5 Maintenance 5.1 Important Danger • • Topvex FC Compact Air Handling Unit Make sure that the Mains supply to the unit is disconnected before performing any maintenance or electrical work! All electrical connections must be carried out by an authorized installer and in accordance with local rules and regulations. Warning • • Although the Mains supply to the unit has been disconnected there is still risk for injury due to rotating parts that have not come to a complete standstill.
5.3 Maintenance instructions 5.3.1 Open the doors Topvex FC The side hatch is opened by unscrewing 5 screws (figure 4.) Lower the door carefully. Compact Air Handling Unit Fig.
5.3.2 Changing Supply/Extract air filter Topvex FC The 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. Compact Air Handling Unit When this occurs do the following: 1. Replace the filters with new ones as described below. 2.
5.3.3 Checking the heat exchanger Topvex FC 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 (figure 6). Compact Danger • • • Air Handling Unit Risk of personal injury! The heat exchanger is heavy. There is a risk that the heat exchanger falls out of the unit.
5.3.4 Checking the fans Topvex FC 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 are easily taken out from the unit (figure 7) by loosening 4 screws and disconnecting the fast couplings to the electric wires. Depending on the accessories installed, remove the tubing next to the fast couplings for the extract air fan or both the extract air fan and supply air fan.
5.3.8 Changing the Internal Battery Note: This procedure requires knowledge of proper ESD protection; i.e. an earthed wristband must be used! Topvex FC 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.
6 Troubleshooting Note: 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. Topvex FC 1. Fan(s) do not start • Check if there are any alarm messages • Check that the fuses are not defect (pos.9 figure 2) • Check the settings in the control panel (times, week schedule, auto/manual operation etc.) 2.
