Maintenance Tips
- Rinse thoroughly with fresh water after every dive, including flushing the second stage inlet and exhaust ports while pressing the purge lightly to remove salt and sand buildup.
- Do not submerge or soak for long periods with the hose disconnected; always keep the inlet protected with a proper dust cap during rinsing.
- Operate purge button and (if fitted) Venturi lever while rinsing to keep internal mechanisms free of salt deposits and sticking.
- Allow to air dry completely in a shaded, ventilated area before storage to prevent moisture damage and corrosion.
- Store loosely coiled in a cool, dry place away from heat, UV exposure, and ozone sources (like motors or batteries).
- Inspect mouthpiece, exhaust tee, diaphragm cover, and hose connection regularly for cracks, looseness, or salt buildup.
- Avoid sand, oils, solvents, and chemical exposure that can degrade seals and internal valve performance.
- Have the S600 professionally serviced at least annually or per manufacturer schedule to maintain safe breathing performance.
