Warranty; Residual Risks - Riello SP20-DN32 Manuel D'utilisation Et D'entretien

1.3 - Warranty

• The warranty is valid only if the heat exchangers operate
under the conditions for which they were initially designed.
• The warranty can be applied only if pressures and tem-
peratures of the fluids can be measured on the heat ex-
changer's inlets and outlets.
• Spare parts are warranted only if the storage instructions
have been followed (see the section STORAGE).
The plate pack is surrounded by a strap (the so called war-
ranty seal) that, if left unbroken, is proof that the exchan-
ger has never been disassembled.
Removing this strap, without written authorization of the
manufacturer, will always void the warranty.
For more details about warranty terms check the
certificate provided during initialization of the system.

1.4 - Residual risks:

damage > cause (prevention)
POSSIBLE BODILY INJURY
• Unit tipover > Failure to follow the handling or anchoring
instructions (the unit has a very high centre of gravity; follow
the rigging instructions; anchor the unit to the floor).
• Burns > Direct contact with the unit while in operation or
with scalding or corrosive fluids following a leak (cut off the
supply to the unit; set up barriers around it; wear PPE =
Personal Protective Equipment).
• Cuts > Handling the plates without protective glove
(wear PPE).
• Injury > Caused by pressure, affecting in particular the eyes
or bare skin (wear PPE and prohibit access by unauthorised
personnel).
• Poisoning > Skin contact with, or inhalation of, a dangerous
fluid (wear PPE and use safety equipment).
• Poisoning > Combustion of the gaskets (never dispose of the
gaskets by burning them).
• Poisoning > Accidental mixing of circulating fluids resulting
in the release of hazardous fumes (make sure that resulting
mixture is not dangerous).
COMMON TYPES OF EQUIPMENT DAMAGE
• Gasket destruction > One fluid circulated at a high temperature
(always circulate the cold fluid FIRST and the hot fluid LAST).
• Gasket destruction > Sudden changes in pressure or tem-
perature (monitor the control).
