Instructions for a correct installation
Recommended distances
For the installation of more than one unit in the same cold or air-
conditioned room it is necessary to respect the dimensions indi-
cated in drawing.
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.
Important
1. Keep this manual for the lifespan of model.
2. Read technical manual carefully before installation and prior to
any intervention on model.
3. Use model exclusively for the purpose for which it has been
designed; misuse exempts manufacturer from any responsi-
bility.
Inspection - Transport
1. Upon delivery immediately examine condition of model; should
damages be detected promptly notify forwarder.
2. During transport of model it is necessary to avoid pressure on
packaging and it must be kept in upright position as indicated
on package.
3. 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.
4. In order to avoid injury from the model's sharp edges (e.g.
fins) during installation and positioning of model use of special
protective gloves is recommended.
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 negatively affect
the stated performance and may cause defects.
Standard models may not be suitable for blast freezer and
chill room application.
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 pressu-
res) are in accordance to those of project.
6. Care must be exercised during the connecting phase in order
to avoid possible distortion of the capillary tubes and shifting
of the distributor.
7. In the case of more than one model installed at close range it
is advisable to avoid alternate defrostings.
8. Fit the appropriate siphons on the condensate drain connec-
tions and assess their efficiency in all working temperatures.
9. Avoid installation of the units next to the cold-room doors.
10.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.
11.
Verify that the electrical feed network is in accordance to the
electrical features of model.
12.
Ensure that all the electric wiring is in compliance with the
standards in force.
13.
The protective film is to be removed from model upon comple-
tion of installation.
14.
Access to model, for any type of intervention, is reserved to
qualified personnel as per regulations in force.
General Maintenance
1. Periodically inspect fastenings, electrical connections and con-
nections 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 solvents, aggressive, abrasive or
ammonia-based agents.
3. When replacing electric heaters take particular care during
installation in order to avoid damage to the vulcanization; cor-
rectly reset wiring and existing fastening systems to avoid pos-
sible movement during operation.
The above-mentioned operations are to be carried out by
qualified personnel only.
