DESIGN AND OPERATING PRINCIPLE

Exhaust air duct with a non-

return valve

Terminal box Decorative panel

Casing

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

1. Use the template to mark the mounting

location for the fan and make a hole in

the ceiling Ø 300 mm.

2. 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.

3. 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.

4. The spigot and the air duct are installed

on the fan.

5. The fan assembly is inserted into the

ceiling opening from the room side.

6. Secure the fan by turning the levers.

7. 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.

8. Install the decorative panel (purchased separately for the HBF model) on the fan

casing. The panel is mounted in accordance with the User’s manual for the decorative

panel.
