1. Functional Description
See ”8.8. Menu tree” at page 24 for component
description.
Cold outdoor air passes through one half of the rotor
(HR-R), while warm extract air passes through the other
half, without the two mixing. Using this principle, a large
proportion of the heat in the extract air is transferred
to the supply air - the heat store principle (see system
sketches). If the outdoor temperature is extremely low, a
thermostat-controlled heating element (EB) also ensures
that the supply air has the desired temperature. This
supply air is passed via ducts and valves to living rooms
and bedrooms. The extract air is extracted either from
WKHVDPHURRPRUYLDGRRUJDSVRYHUȵRZJUDWLQJVWR
toilets and wet rooms. The used air is passed via a duct
V\VWHPEDFNWRWKHXQLWJLYHVR΍LWVKHDWDQGLVH[SHOOHG
from the building via a roof cowl, combi-box or wall
grating.
When there is no need for heat recovery (for example in
the summer), the rotor stops.

1.2. OPERATION OF KITCHEN HOOD
A - Knob for damper and for forced ventilation
B - Pushbutton for light
When cooking, open the damper by turning damper
switch A.
1) Turn the knob to level 1. The damper will be half
open.
2) Turn the knob to level 2. The damper will be fully
open.
3) Turn the knob to level 3 and the unit will increase the
air volume to speed 3 (forced ventilation).
4) You will need to turn the damper back manually

NOTICE! If the kitchen hood is used
often, the extract air fan must be
checked and if necessary cleaned
every four to six months.
The fans are removed as follows:

installed, it is not usually necessary to clean the rotor.
If for various reasons it should still be necessary, dust
can be removed with a soft brush. Further cleaning is
possible if you remove the rotor, spray it with fat-soluble
detergent and then blow it clean from the opposite
side. Distance approximately 60mm and max. pressure
8,0 bar. Ensure that the motor is not exposed to water
during cleaning. Ensure that all seals around the rotor
are intact and tight.
2.4. EXTERNAL CLEANING
Many kitchen surface cleaners contain chemicals
that may damage the product’s plastic components.
Therefore use a soft cloth moistened with warm water
and a neutral detergent to clean the outside of the
product.
Important! Do not use abrasive cleaners or scouring
powder, as they will damage the colour. Products that

NORMAL Used under normal conditions. In this setting,
the air supply must be adjusted according to
current regulations.
MAX Used if there is a need for increased air
supply on account of increased occupancy or
a higher humidity level, for example during
showering or when clothes are being dried.
This setting is usually used for limited periods
of time.
