4. Sikkerhedsoplysninger
Read and understand all safety warnings and instructions before installing or operating this product. Failure to follow these instructions may result in electric shock, fire, serious injury, or property damage.
- Elektrisk sikkerhed: Sørg for, at strømforsyningen matcher den nominelle voltage (220V) and current (10A) of the pressure switch. Disconnect power before making any electrical connections or performing maintenance. All electrical wiring should be performed by a qualified electrician and comply with local electrical codes.
- Tryksikkerhed: This device operates under high pressure. Always depressurize the air system before installing, removing, or servicing the pressure switch. Use appropriate personal protective equipment (PPE) such as safety glasses.
- Installation: Do not modify the pressure switch. Use only original or approved replacement parts. Ensure all connections are secure and leak-free.
- Miljø: Do not expose the pressure switch to excessive moisture, dust, or corrosive environments. Operate within specified temperature ranges.
5. Opsætning og installation
The Zunate FBANG-four holes pressure switch is designed for easy integration into air compressor systems. Follow these steps for proper installation:
- Strømafbrydelse: Ensure the air compressor is completely disconnected from its power source to prevent accidental startup.
- Trykaflast systemet: Fully drain the air tank and ensure there is no residual pressure in the system.
- Montering: Securely mount the pressure switch to a stable surface or directly onto the air compressor manifold. The four-port design allows for flexible orientation.
- Luftforbindelser: Connect the main air line from the compressor tank to one of the G1/4 ports on the pressure switch. Use appropriate thread sealant (e.g., PTFE tape) on all threaded connections to ensure an airtight seal.
- Accessory Connections (Optional): Utilize the remaining G1/4 ports for additional components such as a pressure gauge, safety relief valve, or auxiliary air outlets as needed.
- Elektriske ledninger: Connect the electrical wiring from the compressor motor to the appropriate terminals on the pressure switch. Refer to the wiring diagram provided with your air compressor or consult a qualified electrician. Ensure correct polarity and secure all connections.
- Lækagetjek: Once all connections are made, slowly re-pressurize the system and check for any air leaks using soapy water. Tighten connections as necessary.

6. Betjeningsvejledning
The Zunate FBANG-four holes pressure switch operates automatically once properly installed and powered. It is pre-set to maintain pressure within a specific range.
- Indledende opstart: After installation and safety checks, connect the air compressor to its power source.
- Tilkoble kontakt: Move the manual ON/OFF lever to the 'ON' position. The compressor should start running if the tank pressure is below the cut-in pressure (75 psi).
- Automatisk drift: The compressor will run until the tank pressure reaches the cut-off pressure (120 psi), at which point the pressure switch will automatically turn off the compressor motor.
- Trykfald: As air is used and the tank pressure drops to the cut-in pressure (75 psi), the pressure switch will automatically restart the compressor to replenish the air supply.
- Manuel slukning: To manually turn off the compressor, move the ON/OFF lever to the 'OFF' position. This will stop the compressor regardless of the tank pressure.

7. Vedligeholdelse
Regular maintenance ensures the longevity and reliable operation of your pressure switch. Always disconnect power and depressurize the system before performing any maintenance.
- Inspektion: Periodically inspect the pressure switch for any signs of wear, damage, or corrosion. Check for loose electrical connections or air leaks.
- Rensning: Keep the exterior of the pressure switch clean and free from dust, dirt, and debris. Do not use harsh chemicals or solvents.
- Funktionstjek: Regularly verify that the pressure switch is cycling the compressor correctly within its specified pressure range (75-120 psi).
- Udskiftning: If the pressure switch shows signs of malfunction, inconsistent operation, or significant wear, replace it with an original Zunate FBANG-four holes G1/4 Automatic Pressure Switch or an equivalent approved part.
