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 connected
to 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-off 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 REPRESENT A HAZARD FOR THE
USER.

IDENTIFICATION OF THE UNIT

The air treatment units come with a rating plate, which shows:

- The manufacturer's address; - Supply voltage in "V";

- "CE" marking; - Supply frequency in “Hz”;

- Model; - Number of phases, indicated with "Ph";

- Lot number; - Total cooling capacity in “W”;

- Date of production; - Sensible cooling capacity in “W”;

- Rated absorbed current in "A"; - Heat output.

- Input in “W”;

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

Secure packs during transportation.
Do not expose to the elements.
Do not tread on packs.

Protect hands with work gloves when dismantling the unit.
Work in PAIRS if the appliance weighs more than 25 kg.

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 Pic. 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.

Drill the holes in line with the relative slots for the 6 unit screw anchors (Pic.

4). Inject thermosetting resin into the holes and then insert the screw anchors
(Pic. 5).

Fix the threaded rods of the correct length to the screw anchors (Pic. 5) and
insert them into the relative slots (Pic. 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 possible noise being created by vibrations from the
unit, it is advisable to insert a vibration-damping joint.

Note: the screw anchors, threaded rods and whatever else is necessary
for accomplishing the installation are NOT included in the supply of the
air treatment unit.

INSTALLATION OF THE AIR TREATMENT UNIT

PRELIMINARY OPERATIONS

- check that the various unit components are perfectly intact;

- check that the installation accessories and documentation are in the pack;

- place the packed section as close as possible to the place of installation;

- Do not place tools or weights of any kind on the packed unit.
