MOUNTING AND SET-UP

• READ THE USER’S MANUAL BEFORE INSTALLING THE UNIT
• BEFORE MOUNTING, MAKE SURE THERE ARE NO VISIBLE DEFECTS ON THE UNIT, SUCH AS MECHANICAL DAMAGES, MISSING PARTS, IMPELLER JAMMING ETC.
• WHEN MOUNTING THE UNIT, IT IS NECESSARY TO PROVIDE PROTECTION AGAINST CONTACT WITH HAZARDOUS ZONES OF THE FAN BY INSTALLING AIR DUCTS OF THE NECESSARY LENGTHS AND PROTECTIVE GRILLES.
• MOUNTING MUST BE PERFORMED BY QUALIFIED SPECIALISTS ONLY, PROPERLY TRAINED AND QUALIFIED TO INSTALL AND MAINTAIN VENTILATION EQUIPMENT.

The unit is intended for mounting with round air ducts. The fan is installed between the air ducts.
The fan casing is equipped with fixing brackets for suspended mounting or for mounting on a horizontal or vertical surface.
While installing the unit ensure convenient access for subsequent maintenance and repair. 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 a service technician.
The unit can be mounted in two operation positions, which makes mounting easier. For this, dismantle the fan handle first or set it to another position.
After choosing one of two positions, securely mount the brackets to the fan.

SUSPENDED MOUNTING
Install the fan on the threaded rods (not included in the delivery set).
WARNING! When mounting the fan on threaded rods, it is necessary to provide protection of the nuts against self-loosening.

SURFACE MOUNTING
Fasten the fan to the surface using the screws with the dowels of appropriate size (not included in the delivery set). Make sure the fan is fastened securely.

Connect the air ducts of the appropriate diameter to the fan (connections must be airtight).
Air motion in the system must be in compliance with the direction of the arrow on the fan label.
To attain the best performance of the fan and to minimise turbulence-induced air pressure losses, it is recommended to connect the straight air duct section to the spigots on both sides of the unit while mounting.
Minimum recommended straight air duct section length is equal to 3 fan diameters (see the “Technical data” section).
If the air ducts are shorter than 1 m or not connected, the internal parts of the unit must be protected from ingress of foreign objects. To prevent uncontrollable access to the fans, the spigots may be covered with a protecting grille or other protecting device with mesh width not more than 12.5 mm.

ELECTRONICS OPERATION ALGORITHM

The EC motor is controlled by sending of an external control signal from 0 to 10 V to the X2 terminal block or by the R1 internal speed controller. Control method selection is carried out by means of the SW DIP switch:

• DIP switch in IN position. The control signal is set by the R1 internal speed controller, which allows turning the fan on and off, smoothly regulating the fan motor rotation speed (air flow) in the range from minimum to maximum speed.
  Rotations are controlled from the minimum (extreme right position) to the maximum (extreme left position).
  When rotating clockwise, the rotations increase.

• DIP switch in EXT position. The control signal is set by the S1 external control unit.

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.
• ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED AND WILL VOID THE WARRANTY.

The unit is designed for connection to power mains with the parameters specified in the “Technical data” section.
The connection must be made using durable, insulated and heat-resistant 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 fan connection shall be made on the terminal block mounted inside the terminal box in strict accordance with the wiring diagram and terminal designations. The external power input must be equipped with a QF automatic circuit breaker built into the stationary wiring to open the circuit in the event of overload or short- circuit. The position of the external circuit breaker must ensure free access for quick unit power-off. The automatic circuit breaker rated current must exceed the ventilator current consumption, see the Technical data section or the unit label. It is recommended to select the rated current of the circuit breaker from the standard series, following the maximum current of the connected unit. The circuit breaker is not included in the delivery set and can be ordered separately.

TECHNICAL MAINTENANCE

DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE OPERATIONS!
MAKE SURE THE UNIT IS DISCONNECTED FROM POWER MAINS BEFORE REMOVING THE PROTECTION.

• Clean the product surfaces regularly (once in 6 months) from dust and dirt.
• Disconnect the fan from power mains prior to any maintenance operations.
• Disconnect the air ducts from the fan.
• Clean the fans with a soft brush, cloth, vacuum cleaner or compressed air.
• Do not use water, aggressive solvents, or sharp objects as they may damage the impeller.
• It is forbidden to remove or change the location of the balancers on the impeller, as this can lead to increased level of vibration, noise and reduce the service life of the unit.
• During technical maintenance, make sure that there are no visible defects on the unit, the mounting brackets are securely fastened to the fan casing and the unit is securely mounted.
