USER MANUAL
Vers. 02 - 29/01/2016

INTRODUCTION
This manual includes the technical description, operation, installation and assembly instructions,
technical data for the PICO HP2 ventilation unit with energy regeneration, referred in this document
as the "ventilation unit".
The ventilation unit is designed to ensure air exchange in apartments, houses, hotels, bars and other
domestic and public buildings. The ventilation unit comes equipped with a ceramic heat exchanger
that allows air circulation due to the regeneration of energy with the heat of inowing air.
The ventilation unit is designed for mounting inside a wall.The telescopic design of the ventilation unit
allows it to be installed in walls from 300 mm to 500 mm thick.
The ventilation unit has been tested for continuous operation always connected to power mains.
The transported air must not contain ammable or explosive mixtures, chemical vapours, coarse dust,
soot and oil particles, sticky substances, brous materials, pathogenic organisms or other harmful
substances.
The ventilation unit is designed for installation indoors with the environment temperature ranging
from -20°C to +50°C and relative humidity up to 80%.
The ventilation unit design is regularly improved and some models may be slightly dierent to the one
described in this manual
THE FAN IS NOT INTENDED FOR USE BY CHILDREN, PEOPLE WITH PHYSICAL OR MENTAL
DISABILITIES, THOSE WITH SENSORY DISORDERS, AND/OR ANYONE WITHOUT SUITABLE
CAPABILITY.
THE OPERATIONS OF INSTALLATION AND CONNECTION MUST BE CARRIED OUT BY
QUALIFIED PERSONNEL AFTER RECEIVING PROPER SAFETY TRAINING.
THE SITES FOR INSTALLING THE UNIT SHOULD PREVENT ACCESS TO NON-SUPERVISED
CHILDREN.

OPERATION OF THE PICO HP2
CONSTRUCTION DETAIL
The ventilation unit consists of a xed-length circular air duct, a ventilation unit, and an outdoor grill.
The two motors, two lters and the exchanger are located within the inner duct.
Theltersaredesignedtopurifytheintakeairandpreventtheentry of objectsforeigntotheexchanger
and fans.
The ventilation unit generates an audible alarm to remind you to clean or replace the lter every 1,500
hours of operation.
The ceramic heat exchanger uses the heat energy in the extracted air to heat the incoming air ow.
The exchanger is equipped with a pull-cord inside to facilitate its extraction from the ventilator. The
heat exchanger is installed on an insulating material, used also as a sealant.
The ventilation unit must be installed on the inner side of the wall.
The outside grill must be installed on the wall exterior, to prevent water and other objects from
entering the ventilation unit.

INSTALLATION AND SETUP
1.To mount the ventilation unit, prepare a round through-
hole in the wall depending in the "Pico HP2 model" you
have purchased, having a 1° inclination downwards
towards the outside.
The size of the hole is shown in the gure below.
WARNING!
THE VENTILATION UNIT MUST NOT BE INSTALLED WHERE
THE AIR DUCT CAN BE BLOCKED BY SHUTTERS, BLINDS, ETC.
TO PREVENT DUST DEPOSITING AND ACCUMULATING. ALSO
CURTAINS MAY BLOCK THE NORMAL FLOW OF AIR IN THE
ROOM, MAKING THE UNIT'S OPERATION INEFFECTIVE.

3. Insert the pipe into the wall.The air duct must protrude by the distance indicated below:
4. Attach the mounting plate by following the diagram on page 12.
Prepare the four mounting holes and secure the mounting plate onto the part with four 4x40 screws,
and four raw-plugs 6x40 (included).
Align the air duct with respect to the mounting plate; now ll in the spaces between the wall and the
duct with silicone.The air duct does not protrude from the surface of the mounting plate.

The ventilation unit is calibrated for connection to single-phase AC mains supply 230V/50 Hz with
a 12VDC transformer (supplied).To facilitate cable routing, the unit comes with a pre-wired power
cable.
CONNECTION OF THE UNIT IN SERIES
When the ventilation units are connected in series, all the connected units are controlled to the rst
unit and a common remote control.To connect the ventilation units in series, connect the output
contact of the rst unit to the outlet of the input contact of the second one.
Now connect the second unit to the third unit in the same way; up to 10 ventilation units can be
connected in series.
Unplug the power cable while connecting the second, third, etc. units.
CONNECTING SEVERAL UNITS IN SERIES (REAR VIEW)
CONNECTING TO THE MAINS
DISCONNECT THE VENTILATION UNIT FROM THE POWER SUPPLY BEFORE ANY
ELECTRICAL INSTALLATION OPERATION. CONNECT THE VENTILATION UNIT TO AN
OUTLET PROPERLY INSTALLED WITH TERMINAL GROUND. DO NOT MAKE ANY CHANGE
TO THE INTERNAL CONNECTIONS: IT WOULD CAUSE THE LOSS OF WARRANTY
