Page 10: Free Cooling Description
| Product description Free cooling description This function is used during the warm period to save energy by using cold outdoor air, e.g. during night time, to cool down the building and thereby reducing the need for cooling during the day time. Note: The following is only valid if the free cooling function is activated in the program menu. -
Page 11: Defrost Function
Defrost function | Defrost function By measuring the pressure difference over the exchangers extract/exhaust side the need for defrosting can be de- tected. The differential pressure transmitter is auto calibrated by the system to obtain the correct pressure in relation to the airflow. -
Page 12: Maintenance Instructions
Changing supply/extract air filter The bag filter cannot be cleaned and must be changed when necessary. New filters can be ordered from Systemair. Op- eration time between filter changes depends on the air pollution at the installation site. A differential pressure switch indicates when it’s time to change the filters. -
Page 13: Checking The Heat Exchanger
Maintenance | 4.3.2 Checking the heat exchanger After a long time of use dust may build up in the exchanger and block the airflow. It is important to clean the exchanger regularly (once a year) to maintain high efficiency. The heat exchanger can be taken out of the unit for maintenance. Wash in hot soapy water or use pressure air. -
Page 14: Checking The Fans
| Maintenance 4.3.3 Checking the fans Even if the required maintenance, such as change of filters, is carried out dust and grease may slowly build up inside the fans. This will reduce the efficiency. The fans can be dismounted by loosening the bolts which attach the rack to the units inner wall section. The complete fan rack can then be pulled out after all the attached fast couplings to the electric wires and the two tubes have been disconnected. -
Page 15: Checking The Hot Water Heating Battery
Maintenance | 3 For the exhaust air side the fans are dismounted by loosening two bolts (pos.1) for size 3-4 and three for size 6-11 and remove the rail (pos.2). 4.3.4 Checking the hot water heating battery After long periods of operation (usually several years) dust may have deposited on the surface of the battery. This may reduce batteries capacity. -
Page 16: Checking The Outdoor Air Intake
| Maintenance 4.3.7 Checking the outdoor air intake Leaves and pollution could plug up the air intake grille and reduce the unit’s capacity. Check the air intake grille at least twice a year and clean if necessary. 4.3.8 Checking the duct system Dust and grease settlements may build up in the duct system even if filters are changed regularly. - Page 17 Ver.
