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.

MAINTENANCE
UNPLUG THE UNIT FROM THE MAINS BEFORE STARTING MAINTENANCE.
Maintenance of the ventilation unit means regular cleaning of its surfaces from dust and clean, and
the replacement of its lters.
1. Fan maintenance (once a year).
Pull on the ventilation unit to remove.
Clean the impeller blades. To dust,
use a soft brush, cloth or vacuum cleaner.
Do not use water, abrasive cleaners, solvents or sharp
objects. The impeller blades must be cleaned
once a year.
25
2. Regenerator and lter maintenance (every 1,500
hours).
Remove the air-ow rectier.
Remove the lter in front of the regenerator.
Pull the regenerator cord to remove the air duct from
the regenerator.
Be careful when removing the regenerator, to avoid
damage. Remove the regenerator rst, then the lter.
Clean the lter when it gets dirty (every 1,500 hours).
After about 1,500 hours of operation, the unit emits a
red light signal as a reminder of the need to replace or
clean the lter. The signal continues until maintenance
is completed.
Clean the lters, dry them and insert the dry lters into
the duct.
Aspiration is permitted.
The duration of the lter is approximately three years.
Contact the seller for replacement lters.
Even technical maintenance cannot completely prevent
the accumulation of dirt on the regenerator unit.
Have the regenerator cleaned regularly to ensure high
heat-transfer eciency.
Clean the regenerator with a vacuum cleaner at least
once a year.
To reset the operating-time counter, insert the lters
and regenerator into the ventilation unit, then hold the
ON/OFF button pressed for 10 secs. until you hear a
long tone; then release.
3. Outdoor-grill maintenance (once a year).
The external ventilation grid can become clogged with leaves
or other objects that impede the smooth operation of the unit.
Check the ventilation grid twice a year, and clean it as often as
necessary.
To clean the ventilation grid, remove and clean the ventilation
cap and air duct.
26

the integrity of, the connections.
For handling, only use suitable lifting equipment to prevent damage to the unit (dropping or excessive
swing). Follow the applicable regulations regarding transport, according to the type of load.
The units can be transported by any means as long as adequate protection is provided against weather
and mechanical damage. Avoid bumps and collisions during transport and handling operations.
