Maintenance Procedure - Mitsubishi Daiya SAF150E6 Anwenderhandbuch

Maintenance Procedure

When running the air-to-air heat exchange unit over the long term, dust and dirt accumulated
in filters may cause ventilation air volume to decrease and, as a result, effciency of ventilation
may decrease, or abnormal sounds or abnormal vibration may be noticed. Clean off dust
and dirt attached to filters and heat exchange elements periodically according to the level of
contamination.
