Cressi sub accepts no responsibility for actions on the dispensers carried out by an authorized and specifically trained by the same Cressi sub.

• Cressi-Sub recommends complete regulator maintenance at least once a year, or more frequently in the case of particularly intense use.

• Maintenance must include replacement of all components provided in the annual equipment maintenance kit.• The special tools for maintenance of this device are illustrated on one of next pages.• Metal parts must be washed with hot water and neutral detergent and rinsed in fresh water. Any concretions

must be removed using ultrasound cleaning or with diluted acid solutions, always followed by long and thorough rinsing under running water. For more information, please refer to the general procedure.

• Do not use acids or solvents on rubber components.• The new ORs must be greased with a thin layer of lubricant: this procedure reduces to a minimum the risk of

damage during assembly.• The metal threading can be lubricated with grease on the first two rings of threading.

Assembling procedures

After replacing the bracket nut O-Ring,

place the INT bracket between

the nut and the first stage body. Press

the nut onto the filter and overcome the spring resistance

down to the thread inside the first stage body. Screw the nut completely, keeping the first stage firmly on the work top, so that the O-ring will be placed correctly

into its seat.

• MC9 1st stage setting procedures, referring to the picture on page 193:• Connect the setting pressure gauge with one of the first stage LP ports• Connect the whole regulator (including both 1st and 2nd stages) with a 200 bars (2900 psi) pressurized tank,

or with an equally pressurized workbench.• Note: even though the regulator is overbalanced (that is, the intermediate pressure increases as tank pressure

decreases), it’s a good idea to calibrate the first stage to 200 bar / 2900 psi to properly control how the regulator functions. Intermediate pressure will rise slightly as pressure in the tank drops (circa + 0.6 bar / + 9 psi at tank 50 bar / 725 psi).

• Turn slowly the air valve on, while pressing the second stage air outlet button.• Do that some times more.

• Check the pressure on the gauge. MC9 first stage is correctly set at an intermediate pressure of 10 bars (146 psi). If it is different, close the air valve and discharge the regulator. Use a 6 mm. Allen wrench to turn clockwise (+) the setting screw, in order to increase the first stage intermediate pressure. Turning it anticlockwise (-), the pressure will on the contrary decrease.

• Note: make sure to discharge the regulator before setting the intermediate pressure, in order to avoid incorrect reading on the gauge.

• Make sure the intermediate pressure is reached swiftly and stays so, and does not increase after pressing the second stage discharge button for more times.

• After the setting, when pressing the second stage discharge button, the first stage pressure must decrease less than 1 bar (14,6 psi).
