Carry out water analysis at the necessary time intervals (refer to user's manual).
–
Perform water treatments in order to bring the characteristic values back within the limits specified in the use and
maintenance manual. (ref. EN12953-10)
–
Keep water at a temperature above 60°C to facilitate deoxygenation
PRESENCE OF SLUDGE
–
Carry out water analysis at the necessary time intervals (refer to user's manual).
–
Perform water treatments in order to bring the characteristic values back within the limits specified in the use and
maintenance manual. (ref. EN12953-10)
–
Blowdown by working on the drain valves present on boiler bottom.

–
Before opening the hatch, it is necessary to check that the pressure in the boiler body is equal to the atmospheric one (0
relative bar)
ACCIDENTAL OPENING OF HATCH, HANDHOLE OR HEADHOLE, IF ANY
–
Before opening the hatch, it is necessary to check that the pressure in the boiler body is equal to the atmospheric one (0
relative bar)
DOOR ACCIDENTAL OPENING
–
Before opening the door, check that the burner is off and disconnected.
–
The wall temperature must be such not to injure the operator
HOT SURFACES
–
Insulation with glass wool or refractory materials in general of the parts that can come into contact with hot surfaces during
standard use and maintenance conditions
–
Avoid contact with generator uninsulated parts during operation. Should adjustment or check activities be carried out during
operation, the operators must wear suitable protective equipment (gloves, shoes and thermal coverall)
–
The boiler should feature plates warning on the presence of hot parts.
SHOCKS AND ACCIDENTAL FALLS
–
Anti-slip embossed upper walk-on platform.
–
Climb on or off the roof to carry out ordinary and extraordinary maintenance operations using a suitable ladder and anti-slip
