IMPORTANT INFORMATION
WARNING:
The OMNIA fan coil units are designed for inter-
nal installation.
WARNING: The fan coil unit is connected to the
power supply and a water circuit. Operations
performed by persons without the required
technical skills can lead to personal injury to the
operator or damage to the unit and surrounding
objects.
WARNING: Components sensitive to static elec-
tricity can be damaged by voltages well below
human perception. These discharges occur when
touching a component or electrical contact with-
out first discharging the body of any accumu-
lated electrical charge. The damage caused by
static discharge is not immediately perceptible
and may manifest only after a certain period of
operation.
ACCUMULATION OF STATIC ELECTRICITY
Any person without a conductive connection to
the ambient electrical potential can accumulate
static electricity.
BASIC PROTECTION AGAINST ELECTROSTATIC
DISCHARGES
Quality of earthing
When operating on units sensitive to static elec-
tricity ensure that the person, the workplace and
the covers of the unit are correctly earthed. In this
way the formation of static charges is avoided.
Avoid direct contact
Only touch the exposed sensitive parts if abso-
lutely necessary, such as during maintenance.
Do not touch the contact pins or printed circuit
board. By following this advice the electrostatic
discharge cannot reach or damage the sensitive
parts.
If measurements have to be taken from the unit
it is important to electrically discharge the body
Aermec cod. 6976420_00 13.05
before carrying out any operation, by touching
a metal object connected to the earth. Only use
earthed instruments.
POWER THE FAN COIL UNIT ONLY WITH 230
VOLT SINGLE PHASE
Use of other power supplies could cause perma-
nent damage to the fan coil unit.
DO NOT USE THE FAN COIL UNIT IMPROPERLY
Do not use the fan coil unit in animal husbandry
applications.
VENTILATE THE ROOM
Periodically air the room in which the fan coil unit
has been installed; this is particularly important
if the room is occupied by many people, or if gas
appliances or sources of odours are present.
C O R R E C T L Y C O N T R O L L I N G
TEMPERATURE
The room temperature should be controlled in
order to provide maximum comfort to the people
in the room, especially if they are elderly, chil-
dren or ill, avoiding sudden changes in tempera-
ture between the outside and inside above 7 °C in
summer.
Lower temperature in the summer means higher
electrical consumption.
CORRECTLY ADJUSTING THE AIR JET
The air coming out of the fan coil unit must not
strike people directly; in fact, even if at a tempera-
ture that is higher than the room temperature,
it could cause a cold sensation and resulting dis-
comfort.

DURING OPERATION

Always leave the filter in the fan coil unit during
operation otherwise dust in the air will dirty the
surfaces of the coil.
WHAT IS NORMAL
During cooling, water vapour may be present in the
air discharge.
During heating it might be possible to hear a slight
hiss around the fan coil unit. Sometimes the fan
coil unit might give off unpleasant smells due to the
accumulation of substances from the air of the room
(especially if the room is not ventilated regularly.
Clean the filter more often).
During operation, there could be noises and
creaks inside the device, due to the thermal
expansion of the various components (plastic and
metallic), but this does not indicate a malfunction
and does not cause damage to the unit unless the
maximum inlet water temperature is exceeded.
MALFUNCTIONS
In the case of a malfunction remove power to
the unit then reapply it and start the unit again.
If the problem occurs again, call your area After-
Sales service department promptly.
T H E
DO NOT PULL THE ELECTRICAL CABLE
It is very dangerous to pull, tread on or crush the
electrical power cable or fix it with nails or draw-
ing pins.
A damaged power cable can cause short circuits
and personal injury.
DO NOT PUT ANYTHING IN THE AIR OUTLETS
Do not put anything at all in the air outlet slots.
This could cause injury to people and damage to
the fan.
