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.

MAINTENANCE
DISCONNECT THE FAN FROM THE MAINS SUPPLY BEFORE CARRYING
OUT MAINTENANCE.
SPECIAL LOCK
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.

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
efciency 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.

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.
