4.5 - Filters
Removable filters.
The guaranteed efficiency degree is from G3 and F9 (CEN EN 779,
corresponding to EU3 and EU9 according to Eurovent EU4/5).
The folded structure of the filters gives high filtration efficiency and
low pressure drop.
The filter media used consists of synthetic fibre cells. The frame is
made of cardboard.
Pre-filtration system for Over models.
4.6 - Refrigerants
The units are designed for being used with refrigerant R22 or, as optional, R407C.
4.7 - Electric board
The electric board is housed in the front part in a space insulated against
the air flow and protected by a plastic crankcase, so as to avoid tamper
ing by non-authorized personnel and to protect the electric board parts
supplied with a voltage higher than 24 V.
The electric board complies with the norm 204-1 IEC.
The air conditioners have been provided for operating at 400 V/3/50
Hz+N+G (as special alternative execution, the version with 220V/3/50Hz
+ G can be supplied) and at 380 V/3/60 Hz+N+G and 230 /3/60 Hz+G.
Magnetothermal switches are supplied as protection of every electric component.
A single-phase transformer has been provided for supplying power to the secondary circuit at 24 V.
A main switch with door-locking handle is installed in series on the safety crankcase to prevent it from
being removed when the switch is in the operating position.
There will be an automatic start-up after a possible stop due to power supply lack.
Additional terminals for remote start-up and carry of some operating conditions (fans and compressors)
or connection of additional devices (Liquistat, Firestat, Smokestat, clogged filters) are set in series on the
terminal board of the electric board. On the terminal board there is also a clean contact for the remote
signalling of the general alarm.
4.8 - Accessibility
Having access to the compressor is possible even when the unit
is operating by removing the front panel. The access to the fan is
executed with the greatest care for easier interventions (mainte
nance and/or fan replacement).
4.9 - Control system
Very simple user interface.
Immediately intelligible utilization of the control unit system with
LCD.
Net connectivity of several units.
Possible utilization of the Hiromatic graphic terminal.
