10.8 Varmeca inverter factory settings

Somer Varmeca-30 operating instructions.
10.9 Varmeca care and maintenance

Temperature variations and excessive humidity encourage the formation of condensation.
If this occurs, the condensation drain plugs at the bottom of the motor should be
removed, even in a very humid atmosphere.
 No specific servicing is required for Varmeca-30 motors, apart from regularly removing
dust from the fan grille and the cooling fins at the bottom of the unit.

Dismantling the Varmeca-30 while it is under warranty will invalidate the warranty.
