BRIEF DESCRIPTION

The product is an axial fan for exhaust ventilation of small and medium-sized premises.
The fan is designed for connection to Ø 100 mm air ducts depending on the model.

OPERATION GUIDELINES

The fan is rated for connection to single-phase AC power mains.
Power supply parameters are stated on the unit packaging and/or the label on the unit casing.
Ingress protection rating against access to hazardous parts and water ingress is IP44.
The fan is rated for operation at ambient temperatures ranging from +1 °C to +40 °C.
The unit is rated as a Class II (220-240 V, 50 Hz/220 V, 60 Hz) electrical appliance and requires no grounding.
WARNING! Do not operate the fan outside the specified temperature range.

DESIGNATION KEY

INSTALLATION

The fan is designed for wall mounting (with motors on sliding and ball bearings) or ceiling mounting and can be used to discharge air directly outside through a round duct or through a duct system.
In case of installation through a duct system, select the duct cross section in accordance with the fan size (Fig. 1).

1. When installing the fan with direct air discharge outside through the wall, be sure to install a ventilation grille with louvre shutters or a ventilation hood on the outside to  prevent rainfall, snow, leaves, branches, etc. from entering the duct.
   To reduce the risk of condensate forming in the duct, the space between the hole in the wall and the duct must be insulated.
   Install the air duct with the minimum slope of 1…2° downwards to the outer wall side for condensate removal (Fig 2).

2. The duct system should not exceed 5 meters and have more than two bends.

3. During ceiling installation, vertical air discharge upwards is not allowed even if there is a protective outer hood on the roof.
   For ceiling mounting and air discharge to the roof, the duct system must include a condensate drain (Fig. 3).
   A condensate drain is not included in the delivery set of the fan and can be ordered separately.
   Check the fan for any visible damages of the impeller and the casing before starting installation. The casing internals must be free of any foreign objects which can damage the impeller blades.
   While mounting the unit, avoid compression of the casing! Deformation of the casing may result in the motor jam and excessive noise. Mount the fan on the wall or ceiling using four dowels with screws (included in the delivery set).
   Dowels and screws are designed for concrete and brick walls. If the walls are made of another material (drywall, wood, etc.), use the fasteners appropriate for these  materials to fasten the fan (not supplied with the fan and must be purchased separately).
   WARNING! When the fan is equipped with a non-return valve, operation of the fan without a valve is prohibited.

The fan mounting sequence is shown in Fig. 4-12.
The fan wiring diagrams are shown in Fig. 13-14.
Terminal designations on wiring diagrams:

L — line
N — neutral
S — timer control line
S1 — external switch
QF — automatic circuit breaker

WARNING! The power cable may only be laid through the hole in the casing provided by the manufacturer (Fig. 13). Laying the power cable through a manually drilled hole will not be the liability of the manufacturer and will void the warranty. The wires must be stripped of insulation by a maximum of 8 mm (Fig. 13).
After installation, pass this User’s manual to the end user for reading.

ELECTRONICS OPERATION ALGORITHM

The fan with the CT timer activates upon control voltage application to the S input terminal by the S1 external switch (e.g. indoor light switch). After the control voltage is  off, the fan continues to operate within the time set by the timer ranging from 2 to 30 minutes.
The fan with the timer and the humidity sensor CH – the fan starts after the control voltage is supplied to the input terminal S or if indoor humidity level H exceeds the set  point adjustable from ~60 % to ~90 %.
After the control voltage is off or the humidity level has decreased, the fan will keep running within the time set by the turnoff delay timer ranging from 2 to 30 minutes.

— To adjust the fan turn-on delay time, turn the control knob clockwise to increase and counter-clockwise to decrease the turn-on delay time respectively, adjustable from 0 up to 2 minutes.
— To adjust the fan turn-off delay time, turn the control knob clockwise to increase and counter-clockwise to decrease the turn-off delay time respectively, adjustable from 2 up to 30 minutes.
H — To adjust the humidity set point, turn the control knob H clockwise to increase and counter-clockwise to decrease the humidity sensor set point, adjustable from 60 % up to 90 %.
The fan delivery set includes a specially designed plastic screwdriver for fan settings adjustments.
Use it to change the turn-on and turn-off delay time and the humidity set point.

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

TECHNICAL MAINTENANCE

The fan maintenance periodicity is at least once per 6 months.
Maintenance steps:

• Disconnect the fan from power supply and make sure electricity has been turned off (Fig. 15).
• Remove the front and the decorative panels, wipe the fan with a dry cloth or a brush (Fig. 16).
• Clean the front panel under running water (Fig. 17).
• Wipe the fan surfaces dry.
• Cover the fan with the front panel.
• Connect power supply to the fan (Fig. 18).

WARNING! Do not allow water or liquid come into contact with electric components!
