After opening the service hatch, wait for two (2) minutes before starting the maintenance
work! Although the unit’s power supply is cut when the hatch is opened, the fans still rotate
and the electrical coil in E-/EP-models is still hot for a while.
There are no user-serviceable parts behind the control panel, contact a service technician
for service and repairs of this part of the unit.
Clarify the cause of the fault before restarting the unit!
