MOUNTING AND SET-UP

The fan is suitable both for horizontal or vertical mounting on the floor, on the wall or on the ceiling. While installing the unit ensure convenient access for subsequent maintenance and repair. Secure the mounting bracket to the surface using screws with dowels of the appropriate size (not included in the deliverya set). Secure the fan on the bracket with clamps and bolts removed earlier. Suspend it carefully. Make sure the unit is fastened securely prior to operation. 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 that enables switching the fan on/off and smooth speed (air flow) regulation from minimum to maximum value. Rotations are controlled from the minimum (extreme right position) to the maximum (extreme left position). When rotating counter-clockwise, the rotations increase.
•  DIP switch in EXT position. The control signal is set by the R2 external control unit.

The Boost … T fan activates upon control voltage application to input terminal LT by an external switch (e.g. indoor light switch). After the control voltage is off, the fan continues to operate within the set time period adjustable from 2 to 30 min by the timer. To adjust the fan turn-on delay time, turn the control knob T counter-clockwise to decrease and clockwise to increase the turn-on delay time respectively. The Boost … Un fan is equipped with an electronic module TSC (speed controller with an electronic thermostat) for automatic speed control (air flow) depending on the air temperature. The fan switches to the maximum speed as the room air temperature exceeds the set point. As the air temperature drops 2 °C below the set point or if the initial temperature is below the set point, the fan operates with the set speed. The Boost … P fan (Fig. 23) is equipped with a speed controller that enables switching the fan on/off and smooth speed (air flow) regulation from minimum to maximum value.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

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.
