Average minimum water temperature
To prevent the formation of condensation on the exterior of the unit while the fan is operating, the average water temperatu-
re should not drop beneath the limits shown in the table below, determined by the ambient conditions.
These limits refer to unit operation with fan at minimum speed.
OPERATING LIMITS
WARNING: The fan coil 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.
MALFUNCTIONING
In the case of malfunctioning remove the power to the unit
then repower it and start the apparatus up again. If the
problem occurs again, call your areas After-Sales Service
promptly.
POWER THE FAN COIL ONLY WITH 230 VOLT, SINGLE
PHASE, 50 HZ
Use of other power supplies could cause permanent damage
to the fan coil.
USE THE (TLW1) REMOTE CONTROL UNIT OR THE WIRED
REMOTE PANEL (PFW) TO TURN THE FAN COIL ON AND
OFF
Do not turn the fan coil on or off using the auxiliary switch
unless it is an emergency.
DO NOT TUG THE ELECTRICAL CABLE
It is very dangerous to pull, tread on or crush the electrical
power cable or fix it with nails or drawing 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.
DO NOT USE THE FAN COIL IMPROPERLY
Do not use the fan coil in animal husbandry applications
(e.g. incubation).
AIRING THE ROOM
Periodically air the room in which the fan coil 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.
CORRECTLY REGULATING THE TEMPERATURE
The room temperature should be regulated in order to
provide maximum comfort to the people in the room,
especially if they are elderly, children or ill, avoiding sudden
changes in temperature between the outside and inside above
7 °C in summer.
Careful choice of the room temperature will lead to energy
savings.
CORRECTLY ADJUSTING THE AIR JET
The area coming out of the fan coil must not strike people
directly; in fact, even if at a temperature that is higher than
the room temperature, it could cause a cold sensation and
resulting discomfort. Only adjust the vertical slats by hand.
For the horizontal air delivery deflector, use the LOUVRE
key of the remote control unit or SWING key on the wired
remote panel.
DURING OPERATIONS
Always leave the filter on the fan coil during operation
(otherwise dust in the air could soil the coil surface area).
WHAT IS NORMAL
During cooling function, water vapour may be present in the
air delivery.
In heating function it might be possible to hear a slight hiss
around the fan coil. Sometimes the fan coil might give off
unpleasant smells due to the accumulation of dirt in the air
of the environment (especially if the room is not ventilated
regularly, clean the filter more often).
IMPORTANT INFORMATION
The assembly site must be chosen in such a way that the
maximum and minimum ambient temperature limits Ta are
respected 0°C < Ta < 45°C ; R.H. < 85%.
The fan coils are powered with a voltage of 230 V monophase
at 50 Hz and ground connection, in any case the power of
the line must remain within the limit of ±10% with respect to
the nominal value.
