Basic Usage Guide

1. Cut the coil legs to the ideal length using the included cutting tool.
2. Install your build in the postless deck (Single Coil with the reducer chamber or Dual Coil) and secure the screws.
3. Thread the cotton through the coils and seat the ends into the e-liquid retention channels without over-compact­ing.
4. Dampen the cotton with e-liquid, assemble the tank with the desired glass (3.5 ml or 4.5 ml) and fill from the top by turning the cap 1/4 turn.
5. Adjust the airflow ring to obtain the desired restriction (RDL to DL) and start vaping.

Maintenance and Care

• Avoid dry hits: happens when the cotton is dry, causing a burnt taste; keep liquid in the tank to prevent it.
• Clean the battery contacts, connections, and tank regularly to prevent dirt buildup and loss of flavor.
• Tune the airflow and power to avoid dry hits and extend the life of the coils.
• Avoid prolonged exposure to water, dust, or drops - although resistant, it still requires basic care.
• Store the device in a dry place away from extreme temperatures.
• Store liquids in a cool place and out of reach of children and animals. Use high-quality liquids from reliable brands to preserve flavor and avoid damage to the tank, try different Liquids or Concentrates to vary the flavor and avoid the "vaper's tongue," which occurs when the palate gets used to the same flavor. We recommend liquids 70% VG / 30% PG for coils below 0.6 ohm, and 50% VG / 50% PG for coils above 0.6 ohm.

Safety and Care

• Vaporization requires knowledge, care, and safety awareness. For a more comprehensive understanding of vaping and responsible use of our products to ensure a pleasant and safe experience, consult the FAQ (Frequently Asked Questions) from Contraste Vaping®.
• Clean the atomizer regularly to avoid residue buildup that could compromise performance and flavor. Disassemble and wash all removable parts periodically.
• Use only appropriate batteries, of high quality, preferably original and from reliable brands. Always recharge them with own chargers. Do not use damaged batteries or those with defective protectors.
• Keep connections clean and dry to avoid short circuits.
• Do not exceed the recommended resistance and power specifications of your Mod.
• Store the equipment and the batteries in a safe place, away from excessive heat and avoid prolonged exposure to water or moisture.
• If you notice swelling, battery overheating, strange taste, leaks or any other problem, stop use immediately and contact us.
