FOLLOW THE USER’S MANUAL REQUIREMENTS TO ENSURE DURABLE AND
TROUBLE-FREE OPERATION OF THE UNIT.
Disconnect the unit from power supply prior to any connection, servicing, maintenance, and repair
operations.
Only qualied electricians with a work permit for electrical units up to 1000 V are allowed
for installation and maintenance. The present user’s manual should be carefully read
before beginning works.
• Single-phase power mains must comply with the acting local electrical norms and standards.
• Fixed electrical wiring must be equipped with an automatic circuit breaker.
• The unit must be connected to power mains through a QF automatic circuit breaker integrated
into the fixed wiring system. The gap between the circuit breaker contacts on all poles must be
not less than 3 mm. Check the unit for any visible damages of the impeller and the casing before
starting installation. The casing internals must be free of any foreign objects that 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 noisy operation. Misuse of the unit and any unauthorised modifications are
not allowed.
• Take steps to prevent ingress of smoke, carbon monoxide, and other combustion products into
the room through open chimney flues or other fire-protection devices. Sufficient air supply must
be provided for proper combustion and exhaust of gases through the chimney of fuel burning
equipment to prevent back drafting. Transported air must not contain any dust or other solid
5

impurities, sticky substances, or fibrous materials.
• Do not use the unit in a hazardous or explosive environment containing spirits, gasoline,
insecticides, etc.
• Do not close or block the intake or extract vents in order to ensure the efficient air flow.

BRIEF DESCRIPTION
The unit described herein is an axial fan for exhaust ventilation of small to medium-sized premises heated during winter.
The fan is designed for connection to ø100 mm air ducts.
This fan model includes a back valve that prevents air back drafting when the fan is off.
OPERATING GUIDELINES
The fan is rated for connection to single-phase AC 220...240 V/50 Hz power mains.
Air flow direction in the system must correspond to the direction arrow on the fan casing.
Hazardous parts access and water ingress protection rating is IP45.
The fan is rated for operation at the ambient temperature ranging from +1 °C up to +45 °C.

INSTALLATION AND SET-UP
The fan is designed for wall or ceiling mounting with direct air exhaust to the ventilation shaft or into the round air duct of
matching diameter.
The fan provides rated airflow (6, 8, 13 and 15 l/s) when the installation conditions are met according to one of the installation
charts (see Fig. 3-5) and the J1 jumper is selected correctly (see page 10). In the other case, the performance will differ from
the one stated in the User’s manual.
Fan installation sequence:
Step 1. Cut off power supply and make sure electricity has been turned off (Fig. 6).
Step 2. Lead the power cable to the ventilation hole (Fig. 7).
Step 3. Remove the front panel from the fan. Then remove the circuit board cover (Fig. 8).
Step 4. Mark and drill holes for mounting the fan and then install the fan (Fig. 9-11).
Step 5. Connect the fan to the electric mains according to the connections diagram (Fig. 16).
Step 6. Install the jumper located on the control board in the position corresponding to the mounting diagram.
Step 7. Cover the casing with a front panel (Fig. 12) and a decorative panel (Fig. 13).
Step 8. Supply power voltage to the fan (Fig. 14).

FAN OPTIONS
Quiet-dMEV 100 DC (V) Т fans are equipped with a turn-on and turn-off delay timer. The unit operates at the set constant
speed. VT models are equipped with a cord-operated switch.
The fan switches to the intensive mode upon control voltage application to input terminal LT by an external switch (e.g.
indoor light switch). Upon control voltage removal the fan continues to operate in the intensive mode for the period of time
set by means of a DIP switch.
Quiet-dMEV 100 DC 12 fan is rated for connection to safe 12 V/50 Hz power mains.
Quiet-dMEV 100 DC (V) TH fans are equipped with a turn-off and turn-on delay timer when the humidity level is exceeded.
The fan switches to the intensive mode upon control voltage application to input terminal LT by an external switch (e.g.
indoor light switch). Upon control voltage removal the fan continues to operate in the intensive mode for the period of time
set by means of a DIP switch. The V (TH) models are equipped with a cord-operated switch.
FAN OPERATION SETUP
THE TIMER CIRCUIT IS LIVE.
MAKE SURE THE FAN IS DISCONNECTED FROM POWER SUPPLY.
The fan is set up by changing the DIP switch position.
To access the DIP switch take off the face panel and remove the rubber plug (Fig. 15).
The fan is supplied with a special plastic screwdriver to toggle the DIP switch without damaging its components.

* — This mode provides for changing the humidity threshold and fan speed selection in automatic mode, independently choosing the
optimal threshold for the room in which the fan is located. The choice of the fan operation algorithm is determined by analysing the
statistical data of the humidity level in the room.
