Nauticam M14 Vacuum Valve II - Pushbutton Release

An exceptionally comprehensive vacuum system that allows the underwater photographer to confirm watertight integrity before entering the water. This system provides additional peace of mind with expensive camera equipment and should mean fewer lost dives due to minor equipment issues. The system is comprised of two parts, a one way vacuum valve and an electronic monitoring circuit.

Installing vacuum valve to housing

Press the red button to release pressure.   Remove the plug of the M14 accessory port from the housing. Remove the cap from the vacuum valve. Tighten the vacuum valve to the housing with the tool provided.

Building up vacuum

Remove the cap of the vacuum valve. Connect the hand pump to the valve and pump several times until it reaches the target vacuum level. The LED light will turn flashing yellow while vacuum is building up, then steady green when the target vacuum level is reached.

Attention: After the target vacuum is reached, i.e. steady green light, attach the cap back to the vacuum valve.

It is recommended to leave the housing for at least 20mins to ensure it is sealed. If the LED light changes from steady green light to rapidly flashing yellow light, that means there is a leakage and please check every O-ring and conduct the vacuum test again.

Please ensure that the cap is attached back to the vacuum valve before going underwater.

Vacuum can be released by pushing the red release button.

Attention: Please DO NOT attempt to go over the designated vacuum level, i.e. stop pumping when the LED turn green. Excessive vacuum level may lead to the malfunction of the camera and lens.

Note: Although the vacuum indicator is designated to compensate for a certain amount of temperature variation, it is recommended to conduct the vacuum test in an environment where the temperature is stable.

 After set up, the meaning of the LED indicator in the housing:


LED indicator Status
Flashing “Blue” light Standby mode. The moisture alarm is active, and the system is ready for vacuum indication whenever a vacuum is detected.
Flashing “Red” light with beeping sound Moisture is detected.
Flashing “Yellow” light Some vacuum is detected, target vacuum level is not reached.
Steady “Green” light Target vacuum level is reached.
Rapidly flashing “Yellow” light Vacuum is dropping. (Will occur only after target vacuum level is reached)
Rapidly flashing “Red” light Vacuum is totally lost. Circuit stalled until switched off. (Will occur only after target vacuum level is reached)

How long will it take for my order to arrive after I make payment?

That depends on where you live and whether we have an item in stock or not. While we do have many items in stock, we don't carry everything. If you need an item in a hurry, it's a good idea to contact us and find out if your item is in stock.

If it is, we can usually send it out as soon as we receive payment. If an item is not in stock, we'll need to order it from our suppliers, which means it can take 1-2 weeks to arrive at your door (usually closer to a week).

Sometimes delivery can take longer, if our manufacturers are out of stock, for example, but this is unusual - we let customers know as soon as possible if something like this happens.
