BRIEF DESCRIPTION

The product is an axial fan for exhaust ventilation of small and medium-sized premises heated in winter. The design of the fan
may include a back valve that prevents air from flowing into the room when the fan is off. The fan is designed for connection
to ø100 mm air ducts.

OPERATION GUIDELINES

The fan is rated for connection to 220-240 V/50 Hz single-phase AC power mains, depending on the model type. For more
detailed information, see the casing sticker. Ingress protection rating against access to hazardous parts and water ingress is IP44.
The manufacturer’s recommended operating temperature range is from +1 °C to + 40 °C.
The unit is rated as a Class II (220-240 V/ 50 Hz) electric appliance.

MOUNTING

The fan can be mounted to the ceiling or onto a wall with air extraction into a ventilation shaft or a matching diameter round air duct (Fig. 2). The fan installation steps are given on Fig. 3-11. Electric connection diagrams are given on Fig. 12-13.

ELECTRONIC SYSTEM OPERATION ALGORITHM

The CT model fans equipped with a timer are activated by control voltage application to input terminal S by an external switch (e.g. indoor light switch). Upon control voltage removal the fan continues to operate for the period of time set by the timer within the range from 2 to 30 minutes.

The CH model fans equipped with a timer and a humidity sensor are activated by control voltage application to input terminal S or on exceeding the pre-set humidity level H adjustable within the ~60 % to ~90 % range. Upon control voltage removal or a decrease of humidity level H the fan continues to operate for the period of time set by the timer within the range from 2 to 30 minutes.

— To adjust the fan activation delay time, turn the Ton potentiometer knob clockwise (+) or counter-clockwise (-) which sets the activation delay time within the range from 0 to 2 minutes.

— To adjust the fan deactivation delay time, turn the Toff potentiometer knob clockwise (+) or counter-clockwise (-) which sets the activation delay time within the range from 2 to 30 minutes.

— To adjust the humidity sensor threshold value turn the H potentiometer knob clockwise (+) or counter-clockwise (-) which sets the threshold value within the range from 60 % to 90 %.

THE TIMER CIRCUIT IS LIVE.
MAKE SURE THE FAN IS DISCONNECTED FROM POWER SUPPLY.

The fan is supplied with a special plastic screwdriver. Use the
screwdriver to adjust the fan activation or deactivation delay
time or the humidity sensor threshold value.

DO NOT USE A METAL SCREWDRIVER, KNIFE, ETC. FOR ADJUSTMENT
OPERATIONS NOT TO DAMAGE THE CIRCUIT BOARD.

MAINTENANCE

To clean the unit from any dust and dirt which may accumulate on the surfaces (Fig. 14-17), use a soft cloth and a brush soaked in a mild detergent solution. Avoid spilling liquid on the electrical components. Wipe the cleaned surfaces dry.
