ATTENTION: the fan coil is connected
to the power supply and the hydraulic
circuit. Operations performed by persons
who do not have the required technical skills can
lead to personal injury to the operator or damage
to the unit and the surrounding environment.
ROUTINE MAINTENANCE
• Routine maintenance can be performed even
by the user. It consists in a series of simple
Interventions:
Weekly external cleaning, to be done with a damp
cloth (wet with water at a maximum of 40°C) and
neutral soap; do not use any other detergents or
