Always follow the markings and directions of airflows that are marked on the stickers on the outer casing of the unit.
The unit must be connected to the piping via flexible sleeves to prevent the transmission of vibrations to the air distribution systems. The
flexible sleeves must be bridged by a flexible conductive connection for the discharge of static electricity from the device. If the elastic cuffs
are secured with spacers against damage during transport and storage, these can be removed only after the attachment of both flanges, on
the one hand to the unit and on the other to the air distribution systems.

5.2.3 CONNECTION OF ELECTRIC HEATER

The unit equipped with an electric DI heater is connected to the relevant control system and further to the electrical network. The general safety
regulations for the assembly and installation of electrical equipment apply to this equipment. On the front of the unit there is a cover with a release
button for the non-automatic thermal fuse. The non-automatic thermal fuse reacts in the event of overheating of the heater's heating block
(temperature above +120 °C). The electric heater is also equipped with an operating thermostat with automatic reset (set temperature is +60 °C,
when it is exceeded, the operating thermostat opens and switches off the heater, after cooling below +60 °C the heater automatically switches on
again).
