IMPORTANT: OMNIA fan coils
are designed for indoor use.
IMPORTANT: check that the
power supply is disconnected before
carrying out any procedures on the
unit.
WARNING: before carrying out
any work, put the proper individual
protection equipment on.
IMPORTANT: the device must be
installed in compliance with national
plant engineering rules.
IMPORTANT: the electrical
connections, plus the installation of
fan coils and relevant accessories,
should only be performed by a
technician with the necessary
technical and professional expertise
to install, modify, extend and
maintain systems, and who is able to
check the systems for purposes of
safety and correct operation (in this
manual such technicians will be
indicated with the general term
"personnel with specific technical
skills").
In the specific case of electrical
wirings, the following must be
checked:
- Measurement of the electrical system
insulation strength
- Continuity of the protection wires
IMPORTANT: Install a device,
main switch, or electric plug so you
can fully disconnect the device from
the power supply.
The essential indications to install the
device correctly are given here.
The installer's experience will be
necessary however, to perfect all the
operations in accordance with the
specific requirements.
The water, condensate discharge
and electrical circuit ducts must be
provided for.
The fan coil should be installed in such
a way as to facilitate routine (filter
cleaning) and special maintenance
operations, as well as access to the
air drain valve on the side of the unit
frame (connections side).
Do not install the unit in rooms where
there are inflammable gases or
acid/alkaline substances which can
provoke irreparable damage to the
copper-aluminium heat exchangers or
internal plastic components.
Do not install the unit in workshops
or kitchens, where oil vapours mixed
with the treated air can be deposited
on the exchange coils (reducing their
effectiveness) or on the internal parts
of the unit (damaging the plastic
components).
The fan coil must be installed in such a
position that the air can be distributed
throughout the room and so that there
are no obstacles (curtains or objects)
to the passage of the air from the
suction louvers.
You are advised not to install the
fan coil above objects that suffer
from damp or wet because in some
conditions condensation may form on
the external frame of the equipment
with the possibility of dripping or
failures may occur in the hydraulic
system and condensate drainage with
the consequent spilling of liquid.
The assembly site must be chosen in
such a way that the maximum and
minimum ambient temperature limits
are respected 0-45°C (<85% R.H.).
