5. DESIGN AND OPERATING PRINCIPLE
5.1. Design ______________________________________________________________________
1 - Fan base
2 - Cooling duct
3 – External housing
4 - Motor housing
5 - Inlet port
6 - Motor base
7 - Radial rotor
8 - Electric box / service switch [option]
9 - Electric motor

6/15
The mcr Pasat roof smoke exhaust fan comprises an electrical motor with the insulation class F, a radial
rotor and an external housing assembly.
The insulated housing encloses the electric motor, on the shaft neck of which the steel rotor is installed.
The air intake to the rotor is guided by the inlet port.
The rotor is a single-sided suction rotor with swept-back blades. The rotor also features blades which
generate vacuum in the motor chamber. This sucks ambient air through the cooling duct.
The fan design facilitates draining of water out of the casing. The water to be drained may originate from
ingress of rain, melting snow or condensed water vapour from the sucked in air.
5.2. Function ______________________________________________________________________
The single-functional fans do not run in standby. When 3-phase voltage is present on the electric box
terminals, the fan is started and running.
The two-functional fans run at low speed (RPM) to handle general ventilation under normal conditions.
When the fan receives an alarm signal, it automatically starts running with the second speed, which is
higher than the first one.

with the roof surface, and install the required roof flashing. Place the smoke exhaust fan on the roof fan
base with a gasket between the roof base and the smoke exhaust fan bottom. The equipment is
fastened with 4 bolts at the fan bottom corners.
Connecting the smoke exhaust fan to the (smoke exhaust) ventilation system:
Use type KD flexible joints, which need to be fastened to the smoke exhaust fan to reduce the vibration
transmission to the ducting.
This assembly is installed by sealing the joint interfaces [with high-temperature silicone] and tightening
the two parts with the bolts sized according to the fan size. The ventilation duct must not exert loads on
the smoke exhaust fan or other components of the assembly. The ventilation duct must be supported by
independent bearing slings. Secure the smoke exhaust fan suction intake with type SO safety mesh.
When installing the smoke exhaust fan, secure the installation site and all involved structures, and
prepare passage and access ways for all personnel not involved in the installation. The smoke exhaust
fan must be assured to enable inspection and servicing.

7.3. Electrical connections_____________________________________________________
Having properly located, placed and fastened the smoke exhaust fan, connect the equipment to the
relevant electrical system wiring. Lead the wiring through the gland and into the electric box on the fan
casing; then connect the wiring to the terminals according to the diagram shown in the box.
Each fan motor must be connected to the electrical power system over a safety switch. The safety level
must be present according to the nominal current draw of the fan motor. The protective earth shall be
made according to relevant electrical engineering standards.
Once the smoke exhaust fan has been commissioned as a part of the system, measure the current draw
and verify that it meets the motor rating plate data. The smoke exhaust fan current draw in steady
operation must not exceed 1.15 times the current ratings.
The electrical power supply from the control cabinet to the fan power junction box must guarantee
uninterrupted operation in the case of a fire. This can be achieved with high temperature resistant wiring
or with protective tubing and proper safe routing of the electrical power system. No external
service/maintenance switches are to used, which is to prevent inadvertent shutdown of the smoke
exhaust fan (with the sole exception of the fan-dedicated service switch with remote indication of current
circuit switching). The smoke exhaust fan control cabinets must be powered directly from mail
switchboards with guaranteed uninterrupted power supply, even if the entire building is cut off from the
power grid. If a main fireman's switch is installed to isolate power from the entire building, the smoke
exhaust fan power supply must be independent from that solution and assure normal operation in the
case of a fire.
Electrical wiring connections must only be made by electricians with valid licenses.
Caution: Make the electrical connections and commission the motor according to the diagrams
below or the electrical diagram on the terminal box cover.
