works. Unqualified staff should only carry out basic tasks such as cleaning and replacement of
filters, etc.

Installation, operation and maintenance instructions, as well as the ones indicated in labels of
the unit. Do not forget to strictly follow any other safety codes.
• Use safety glasses, work gloves and any other safety accessory necessary.
• For brazing operations use a quenching cloth and have at close distance a fire extinguisher.

Before starting installation, service or maintenance, turn off the main power switch in order to
avoid electrical shock that may cause personal damages.
• When repairing the unit, use only original spare parts and install them properly in the same
position where old parts were placed.
• These units are designed to work with 100% recirculated air. The installation with 100%
outdoor air is prohibited. See application limits.
