4.1. CLEANING AND DISINFECTION
Dirty parts must be cleaned after each use. Clean with warm and soapy water. Rinse with running water. Remove dust
build-ups with a damp cloth or anti-static product.
Please note: Follow the concentration instructions when using chemical products to disinfect the device. Avoid using
organic solvents that can damage the rubber and plastic parts.
4.2. CYLINDERS
Follow the existing laws and regulations of the countries where the types of cylinders are used to fill and retest them.
When filling the cylinder, you can exceed the maximum operating pressure by about 10% since, at room temperature,
the pressure will drop back to the nominal value.
When filling, make sure:
• the air complies with the EN 12021 standard.
• the cylinder was checked within the time limits established; this can be done by checking the date of the last retesting
on the label.
The valve of the cylinder must be kept closed during transport to prevent humidity from penetrating and condensing.
During transport and storage, the cylinders must be protected from shock.
Do not grasp the valve to transport the cylinders.
4.3. SCHEDULED MAINTENANCE
The following table reports the scheduled maintenance operations:

1: Before allowing the use - 2: Before use - 3: After use - 4: Every six months - 5: Yearly - 6: Every three years - 7: Every six years
a) After use in corrosive environments or under extreme environmental conditions
b) According to the national laws
c) ATTENTION: Every time you disassemble the valve of the cylinder, you must replace it with a new one. Refer to the instructions
manual of the cylinder and valve for the proper torque values. After replacing any part, you must carry out all the operating and
pneumatic tightness checks.
4.4. CHECKS
Warning: the following checks must absolutely be carried out after cleaning or replacing the components.
The membrane of the demand valve, like all rubber parts, must be replaced if they show signs of alterations or
deterioration such as cracks, sticky parts, deformations, etc. All the connections must slide well without being hindered
and they must not show any signs of damage.
Some of the following tests can be carried out by means of special tools SPASCIANI can provide upon request.
4.4.1. Demand valve tightness at +7 mbar pressure
Connect the cylinder to the reducer; the cylinder must be left closed
•
Connect the demand valve to the medium pressure hose
•
Unlock the lock button by pressing on the button in the middle of the cover (pos. 1 in Fig.3)
•
Connect the demand valve to the testing equipment
•
Create a pressure of about 7 mbar in the demand valve.
•
The pressure drop should not exceed 1 mbar per minute.
