Failure Cause Explanation / corrective actions
Unit is not operating
No supply voltages
Check if the plug is connected to the plug
socket
Two-pole protection device is off or a cur-
rent leakage relay is active (if installed by the
installer)
Switch on only if the unit condition has been
evaluated by a qualified electrician. If the sys-
tem failed, the failure MUST BE rectified prior
to switching it on.
Unit door is not properly closed
Visually inspect whether the door properly
presses the end switch
Air supply heater or preheater is not operating
or malfunctioning (if installed)
Too low air flow in air ducts activates automatic
protection
Check if air filters are not clogged
Check if fans are rotating
Manual protection is activated
Possible heater or unit failure. MUST address
the servicing staff for failure detection and its
elimination.
Too low air flow at rated fan speed Clogged supply and/or extract air filter(s) Filter replacement needed
