WALL-INSTALLED, REVERSIBLE-FLOW VENTILATION UNIT
WITH HEAT RECOVERY AND REMOTE CONTROL
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".
USE
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 inowing 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 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.
MAIN TECHNICAL PARAMETERS
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 dierent to the one
described in this manual

OPERATION OF THE PICO HP2
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 lters are designed to purify the intake air and prevent the entry of objects foreign to the exchanger
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
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.
1. To mount the ventilation unit, prepare a round throughhole 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.
ø 100 - 125-150 mm
WARNING!
DO NOT INSTALL THE UNIT ABOVE DELICATE FURNITURE OR PICTURES/PAINTINGS.
DO NOT PLACE THE DEVICE ABOVE OR NEAR THERMOSTATS .

3. Insert the pipe into the wall. The air duct must protrude by the distance indicated below:
5 mm
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.
