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. Please contact Alfa LU-VE before using any other refrigerants. 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 Checks at delivery
At the moment of delivery, carefully check the units.
All finned coils are pressure tested with dry air, sealed and supplied with a slight overpressure. Prior
to installation, the leak resistance must be checked with the schrader valve.
Any present damage must be reported on the delivery note with a description of the damage.
Damaged heat exchangers, including when the damage is not externally visible, are to be reported
to the shipping agent and Alfa LU-VE within 24 hours.
1.7 Return of unused heat exchangers
Air heat exchangers that have been delivered in accordance with orders are in principle not
returnable. Heat exchangers can only be returned under certain conditions and following
consultation with Alfa LU-VE. This applies exclusively to unused units. The heat exchangers that
are to be returned should be delivered carriage paid to Alfa LU-VE in the original, undamaged and
unwritten factory packaging. Not returnable are:
• Heat exchangers older than three months from the invoice date.
• Heat exchangers that have already been built in and/or are damaged.
1.8 Guarantee
For our guarantee conditions, we refer to the Terms of Delivery. In general, the warranty period
between Alfa LU-VE and the customer is 24 months from factory invoice date or 12 months of
operation, which ever comes first. Heat exchangers must not be returned or disposed of, other
than in accordance with instructions from Alfa LU-VE. Contact your local Alfa LU-VE representative
before any remedial action is taken on the units, otherwise warranty may be void.
1.9 Disposal
After decommissioning the heat exchanger coil should be emptied from refrigerant fluids. Avoid
any emissions in the environment. Any refrigerants and oil residuals must be properly disposed of
according to applicable environmental regulations. The fully emptied heat exchanger unit, including
all electrical components, should be handed in to the proper authorized companies for recycling.

4 Transport and storage
During transportation the heat exchanger must be handled with all required care. Any instruction or
warning signs attached to the heat exchanger or the packaging must be followed. Avoid shocks or
continuous vibrations during transport. These may cause damage to the product. If required, consult
Alfa LU-VE and disassemble during transport any parts that are likely to be set into vibration. Air
heat exchangers must be adequately fixed on the transport vehicle. If temporary storage of the heat
exchanger is required, the following points should be observed:
• Store the heat exchanger in its packing, in a dry place with sufficient protection against sun and
other environmental influences.
• Always place air heat exchangers on an even surface.
• Do not stack air heat exchangers unless explicitly indicated this is allowed.
• Storage temperature between -40 °C and +50 °C.
• Never open or remove the schrader valves. Overpressure in the coil must be maintained.
Shelf life of air coolers is one year. If longer storage periods occur, check:
• Proper functioning of the fan motor.
• Mounting brackets, lifting lugs and fan fixings for corrosion.
Optigo FMS air coolers are delivered in a reinforced cardboard box. Handling and positioning can
take place manually. When more units are delivered in a single shipment, packed air coolers may
be stacked during transportation.
5 Unpacking and lifting
Remove the packing and take out cooler unit. Remove the transparent protection film from metallic
parts, if present.

Ensure that the cooler is not lifted directly onto
the driptray or the finned coil. Utilizing the proper
wooden transport beams and/or pallets prevents
the cooler bending at the extremes such that
the cooling circuit or other components are
damaged.
Lift the unit to mounting position and secure
following instructions given in chapter "6
Installation". After having secured the cooler,
the forks may be lowered and the remaining
packaging materials can be removed.

6 Installation
6.1 Mounting dimensions
Coolers must be hung such that the coolers can contract and expand somewhat. Cooler contraction
occurs during refrigeration operation, and cooler expansion occurs during defrost. For air coolers
with copper tubing this figure runs up to 1.65 mm per meter cooler length. All heat exchangers must
be set up level. Weight information are listed on the product label and/or in the relevant product
documentation.
