RECEIVING AND HANDLING THE PRODUCT
The fan coils come in single packs protected by a cardboard
box.
It is advisable to remove the packaging only when the
appliance has been located near the point of installation.
After the packaging has been removed, the fan coil must
be handled manually by suitably equipped, qualified per-
sonnel and in compliance with accidentprevention
norms.
PROJECT SPECIFICATIONS
PROJECT SPECIFICATIONS CHD U-2T
Frame in galvanised steel insulated with self-extinguishing
closed-cell polyethylene blanket of suitable thickness to limit
heat loss and noise to a minimum. Airflow grille in PS. Man-
ual louvers as well independent adjustable for vertical air-
flow direction. All the main parts can be easily accessed
through the grille. Regenerative air filters. Accident-preven-
tion grille over the fan intake.
Coil with corrugated aluminium fins and copper pipes, 100%
tested with dried air at 14 bar. 4-speed electric motor inclu-
sive of thermal switch. Low-rev radial-blade fan to maximise
acoustic comfort. Hydraulic connections. Manual air valve
with outlet connected to the condensate collecting tray.
Plastic condensate collecting tray housing the condensate
drain pump and float. Condensate drain pump with 650 mm
working head and 24 dB(A) noise level. Float for conden-
sate drain pump operation control and to warn of overflow
obstruction. Switchboard with power and control terminal
block with screw terminals.
Set-up for fresh air intake. Set-up for duct air distribution.
Set-up for cladding of air outlets. Ceiling-mounting brackets.
Hydronic cassette universal version connected with wall-
mounted thermostat.
Other technical data
All other important technical data (dimensions, weights, con-
nections, noise emissions, etc.) are given elsewhere in this
User and Installation manual.
The operating and installation manual are considered
part of the appliance and must therefore be read careful-
ly and kept for reference.
The fan coil must be handled by equipped qualified per-
sonnel using suitable equipment for the weight of the
appliance.
Take care when removing the adhesive strips from the
appliance.
Packaging components must be disposed of correctly
and not left within reach of children since they are a
potential source of danger.
