (i.e., the system it monitors is off).
  • Check the NPT tubing for any persistent blockages or foreign objects that might be maintaining pressure.
  • If the issue persists, the switch itself may be faulty and require replacement.
• ഇടയ്ക്കിടെയുള്ള പ്രവർത്തനം:
  • അയഞ്ഞ വൈദ്യുത കണക്ഷനുകൾ പരിശോധിക്കുക.
  • Ensure the pressure signal is consistent and not fluctuating rapidly.
