1.5 Health, safety and hygiene
Ensure that the following guidelines are observed:
• All work on the equipment must be carried out by trained personnel.
• The electrical supply is suitable for the equipment supplied.
• Refrigerant, temperature and pressure must agree with the data on the product label of the
relevant heat exchanger.
• As the heat exchanger is supplied indirectly, the producer is not acquainted with its actual
application.
• The heat exchanger should be installed in conformance with the recognized national standards
of electrical and refrigeration installation practice.
• The supplied heat exchanger is optimized for the refrigerants as stated in the data sheet or
order documents. The allowed maximum pressure is noted on the type plate. During production
the heat exchanger was subjected to a strength test exceeding the design pressure. However,
during normal use the design pressure may not be exceeded.
• Heat exchangers supplied by Alfa LU-VE are normally not equipped with a high-pressure cut
out. The installer is responsible for fitting a high-pressure cut out on the system in which the
heat exchanger is used.
• The heat exchanger shall not be blocked in. If the ambient temperature rises, the pressure could
rise and exceed the design pressure.
• It is not permitted to use the heat exchanger for any purpose other than the one it was designed
for by Alfa LU-VE.
• If the equipment is used in the food industry, responsibility with regard to hygienic conditions lies
with the end user.
1.6 Use of flammable gas
• The product must be stored and installed in rooms where the use of open flames or other
ignition sources is forbidden
• During transport, handling, installation, the product and, in particular, the pipes must be
protected to avoid physical damage which may cause it breakage.
• In the event of suspicious damages or doubts about the correct handling (eg. damaged
packaging) do not install the product before carrying out a thorough integrity check.
• Install the product only and exclusively in places that comply with the minimum size and/or air
exchange requirements established by the applicable standards, in relation to the total charge of
flammable fluid provided for in the installation in which it is incorporated.
• All ordinary and extraordinary maintenance operations must be performed only by qualified
personnel in the use of equipment with flammable fluid. special attention to operations that
require interventions on the pipes.
• The use of refrigerants different than those indicated in the data plate or in this manual is
forbidden.
In general, the use of refrigerants that are not included in the list of the IEC 60335-2-40 Annex b
standard is forbidden.
• Before performing any maintenance operation, exclusively by qualified staff, perform a check for
the absence of gas in the room and around the product through an appropriate detector.
• Before performing any operation for opening the pipes of the refrigerant circuit, by means of
mechanical operations or with open flames, make sure that the circuit does not have any
quantity, even minimal, of inflammable gas and that it has been washed internally with inert
gas (ex. nitrogen). all operations must be performed by personnel qualified in the use of
flammable gases.
• The product shall not be modified in any part of it, by removing or adding component.s
