INTRODUCTION

This installation and maintenance booklet should always accompany the
air treatment unit for ready consultation by the installer or user if necessary.
The unit should be installed in compliance with the regulations in force
in each country and according to the manufacturer's or qualified person's
instructions. The manufacturer cannot be held liable for any damage to
property or injury to persons and animals caused by incorrect installation
of the unit. Only qualified persons should install the unit and connect it
to the mains electricity supply. Before carrying out any work on the unit,
ensure that it is disconnected from the electricity supply. Read this
instruction booklet prior to installation.

RECOMMENDATIONS

This unit is easy to use, but it is important to read all the contents of this
guide before using it for the first time. This will help you to:

- use the unit in all safety

- obtain best performance

- avoid incorrect actions

- respect the environment

-

Do not allow children or unassisted handicapped persons to use the unit.

- Do not touch the unit with wet parts of the body or if barefoot.

- Do not tug, pull or twist electrical cables attached to the unit, even
when disconnected from the electricity supply.

- Do not open the flaps giving access to the internal parts of the unit
without having first put the system on-off switch to "off".

- Do not introduce sharp pointed objects through the air intake and outlet grilles.

- Do not leave packing material (boards, staples, plastic bags, etc.)
within reach of children since they could be a source of danger.
Dispose of correctly.

- Do not spray or throw water directly on the unit.

- Do not use the unit in places with suspended dust/powder or in
potentially explosive atmospheres, in very damp environments or in
the presence of oil in suspension or in particularly aggressive
atmospheres.

- Do not cover the unit with objects or drapes that even partially obstruct
the air flow.

The unit works by electricity at mains voltage (230 Vac, 50 Hz). Always bear
in mind that mains voltage is potentially dangerous and any appliance
connectedto it should be used with caution. Before carrying out any work
on the unit, disconnect it from the electricity supply (by pulling out the plug
from the mains socket or isolating the supply line by putting the on-of switch
OFF. If the unit is not be used for long periods, make sure that the controls

are in the position 0 (off). If the unit is not going to be used in winter when
temperatures are near to freezing, drain the system and ensure that the
unit heat exchanger has no water in it in order to prevent the formation of
ice and consequent breakage. To make the unit inoperable, disconnect it
totally from the electricity supply. It is unsafe to alter or try to alter the
characteristics of this product. Any tampering or alteration in any case makes
the warranty null and void. In the event of malfunction or failure, do not try
to repair the unit yourself; contact a qualified technician. Repairs carried out
by incompetent persons could cause damage or accidents. Always keep
the unit clean. In particular clean the air filter periodically (at least once a
month).

FAILURE TO COMPLY WITH THE ASSEMBLY INSTRUCTIONS

!

GIVEN IN THIS GUIDE RELIEVES THE PRODUCER OF ALL AND
ANY LIABILITY. INCORRECT INSTALLATION COULD CAUSE
MALFUNCTIONING OR FAILURE OF THE UNIT. IT COULD ALSO

TRANSPORTATION, RECEIVING, HANDLING

The units and their accessories are enclosed in cardboard boxes up to
size 50, while the other sizes are palletised. The packs should be kept
intact until positioned in the final place of installation. Use suitable
handling equipment according to the weight of the unit, as provided for
by directive 89/391/EEC and subsequent amendments. The weight of
each single machine is given in this guide (table 2). Upon receiving the
unit, check all the parts for any damage caused in transit. Any damage
should be reported to the carrier by affixing an accepted with reservation
on the accompanying note, specifying the type of damage. In the event
of prolonged storage, keep the units protected against dust and far from
sources of vibration or heat. The number of units that may be positioned
on one pallet are given in the table (table 1).

THE PRODUCER CANNOT BE HELD LIABLE FOR DAMAGE

!

DUE TO INCORRECT HANDLING OR LACK OF PROTECTION
AGAINST THE ELEMENTS.

SAFETY PROVISIONS

UNIT INSTALLATION

RECOMMENDATIONS FOR INSTALLATION!

Before installing the unit, ensure that:

1) the place of installation has sufficient space for carrying out installation as well as routine

and extraordinary maintenance work (see fig. 3). If the unit is installed behind a
suspended ceiling, an access should be provided;

2) there are no obstructions for air intake and delivery;

3) the water fittings are of the sizes, in the position and spaced apart as required by the

unit;

4) the system pressure does not exceed 8 bar for the water-filled versions;

5) the electricity supply corresponds to the data on the unit rating plate and that there is

a circuit breaker switch readily accessible to the user to cut off the power supply
whenever necessary;

6) the circuit breaker is in the OFF position so that there is no voltage on the unit supply

line.

INSTALLATION OF THE ACCESSORIES

Some examples are given below of assembling the accessories for ducted air
treatment units.

Example 1

First of all put the air filter section (SFA) on the unit intake, inserting it into the special
rim (male-female) and fixing it with the galvanised self-tapping screws 4.2x9.5.
Proceed as described above on the delivery end with the connecting flange (FAM).
Put the vibration isolation joint (GAM) on the flange and fix it using the cheese­headed screws M8x16 and hexagon bolts.

Drill the holes in line with the relative slots for the 6 unit screw anchors (fig. 4). Inject
thermosetting resin into the holes and then insert the screw anchors (fig. 5).

Fig. 5

Fix the threaded rods of the correct length to the screw anchors (fig. 5) and insert them
into the relative slots (fig. 6). After having created a slope (max. 3 cm/m) in the direction
of the condensate outlet, lock the threaded rod with a nut and check nut. To prevent

Example 2

Proceed by inserting the manual air intake section (SSP) into the air filter section (SFA) by
means of the male-female coupling. After having secured it with the self-tapping screws (4.2
x 9.5 galvanised), anchor it to the ceiling as illustrated for the base unit in figures 4-7. Put
another connecting flange on the vibration isolation joint (GAM) and secure it using cheese­headed screws M8x16 and hexagon bolts. Insert the straight delivery plenum (PAM) in the
connecting flange and fix it using galvanised self-tapping screws 4.2 x 9.5. Connect the air
delivery union with round fittings (BAM) with the procedure described above.
