CHAPTER 1: GENERAL POINTS

1.1 INTEDED USE AND MODEL VERSION

The Fral Dehumidifier is intended exclusively for air Dehumidifier via a steam vapouration or a

ventilation unit approved by the manufacturer within the specified operating conditions. Any other

type of application without the express written consent of the manufacturer is considered as not

conforming to the intended purpose and may lead to Fral becoming dangerous.

Operation of the equipment in the intended manner requires that all the information in these

installation and operating instructions is observed (In particular the safety instruction).

FD 360

Standard Version (mod. FD 360)

Hot Gas Defrost (mod. FD 360/S)

Hot gas Defrost + Electric Heatres (mod. FD360S+4kW)

Both models are also available in DEHU-CLIMA versions see other specific manual.

All models can be configured with in-line airflow or top airflow (see chapter 10).

1.2 UTILITY AND CONSERVATION OF THE MANUAL

This Manual conforms to the requirements of the Norms 98/37/CE and subsequent modifications.

The Manual gives all necessary indications required for the transport, Installation, start-up and

maintenance of the machines, which must be strictly followed by the user for a correct functioning of

the same.

To this purpose, the user must also strictly comply with the security norms described in the Manual.

The manual must always follow the machine and must be kept in a place which will guarantee its

perfect conservation for the proper use from the operator.

GRAPHIC SYMBOLS AND INDICATIONS INCLUDED IN THE MANUAL:

shows that ATTENTION must be paid to all procedures and operations to be carried out

for ensuring the correct functioning of the machine, describes the operations that mus

be avoided , and finally informs the operator about the correct procedure and

operations to be followed for the proper use of the machine.

1.3 NORMS REFERENCES

The machines described in this manual hav been designed according to the pertinent CE Norms, in

conformity with the MACHINES DIRECTIVES cited in the previous paragraph.

The machines are also complying with the essential requirements of the following European Rules and

Directives:

Machine Safety Norms 89/392 CEE,

Electrical Safety Rules for the Low Tension Appliances 2006/95 CEE,

Electromagnetic Compatibility Norms2004/108 CEE,

Under Pressure Devices 97/23/CE.

1.4GENERAL SAFETY NORMS

When installing or servicing the unit, it is necessary to strictly follow the rules reported on this manual,

to conform to all the specifications of the labels on the unit, and to take any possible precautions of

the case for workers.

Pressure in refrigerant circuit and electrical equipment present in the unit can be hazardous when

installing or servicing the unit

Therefore, all operations on the unit must be done only by trained people.

Not observing the rules reported on this manual, and every modification to the unit done

without explicit previous authorisation, will cause the immediate termination of the

warranty.

Attention: before every operation of servicing on the unit, be sure that the

electric supply is disconnected.

Close to the unit a switched electrical plug must be present.

Main supply must be protected with a differential switch.

Never modify settings of the safety devices.

Never sprinkle water over the unit and its electrical components.

This uni

must It must not be used under explosive atmosphere

CHAPTER 2: INSPECTION, TRANSPORT AND SITE HANDLING

2.1 INSPECTION

After receiving the unit, immediately check its integrity. The unit left the factory in perfect condition;

any eventual damage must be questioned to the carrier and recorded on the Delivery Note before it

is signed. Our firm must be informed, within 8 days, of the extent of the damage.

The Customer must prepare a written statement of any severe damage.

2.2 LIFTING AND SITE HANDLING

The lifting is obtained by using a forklift: fork must be inserted in the base pallet, and care must be

taken in order that the fork does not hit the section base or panel (see the picture below).

To unload the unit with a crane, pass bars under the machine and attach the necessary cable or chain

lifting devices to the bar, ensuring that they are clamped firmly; protect the sides of the chiller with

boarding or material of a similar nature.

2.3 UNPACKING

When unpacking the unit pay attention not to damage the unit.

The package is made up by different materials: wood, paper, nylon etc.

It’s a good rule to keep them separately and deliver to the proper collecting centre in order to reduce

their environmental impact.

2.4 LOCATION

Consideration must be given to the following points when determining the most suitable site/location for the

unit installation:

location arrangement in order to guarantee adequate air flow (no narrow spaces)

electrical power supply location;

accessibility for servicing/maintenance and repair of the unit and/or its components;

floor loading strength and ability to support the operating weight of the unit;

Possible objection to operating noise.

CHAPTER 3: INSTALLATION

3.1 CLEARANCES

Absolute care must be taken to ensure adequate air volume to the air intake and fan discharge, and to avoid air

recirculation through the unit that will deeply reduce its performances.

For these reasons it is necessary to observe the following clearances (see the pictures in the following pages):

- air folter suction side: 0,5 mt min.

- fan side: 0,8 mt min.

- electric board side: 0,8 mt min.

- top side: 0,2 mt min.

3.2 ELECTRICAL CONNECTIONS

3.2.1 Generality

Before every operation on the electric section, be sure that the electric supply is disconnected.

Main supply must be protected with a differential switch

Close to the unit a main switch must be present.

It must be verified that electric supply is corresponding to the unit electric nominal data (tension, phases,

frequency) reported on the label in the front panel of the unit.

Power connections must be made using a three-wire cable + neutral wire + ground cable.

Power cable and line protection must be sized according norm and laws according with

absorbed current of the machine (see technical data).

The line voltage fluctuations must not be more than ±5% of the nominal value, while the voltage unbalance

between one phase and another must not exceed 2%. If those tolerances should not be respected, please

contact our Firm to provide proper devices.

Electric supply must be in the limits shown: in the opposite case warranty will terminate

immediately.

Electrical connections therefore must be always done according to the instructions reported on

the wiring diagram enclosed with the unit and norms and laws.

Ground connection is compulsory. Installer must connect ground cable with a dedicated terminal on the

apposite terminal block.

3.2.2 Main supply connection

The Electric Power Supply Connection must be carried out according to the indications given in the Electric

Diagram, by connecting the cable supplied with the machine and according with safety norm.

Models FD360 must be electrically powered with 3 phase-neutral-earths.

The compressor has only one allowable rotation direction; therefore, the machine has a control device for

the phases sequence; in case that it may show a wrong sequence, the device inform you with a blinking light;

in this case two phases must be interchanged.

Pay much attention to above indications because the compressor will be damaged if the rotation direction is

not correct.
