WARNING
PROHIBITION
USE OF THE RECOVERY UNIT
The recovery unit was designed to ensure the air exchange in apartments, holiday farms, hotels,
bars and, in general, domestic and public places.
The recovery unit is tted with a ceramic exchanger which allows the air recirculation thanks to the

and 500 mm (optional tube L=1,500 mm), for the “Pico Reco 100”, the minimum thickness is 370 mm.
The recovery unit was tested for continuous operation connected always to be mains supply.
The transported air must not contain ammable or explosive mixtures, chemical substance
vapours, large dust particles, soot and oil particles, dangerous substances, brous
materials, pathogenic agents or other harmful substances.
THE RECOVERY UNIT WAS NOT DESIGNED FOR USE BY CHILDREN, PERSONS
WITH PHYSICAL OR MENTAL DISABILITIES, PERSONS WITH SENSORY
DISABILITIES, OR PERSONS WITHOUT ADEQUATE QUALIFICATIONS.
THE INSTALLATION AND CONNECTION OPERATIONS CAN BE PERFORMED
ONLY BY QUALIFIED PERSONNEL AFTER FOLLOWING THE ADEQUATE

OPERATION OF RECOVERY UNITS
MODEL “PICO HP2” AND MODEL “PICO RECO 100”
The recovery unit consists of a xed length circular air duct, ventilation unit and external grille.
The two motors, two lters and the exchanger are inside the duct.
The lters are protected in order to purify the supply air and to prevent foreign objects
entering the exchanger and the fans.
The recovery unit generates a visual alarm (red LED indicator) as a reminder to clean or replace
the lter every 1,500 operating hours.
The ceramic exchanger (for the “PICO HP2” models) uses the thermal energy of the intake air in
order to heat the intake air ow.
For the “PICO RECO 100” model, the ll media is made of polyester.
The exchanger is tted with a draw cord on the inside to make it easier to extract (for the “PICO
HP2” models) and special clip for the “PICO RECO 100” model.
The ventilation unit must be installed on the inside part of the wall.
The external grille must be installed on the external part of the wall in order to prevent
water and other objects from entering the recovery unit.

WARNINGS FOR THE ASSEMBLY
WARNING!
THE RECOVERY UNIT SHOULD NOT BE INSTALLED IN
PLACES WHERE THE AIR DUCT MIGHT BE BLOCKED BY
BLINDS AND SHUTTERS, ETC. IN ORDER TO PREVENT
THE ACCUMULATION OR DEPOSIT OF DUST. MOREOVER,
THE BLINDS MIGHT OBSTRUCT THE NORMAL AIR FLOW IN
THE ROOM, MAKING THE OPERATION OF THE RECOVERY
UNIT INEFFICIENT.
WARNING!
DO NOT PLACE THE DEVICE ABOVE DELICATE FURNITURE
OR PICTURES. DO NOT PLACE THE DEVICE ABOVE OR
NEAR ROOM THERMOSTATS.
To mount the recovery unit, make a circular hole through the wall that is big enough to allow
insertion of the tube supplied for the various recovery unit models.
NOTE:
for diameters of the external tube, please refer to page 4 for the recovery units mod. “PICO HP2”
and page 5 for the recovery unit mod. “PICO RECO 100”

CONNECTION TO THE MAINS
BEFORE PERFORMING ANY ELECTRICAL ASSEMBLY OPERATION, DISCONNECT
THE RECOVERY UNIT FROM THE MAINS. CONNECT THE RECOVERY UNIT TO
A SOCKET INSTALLED CORRECTLY WITH THE GROUNDING TERMINAL. IT IS
FORBIDDEN TO PERFORM ANY MODIFICATION TO THE INTERNAL CONNECTIONS
WHICH MIGHT CAUSE THE WARRANTY TO BE VOIDED
The recovery unit is calibrated for connection to the AC mono phase mains supply 230 V / 50 Hz
by means of a 12 Vdc transformer (provided). To make the connection easier, the recovery unit
is tted with a 500 mm long pre-wired power cord.
In order to power the recovery unit, insert the phone type connector in the specic socket
marked with the word IN. (see pic. 6)
CONNECTION OF RECOVERY UNITS IN SERIES
When the recovery units are connected in series, all the connected recovery units are controlled
by the rst recovery unit and a single remote control. In order to connect the recovery units in
series, connect the exit contact press of the rst recovery unit (identied with the OUT word) to
the entry contact press of the second recovery unit (identied with the IN word)

MAINTENANCE
DISCONNECT THE FAN FROM THE MAINS SUPPLY BEFORE CARRYING
OUT MAINTENANCE.
Maintenance of the fan means regularly cleaning the surfaces of the fan from dust and cleaning
or replacing the lters.
1. Maintenance of fans (once a year).
Remove the ventilator unit by pressing
simultaneously on the two locks.
Clean the blades of the impeller. In order to remove the dust,
use a soft brush, a cloth or the vacuum cleaner.
Do not use water, abrasive detergents, solvents, sharp
objects. The blades of the impeller must be cleaned once
a year.
SPECIAL LOCK
39
2. Maintenance of the regenerator and of the lter
(every 1,500 hours).
Remove the lter in front of the regenerator.
Pull the cord of the regenerator in order to remove
the regenerator from the air duct.
Take care when extracting the regenerator to avoid
damaging it. Remove the lter behind the regenerator.
Clean the lter when it is dirty (every 1,500 hours).
When the 1,500 hour operation period ends, a red
indicator LED lights up on the fan as a reminder of
the need to replace or clean the lter. The signal is
repeated until the maintenance has been completed.
Clean the lters, let them dry and insert the dried
lters in the duct.
Extraction is allowed.
The life span of the lters is of about 3 years.
For spare lters, contact the seller.
Even regular maintenance cannot fully prevent the
accumulation of dirt on the regenerator group.
Clean the regenerator regularly to ensure high
efciency heat exchange.
Clean the regenerator with a vacuum cleaner at least
once a year.
In order to reset the operation time meter, insert the
lters and the regenerator in the fan, then keep the
ON/OFF button pressed for 5 sec. and when you
hear a prolonged sound, release it.
3. Maintenance of the external grille (once a year).
The external ventilation grille can get blocked by leaves or
other objects which prevent the unit from working properly.
Check the ventilation grille twice a year and clean it whenever
necessary.
To clean the ventilation grille, remove it, then clean the air
duct.

TRANSPORTATION AND STORAGE
The recovery unit must be put in the original packaging in a ventilated area at a temperature
ranging between +10°C and +40°C.
The air must not contain potentially aggressive vapours or chemical mixtures that might cause
corrosion or compromise the integrity of the connections.
For handling, use only adequate lifting equipment, in order to prevent damage to the fan following
falls or excessive shaking. Follow the applicable regulations for transportation according to the
type of load.
The recovery unit can be transported with any means, provided that adequate protection against
atmospheric agents and mechanical damages is ensured. Avoid jolts and collisions during
transportation and handling operations.

DISPOSAL OF THE APPLIANCE
At the end of its useful life, the product must not be disposed of with household waste. It can be
deposited at a dedicated recycling centre run by local councils, or at retailers who
provide such a service. To highlight the requirement to dispose of household electrical items
separately, there is a crossed-out waste paper basket symbol on the product.
