Important installation caution
The heater should be installed according to local regulations and must comply with
EN60335-2-40.
A thermal fuse should be installed on the heater so that there is no danger of damage to
the heater and no safety risk when the fan is stopped or when the PCB is malfunctioning.
The electric heater must be installed on a safe location in the discharge duct, so that there
is no danger for damage to the unit.
Maximum temperature in the discharge duct may not exceed 90°C. Select the proper
safety device or thermal protector accordingly.
Temperature on the unit casing may not exceed 70°C.
