Installation, operation and maintenance / INALTO-IOM-1809-E
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 qualifi ed 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 qualifi ed 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 fi rst 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 fl aps giving access to the internal parts of the unit with-
out having fi rst 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 fl ow.
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 qualifi ed technician. Repairs car-
ried out by incompetent persons could cause damage or accidents. Always
keep the unit clean. In particular clean the air fi lter 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.
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 fi nal 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 affi xing 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 INSTRUCTIONS

RECOMMENDATIONS FOR INSTALLATION
Before installing the unit, ensure that:
1) The place of installation has suffi cient space for carrying out installa-
tion as well as routine and extraordinary maintenance work (see Figure 03). 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 fi ttings 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-fi lled ver-
sions;
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 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.
Drill the holes in line with the relative slots for the 6 unit screw anchors
(Figure 4).
Inject thermosetting resin into the holes and then insert the screw anchors
(Figure 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.
