aldes DFE Série Manuel D'installation Et De Maintenance page 30

Protect the heat exchanger by regularly cleaning or replacing the filters.
To protect from frosting, the DFE control is as standard delivered with an inbuilt heat exchanger antifreeze system
(by unbalancing the in and out airflows).
The DFE units are specified not to exceed a frontal air speed on the heat exchanger of 2,5m/s.
Fan maintenance
Before proceeding to maintenance, first stop the fans using the soft stop feature and the only then proceed to the
shutdown of the power supply. Verify the state of the fans. If they need to be cleaned use dry or moist cloths with a
degreaser. Be careful not to alter the balancing of the fans when doing this. Do not remove the clips of balancing).
Filters
DFE units are delivered in standard with G4 filters. F7 filter can be delivered in option for the air 'in' flow. Filters are
the protectors of the heat exchanger, but also of the quality of the air you breathe. Check regularly (once a month)
the state of the filters. Vacuum the filters if necessary, and replace them when they are too dirty. Clogged filters can
create the following failures:
- Insufficient ventilation
- Excessive increase of the rotation speed of the fan creating excessive noise and power consumption
- A damaged filter allows 'dirty' air to enter the heat exchanger which will eventually clog the heat exchanger

Installation control datasheet (see appendix)
When the installation is completed and running, we strongly advise that the installer fills in the installation datasheet
recapitulating all the data useful for maintenance of the installation. Please keep a copy of this datasheet close by as
it may come handy for many reasons:
•
make a clear communication in case of discussion with the manufacturer
•
information if you need to change parameters when necessary,
•
This document can become an important factor in case of guarantee issues.
Guarantee
The guarantee of the manufacturer begins at the date of invoicing of ALDES to the installer. The guarantee is of 2
years, except on the mobile parts where it is of 1 year.
The guarantee is limited to the replacement of the defective parts, and does not include labor and traveling
expenses. The guarantee becomes void if:
•
The installation is not accomplished according to the prescriptions described in this above.
•
Repairs were carried out by unqualified staff.
•
The start-up control datasheet (see appendix) is not filled in properly and not made available when claiming
Conformity
CE: Under formal condition that the final product integration is made in conformity with the applicable standards.
