Fantech DB 10 Trykafbrydersæt Brugermanual

1. Introduktion

The Fantech DB 10 Pressure Switch Kit is a pressure-activated control device designed to automate the operation of various systems, such as dryer booster fans or ventilation systems. It features an integral delay function, ensuring stable and reliable performance by preventing rapid cycling. This manual provides essential information for the safe and effective installation, operation, and maintenance of your DB 10 Pressure Switch Kit.

2. Sikkerhedsoplysninger

ADVARSEL: Installation and servicing of this product should only be performed by qualified personnel. Disconnect power before installing or servicing the unit to prevent electric shock or equipment damage. All wiring must comply with local and national electrical codes.

• Brug altid passende personlige værnemidler (PPE) under installationen.
• Sørg for, at strømforsyningen matcher voltage requirements of the switch (115-120 Volts).
• Do not exceed the specified current rating of the switch.
• Keep all electrical connections dry and secure.

3. Hvad er der i æsken

The Fantech DB 10 Pressure Switch Kit includes the following components:

• 1 x DB 10 Pressure Switch with Integral Delay
• 1 x Section of NPT Tubing (approximately 3 feet)
• 1 x Grommet for Tubing
• 4 x Wire Nuts for Electrical Connection
• 1 x Packet with Switch Mounting Hardware (screws and wall anchors)

4. Installation

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

1. Vælg monteringssted: 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. Monter kontakten: 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. Tilslut rør: 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. Elektriske ledninger: 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. Bekræft forbindelser: Double-check all mechanical and electrical connections before restoring power.

5. Betjening

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. Vedligeholdelse

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

• Inspicer slange: 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.
• Tjek elektriske forbindelser: Ensure all wire nuts and electrical connections remain tight and free from corrosion.
• Rent ydre: Keep the exterior of the switch clean and free from dust or debris. Do not use harsh chemicals.
• Bekræft drift: Occasionally verify that the switch activates and deactivates as expected with the operation of the connected system.

7. Fejlfinding

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

• Device Not Activating:
  • 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 dampeh.
  • 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.
• Intermitterende drift:
  • Tjek for løse elektriske forbindelser.
  • Ensure the pressure signal is consistent and not fluctuating rapidly.
