If any electrical components are damaged, they must be replaced by the manufacturer, dealer or a qualified person in order to avoid dangerous situations.. Adjustment of the unit. A humidity sensor is, from factory, mounted inside the unit. It is set to “0” that means it is set to not active. After startup, where the unit is placed into a new building with high humidity, you can let this humidity sensor be turned off for a period to avoid the full speed of the fan at night. To get the humidity sensor to operate as intended, you need at one time to put it active. Than you need to set the switch in position "1". If the ventilation unit is placed in a house without high humidity, you should switch to position "1" after you putting ventilation unit into operation. This switch will also affect any extra external humidity sensor that is plugged into the device. Adjusting the humidity sensor. If it is necessary to adjust the sensitivity of the humidity sensor then you must, on older models, remove the cover, which is over the control board where this adjustment is located. Unplug the supply before removing the cover. On newer models, you just can remove the black plug and you then can see the adjusting knob and the RH% scale.

Tumble dryer must not be connected to the ventilation unit, but have its own duct to the open air. Duct should be kept covered during storage and installation. Location of the exhaust grid / roof cowl must also meet current building conditions, as well as any requirements of local building authorities. All inlet and outlet of the unit must be connected to the piping. Pairing of duct sections. All joints between ducts, T‐pipes, bends, reducers, etc. have to be “locked" by using special tape or at least 3 pieces of self‐tapping screws. Sound reduction To avoid disturbing noise from blowers in living area installation of sound‐absorber (silencer) in the duct for supply and extract air recommended. (length = 0.9 meters each section) To prevent sound transmission between rooms via the duct system, and reduce any noise that occurs in the duct system, is also is recommended a silencer in front of each supply diffuser in the living area.

393805‐2 Rev 0: 05.05.2017. KJK Condensation/isolation Isolation is necessary to safeguard thermal‐, sonic‐ and fire considerations at the plant. Most often it is a combination of these are due to isolate. Reasons for thermal insulation of ventilation ducts are: obtain good heat economy by limiting heat loss achieve a specific outlet temperature of the ventilation air. preventing condensation on either the inside or outside of the duct. Heating costs reduced by preventing the heat supplied in ventilation air can be transferred to unheated surroundings. If the ducts are positioned in a cold environment, such as in an attic, where the temperature is significantly lower than the ventilation air, there is a risk of condensation inside the ducts. This can be prevented by isolating the channel exterior. In this case, the channel wall being diffusion and would therefore insulate externally with a diffusion material of mineral wool. It can also be used insulation tubes (100 mm mineral wool) with plastic diffusion barrier pulled over the ducts. The same applies to insulation of pipings between the unit and diffusors, bringing the cooled air up to the rooms. Note! Remember good overlap of diffusion barrier and tape all joints with duct tape. Fresh air and exhaust duct should always be condensation insulated throughout its length. Proper performance of the unit connection is especially important. Similarly, isolate all other ducts for cold and uninsulated room. Page 26 We reserve the right to change technical data without notice. http://www.ensy.no ...
Note: Although the cooker hood connected to the unit it also must be mounted separate exhaust . louver in the kitchen The AHU 300 cooker hood outlet is led directly to the exhaust fan without the smell and pollutants carried through the heat exchanger. In order to achieve heat recovery from ventilation due to exhaust louver in the kitchen, therefore, this exhaust louver has to be connected together with the exhaust from the wet cells Cooker hood must be equipped with dampers which are dense in the closed position (without opening for the basic ventilation). If there are any «leakage» in the extract pipe from the cooker hood when the cooker hood isn’t activated then there will be a “Rotor fault” alarm. It is very important that there are a signal from cooker hood connected towards the KV plug outside the unit to avoid this “Rotor fault” alarm. Exhaust air louvers can be mounted in the ceiling or wall. Supply air diffuser can be mounted in the ceiling or "low wall". In "low wall" must sectorial aperture positioned so that supply airstream carried upwards along the sloping ceiling. Supply in the wall at the horizontal ceiling must have “throwing direction", so that air enters the room along the ceiling. Air supply via the outlet valve allows air jet throw length, and the exhaust air diffusers can therefore be used as supply air diffuser in the wall when there is ridge ceiling. The diffusers should be mounted in frames, so that they can be easily removed for cleaning. 4 Setting the airflow. As default setting may supply air diffusers core is opened from 5 to 7 turns from the closed position and locked with a centre nut. Exhaust louvers core is opened 10 turns from the closed position and locked with a centre nut. For adjustment of air flow to each room the settings for the diffusers must be measured.
