Mounting and Set-up

Important: Read the user's manual before installing the unit. Ensure there are no visible defects (mechanical damage, missing parts, impeller jamming) before mounting. Provide protection against contact with hazardous zones by installing air ducts and protective grilles.

Mounting must be performed by qualified specialists trained in installation and maintenance of ventilation equipment.

The fan can be mounted horizontally or vertically on the floor, wall, or ceiling. Ensure convenient access for maintenance. Secure the mounting bracket to the surface using screws and dowels. Fasten the fan on the bracket with clamps and bolts. Suspend carefully and ensure secure fastening before operation.

Connect air ducts of the appropriate diameter to the fan spigots, ensuring airtight connections. Air motion must comply with the direction of the arrow on the fan label.

For optimal performance and to minimize turbulence-induced pressure losses, it is recommended to connect straight air duct sections of at least 3 fan diameters (see Technical Data) to the fan spigots. If air ducts are shorter than 1m or not connected, protect the internal parts from foreign objects.

To prevent unauthorized access, spigots may be covered with a protective grille or other device with mesh width not exceeding 12.5 mm.

Diagrams illustrating mounting options are provided, showing different orientations and connections to air ducts.

Electronics Operation Algorithm

The EC motor is controlled via an external 0-10V signal to the X2 terminal block or by the R1 internal speed controller. The SW DIP switch selects the control method:

• IN: The R1 internal speed controller manages fan on/off and smooth speed (air flow) regulation from minimum to maximum. Rotation is controlled counter-clockwise for increasing speed.
• EXT: The R2 external control unit sets the control signal.

Primo ... T fan: Activates upon control voltage application to the LT input terminal (e.g., from an indoor light switch). After the control voltage is removed, the fan continues to operate for a set time period (2-30 minutes) adjustable via the timer knob (T). Turning the knob counter-clockwise decreases the delay, clockwise increases it.

Primo ... G1 fan: Equipped with an electronic module TSC (speed controller with electronic thermostat) for automatic speed control based on air temperature. The fan switches to maximum speed when room air temperature exceeds the set point. If the air temperature drops 2°C below the set point, or if the initial temperature is below the set point, the fan operates at the set speed.

Primo ... FR1 fan: Equipped with a speed controller for fan on/off and smooth speed (air flow) regulation from minimum to maximum value.

Connection to Power Mains

Important: Power off the unit before any operations. Connection must be made by a qualified electrician. Rated electrical parameters are on the manufacturer's label. Tampering with internal connections voids the warranty.

The unit is designed for connection to power mains as specified in the "Technical data" section. Use durable, insulated, and heat-resistant conductors. Wire cross-section selection must be based on maximum load current, conductor temperature, insulation, length, and installation method.

Fan connection is made via the terminal block inside the terminal box, strictly following the wiring diagram and terminal designations. The external power input must have a QF automatic circuit breaker in the stationary wiring for overload or short-circuit protection. The circuit breaker must be easily accessible for quick power-off. The breaker's rated current must exceed the ventilator's current consumption (refer to Technical data or unit label). Select the breaker's rated current from standard series, based on the maximum current of the connected unit. The circuit breaker is not included and can be ordered separately.
