Maintenance
Make sure you put the dust cap on properly.
Soak the regulator in a tray of fresh water.
DANGER: If you use a hosepipe, do not use a pressure jet to clean the 2nd stage. The pressure of the jet could damage the membrane and/or the internal valve.
Wipe the regulator dry.
Do not expose your regulator to full sunlight for a lengthy period.
Storage
Store your regulator in a clean environment away from light and at a moderate temperature.
Do not store it near a source of heat or in a room that may contain chemical vapours like chlorine, ozone, etc. (e.g. a swimming pool machine room).
Never store the regulator on top of a cylinder/tank
DANGER: Never use solvents or hydrocarbon-based products to clean or lubricate your regulator. Never use spray cans.
Servicing and inspections
Aqualung advises you to service your regulator every two years and to make a visual inspection at least once a year.
These two inspections should be carried out by a Aqualung approved workshop
Your regulator should be serviced more frequently depending on the number of dives and conditions of use.
