Page 5: Unit Type
Unit type Product description Comfort 252/302 Top is a ventilation unit with heat recovery. The unit is intended for air volumes of up to 253/345 m /h at an external duct pressure of 100 Pa. The unit is used primarily in residential buildings. Due to its low sound level it is particularly suitable for ventilation in apartments. The unit ventilates the dwelling by drawing out damp and vitiated air through valves placed in, for instance, bathroom, lavatory, kitchen and utility room. -

Every autumn it is therefore important to check that there is water in the water trap. However, if you install a Nilan water trap with ball, the ball will ensure permanent function of the water trap. This saves you refilling the water trap manually every autumn to ensure that it works. -
Page 10: Vibration Absorbers
It is important to ensure that the ventilation unit does not transfer vibrations to the building. The ventilation unit should therefore be placed on a vibration absorbing material. Nilan can supply effective vibration absorbers to place under the ventilation unit. They are sold in packs of 4. Flexible sound damper To make it esay to service the unit in the future, we recommend that you fit a flexible connection between the unit and the duct system. -

sensor If the extent to which a dwelling/building is used varies considerably, you will benefit from installing a CO -sensor to control the air exchange. The CO -sensor measures the CO -level in the extract air. It then regulates the fan speed level accordingly. ATTENTION In order to be able to connect up a CO -sensor, the ventilation unit must have an expansion PCB. -
Page 31: Joint Alarm
Joint alarm It may be difficult to notice alarms if the unit is located in a place where access is difficult or infrequent, and if the control panel is locat- ed in the same place. An external alarm indicator in the form of an electric bulb or an acoustic signal can be connected to the ventilation unit and announce when an alarm occurs. -
Page 32: Plumbing Installation
USEFUL INFORMATION As an accessory, Nilan can supply a water trap with ball. When the water trap dries out, the ball closes it off and ensures that air cannot be drawn into the ventilation unit. When condensate water is formed again, it will lift the ball, and the water will be able to drain away without problems. -

This is to avoid vibrations from the unit being transmitted to the duct system. It will also make it easier to move the unit, which may be necessary during future services of the unit. Nilan can supply Soundflex tubes that you can use as flexible connections between the ventilation unit and the duct system. They will also reduce sounds from the system considerably. -
Page 40: Supply Air
Extract air Install the extract air valves in high-humidity rooms and place them strategically where they can extract humid and vitiated air from the dwelling/building most efficiently. High-humidity rooms are, for example: • Bathroom • Lavatory • Kitchen • Utility room Supply air Install supply air valves in living areas. -
Page 41: Balancing
Balancing Important information ATTENTION To ensure the ventilation system operates optimally, it is important that it is balanced correctly. We recommend that experts do this. It is important to measure the total supply air and the total extract air. The system must have a minimum vacuum, which means it draw out more air than it blows in. -
