• Rinse thoroughly with fresh water after every dive, keeping the yoke dust cap securely fitted to prevent water entering the MK11 EVO first stage.
• Lightly operate the purge button and (if fitted) Venturi/pre-dive switch on the R105 while rinsing to clear salt and sand from moving parts.
• Never pressurize the system during soaking unless properly connected; ensure the inlet is protected to avoid contamination of the first stage.
• Allow to air dry completely in a shaded, ventilated area away from direct sunlight and heat to protect seals and internal lubrication.
• Store hoses loosely coiled to avoid kinks and stress on fittings or hose connections.
• Inspect hoses, mouthpiece, yoke O-ring, exhaust tee, and second stage cover regularly for cracks, wear, or salt buildup before every dive.
• Avoid exposure to sand, oils, solvents, chlorine, and harsh chemicals that can degrade rubber seals and valve performance.
• Have the MK11 EVO and R105 professionally serviced at least annually or according to manufacturer schedule (or ~100 dives in heavy use).
