6. IDENTIFICATION
MARKING_______________________________________________________
Example of smoke exhaust fan identification:
mcr Monsun - 50 / 4 - 1.5 - 5 / F400
7. INSTALLATION_____________________________________________
The mcr Monsun smoke exhaust axial fan is designed for vertical and horizontal installation. The
equipment can be installed indoors or outdoors.
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.
7.2. Location and assembly_______________________________________________________
The mcr Monsun smoke exhaust fan can be installed horizontally or vertically. Prior to installation, verify
the load bearing capacity of the roof, floor, wall or ceiling where the equipment is to be located.
If the smoke exhaust fan is to be installed vertically on a roof, prepare and secure an opening in the roof
slope at a diameter that fits the equipment. Set a special roof fan base over and aligned with the opening,
and suitable for the roof type, the fan weight and the fan diameter. Level out and anchor the roof fan base
to the roof slope. Put the fan on the roof fan base. Fasten both the equipment to the base with bolts.
Secure the fan exhaust with a roof exhaust vent assembly to prevent rain water and snow from entering
the building through the ducting.
When installing the smoke exhaust fan vertically on a baseplate, put the equipment on type PP vertical
support. It is recommended to bolt vibration dampers to the support in order to reduce the vibration from
the fan operation.
When installing the smoke exhaust fan horizontally, fasten type SW bottom feet to the fan housing flange
with bolts. Set the finished assembly on previously prepared vibration dampers, which have been
previously anchored to the substrate or a framework. The anchor and bolt diameter and length must match
the equipment size.
When installing the smoke exhaust fan below a ceiling, do this on a suitable support structure. Install the
vibration dampers and bottom feet on the support structure, then place the smoke exhaust fan there. The
anchor and bolt diameter and length must match the equipment size.
Connecting the smoke exhaust fan to the (smoke exhaust) ventilation system:
Connect the ventilation duct to the smoke exhaust fan via type PK counterflanges. 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. If the suction and forcing is free-flow, secure the smoke exhaust
fan intake and exhaust with type SO safety mesh. If the smoke exhaust fan is operated within a ventilation
