UNIT DESIGN AND OPERATING PRINCIPLE
The fan casing is made of aluzinc. For easy installation and operation, the top cover of the fan is secured with a special lock. The casing is heat- and sound-insulated with a 50 mm layer of non-flammable mineral wool. To ensure better noise absorption, the inner surface of the insulation is made of a perforated metal sheet. The round connecting spigots are rubber sealed.
The fan is equipped with an asynchronous motor with an external rotor and an impeller with backward curved blades. The motor with ball bearings with specially selected grease ensures low-noise, maintenance-free operation of the fan. The fan with a three-phase motor has an integrated overheating protection with an automatic restart.
Duct fans are intended for mounting to round air ducts. The fans are installed
between the air ducts. In case the fan is mounted on flexible joints, attach
the fan to a structural unit by means of supports, suspension links or
brackets (purchased separately). The fan may
be installed in any position in consideration of the air flow direction (as
indicated by the arrow on the fan casing).
INSTALLATION AND CONNECTION
WHILE INSTALLING THE UNIT ENSURE CONVENIENT ACCESS FOR SUBSEQUENT MAINTENANCE AND REPAIR.
THE UNIT MUST BE MOUNTED ON A PLANE SURFACE.
MOUNTING OF THE UNIT TO AN UNEVEN SURFACE CAN LEAD TO THE UNIT CASING
DISTORTION AND OPERATION DISTURBANCE.
-
Before installing the fan, make sure the casing has no visible damages and check the integrity of power supply wires. The fan casing
must not contain any foreign objects which can damage the impeller blades. -
Make sure the impeller rotates freely without touching the flange and the casing.
-
Mount the fan in such a way that the arrow on the fan casing matches the air flow direction in the system.
-
The casing has mounting brackets to facilitate the fan installation.
-
The fan may be installed in any position in consideration of the air flow direction (as indicated by the arrow on the fan casing).
-
To attain the best performance of the fan and to minimize turbulence-induced air pressure losses while mounting, connect the straight air duct section to the fan spigots on both sides of the fan. The minimum straight air duct length is equal to 1 air duct
diameter on the intake side and 3 air duct diameters on the exhaust side. No filters or any other similar devices are allowed to be installed in these sections.
Fan and remote terminal box installation sequence
- Before installation, lay the wires and cables necessary to connect the fan to the mains.
- Minimal distance from the fan casing to the wall is 300 mm.
- Fasteners for fan mounting are not included in the delivery set and should be ordered separately. While choosing fasteners consider the material of the mounting surface as well as the weigh of the unit, refer to the «Technical data» section. Fasteners for unit mounting should be selected by the service technician.
1. Mark the holes for mounting the fan.
2. Drill the holes according to the markings.
3. Fix the fan to the mounting surface.
4. Connect the air ducts (purchased separately) to the fan spigots.
5. Mark the holes for mounting the terminal box.
6. Drill the holes according to the markings.
7. Fix the remote terminal box to the mounting surface.
8. Unscrew the terminal box cover.
9. Make the electrical connections in compliance with the wiring diagram.
Reassemble
the terminal box in the reverse order.
CONNECTION TO POWER MAINS
POWER OFF THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT. THE UNIT MUST BE CONNECTED TO POWER SUPPLY BY A QUALIFIED ELECTRICIAN. THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE MANUFACTURER’S LABEL.
- The unit is rated for connection to 1~230 V/50(60) Hz, 3~230 V/50(60) Hz, 3~400 V/50(60) Hz power mains.
- The unit must be connected to power mains using insulated electric conductors (cables, wires). The actual wire cross section selection must be based on the maximum load current, maximum conductor temperature depending on the wire type, insulation, length and installation method.
- The external power input must be equipped with an automatic circuit breaker built into the stationary wiring to open the electric circuit in case of overload or short-circuit. The circuit breaker installation place must provide quick access for emergency shutdown of the unit. The trip current of the automatic circuit breaker must exceed the maximum current consumption of the unit (refer to the technical data table). The recommended trip current of the circuit breaker is the next current in the standard trip current row following the maximum current of the connected unit. The automatic circuit breaker is not included in the delivery set.
Connection of the fan to power mains and to additional external control units is carried out in the remote control box. The same regulator device can be used for connecting several fans simultaneously provided that their combined capacity and working current remain within the nominal parameters of the regulator. External control units are purchased separately (shown in dotted lines in the diagram).
Wiring diagrams
The fan is connected to power mains by means of the power cord with a plug
(XP) or in the remote terminal box (X1).
