The regulator and the diving vest are frequently thought of as being indestructible and of unlimited performance. At the same time, it is assumed that it doesn’t matter if a gear is rented, lent by a diving school or is one’s own gear. When it comes to the regulator, on which the diver’s life depends, it is important to follow the manufacturer’s instructions to ensure the optimum condition of the gear.
Regulators must comply with regular maintenance to function perfectly during their service life. An active diver’s regulator (15 to 20 dives per year) only needs annual servicing, but in case of rented gears, the servicing has to be carried out more frequently (every 3-6 months).
A regulator also requires technical review when whistles and noises are heard at the moment of inhaling. A review is becoming necessary as well when the conical filter at the inlet of the first stage is oxidized, presents residues or is clogged.
It is advisable to have the regulator serviced by a specialized centre where tools and appropriate products are available.
Maintenance consists in:
Check for leaks by pressurizing the regulator and submerging it in the water. Any air loss can easily be seen.
Disassemble and inspect the elements: follow the manufacturer’s instruction.
Cleaning: It is best to clean the parts with specific products such as Careli REGULATOR CLEANER. This product allows degreasing and cleaning the parts by any method, immersion, by hand or by ultrasound.
If the cleaning is done by immersion or by hand, we recommend working at a dose of about 25%, at room temperature and allowing the product to act for half an hour; yet the product can be left on to act for hours as it is gentle on most of the materials.
If the cleaning is done by ultrasound, we recommend working at a dose ranging from 3% to 5%, at a temperature of 50ºC and 60ºC, allowing the product to act from two to six minutes, according to the degree of dirt of the parts.
Replacement of the elements: Replace those parts specified by the manufacturer or those which are defective or worn. Perform a lubrication of the parts.
Assembly: Carry out as indicated by the manufacturer.
Calibration and testing: In the first stage the intermediate pressure is checked and the value, specified by the manufacturer, is adjusted. In a second phase adjust the valve lever position.
In addition to the regular maintenance, it is important to follow the steps below after every dive:
- Purge regulator several times while connected to the air tank to remove any traces of water and prevent moisture.
- Remove the dust cap with the air from the bottle and place it on the air inlet of the first stage and adjust.
- If the second stage has an adjustable breathing effort device, then close slightly the adjustment to prevent water from getting into the hose.
- Place the regulator in a freshwater bath for 30 minutes to remove waste and excess salt.
- Rinse with water
- Keep regulator dry and the second stage upwards to drain water that may remain in the hoses.
ENJOY YOUR DIVING!
