General information on cleaning procedures
Read the safety instructions at the beginning of this manual and page. 53
You should consult with your supplier of chemical products to choose the most suitable for clean-
ing the unit components.
For the cleaning method refer to the instructions of the detergent manufacturer and carefully
read the safety data sheet (SDS).
As general guidelines, refer to the following rules:
• Always use personal protection (safety shoes, safety glasses, gloves, etc.).
• Use mild products (pH between 8 and 9) for washing and disinfecting, in normal concentrations. De-
tergents must not be toxic, corrosive, flammable or abrasive.
• Use a soft cloth or bristle brushes that do not damage the stainless steel surfaces.
• If you use water jets, the pressure should be less than 1.5 bar and the temperature must not exceed 80°C.
• For cleaning components like motors, damper motors, bearings, pitot tubes, filters and electronic sen-
sors (if applicable), do not spray water directly on them.
• After cleaning make sure that you have not damaged the electrical parts and the seals.
• Cleaning operations should not involve the lubricated parts, like rotation shafts, because this could
affect their good operation and create problems with durability.
• For the cleaning of finned components or dampers use an industrial vacuum cleaner and/or a com-
pressor. Attention, the compressed air flow must run opposite to the direction of the airflow through
the unit and parallel to the fins.
Cleaning filters
The machine must NOT be running when the filters are removed to avoid drawing in outside air
that might be contaminated.
The filters must be cleaned often and carefully to prevent dust and microbial build-up. Usually, compact
filters can be cleaned
two or three times
(replacement is anyway recommended in preference to wash-
ing) before they are replaced. As a general rule, replacement is required after 500-2000 hours of operation
(it varies depending on the type of filter, refer to the directions of the Manufacturer), but may need to be
replaced much sooner if required.
Compact filters
can be cleaned using a vacuum cleaner or by blowing with compressed air or hot water
(not under pressure).
Pocket filters
cannot be cleaned and must be changed after their life cycle.
Cleaning lamellar components
Remove the dust and fibres with a soft bristle brush or a vacuum cleaner.
Be careful when cleaning with compressed air because the exchanger package can be damaged.
CLEANING with pressure jets is allowed if the maximum water pressure is 3 bar and a flat nozzle
is used (40° - WEG 40/04 type).
Oils, solvents, etc. can be removed with water or hot grease solvents, by washing or immersion.
Periodically clean the condensate drain tray and fill the drain siphon with water.
