5 Maintenance 1 Warnings 5.1 Important The following admonitions will be presented in the different sections of the document.
5.3 Maintenance Instruction 5.3.1 Changing Supply/Extract Air Filter and Pre-Filter 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. When this occurs do the following: 1. Replace the filters with new ones as described below 2.
5.3.2 Checking the Heat Exchanger After extended use dust may build up in the exchanger and block the air flow. It is important to clean the exchanger regularly to maintain high efficiency. The complete rotating heat exchanger block can be taken out of the unit (figure 7) in the smaller models to facilitate cleaning and maintenance. Wash in hot soapy water or use pressurized air. Do not use detergents containing ammonia. Check at least once a year that the exchanger rotor rotates easily.
5.3.4 Checking the Hot Water Heating Coil After long periods of operation (usually several years) dust may have deposited on the surface of the coil. This may reduce coil capacity. The coil can be cleaned with a pressure washer with misting jets, or with compressed air. Cleaning should be carried out carefully so as not to damage the coil’s aluminum fins. Once a year the coil water circuit needs to be vented to maintain the coil capacity 5.3.
1 Remove the cover by pressing down the locking torques at the edge of the cover using a small screwdriver, and at the same time pulling the edges outwards. 2 Grip the battery firmly with your fingers and lift it upwards until it rises from its holder. Press the new battery firmly down into place. Note that to preserve correct polarity, the battery can only be inserted the “right way round”.

5.4 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. See section 4.3 to learn how to navigate through the control panel menu. For more information on the alarm designations go to the Systemair website (www.systemair.com/na/North-America/) and download the controller user manual. 1.
