1.0 APPLICATION
Smoke extract roof fans are designed for use in powered smoke and heat exhaust
ventilating systems in the event of fire, and ventilating in normal conditions. Ventilated areas
and emergency exits contribute to easier evacuation of people and equipment in the event
of fire, and to faster and more efficient fire extinguishing; they protect the building structure
and equipment against excessive temperatures and decrease fire escalation to the
surrounding areas.
•Fire resistance of fans: 400C, 120 min;
•installation on roofs over heated buildings;
•horizontal outlet (DVG-H) or vertical outlet (DVG-V);
•EC-motor outside air stream;
•daily ventilation of medium with temperature from -20 up to 120°C, supposing
continuously operation, up to 80°C in standstill;
•the fans DVG must not be mounted in explosion hazardous zones;
•0-10V speed control input;
•Modbus controllable;
•Fire mode to disable motor and controller protection in case of fire.
Not intended or unprofessional use can be dangerous for l
ife of user or
third person. It can lead to damage of the fan. The risk for this carries the
operator alone.

4.4 Instructions for installation
Air ducting system
The suction side of the fan is provided with a connection for flange-type mounting of the air
duct (6 resp. 8 bolts M8 on the base plate). It is recommended to mount fire proof flexible
connections between fan and duct to avoid tension or deformation of the fan base. Flexible
connection should meet temperature/duration class as well as the under pressure at
operation of the fan. In each case smooth rotation of impeller must be insured.
Any risk of unintended start
-
up of the fan and any risk of touching the
impeller during above mentioned works has to be excluded (switch off the
fan and exclude possibility of unintended start-up).
Connection of the fan to the mains
Electrical connection has to comply with valid local regulations and must be
accomplished only by a qualified electrician. In case of unprofessional
connection guarantee will not be valid. The risk for this carries the operator
alone. Observe attached detailed instructions of motor and controller
supplier – since EC motor built-in, there are warnings for remaining voltage
after supply switched off. Type of permitted RCD protective devices observe
local regulations.
Power supply to motor has to be executed in the service switch placed on the fan. Electric
motor is pre-wired with controller. Control cables should be led through the black tube to
controller. To get to controller dismount the upper cover of the fan.
For control possibilities please see attached instructions of motor and controller supplier.
