5. General Usage Guidelines:

  • Always use the SMACO with care.
  • When not in use, purge air from head regulator.
  • Excessive stress on the membrane can cause excessive air expulsion, block the mouthpiece to stop this.
  • Keep sand and other debris away from the Smaco tank, hand pump, and 12 V compressor.
  • Avoid prolonged exposure to sunlight.
  • Test the tank thoroughly before first use to get a feel for it.
  • In case of leaks or suspected malfunction, stay clear of the equipment, close the valve, refer to these instructions and contact your dealer if necessary.

5.1. Pre use precautions:

  • To ensure safe use of the equipment, it is important for the user to be in good health and consult a health specialist if necessary.
  • Before diving or filling the equipment, visually inspect it to ensure that the head regulator is properly secured.
  • Perform 2-3 inhale/exhale cycles as a test before entering the water to verify proper function.
  • Do not rotate any elements after pressurizing, except as directed by the
  • Always monitor pressure gauge.

5.2. During use precautions:

  • To ensure safe use of the equipment, always maintain a continuous breathing pattern.
  • Use the SMACO mini scuba tank in water above 50°F (10°C). The equipment should only be used by one person at a time, and the maximum depth is 10m (32ft).
  • Regularly check the remaining pressure in the tank using the pressure gauge. If the remaining pressure is equal to or less than 50 bar (725 PSI) (red zone on the pressure gauge), the user MUST return and stay at the surface.
  • If there is a leak from the Tank, slowly return to the surface and stop using the equipment.
  • WARNING: Never ascend faster than the air bubbles, stop the dive if you experience discomfort in your ears or sinuses, do not dive if you have a cold.
  • Never hold your breath during descent or ascent.
  • Do not submerge the SMACO when it is not pressurized.

5.3. Post use precautions:

  • Release the pressure from the head regulator by pressing the membrane.
  • Rinse the equipment with clean water.
  • Allow the equipment to dry completely.
  • WARNING: Do not clean the equipment using aerosols or solvents. When cleaning the head regulator, be gentle as a strong jet of water through the mouthpiece can damage the internal membrane.

6. Refilling compressed air:

  • The individual responsible for refilling the tank is accountable for the quality of the compressed air.
  • When refilling the tank, if there is a discrepancy between the pressure in the refilling tank and the pressure gauge of the tank being refilled, use the higher value.
  • WARNING: The Tank should not be refilled with a pressure exceeding 200 bar (3000 psi). It is the responsibility of the person refilling the tank to ensure that this limit is not exceeded.

6.1 High pressure pump:

To refill the Tank with the Hand pump, please follow these instructions:

  1. Connect the pump's female clip to the male clip of the head regulator by ensuring a secure "click" connection.
  2. Pump until reaching the desired pressure.
  3. Open the pump valve to release the pressure, enabling you to remove the clip from the Tank.


  • It is advised not to use the pump for more than 5 minutes continuously, as a cooling period is necessary.Between each pumping cycle, you can release pressure from the pump to allow it to cool (keep the tank connected).
  • The optimum pumping cycle is 2 minutes 30 seconds of pumping, followed by a short pause, then pumping again.
  • Only use high pressure manual pumps sold by SMACO that are compatible with SMACO.
  • Do not leave the pump connected under pressure when not in use.
  • Always ensure the pressure gauge of the hand pump matches that of the SMACO cylinder pressure gauge.
  • Make sure that no dust, water traces or other foreign elements are present in the clips when the protections are removed.
  • Incorrect orientation of the male clip in the female clip can cause a micro-leak. In this case, reposition the clip so that the weight of the tank does not put stress on the clip.
  • Change the filters inside the cartridge after 5 full fillings of the tank - foam filters and carbon balls are already supplied with the pump.

6.2 Air compressor:

To connect the 12 V compressor to the Tank:

  • Connect the wires from the battery or inverter to the compressor.
  • Connect the high-pressure hose to the compressor by attaching the female clip of the hose to the male clip of the compressor, ensuring a secure "click" connection.
  • Attach the female clip of the cartridge to the male clip of the head regulator, ensuring a secure "click" connection.
  • Fully screw in the brass decompression valve.
  • Turn on the fans by pressing the fan switch (verify that the fans are working).
  • Turn on the compressor by pressing the power switch.
  • Compare the pressure of the compressor with the one of the tank regularly.
  • Monitor the temperature display, the temperature should not exceed 85°C (185°F).
  • Allow the compressor to run until the desired pressure is reached (maximum 200 bar/3000 psi).
  • Unscrew the brass decompression valve to release the pressure from the hose.
  • Disconnect the tank from the cartridge by releasing the female clip.
  • Replace the filters inside the cartridge with a new mix of molecular sieve and active coal.
  • WARNING: Take a break during filling if the temperature becomes too high.

7. Potential Hazards:

  • Failing to adhere to basic scuba diving guidelines can result in the risk of drowning or physical harm that may lead to death.

Failing to follow these instructions can expose you to dangers that can have serious consequences for your health.


  • Scuba diving is a risky activity if done without knowledge of safety rules. This document provides the main tips to follow and avoid making your dives an enjoyablevleisure time. Other tips may be provided by qualified diving instructors.

Safety Rules & Basic Advice

  • Prior to diving, it is highly advisable to consult with a doctor to assess your fitness to dive. If you have a history of cardiovascular disease, asthma, diabetes, heart disease, or vascular issues, ENT diseases, epilepsy, or other neurological disorders, scuba diving is strongly discouraged. The same applies to temporary conditions such as colds, sinusitis, bronchitis, infections in the nose, throat, ears (otitis), or teeth (caries). Other factors that should cause you to avoid scuba diving include peptic ulcer disease, retinal detachment, glaucoma, enlarged spleen (splenomegaly), or pregnancy.
  • Do not fly or travel to high altitudes on the same day as diving.
  • Throughout the dive, adopt a continuous breathing pattern and regularly check your pressure gauge.
  • Do not use earplugs as they prevent pressure equalization. Dive only if you feel good and hydrate yourself before and after the dive to avoid drying out the mucous membranes due to cool and dry air.

The Descent

  • The descent (even shallow) leads to an increase in ambient pressure. To maintain equal pressure between you and the environment, you must perform the Valsalva maneuver. This involves blowing (slowly) while pinching your nose and keeping your mouth closed. By performing this operation, you avoid the main risk during the descent: barotrauma, which mainly affects the eardrums and sinuses. If you are unable to perform this procedure correctly, do not go deeper and ascend slowly to the surface.

The Ascent

  • During the ascent, it's important to perform the Toynbee maneuver by pinching your nose and swallowing (swallowing saliva).
  • Pulmonary overpressure accidents are one of the most serious dive accidents, and occur when a diver stops breathing during an ascent. To avoid this, it's crucial to maintain a flexible and continuous breathing pattern. The diver's ascent speed should not be faster than the small air bubbles.
  • For experienced users and graduates of an accredited center, the ascent from a significant depth may require decompression, depending on the dive time and depth reached. The goal is to remove the nitrogen accumulated in the body. If you ascend too quickly, the nitrogen will not be eliminated and gas bubbles can cause risks such as paralysis or thrombosis.
  • If you experience pain or discomfort during the ascent or descent, stop your progress and ascend slowly and gradually while controlling the pressure of your tank and breathing.

Physical Effort

  • Avoid making unnecessary efforts before, during, and after the dive and avoid apnea before and after the dive.
  • Do not attempt to exceed your limits, as the Smaco equipment is not designed for performance.
  • Manage your breathing and if you experience shortness of breath, ascend slowly and gradually.

Adapting to the Dive Environment

  • When underwater, it is important to only touch elements that you are familiar with and that are safe to touch.
  • Adapt your dive to the environment and be aware that poor visibility can be a stressful factor.
  • Stress can often lead to accidents, so it's important to manage stress to ensure a safe dive.
  • Properly equip yourself for the dive environment by choosing a suitable mask, flippers and consider carrying an emergency buoy.
  • Cold water can also be a stress factor, so it's important to wear suitable wetsuits or dry suits to reduce potential problems such as breathlessness.
  • Avoid diving in rough or choppy waters and make sure to check the current and weather forecast before diving.
