G Pen Hyer Cleaning Guide

To maintain the optimal performance of your G Pen Hyer, regular cleaning is recommended. Follow these steps to ensure a clean and enjoyable experience with your device. Please note that the following cleaning directions apply to both the quartz chamber and the optional dry herb tank.

Note: For the best experience, it is recommended to swab the quartz chamber or dry herb tank between each use, once they have cooled down. This will help maintain cleanliness and reduce the need for deeper cleaning.

  1. Wait for Cooling: Ensure that the unit has completely cooled down after the last use. Remove the cap and unscrew the tank to begin separating the device.

  2. Detach the Water Piece Adapter: Gently pull the water piece adapter to detach it from the device. Remove the o-rings from the adapter as well.

  3. Clean with Isopropyl Alcohol: Thoroughly swab or wipe down the tank, water piece adapter, o-rings, top cap, and any other areas where residue may have accumulated, using isopropyl alcohol. This will help remove any buildup and ensure a clean surface.

  4. Allow for Drying: Once you have cleaned all the components, allow them to dry completely before proceeding to the next step. Ensure that all surfaces are free from moisture.

  5. Reassemble the Device: Screw the tank back into the unit. Replace the o-rings on the water piece adapter. Carefully put the unit back together, ensuring all parts are securely attached.

  6. Evaporate Residual Alcohol: Set the G Pen Hyer to the highest heat setting and run it empty for a few minutes. This will help evaporate any residual alcohol and ensure that the device is ready for regular use.

Following these cleaning steps will help maintain the cleanliness and performance of your G Pen Hyer, providing you with consistent and enjoyable sessions.
