Important

1. Keep this manual for the lifespan of model.
2. Read technical manual carefully before installation and prior to any interven-
tion on model.
3. Use model exclusively for the purpose for which it has been designed; misuse
exempts manufacturer from any responsibility.
4. Any operation other than that indicated in this manual must be previously
agreed with the manufacturer. Non-compliance will void the warranty.
5. This manual reflects the state of the art at the time of marketing of the product
and therefore cannot be regarded as inappropriate in the case that evolution of
the design and construction methods require updating of the data expressed.
6. It is the responsibility of the installer/designer of the system to comply with the
current regulations and legislation and to assess its safety before putting it into
service.
7. All of the operations described in this manual must be performed by authorised
and qualified personnel, with the training and skills required by the EN 378
standard. No operation can be carried out by people under the influence of
drugs, alcohol or medicine that may affect the promptness of their reflexes.
Jobs are allowed only if an order has been given.
8. The design, construction and operation of the refrigeration system where the
unit will be installed must comply with the requirements and criteria indicated in
the EN 378 standard.
9. The safety requirements for the use of coolants belonging to groups A1 and
A2L must comply with the provisions of the EN 378 standard and of the safety
data sheets of each fluid used.
10. Prepare and plan measures in the event of an emergency on the system; for
example, install a fault warning system to prevent damage to people and pro-
perty.

Inspection - Transport

1. Upon delivery immediately examine condition of model; should damages be
detected promptly notify forwarder.
2. The exchangers are supplied with a pre-charge of dry air at 2 bar and have
load couplings of 1/4" SAE. Check for the presence of pressure. In the absen-
ce of pressure immediately contact the manufacturer and report the problem
on the transport document. Insufficient pressure indicates a loss due to
damage incurred during transportation.
3. During transport of model it is necessary to avoid pressure on packaging and
it must be kept in upright position as indicated on package.
4. Unpack model as close as possible to installation site. When packaging is
removed from model, care must be exercised in order to avoid damage to
parts.
5. In order to avoid injury from the model's sharp edges (e.g. fins) during instal-
lation and positioning of model use of special protective gloves is recommen-
ded.

For a proper installation

1. Verify structural bearing of ceiling in relation to the weight of the unit.
2. Verify that the unit is installed horizontally.
3. Ensure an adequate free space (approx. 30% of the inner room volume)
to allow a proper intake and exhaust air circulation.
Particular conditions of installation or operation such as low or beamed
rooms, overstorage, obstructed intake and exhaust air circulation and
improper ice build-up due to excessive entry of humidity in room may nega-
tively affect the stated performance and may cause defects.
Standard models may not be suitable for blast freezer and chill room appli-
cation.
4. The models are equipped with axial fan motors, therefore not suitable for duct
ventilation systems and cannot sustain extra static air pressure drops.
5. Verify that the operating conditions (temperatures and pressures) are in
accordance to those of project.
6. Before cutting of the input and/or output pipes discharge the pre-load pressu-
re (2 bar approximately) from the exchanger
7. Care must be exercised during the connecting phase in order to avoid possi-
ble distortion of the capillary tubes and shifting of the distributor.
Caution
Before carrying out maintenance on unit, make sure that the electric feed is
disconnected from main power source: the electric parts may be connected to
an automatic control system.

8. In the case of more than one model installed at close range it is advisable to
avoid alternate defrostings.
9. Fit the appropriate siphons on the condensate drain connections and assess
their efficiency in all working temperatures.
10. Avoid installation of the units next to the cold-room doors.
11. Place the end of defrost temperature feeler in the coldest areas of the coil,
i.e. the areas that tend to freeze more (at the end of the cycle the unit should
be completely ice-free).
The position of this device cannot be defined in advance, because it varies in
accordance to the type cold room and type of installation.
12. Verify that the electrical feed network is in accordance to the electrical featu-
res of model.
13. Ensure that all the electric wiring is in compliance with the standards in force.
14. The units are predisposed for ground wiring connection.
The unit installer and/or plant operator must ensure the presence of an effi-
cient earthing connection to protect against indirect electric contacts.
The electric heating elements eventually used for defrosting are housed in
junction boxes made of thermoplastic material, with protection rating IP 54.
Upon request, models can be supplied with coils, defrosting units and fan
motors different from the standard ones.
15. The protective film is to be removed from model upon completion of installa-
tion.
16. Access to model, for any type of intervention, is reserved to qualified person-
nel as per regulations in force.

General Maintenance

1. Periodically inspect fastenings, electrical connections and connections to
cooling installation.
2. It is necessary to arrange periodical cleaning of unit in order to avoid deposits
of toxic substances. Use of mild detergent is recommended; avoid use of sol-
vents, aggressive, abrasive or ammonia-based agents.
3. When replacing electric heaters take particular care during installation in
order to avoid damage to the vulcanization; correctly reset wiring and existing
fastening systems to avoid possible movement during operation.
The above-mentioned operations are to be carried out by qualified person-
nel only.

Hazards / Risks

1. Electric shock. The model is equipped with fan motors and
electric defrost heaters. The supply voltage is 400 V AC. It is
important to use electrical safety systems that are in
compliance to the regulations in force.
2. Burns. The surface of the electric defrost heaters can reach the
temperature of 350 ° C.
3. Cuts. The heat exchanger is made with fins with sharp edges
and the casing is made of sheet metal parts.
4. Parts in motion. The model is equipped with fan motors fitted
with external protection.
5. Crushing. The weight of unit may exceed 70 kg.
