BRIEF DESCRIPTION
The product described herein is a mixed-flow inline fan for supply or exhaust ventilation of premises heated
during winter time.
The fan is designed for connection to ø 4’’, 5’’, 6’’, 8’, 10’’ air ducts.
The fan is equipped with an energy-efficient and high-performance electronically commutated motor (EC
motor) and with a built-in speed controller.
An external control unit can be connected to the fan (purchased separately).
The fan design is constantly being improved, thus some models may be slightly different from those described
in this manual.
OPERATION GUIDELINES
The fan is rated for connection to single-phase AC 120 V/60 Hz power mains.
The fan is rated for continuous operation.
Air motion direction in the system must match the pointer on the fan casing.
Hazardous parts access and water ingress protection rating is IPX4.
The fan is rated for operation at the ambient temperature ranging from +34 °F up to +104 °F.
Transported air temperature must not exceed +104 °F. Temperature up to +140 °F is allowed for a short time
(up to 15 minutes).
The ventilator is rated as a class II electric appliance.

INSTALLATION
The fan is suitable both for horizontal or vertical mounting on the floor, on the wall or on the ceiling (Fig. 1).
While mounting the fan provide extra protection against water ingress, such as:
1. For the top mounting: install an outer protecting hood above (Fig. 2).
2. For any mounting position: connect an air duct on both sides of the fan (Fig. 2).
The mounting sequence is shown in Fig. 3-8.

OPERATION ALGORITHM
The 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 to turn the
fan on and off, smoothly adjust the speed of the fan motor (air flow) in the range from minimum to maximum
speed.
Rotations are controlled from minimum (extreme left position) to maximum (extreme right position). When
rotating clockwise, the rotations increase.
- DIP switch in EXT position. The control signal is set by the S1 external control unit.
MAINTENANCE
Clean the product surfaces regularly (once in 6 months) from dust and dirt (Fig. 16-19). Disconnect the fan from
power mains prior to any maintenance operations. To clean the fan, use a soft cloth or a brush wetted in a mild
detergent solution. Avoid water ingress to electrical components.
Wipe the unit surfaces dry after cleaning.
