If you are going into the unit then you first have to remove any kitchen furniture front door, if so is mounted on front of unit. On these pictures, you can see the ventilation unit with white coated cooker hood. There are also variants with hoods in brushed stainless steel. To open the front hatch you first have to untighten those four screws you find in each corner of the unit. When hatch is to be mounted back on the unit try to use almost same torque on all four screws. Then put the kitchen furniture front door back on place.

393829‐2 Rev 1: 19.04.2017. KJK Before any access into the electrical connections boxes, power must be disconnected by pulling out the plug from the socket. Only authorized persons is allowed to enter into the electrical connection boxes. 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 just can remove the black plug and you then can see the adjusting knob and the RH% scale. If a need for better insight or do not see the adjustment scale sufficient so one should remove the entire cover of this control board.

The sensitivity for the integrated sensor you can adjust from 50% (low) to 90% (high) in accordance to what are the need. The arrow points the value chosen. If you have a second external sensor that means you need to adjust that one from its settings. Replace the cover and / or plug after finish adjusting. Replacing the filter. The filters should be replaced every 6. 9. or 12. months. Should be extracted without use of any tools. Remember to enter the control panel menu (4.3 Filter) and press Filter OK after the filters has been replaced. To guarantee optimal properties of the ventilation unit, use the original filters from EnSy. The use of spurious filters will limit the warranty on the product.

Clean parts with mild soap and water Do not expose the rotor motor or connector for moisture. The exchanger you also can clean with mild soap and water. Do not use ammonia‐ containing detergent, as this will prey on and discolor aluminum in rotary heat exchanger. Flushed with hand shower and blow gently clean with compressed air. Ensure that the screws are tightened sufficiently so that they do not come loose during operation. Preferably use a screwdriver to tight the screws. If use of electrical screwdriver, make sure that you use low torque to prevent destroying the threads in the sheet metal parts. To make sure that the drive belt can adjust itself into correct position you must rotate the exchanger some few turns. Then insert back into the ventilation unit. Be sure that rotor exchanger is properly inserted in all the guides inside the unit. If not, this can lead to vibration in the system and internal air leak in the unit.

AHU‐200 KV and KH SLIM is designed for heat recovery with air volumes of up to 200 m³ / h. The energy from the exhaust air is transferred to supply air through the rotary heat exchanger where the air streams pass each other without making contact. The unit has a built in‐heater for supplementary heating of supply air. Humidity sensor for forced ventilation is integrated into ventilation unit The unit can also connect additional equipment. Pulse switch for controlling the forced ventilation, for example, wet rooms or bathrooms, sensor for carbon management and switch management away / home function. Control of these options are integrated into AHU 200‐KV and KH. AHU‐200 KV and KH SLIM is supplied in painted finish, tested and ready for operation.

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.

393829‐2 Rev 1: 19.04.2017. 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. In areas with extremely low winter temperatures, additional insulation must be used. Total insulation thickness must be at least 100 mm. Side 27 We reserve the right to change technical data without notice. http://www.ensy.no ...
Inlet diffusers, extract louvers and cooker hood Supply air diffusers have to be placed in the living area such as bedroom and living room, while the exhaust air louvers are placed in wet areas (bathrooms, laundry, etc.), toilet and kitchen NB: Although there is a cooker hood integrated in the unit it also must be mounted separate exhaust louver in the kitchen In AHU‐200 KH and KV the 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. NB! The cooker hood is 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. 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.
