with local regulations in force.

Follow local safety regulations.

Verify that the electrical line characteristics are in compliance with data quotes on the unit serial number label.

1.6 Maintenance

Plan periodic inspection and maintenance in order to avoid or reduce repairing costs.

Turn the unit o before any operation.

1.7 Modication

All unit modications will end the warranty coverage and the manufacturer responsibility.

1.8 Breakdown/Malfuction

Disable the unit immediately in case of breakdown or malfunction.

Contact a certied service agent.

Use original spares parts only.

Using the unit in case of breakdown or malfunction:

•voids the warranty

•it may compromise the safety of the unit

•may increase time and repair costs

1.9 User training

The installer has to train the user on:

•Start-up/shutdown

•Set points change

•Standby mode

•Maintenance

•What to do / what not to do in case of breakdown

1.10 Data update

Continual product improvements may imply manual data changes.

Visit manufacturer web site for updated data.

1.11 Indications for the User

Keep this manual with the wiring diagram in an accessible place for the operator.

Note the unit data label so you can provide them to the assistance centre in case of intervention (see“Unit identication” section).

Provide a unit notebook that allows any interventions carried out on the unit to be noted and tracked making it easier to suitably note the

various interventions and aids the search for any breakdowns.

In case of breakdown or malfunction:

•Immediately deactivate the unit

•Contact a service centre authorized by the manufacturer

The installer must train the user, particularly on:

•Start-up/shutdown

•Set points change

•Standby mode

•Maintenance

•What to do / what not to do in case of breakdown

1.12 Unit indentication

The serial number label is positioned on the unit and allows to indentify all the unit features.

The matriculation plate must never be removed.

The matriculation plate shows the indications foreseen by the standards, in particular:

•unit type

•serial number (12 characters)

•year of manufacture

•wiring diagram number

•electrical data

•manufacturer logo and address

1.13 Serial number

It identies uniquely each unit.

Must be quoted when ordering spare parts.

1.14 Assistance request

Note data from the serial number label and write them in the chart on side, so you will nd them easily when needed.

2 Reception

You have to check before accepting the delivery:

•That the unit hasn’t been damaged during transport

•That the materials delivered correspond with that indicated on the transport document comparing the data with the identication label

positioned on the packaging.

In case of damage or anomaly:

•Write down on the transport document the damage you found and quote this sentence: “Conditional acceptance clear evidence of

deciencies/damages during transport”

•Contact by fax and registered mail with advice of receipt to supplier and the carrier.

Any disputes must be made within 8 days from the date of the delivery. Complaints after this period are invalid.

2.1 Storage

Observe external packaging instructions.

2.2 Handling

•Verify unit weight and handling equipment lifting capacity.

•Identify critical points during handling (disconnected routes, ights, steps, doors).

•Suitably protect the unit to prevent damage.

•Align the barycenter to the lifting point

•Use all the lifting brackets (see the dimensional section)

•Gradually bring the lifting belts under tension, making sure they are positioned correctly.

•Before starting the handling, make sure that the unit is stable.

A Supports for handling: remove after the handling.

B Protections

C Additional lifting brackets

3 Positioning

During positioning consider these elements:

•Technical spaces requested by the unit

•Electrical connections

•Water connections

•Spaces for air exhaust and intake

3.1 Functional spaces

Functional spaces are designed to:

•guarantee good unit operation

•carry out maintenance operations

•protect authorized operators and exposed people

Respect all functional spaces indicated in the DIMENSIONS section.

Double all functional spaces if two or more unit are aligned.

3.2 Positioning

Units are designed to be installed:

•INTERNAL

•in xed positions

Limit vibration transmission:

•use antivibration devices on unit bearing points

•install exible joints on the hydraulic connections

Choose the installation place according to the following criteria:

•Customer approval

•safe accessible position

•technical spaces requested by the unit

•spaces for the air intake/exhaust

•max. distance allowed by the electrical connections

•Avoid installations in places subject to ooding

•verify unit weight and bearing point capacity

•verify that all bearing points are aligned and leveled

•install the unit raised from the ground

A correct circulation of the air is mandatory to guarantee the good unit operating.

Avoid therefore:

•obstacles to the airow

•diculty of exchange

•leaves or other foreign bodies that can obstruct the air coil

•winds that hinder or favour the airow

•heat or pollution sources close to the unit (chimneys, extractors etc..)

•stratication (cold air that stagnates at the bottom)

•recirculation (expelled air that is sucked in again)

Ignoring the previous indications could:

•reduce energy eciency

•alarm lockout due to HIGH PRESSURE (in summer) or LOW PRESSURE (in winter)

3.3 Saftey valve gas side

The installer is responsible for evaluating the opportunity of installing drain tubes, in conformity with the local regulations in force (EN 378).

3.4 Fresh air probe

M02S40N16-00

3.5 Air channelling

When designing and manufacturing the ducting, consider LOAD LOSSES, AIR FLOW AND SPEED that must be consistent with the unit features.

Limit the load losses by optimising the path, the type and number of bends and junctions.

Consider that excessive external static pressure will lead to a reduction in ow rate, with consequent alarm lockout.

Ensure ducts are thermally insulated.

The weight of the ducting must not burden the connection anges.

Place anti-vibration joints between channels and unit.

Connection to the anges and between the various sections of the channels must guarantee air seal, avoiding dispersions penalising the

overall eciency of the system.

Vertical outlet standard (1)

Rear outlet option (2)

Provide:

•water discharge (3-A)

•grilles to restrict access to small animals (3-B)

•deectors (3-C) to avoid the by-pass between the two air ows

•safety grille (4-D)

Avoid therefore:

•angle curves and narrowings (5)

•direct air ow on people (6-7), windows, doors, plants, obstacles in general

•obstacles that prevents the air inow to the coil (8-9)

•installations next to silent rooms
