TECHNICAL MAINTENANCE
The unit must undergo technical maintenance 3 or 4 times a year. The technical maintenance includes general cleaning of the unit and
the following operations:
1. Filter service (3-4 times a year).
Contaminated filters increase air resistance thus impairing supply air delivery into the premises. The filters should be cleaned as they get
dirty, but at least 3-4 times a year. Use a vacuum cleaner to remove the contamination or use a new filter. New filters can be purchased from
your seller.
To remove the filters (Fig. 14):
• Step 1. Undo the clips.
• Step 2. Remove the service panel.
• Step 3. Turn the retainers and remove the filters.
2. Heat exchanger inspection (once a year).
Even regular technical maintenance may not completely prevent dirt accumulation on the heat exchanger assemblies. Subject the heat
exchangers to regular cleaning to ensure high heat exchange efficiency. To clean the heat exchangers remove those from the unit and blow
with compressed air. Wet cleaning is prohibited.
To remove the heat exchangers (Fig. 14):
• Step 1. Undo the clips.
• Step 2. Remove the service panel.
• Step 4. Turn the retainers and remove the heat exchangers.
The filter and heat exchanger installation is in the reverse order of the removal.
