MT TC A DF EN 04 2017MT TC A DF EN 04 2017

TC 6.7

In environments with multiple units no alternating defrosting cycles should be carried out, in order to avoid the

abnormal formation of frost on the heat exchangers.

TC 6.8

Check that the power line is compliant with the requirements of the unit shown on the technical data label.

TC 6.9

Before connecting the unit, verify the presence of disconnecting and breaking devices on the power supply line,

protection against electric shock, protection of equipment and any other device required by law. Standard models

are supplied with junction boxes for the supply of fanmotors and with junction boxes for the supply of the heating

elements in models with electric defrosting.

TC 6.10

If speed controls are used for the fanmotors, check their compatibility. Non-compliant devices may generate noise and

damage the fanmotors. The manufacturer does not guarantee the indicated performance of units equipped with speed

controllers.

TC 6.11

Verify that the line of the refrigerant is adequate for the performance of the unit. When connecting the cooling circuit,

do not deform the capillaries and do not change the position of the distributor or the manifolds in general.

TC 6.12

Verify that the operating condition limits (humidity, temperature and pressure) meet the specific requirements of the

product selection.

TC 6.13

For units with electrical defrosting and, depending on the type of cold room, correctly dene the time and the number of

defrosting cycles. e defrosting cycle must be controlled with a chrono-thermostat and the temperature probes should

not stop the defrosting cycle prematurely but only prevent overheating. e probes must be placed in the coldest parts

of the heat exchanger (where there is the greatest frost formation) and at a distance from the heating elements.

TC 6.14

Make sure that at the end of each defrosting cycle (electric, hot gas or warm glycol), the finned pack, the internal

drip tray and the drain dischargers are clean. If necessary, correct the timing and the number of the defrosting cycles.

Accumulations of frost tend to turn into harmful ice accumulations that may cause malfunctioning or the failure of

the heat exchanger.

TC 6.15

Install the appropriate siphons on the drain discharge line and verify their effectiveness at all operating temperatures.

In low temperature rooms functioning below the freezing point, the external moisture entering from the discharge

line, if not provided with siphons, generates harmful ice accumulations.

TC 6.16

Access to the installed unit, for any type of intervention, should be reserved to experienced personnel specically trained to

run the system, in compliance with current regulations.

TC 9. Wiring and absorption diagrams

of fanmotors

TC 9.1

The casing of each unit is equipped with a ground terminal (PE9) with an identification label. It is mandatory to

connect the ground terminal of the unit to the external conductor or protective earthing system.

TC 9.2

In the units with wired fanmotors it is mandatory to connect the protective conductors of the fanmotors to the external

conductor or protective earthing system.

TC 9.3

It is mandatory to use protection systems against electric shock and equipment protection devices on the supply

lines of the fanmotors. The fanmotors are equipped with thermal contacts normal closed inserted in the windings

of the motor. Connect the thermal contacts to protect the engine from overheating. Please be aware that an over-

temperature can also be not directly caused by an overcurrent.

Please be aware that the thermal contact closes itself when the temperature decreases without a manual reset.

TC 9.4

Strictly follow the wiring diagrams to avoid damaging the motors (a,b,c,d,e).

TC 9.5

For models fitted with non standard fanmotors please refer to the diagrams and absorptions indicated in the

supplementary sheets and the rating plate.

TC 9.6

Before using any fanmotor speed control system check its compatibility with the fanmotors. Non-compatible systems

may generate noise and damages. The Manufacturer does not accept any responsibility regarding the performance of

the units equipped with speed controllers not defined during the offer.

TC 4. Destinazione d'uso

TC 4.1

Il modello deve essere utilizzato esclusivamente per lo scopo di seguito indicato altrimenti, l’uso è da considerarsi

improprio ed esonera il costruttore da qualsiasi responsabilità conseguente.

TC 4.2

Gli aeroevaporatori o aerorefrigeratori industriali della serie DFX DFB DFN e DFC sono progettati per essere utilizzati in

tutti i settori alimentari, nelle medie e grandi celle frigorifere o magazzini refrigerati, per la conservazione del prodotto

fresco e congelato e anche per il rarescamento e condizionamento di medie e grandi sale di lavorazione. Tutte le unità

standard sono equipaggiate con gruppo ventilante ad alta ecienza per un'ottimale distribuzione dell’aria.

TC 4.3

Il modello standard è equipaggiato con motoventilatori non adatti a sopportare prevalenze statiche aggiuntive come

quelle dovute a canalizzazioni, tunnel di abbattimento, etc..

TC 4.4

In caso di dubbio sulla destinazione d'uso contattare il Costruttore.

TC 5. Ispezione, movimentazione e trasporto

TC 5.1

Al ricevimento del modello controllare lo stato di integrità dell'imballaggio e del prodotto; contestare subito al

trasportatore qualsiasi danno eventuale verificatosi. L’imballaggio è fabbricato conformemente al modello, agli

adeguati mezzi di trasporto e di movimentazione.

TC 5.2

Durante il trasporto e la movimentazione del modello nel suo imballaggio, evitare sollecitazioni non conformi

e improprie sul prodotto imballato, attenersi a tutte le indicazioni illustrate e mantenere il modello sempre nella

posizione indicata in figura (Fig.1).

TC 5.3

Durante il trasporto e la movimentazione del prodotto imballato, utilizzare apposite protezioni per evitare di ferirsi

con le parti dell’imballaggio come chiodi, tavole o cartone e le parti del modello come le alette o la carrozzeria (vedi

DPI manuale tecnico sezione I cap IG 6).

TC 5.4

Disimballare il modello il più vicino possibile al luogo di installazione (vedi anche installazione e messa in opera). In

generale il modello non deve essere trasportato o movimentato privo dell’imballaggio originale.
