4. MAINTENANCE & WARRANTY
• The CAR3 needs no maintenance when used in normal conditions. The addition of antimicrobial and
anti-static additives in the material increases the longevity and reliability of the CAR3. There is no risk
of dust deposit or obstruction because the CAR3 has no airways subject to clogging. If the intended
application includes air heavily loaded with dust or grease, access to the CAR3 should be possible
through the terminal device or with an access panel or door.
• ALDES Ventilation Corporation warrants the CAR3 to be free from manufacturing defects and
guarantees the performance within specified limits for a period of seven (7) years when installed in
normal environmental air systems for general residential and commercial heating, ventilating and air
conditioning. This warranty does not include installation in industrial applications or caustic, noxious
or otherwise hazardous airhandling equipment. This warranty is limited to replacement of the product
only and does not extend to consequential claims.
