Maintenance | 4.5 Free cooling 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. Note: The following is only valid if the free cooling function is set to Active in the program menu. In order for the free cooling function to work, a total of 3 temperature sensors (outdoor, supply and extract/ room) are required. Free cooling is only activated when the following starting conditions are met.
18 | Maintenance 5.1 Changing air filters The bag filter cannot be cleaned and must be changed when necessary. New filters can be ordered from Systemair. Operation 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. This will trigger an alarm in the control panel. Re-set the alarm after filter change, see Alarm settings, Alarm limits, Service alarm in the Control panel.
Maintenance | 5.2 Checking the fan Even if the required maintenance, such as changing of filters is carried out, dust and grease may slowly build up inside the fan. This will reduce the efficiency. The fan may be cleaned with a cloth or a soft brush. Do not use water. White spirit can be used to remove accumulations which are otherwise difficult to remove. Allow drying properly before use.
20 | Maintenance 5.6 Changing the internal battery Note: This procedure requires knowledge of proper ESD protection; i.e. an earthed wristband must be used! When the alarm ”Internal Battery” is activated and the battery LED lights up red, the battery for backup of program memory and real-time clock has become too weak. The battery is replaced as described below. A backup capacitor saves the memory and keeps the clock running for at least 10 minutes after the power supply is removed.
Troubleshooting | 6 Troubleshooting Should problems occur, please check or correct the following before contacting your service representative. Always check if there are any alarms active in the control panel. 1. The fan do not start • Check that the fuses are not defect. • Check the settings in the control panel (time, week schedule, auto, manual operating etc.). • Check if there are any alarm messages. 2. Reduced airflow • Check the settings of Normal and reduced fan speed.
22 | Service 6.1 Alarms The alarm button (pos.1, figure 2) opens the alarm queue. When pressing this button active and non-acknowledged alarms will be displayed in the menu window. The alarm-LED (pos.2, figure 2) is flashing if there are non-acknowledged alarms and steady if the alarms are still active but have been acknowledged. If there are multiple alarms, use UP/DOWN to move between them. An alarm can be acknowledged or blocked by using OK and UP/DOWN.
