VENTS Simple Axial Fan User's Manual

Brief Description

The VENTS Simple is an axial fan designed for exhaust ventilation in small to medium-sized premises. It is constructed from white plastic and may include a backdraft damper to prevent airflow reversal when the fan is off. The fan is compatible with air ducts of 100, 120, 125, and 150 mm diameters.

Operation Guidelines

The fan connects to single-phase AC power mains: 220-240 V/50 Hz, 220-240 V/60 Hz, or 12 V/50 Hz, depending on the specific model. Ensure the air motion direction aligns with the pointer on the fan casing. The unit has an ingress protection rating of IP34 against hazardous parts and water. It is designed for operation in ambient temperatures from +1°C to +40°C. For 220-240V models, it is rated as a Class II electrical appliance, and for 12V models, as a Class III electrical appliance.

Installation and Setup

The fan is designed for wall or ceiling mounting, exhausting air directly into a ventilation shaft or a round air duct of matching diameter.

Installation Sequence:

1. Disconnect power supply and ensure electricity is turned off.
2. Run the power cable to the vent hole.
3. Remove the fixing screw and the front panel of the fan.
4. Remove the terminal block cover.
5. Mark and drill holes for mounting the fan.
6. Install the fan and connect to power mains according to the wiring diagram.
7. Install the terminal block cover and the front panel on the fan casing.
8. Supply power voltage to the fan.

Terminal Designations:

• L: Phase
• N: Neutral (0)
• LT: Control terminal
• S: External switch
• QF: Automatic circuit breaker

CAUTION! Fans rated for 12 V power voltage must connect to 12 V power mains only.

The unit with IP34 protection rating is allowed in Zone 2 according to IEC 60364-7-701:2019.

Diagram Description (Fig. 2): Illustrates installation zones for the fan, showing a bathroom/shower area with zones 1 and 2 marked. Zone 1 is directly above the bath/shower, and Zone 2 is adjacent to it. The fan's IP34 rating is suitable for Zone 2.

Electronics Operation Algorithm

Fan with Timer (T): Starts after actuation of an external switch (e.g., light switch). Control voltage is supplied to terminal LT (ST). When control voltage is off, the fan continues to operate for a set time (2-30 minutes).

VT Model: Turned on and off by a pull-cord switch.

Fan with Timer (T1): After the switch is turned on, the fan starts with a turn-on delay (0-2 minutes). After the switch is turned off, it continues to operate with a turn-off delay (2-30 minutes).

Fan with Timer and Humidity Sensor (TH/VTH): Starts when control voltage is supplied to LT (or via pull-cord for VTH) or when indoor humidity exceeds a set point (~60%-90%). After control voltage is off or humidity drops, the fan runs for a set time (2-30 minutes).

Adjustments:

• To set maximum humidity setpoint (90%), adjust the potentiometer to H_max.
• To adjust turn-on delay time, turn knob T clockwise to increase, counter-clockwise to decrease.
• To adjust humidity set point, turn knob H clockwise to increase, counter-clockwise to decrease.

CAUTION! The timer circuit is live. Disconnect power before adjustments. Use the provided plastic screwdriver for adjustments. Do not use metal tools.

Symbol Description: Two crossed-out tools (metal screwdriver, knife) indicate prohibition of their use for circuit board adjustments.

Technical Maintenance

Maintenance should be performed at least once every 6 months.

Maintenance Steps:

• Disconnect power supply and ensure electricity is off.
• Remove front and decorative panels; wipe the fan with a dry cloth or brush.
• Clean the front panel under running water.
• Wipe fan surfaces dry.
• Reattach the front panel.
• Connect power supply.

CAUTION! Do not allow water or liquid to contact electrical components.

Storage and Transportation Regulations

• Store in original packaging in a dry, ventilated premise (temperature +5°C to +40°C, humidity up to 70%).
• Storage environment must be free of aggressive vapors or chemical mixtures that could cause corrosion.
• Use suitable machinery for handling to prevent damage.
• Follow cargo handling requirements.
• Transport in original packaging, protected against precipitation and mechanical damage, in the working position.
• Avoid sharp blows, scratches, or rough handling.
• Before initial power-up after low-temperature transport, allow the unit to warm up for 3-4 hours.
