User’s Manual

The GTV-type warm air blowers apart from the checking of suspension and cleaning of cover, lamellas and circulating fan do not need
extra maintenances but to be able to preserve the long lifetime of appliance it is recommended to have yearly supervision done with a
qualified service or expert.
Maintenance supervisions by the costumer: (recommended half a yearly)
•
supervision of circulating fan, if needed clean it (by high pressure air),
•
supervision of outblowing apertures (lamellas)
•
supervision of suspension points/surfaces by survey
WARNING! Before every maintenance the appliance must be detached from the electrical supply
by switching off the main-switch and disconnecting the connection plug located on the back side
of appliance!
ATTENTION! In case operational circumstances of appliance (atmosphere is contaminated with cor-
rosive substances,dirt) need it, then supervision and cleaning may have done more often! The main
reason of this that dirt placed on the fan may damage efficiency of appliance!
