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.
