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.

4.2 Safety instructions for installation, commissioning, maintenance and controlling

Installation and electrical connection must be accomplished only by

authorized technical personnel and in agreement with the valid regulations.

Any hazard of unintended touching the impeller (risk of injury!) has to be

prevented (with a duct long enough or a protective guard)!

Commissioning is allowed only after installation into the ventilation system

or after installation of protective guard (EN 13857). After installation impeller

must not be accessible anymore.

During installation, commissioning, maintenance and controlling,

unauthorized personal should not have access to the fan and installation

place.

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).

Before removing the casing cover, protective guard on the pressure side or

an eventual protective guard on the suction side make sure the fan is

separated from the mains supply.

Common rules for safety work have to be strictly observed.

4.3 Installation of the fan

•Fans type DVG should be installed outside fire zones (on roofs over heated buildings);

•Fans DVG must not be mounted in explosion hazardous zones;

•Before installation check the carrying capacity and stability of the roof;

•Fans must be installed upright in a vertical position (shaft vertical) and raised above the roof

surface on a base with minimum height of 250 mm (respectively according to expected snow

height);

•The fan shall be fixed to the base with 4 screws on the corners;

•The fan housing should not be deformed during mounting;

•Check, if impeller rotating smoothly;

•Access to the fan for maintenance must be assured.

- 5 -

At installation the dimensions of the fan and possible extension of parts by

the temperature rise has to be considered (provide flexible connection of

appropriate temperature/time class)!

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.
