ROOM FAN COIL UNITS 42N
Main drain pan and insulation
■■ The main drain pan incorporates innovative technological
solutions:
-- Horizontal installation: the units can be installed
perfectly horizontal - the drain pan structure takes
care of the slope, so that the installer avoids complex
and time-consuming computations to correctly install
the units.
-- Left or right-hand condensate connection is standard
- the installer can easily choose unit connection on
one side or the other, just by fixing the plastic cap on
the opposite side.
-- Insulation: the drain pan design allows much tighter
contact between drain pan and insulation, reinforced
by metal clips to keep the insulation in place. This
improves reliability and prevents water dripping from
the unit.
-- The drain pan for the whole range is made of moulded
plastic, i.e. more robust, easier and safer to service.
PTC electric heater
■■ Electric heater options have been enhanced with the
latest PTC (positive temperature coefficient) technology.
Their resistance increases as their temperature increases,
so the capacity goes down accordingly. This electric
heater feature allows fast heating at start-up, the heating
capacity is adjusted automatically, whilst ensuring safe
and reliable operation. This option is available in low and
high capacity for each Idrofan size.
Feet mounting
■■ The installation of feet has been greatly simplified and
both sides are painted. Just one clip is needed to fix the
feet to the units. For this reason and for better reliability
during transport, the feet are sold as options - supplied
with the unit from the factory (ordering codes Z or P in the
4th digit). They are included with the unit, but not factorymounted.
Simplified accessories
■■ The number of accessories has been reduced to simplify
selection and reduce the inventory level. The accessories
offered remain unchanged to satisfy any application
needs, but the number of codes has been greatly
reduced.

AIR TREATMENT
■■ If the unit received is not as required, the coil and the
control box can be switched on site from left to right or
vice versa (except units equipped with valves - since their
installation is optimised for each side, the valve package
must be replaced by a new valve kit).
