DESIGN AND OPERATING PRINCIPLE

The fan casing is made of plastic.
The extract spigot with a non-return valve is attached to the fan to prevent back air flow.
In the upper part of the casing there is a terminal box, which contains terminals for connecting the fan to power mains and to electronics board, if available.
A single-phase electric motor with a centrifugal impeller with forward curved blades is fastened inside of the casing.
Depending on the model, the fan is equipped with a timer and a humidity sensor.

MOUNTING AND SET-UP

READ THE USER’S MANUAL BEFORE INSTALLING THE UNIT

The fan is a component part and is not designed for stand-alone operation.
The fan is designed for ceiling mounting and installation in the floor slab with fastening to the ceiling surface using removable rotary clamping brackets on the fan casing.
The fan installation location must comply with local building codes for this type of product.
Check the fan for mechanical damages prior to mounting.
Before mounting make sure the casing does not contain any foreign objects (e.g. foil, paper).
While installing the unit ensure convenient access for subsequent maintenance and repair.
The minimum distance between the fan and the ceiling should be at least 200 mm.
MOUNTING SEQUENCE

Use the template to mark the mounting location for the fan and make a hole in the ceiling Ø 300 mm.
The flexible air duct is pushed through the hole from behind the ceiling, from above. The air duct is installed on a spigot with a non-return valve.

Before installation, it is required to loosen the self-tapping screws on the rocking levers, thereby increasing the gap between the casing and the lever.
The spigot and the air duct are installed on the fan.

The fan assembly is inserted into the ceiling opening from the room side.
Secure the fan by turning the levers.

After installing the fan, it is necessary to clamp the self-tapping screws on the rocking levers to press the fan casing against the ceiling.
After installing the fan, it is necessary to clamp the self-tapping screws on the rocking levers to press the fan casing against the ceiling.

ELECTRONICS OPERATION ALGORITHM

Timer (T)
After turning on an external switch, such as a light switch, the fan turns on.
After the switch is turned off the fan keeps operating for a set turn-off delay time period, adjustable from 2 to 30 minutes.

Humidity sensor (H)
If the set humidity level in the room is exceeded from 60 % to 90 %, the fan turns on.
As the indoor humidity level drops down the fan keeps operating for a set turn-off delay time period, adjustable from 2 to 30 minutes, and then turns off.

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.
T on To adjust the fan turn-on delay time, turn the control knob Ton clockwise to increase and counter-clockwise to decrease the turn-on 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 %.

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

TECHNICAL MAINTENANCE

DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE OPERATIONS!
MAKE SURE THE UNIT IS DISCONNECTED FROM POWER MAINS BEFORE REMOVING THE PROTECTION.

The technical maintenance includes periodic cleaning of the surfaces from accumulated dust and dirt when the fan is disconnected from power supply. The impeller cleaning procedure is shown below. The impeller blades require thorough cleaning from dust and dirt once in 6 months.
