How to Install the Compressor for your K&A

This guide outlines how to install and connect the compressor, including oil filling, tubing connections, regulator installation, and pressure adjustment components.

Step 1: Add Compressor Oil

  1. Locate the oil fill side of the compressor:

    • European units: Typically use the left side.

    • North American units: Typically use the right side.

  2. Use the included oil bottle:

    • Pour oil slowly into the designated oil container.

    • Watch the bubble level on the side of the compressor.

    • Stop when the bubble is halfway full. This usually takes about 70–80% of the bottle.

⚠️ Do not overfill. Overfilling can damage the compressor.


Step 2: Connect the Tubing

Follow the layout in the compressor schematic:

  • Attach the silicone water removal tube to the designated port.

  • Close the Vent output securely.

  • Install the muffler for noise reduction.


Step 3: Install the Regulator & Filter Assembly

  1. Apply Teflon tape to the ¼” NPT-to-6mm fitting (included in your parts bin).

  2. Thread the fitting into the regulator/filter:

    • Use an Allen wrench in the fitting body for better control.

  3. Attach the regulator/filter assembly to the compressor using a crescent wrench.

    • Ensure a snug and airtight fit.


Step 4: Final Connections & Components

Refer to the front panel and component layout:

  • Power Switch: Turns compressor on/off

  • Manual Pressure Switch: Use to activate/deactivate compressor manually

  • Pressure Adjustment Dial: Fine-tune output pressure

  • Water Removal Switch: Releases built-up moisture from trap

  • Display Gauge: Shows active pressure

  • Water Trap & Pressure Adjustment Unit: Ensures stable output to instrument

  • Connect the 6mm output tube from the regulator to your instrument’s gas inlet


🔧 Maintenance Tip:

Drain the water trap regularly using the manual water removal switch to prevent moisture buildup and damage.
