systems is -20°C to + 40°C.
The fan may force dry air only, with a maximum particulate content of 0.3 g/m³.
This fan is not intended for forcing air with viscous pollutants that may settle
on the equipment, especially on its rotor.
This fan is not intended for forcing air with corrosive pollutants that may be
detrimental to the equipment.
The maximum actual rotor RPM must never exceed the nominal (rated) RPM
speed in operation.
Following operation in actual fire conditions, the fan will not be fit for further
use.

6. DESIGN AND OPERATING PRINCIPLE _____________________________
6.1 Design _________________________________________________________________________
The mcr Bora jet fan comprises an electrical motor with a suitable insulation class, an axial rotor, a blade
assembly, an outer casing assembly and silencers.
The motor is coupled directly to an aluminium rotor on bearings, and on the rotor the profiled blades are
installed. The angle and number of blades depend on the required thrust and capacity of the fan. The
motor bearings are high temperature resistant and maintenance free. On the inlet and outlet side the
engine is connected to silencers. The medium, which is fire gases and air with smoke, flows through the
casing, the motor, the rotor blades and the silencer.
The mcr Bora fans in O and L versions have a connection box located on the casing.
All types of fans have fasteners or assembly frames, depending on the fan size.
6.2 Function _______________________________________________________________________
The fan does not run while in standby. When 3-phase voltage is present on the terminal box terminals,
the fan is started and running.
6.3 Dimensions and technical features __________________________________________
The basic dimensions of fans as well as their technical parameters are given below.

7. INSTALLATION_____________________________________________
The mcr Bora smoke exhaust jet fan is intended for use in rooms designed for moving air and fire gases
(in the fire zone).
7.1. Pre-assembly inspection____________________________________________________
Each smoke exhaust fan is factory inspected by the manufacturer prior to packing and shipping. Upon
unpacking the delivered smoke exhaust fan, visually examine it for any damage in transport.
The motor shaft should rotate with the rotor without evident resistance or scraping.

“MERCOR” SA – The company reserves the right to modify and change the document 7/11
7.2. Location and assembly_______________________________________________________
The mcr Bora fan is designed for horizontal installation. Prior to installation of the fan, verify the load
bearing capacity of the ceiling or other structural element where the equipment is to be suspended. Use
the mounting frame (part of the fan itself) or the fasteners supplied with the fan. Using the above
mentioned element, the device is fitted to the structural elements using bolts or using hangers (not
supplied).
Fan due to his construction, does not require vibration isolation between the structural elements and the
device. In case of demanded by bulining project assembly by means of vibration insolation, the
manufacturer recommend to instal the device according to drawing 2. Other assembly may be provided,
providing that the device is safe and undisturbed, in normal operation and fire condtions. Screws,
anchors, suspensions (diameter, length) and other assembly elements must be selected for the size of
the device and the required fire resistane.
Drawing 2 Example illustrating how to install the mcr Bora with
vibration isolation elements.
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 terminal box on the fan
casing; then connect the wiring to the terminals in accordance with the diagram shown in the box. The
electrical wire with the proper fire resistance rating is installed in standard by the manufacturer between
the fan motor and the terminal box. Each fan motor must be connected to the electrical power system
through an overcurrent switch. The safety level must be set in accordance with the nominal current draw
of the fan motor. The protective earth shall be made in accordance with 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 1.1 times the rated current.
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 main
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

“MERCOR” SA – The company reserves the right to modify and change the document 8/11
exhaust fan power supply must be independent from that solution and assure normal operation in the
case of a fire.
7.4. COMMISSIONING _____________________________________________________________
Before commissioning your installed smoke exhaust fan do the following:
 Check that the smoke exhaust fan is properly and firmly fastened.
 Check all seals for tightness.
 Check that all electrical wiring is properly and firmly connected.
 Check that the phase connection sequence and PE/neutral wiring is properly connected.
 Check that the smoke exhaust fan is free of foreign objects.
 Check that all protective/safety components have been installed.
 If the checks are positive, start the fan and do a functional test.
 When starting the smoke exhaust fan, verify the motor direction of rotation against the direction
arrow on the enclosure.
8. TRANSPORT & STORAGE CONDITIONS __________________
The mcr Bora smoke exhaust fans are placed on pallets during transport and storage. Do not topple or
throw the packaging during loading and transport. The smoke exhaust fans can be handled and shipped
using any means of transport, provided that they are secured against weather. The smoke exhaust fans
must be secured against shifting while on transport vehicles. Visually inspect each piece of equipment
following transport and handling.
Store in sheltered rooms, where:
 there is no exposure to particulates, gases, corrosive vapours and other aggressive chemical
emissions detrimental to insulation parts and structural components of the fan and/or its motor;
 the maximum relative humidity is 80% at +20°C;
 the ambient temperature is between -20ºC and + 40ºC;
 no vibrations are present.
9. SAFETY MANUAL________________________________________________
Read and understand this Operating and Maintenance Manual before commissioning and servicing the
product.
The smoke exhaust fan is not hazardous when firmly attached to a ventilation system and the fan
support structure.
Make the electrical connections in accordance with the enclosed electrical wiring diagram and the
guidelines in Section 7.3. Electrical connections shall be made by personnel with relevant qualifications
which have been certified as required by current laws.
Inspect the PE wire connection of the smoke exhaust fan during the operating life.
Disconnect the smoke exhaust fan from electrical power before any inspections or checks.
CAUTION:
1. Do not clean smoke exhaust fans of deposits with pressure or steam washers.
2. Loss of seal at the fan connections or flexible ends may result in hazards due to release of the forced
medium and requires immediate replacement of leaking components.
If the equipment is malfunctioning (e.g. excessive noise, vibration and/or erratic operation is found),
disconnect the fan from electrical power supply, and call the manufacturer's technical service or an
inspection and repair contractor authorised by the manufacturer.
10. MAINTENANCE & SERVICING____________________________________
The equipment from “Mercor” SA requires periodic technical inspection and maintenance at least every
12 months throughout its operating life, i.e. during the warranty and post-warranty period. Inspection and
maintenance may only be carried out by the manufacturer or contractors authorised by “MERCOR” SA to
service its products.

“MERCOR” SA – The company reserves the right to modify and change the document 9/11
