INSTALLATION
VORT LETO MEV HCS is compatible with installation
in differing types of buildings whether new or existing.
They can be mounted vertically, horizontally or
inclined, in false ceilings, on mezzanines, on ceilings,
etc. The appliance can be fixed in position by using the
slots on the base.
During the installation procedure, the instructions in
this booklet must be followed carefully and all current
legislation complied with:
NB: before carrying out any
operation it is necessary to
disconnect the power supply.
NB: in the case of speed settings
using a trimmer, precautions must
be taken against the possibility of
electric shock. Adjustment
operations must be carried out by
a competent person.
INITIAL SETTING OF SPEED
Removing the upper cover
Undo the fixing screw (fig.3) and use the lever to
remove the cover. (fig 4)
Adjusting trimmers
The circuit board fitted on the VORT LETO MEV HCS
range device is equipped with two trimmers, “RV1” and
“RV2”, for setting the minimum (Vmin) and maximum
(Vmax) values, respectively ((for the calculation of the
average speed, see the dedicated paragraph at page
19).
The values that can be set for these speeds are:
• Vmin: 400 rpm - current maximum speed minus 100
rpm
• Vmax: 600 - 2500 rpm.
NOTE:
Achievement of the required flow rate in each serviced
room requires simultaneous regulation of the motor
speed and of the degree of opening of the air inlets in
the rooms.
NOTE:
Increasing the speed of the motor leads to an increase
in power consumption and noise emission.
